Lark & Key

I wanted more information and customization than the Shopify invoice provided. I bought the app and by mistake bought it a second time. I