Trunk ‑ Stock Sync & Bundling

Great app for keeping inventory synced between Amazon and Ebay. We have been using it for years without any problems. James is quick to help with any questions and requests that may arise.

You know your business is growing when things start to break. During the Faire Winter Market I oversold several products across my sales channels, which was incredibly stressful and made it clear I had outgrown my inventory system. I discovered Trunkthrough a mastermind group and decided to try it. Setup took about an hour and it immediately synced with everything I use. It was one of the fastest and easiest tools I’ve ever implemented. The biggest surprise was how much time it gave back. I didn’t realize how many hours I was spending tracking and correcting inventory until Trunk automated the process. Now everything stays accurate across platforms without constant checking. I also appreciate how clean and focused the system is. It has exactly the features I need without unnecessary tools, and when I contacted support for a report they were quick and helpful. I’m planning a move from Squarespace to Shopify later this year, and knowing Trunk will handle the transition smoothly gives me confidence. I run an educational program that helps artists build product businesses, and Trunk is the only inventory system I recommend.

Trunk is working seamlessly to track inventory across my Shopify and Etsy stores - it's great! I was apprehensive that it would be complicated to set up, but needn't have been - it was so simple and really didn´t take long at all (minutes rather than hours!).

I searched for a long time for an app that could automatically sync inventory between Shopify, Etsy, and Square. Trunk has been exactly what I was looking for. The support has been excellent, with regular check-ins and guidance whenever I needed help. I think Everything has been working well.

Great experience using Trunk. Very simple & user friendly!

We've had a great experience with Trunk. It handles bundling products with the same SKU in our Shopify store exactly as we needed, and the setup was simple. Their customer service is outstanding—responsive, knowledgeable, and always willing to help. Highly recommend!

Trunk has been an absolute game changer for my business. I update my inventory in ONE place, and it automatically filters across all of my channels. I wish I'd signed up years ago. If you're running a busy business, get this app now — it's your one-stop shop for keeping up with constantly changing inventory. It's worth every penny!

Love it! Does exactly what I want! Simple to use, no nonsense. syncs all inventory across all platforms live. Saves our business heaps of time! Best decision we made this year!

REALLY excited to have been referred to Trunk. SUPER easy to set up and is smooth like butter. As a small business owner, we have to be nimble with how we operate and quick to solve problems! Trunk helped and we're super grateful!!

The best solution for us to manage inventory between two Shopify stores. Easy to install, fast support. Really recommend for stock management.

I used to manually manage my inventory over 3 separate websites. It was time consuming and also very daunting, Not to mention it would lead to inaccuracies across the different website inventories. We tried a couple different apps through Shopify to help none of them worked or didn’t work like we wanted them too. We tried Trunk out and as soon as we had it figured out and all site linked it was like magic. A change to one site and the sync happens at all sites linked. To change inventory on all site you only need to change it on any site you choose or through Trunk itself and the rest is automatically update. Solid app. Highly recommended

Trunk is taking hours of mental load from me by seamlessly tracking my inventory between Faire and Etsy.

The software is excellent. It successfully solved our biggest challenge: syncing our Amazon and Shopify inventories. The platform is easy to set up and use, and the customer service team is highly responsive. I would recommend it to anyone.

Trunk has been a great tool for linking my physical store system to my website, I trialed a few different apps to make this happen for us, but each one had certain flaws that meant it wasn't right for us, but Trunk was super quick and easy to use, does exactly what it says on the tin, no hoops to jump through, no long set up procedures, just really easy, simple functionality. I would definitely recommend!

Super impressed with Trunk so far. The tool is simple and easy to plug in and start using right away. Perfect for a small business! Their support team has been fantastic, answering questions quickly and helping me get everything set up smoothly.

Trunk has been an OUTSTANDING solution for my business. We have a bespoke use case, and syncing inventory between multiple channels and even multiple Shopify stores has been a challenge for us. Trunk simplified all of that into something that just works. Plus, support was there to help with some of my weird use cases! Definitely my new go to inventory management app.

Really useful app for managing our inventory. It made it much easier to track kits properly and gave us a clear view of what was actually in stock at any time. One of the biggest improvements for us was eliminating duplicate entries, which used to create a lot of confusion. Overall, it brought much more structure and accuracy to our inventory management.

Trunk has been an essential tool in allowing us to expand our inventory across multiple sales channels without have to keep track of seperate stock levels. Very pleased with the team and the service we have received.

Trunk solved a big problem for our inventory management on Shopify. The problem we were having could not be solved by out-of-the-box Shopify inventory management and I spent months trying to find an app that could correctly deduct stock for our custom sets. Nothing worked until I found Trunk. Very happy with the software and very easy to set up and use. Will continue to use going forward!

Trunk was easy to set up and just works. It's freed me to spend time on more important ways to grow my brand!

I had used a few sync apps in the past but always got into some problems. we run multiple websites and B2B sites and some retail outlets, so having stock info correct is vital - we have been using trunk now for a month and its been problem free and runs happiliy in the background syncing for us from all the sites without anyone being the master (unless asked) this has changed the amount of manual work per week by hours.

At SEMRail, we manage several Shopify brands, including PMUHub, which is the leading platform for permanent makeup professionals and clients in the U.S. We used to struggle with managing inventory across our stores, but Trunk has completely resolved that issue. The setup took just a few minutes, the syncing process is seamless, and it has provided us with complete operational peace of mind.

After trying a couple other apps for syncing inventory for 2 websites, we are super-exicted to have Found Trunk - very simple to setup, and it does exactly what it's supposed to! We Rate them 5 out of 5 stars! TheMusicStand.com

Love this app! Really helpful in synchronising my stock across multiple sales channels including my bundles . The team is also very friendly and helpful! highly recommend xx

Trunk allows Iron & Blossom to keep inventory in sync across all sales channels, so customers always have real time stock visibility into the latest cast iron and metal home decor products, without ever needing manual updates.

Trunk is a fantastic tool for all sorts of bundles and inventory management. It has allowed us to bundle products together, whether it be a combination of items or multiple quantities of items, and it keeps our inventory numbers perfectly accurate. Its real-time updates make working with it very efficient. I would highly recommend Trunk if you ever want to group multiple SKUs together and not have inventory headaches.

Running an online cigar store means juggling inventory for singles, 5-packs, samplers, and full boxes, and before Trunk, that was a logistical mess. Trunk made it simple. The real-time kitting and inventory syncing has completely streamlined how we manage stock across products that share the same underlying units. What really stands out to me, though, is the support. The Trunk team is incredibly responsive; every time we’ve had a question or needed clarification, they’ve been quick to reply and genuinely helpful. It’s clear they care about making their platform work for your business. If you're in eCommerce and dealing with kitting or bundling, Trunk is one of those rare tools that actually delivers on what it promises.

Trunk has been a game‑changer for our business. We sell vintage toys on Shopify, Etsy, and eBay, and keeping inventory accurate across all three platforms was always a challenge. With Trunk, everything stays perfectly synced, which means we can focus on selling instead of worrying about overselling or constant manual updates. It’s simple, reliable, and an absolute essential for running multiple eCommerce platforms. Honestly, our business wouldn’t be nearly as successful without it. We highly recommend Trunk, it's definitely worth the money!

Trunk is a game-changer! I no longer have to worry about updating inventory manually across multiple platforms. I love being able to see all my listings in one place—it makes it so much easier to stay organized and avoid missing anything.

This is one of the most functional products that streamlines our entire business and removed a hefty weight from our team. Easily the best money I've spent this year for productivity. Trunk team was able to sync all my Square inventory across 12 locations forcing it to act as one centralized inventory overcoming a massive hurdle that Square seems to continuously ignore for small mobile locations. This has been an absolute game-changer! Now, a customer can place an order at one location for pickup on our next day at that site and Trunk overwrites my inventory at ALL OTHER LOCATIONS so that I don't oversell what we actually truly have in stock for the week. On top of that, their team is AMAZING to work with. Solutions oriented, good listeners and designers to implement something that didn't natively exist. WHO does that anymore!? I was treated like a valued customer with respect and responsiveness. Couldn't love this product or team more!

At first, we couldn’t believe an app could handle inventory syncing this quickly. There's a lot of hype and empty promises out there, but very few tools actually deliver. After reading the overwhelmingly positive feedback, we decided to give it a try - and we’re glad we did. Trunk works exactly as advertised. Inventory is synchronized almost instantly, and connecting our marketplaces was straightforward. So far, we have nothing to complain about. Trunk saves us a lot of time and gives us a much clearer overview of our entire product range.

I have been really happy with Trunk. I can sync my Shopify, Etsy, Faire and Square shops so they all reflect the inventory I have on hand. A lifesaver!

The app is everything I've been searching for! Incredible results and the team is so helpful.

Trunk is absolutely amazing solution for inventory tracking. We have Etsy and Shopify store with thousands of gemstones, that is impossible to truck manually. Trunk is easy to install, sync everything, even tells us duplicated SKU! And always received 5 stars help support from Arturo. Highly recommend!

Trunk has been a game-changer for us! It seamlessly integrates our Shopify and Square accounts, making it easy to sell in-store and online while managing inventory across multiple platforms. It’s opened up new expansion opportunities for our business and saved us tons of time!

Trunk is the only app I’ve come across that actually handles bundled / kit/ parent products effectively. Gives the ability to accurately keep stock the website & marketplaces using a parent sku has made life so much easier! Thanks James!

Managing inventory across four sales channels used to be a complex, manual process—prone to errors and customer disappointment when items oversold. Since switching to Trunk, inventory tracking has become seamless and efficient. Now, when a product sells out, it automatically deactivates across all platforms, helping us avoid restocking delays, refund situations, and frustrated customers. What I appreciate most is Trunk’s powerful handling of made-to-order items with multiple variations. We can assign a “master” product with a shared quantity, so every variant draws from the same stock. When one sells, the inventory updates instantly across all variants—eliminating confusion and saving us hours of work. Thank you for an exceptional tool that’s streamlined our operations and helped us scale with confidence.

Absolutely excellent!!! This service saved me soo much hassle. We have a handmade jewelry brand so all of our items have to be removed immediately, this app allows me to crosslist without a worry, never fails to remove an item. ExportYourStore, Marketplace Connect, they all let me down, this small company was a God-send! Thanks Trunk.

Trunk solved bundles for us. Being able to make ANY product sync inventory with a parent SKU is key for us as an emerging brand, and Trunk allows us to simply set that up! Our inventory management is much simpler now as it is automatic. Thanks team.

I've tried many apps to sync my inventories, and I've always had some problems with it. Trunk is perfect, I already used it in an old store and I'm using it now in the new one, and the sync is immediate and doesn't fail! I highly recommend it!

Trunk is amazing. It helped us sync our inventory between Shopify and Etsy extremely easily. Its simple software that is easy to use and easy to setup. It just works!

Trunk has satisfied everything that I was looking for in an inventory program.

Needed a solution to keep track of inventory across multiple Shopify instances - Trunk came highly recommended and it hasn't disappointed. Install was straightforward. Updates have been lightning fast. A very neat piece of kit.

Trunk easily solved the issue of needing to pull both individual retail units, and wholesale bundles, from the same inventory AND across multiple sales channels. It's saving us countless headaches and we're no longer spending hours manually updating inventory counts.

I am so happy I found Trunk! It has helped me organize my inventory across my numerous platforms! I feel so much more organized!!

Trunk has been a game-changer for managing our inventory across multiple sales channels! With our multi-packs and various product variants, keeping stock counts consistent was always a challenge. Now, we don’t have to worry about separate stock counts for each product and channel, as everything syncs seamlessly. The customer support team was incredibly helpful, guiding us through the setup and ensuring we got up and running smoothly. Hopefully, they can add syncing for bundles that share same SKU in future updates. Overall, highly recommend for anyone looking to simplify their inventory management!

As a business owner, navigating the complexities of inventory management can often feel like an uphill battle. However, with the introduction of Trunk, the task has been transformed into a seamless and efficient process. This program has become an indispensable asset for my business, revolutionizing the way we handle inventory. One of the standout features of Trunk is its user-friendly interface. From the moment I began using the program, I was impressed by how intuitive and easy-to-navigate it is. Another highlight of Trunk is its seamless integration with other business systems, I can manage the inventory on Etsy and Faire at the same time. It has been amazing!!

Trunk has made is so easy and seamless to track my inventory from Shopify to Etsy and can even track inventory on Faire! I love using it for my business.

It makes keeping track of inventory between different platforms so incredibly easy. It saved my sanity!

I run three shops (two product based and one supply based) that all use the same inventory. Trunk has been a GAME CHANGER for my business.

Trunk has been a life saver. With selling on multiple channels, it was a monumental task to keep track of the inventory and make sure we didn't sell out on one of the channels and have an angry customer. With trunk, everything is updated on all the channels almost instantly. We've also noticed an increase in sales because instead of only listing a low quantity of a product, we can now list a larger quantity and know that if a purchase is made on one channel, it will immediately update on the other channels. Hooray for Trunk!!

Finding Trunk so easy to get to grips with and the team are very responsive when I've reached out. So happy that I have found a way to keep track of what's in stock and the product bundling is a JOY!

Trunk has helped our small business get back our time and assist in inventory management across Shopify and our POS system seamlessly. We do not have to manually add or delete inventory across these two channels. It has been a huge help and game changer for our business to easily track our inventory!

I sell on multiple platforms and managing inventory is quite stressful. I am beyond thrilled with Trunk so far! I had a really poor experience with a different company, so I was hesitant. However, Trunk has kept everything running smoothly and their support was great when I had to reach out. Thank you!

I was looking for an affordable option to help manage my inventory so I thought I would give Trunk a try. Wow! What a time saver. No glitches, always accurate and inventory updates within seconds! Very satisfied!

Seamless - easy to onboard without all the complications. It has been flawless. We have not had one issue. As long as the SKU's match, inventory is updated nearly immediately. Who would ever think it would be this easy and actually work as it is supposed to. Best program we have tried and we have tried a lot. We will be staying with Trunk!

I've been so happy with Trunk! I have a book business that sells across multiple platforms. Trunk was so easy to set up and the days of double selling are finally over. Thank you James for the great service!

We just recently started using Trunk and it's been a breeze. It is user friendly and simple to integrate in just a few steps. I'm using it to sync between 3 platforms and so far, the updates have been seamless.

Trunk really helped us solved a major problem we have while using both Square and Shopify. We are a tea shop that utilizes Square for all the restaurant side features and have moved to Shopify for our e-commerce features. Having those stock link up is vital to us so it's nice that Trunk does that for us automatically.

I've tried other solutions in the past to sync my shop inventory and they were too complicated and never worked quite right. Setting up Trunk was quick, easy, and it just works. So glad I found it!

Excellent app for stock keeping. Easy to set up bundles.

I'm using Trunk to keep track of the inventory of my original paintings in real-time between Shopify and Etsy. Extremely easy to set up and it gives me peace of mind if I sell a painting on one platform it is immediately removed from the other.

Trunk is seamless in integrating inventory between markets. Yes, there are some kinks to be ironed out; however, their customer support team is superb in figuring the challenges when it arise.

I’m really enjoying Trunk so far! It makes my life so much easier. Gone are the days of constantly counting inventory. A small business owner must-have.

simple and easy to use when you dont need shipping services to

Been using Trunk for nearly a year now, absolutely brill software, easy to use and perfect for keeping my stock in check and synced, highly recommended

Before Trunk we were manually updating our inventory on 3 of our selling platforms after weekly festivals and pop-ups. With our festival dates drastically increasing this became a hassle. Now with Trunk, as soon as we have a sale at a local event our inventory is updated on our Shopify and other sales platforms! This has been a huge help and has stopped us from over selling products which was disappointing online customers. Trunk was one of the BEST business decisions we have ever made!

I am an artist that makes sales and fulfillment both in person and through multiple online channels. Trunk has been great for getting my inventories synced across all the platforms. It was a breeze to get set up and tech support is easy to access withquick response times. I've only been using it for a few weeks and I'm already looking forward to being able to spend less time on inventory management and more time creating!

I've been selling on Etsy for 5 years and just started a shop on Shopify and just made my first sale there. So far inventory syncing is working great and there are no worries about over-selling. Just for start-ups and also due to current exchange rate (weak JPY against USD), I feel the cost for subscribing TRUNK is a bit high. But I definitely need this app for operating multiple shops. Great app.

Trunk offers an excellent solution that seamlessly integrates with the majority of my selling platforms. I opted for Trunk primarily due to its pricing, user interface and speed, over other applications. Although Trunk was the last app I tested, all of the preceding apps were substandard, with clunky interfaces, and some didn't even perform the tasks they offered. Fortunately, Trunk delivered a hassle-free solution that enabled my automotive parts stock to synchronise across various platforms, in the multiple variations I have for each product, precisely as advertised.

Trunk has made it possible to automate and include Etsy into my business. It's addressed the huge headache I was having with my stock system.

I am a long time etsy seller who finally branched out to open my own shopify store. I heard about Trunk through some forum posts and knew I would need the inventory management service; many of the items I handmake are one of a kind. I had some trouble in the beginning with variations not lining up and was ready to throw in the towel. However, the staff at Trunk was super patient and even let me have another free trial to make sure the service would work for me! I just officially signed up for a paid plan and I know it will be well worth the money.

Trunk was a lifesaver for us! After we created our product add on kits we realized that we had multiple SKUs that we needed to keep track of in our inventory. With Trunk it was so simple! Now when we add more sales channels we will already be set up! Highly Recommend

We had issues syncing 2 products with the same SKU in Shopify. This solved the problem in a heartbeat, could not have been easier. Joy to use.

Trunk is a must-have for any Shopify user who also sells on other platforms! It is very easy to set up, use, and adjusts inventory very quickly (pretty much instantly). I highly recommend it! I've been using this for 3 and a half years now and it has been a lifesaver.

At last! A simple, effective multichannel inventory syncing services that also does kitting & bundling without charging crazy prices or trying to also do shipping. Plays nicely alongside the usual shipping solutions and is the perfect solution for anyone taking that first step from a marketplace like Etsy into selling the same products on their own website. Looks like it will scale well to multiple channels and high SKU counts.

Seamless and lightning fast. Trunk calculates automatically how many quilt kits I can sell based on the amount of yardage I have in stock. No more manually calculating and adjusting the remainder on the bolt, no more overselling kits. Instead I get awarning when inventory of a kit runs low and can arrange my backorders in time.

Trunk has streamlined my inventory management process, I would highly recommend this app to every business!

Trunk has provided a simple, effective solution to an inventory road block that was holding me back from expanding my small ceramics business to multiple platforms. Even with limited, often one of a kind inventory I am able to sell my products on multiple sales channels without worrying about over selling or needing double or triple the inventory. Trunk works perfectly 99% of the time, and if there is an issue they are amazingly quick to solve it. I can’t recommend Trunk highly enough!

OMG Etsy, woocomerce and Shopify !Im very excited,I don't know if I can name any applications here, but if it can help other people I do! I've been split my inventories on Etsy and Woocomerce for 3 years, because no application works. I tested Square, Nembol, Litcomerce, Cedcomerce, none of them worked, but I'm like any other company. I have a sku and variations. When I saw the name Trunk, I was on Square in my account trying to fix my inventory yet again. I read it and said to myself ok Julie try it! I connected my 2 stores together and BANG! Everything works, it's amazing. After so many years of searching I found you. Thank you so much! Thanks a lot!

I run 3 online shops (Shopify, Etsy and EBay) and managing inventory between them was taking up valuable time every day. I have a lot of unique, hand-made items too (I hand-paint artwork in bleach onto clothing) so double selling isn’t an option for me. This was quick and easy to set up, works perfectly in the background and leaves you with more time to do proper work! Customer service has been excellent, pretty sure they’re adding extra functions I’d like in future too. Worth the price and recommended.

Trunk has been amazing for my handcrafted jewelry business, particularly during my busy seasons when orders are coming in constantly across retail and wholesale platforms. Trunk also offers a brilliant workaround to Shopify’s constraint on inventory management with variations: if I have a single pendant but the customer can choose chain lengths, I don’t want to manage inventory quantities for each of the 3 different chain lengths. Instead, with a single master SKU, Trunk will sync all the variations, and when the pendant is sold, the other variations all automatically go to zero and the item is marked as sold out. A complete time-saver! Trunk allows me to spend more of my time jewelry-making, growing my business, or just plain relaxing, instead of spending hours each month on multi-channel inventory management.

Trunk has solved all of my inventory management problems! I was missing sales and refunding orders because I could not keep up manually adjusting stock on every platform we sell on. Trunk integrated easily and seamlessly and has already paid for itself! I am no longer refunding orders because I’m out of stock. It was exactly what I was looking for!

We are very happy with the Trunk Inventory software. It is easy to install and very simple to use and syncs inventory extremely fast and accurate, no error. No more hassle to adjust inventory manually. Great customer service, highly recommended. Thank you team!

I've been in ecommerce for over a decade and have tried MANY inventory software. Trunk is hands down the simplest yet most effective solution out there. And it's made for small businesses - their monthly fee reflects that. Support has been AMAZING. Things seem to just work which seems like a low barrier but alternatives are too cumbersome or require complex workarounds to get what I need it to do. Trunk is perfect for me, which is simple SKU linking between listings in the same shop and in other sales channels. I'm hoping there'll be more interface features soon. Considering I tried Trunk out a few years ago and it didn't fit my needs at the time, and now it does, tells me they're actively working on improving their product. Very happy so far!

Trunk isn't the first inventory syncing software we have tried, but its the first one that worked perfectly the first time, and made the whole process easy.

With the discontinuation of Quickbooks Commerce, Trunk has been an amazing alternative to keep our inventory streamlined across multiple sales channels. The bundle feature in Pro account is essential for our box sets as well. I’ve already recommended this app to other small businesses!

I’ve been trying to sync inventory across a wholesale and retail site manually and was always forgetting something! Trunk was a perfect solution and has already helped take away that stress in the first day we set it up. Plus, I love that there’s room for growth if I decide to show on other wholesale sites!

Trunk has been exactly what I needed to allow me to sell on three platforms. It was easy to setup, get going right away and is spot on in syncing inventory on all three platforms. It is a very well thought out system and works great! I also love the inventory stock alert feature as well as stock lookup by SKU or partial product title.

Trunk is the perfect solution to an inventory problem I was having. I use another app for inventory of raw materials and manufacturing, but with the addition of Trunk, I am now able to sync inventory levels of manufactured goods across all of my platforms. This has already saved me hours of stress and frustration. After a busy fourth quarter last year and manually adjusting inventory levels across multiple platforms and accidentally overselling, I knew something had to change. Trunk is my failsafe for this year's holiday season and I look forward to the automation inventory adjustments of Trunk.

Trunk does a great job about syncing my inventory between shopify storefronts and is super super fast at doing so! The team has been responsive - I recommend checking it out!

Trunk has been vital in helping us link stock between our two Shopify stores together. Without trunk our business wont be able to keep track of inventory, and we'd be consistently letting customers down.

Well organized and easy to use. I had a bit of a challenge with setup but James was a great help.

You know, my company has been sync'ing a lot of products with other vendors for quite a long time so I feel qualified to speak about things. Trunk is a extremely easy to set up and use app, mismatched SKU matching works well and is a fast process. The sync times we see are very fast, in fact at one point today my team simply went from one tab on the browser to the other and the SKU count was already updated. Frankly, if you need to sync inventory this app is well worth considering!

We have been using Trunk for a few years now and we're very happy with the service. We originally used it to sync between Squarespace and eBay. But, recently we moved our online shop to Shopify. We were happy to see that Trunk integration was only a click away. With Trunk we don't have to worry about anything, when it comes to inventory keeping in sync. It's lightning fast and so is the customer service from James! Thanks Trunk!

Perfect programme to manage live sync inventory. Simple and effective in what it sets out to achieve. Really pleased with it!

Was on Woocommerce and spent 3.5 months trying to find a solution that does the inventory management I needed. Moved to shopify because I thought I found a solution, but it didn't end up meeting all of my needs. After much desperation I stumbled across Trunk, and it does EXACTLY what I was looking for. Not only that its sync is super fast and maintains my inventory levels across multiple channels almost instantly when an adjustment is made.

I just launched my Shopify store this week. With the help of Trunk Inventory I was able to sync my Etsy inventory with my Shopify store. I did have a question which I submitted to trunk and they immediately got back to me and gave me instructions for what I needed. Trunk is a game changer. I love it. Thank you Trunk.

What can I say, I am a fan! We keep a small inventory and so Trunks ability to keep all our inventory across the 4 different platforms correct and in real-time is key. Every other software needed at least 15 min. Additionally, they are the only ones who do bundling and kitting. Such an overlooked but priceless feature.
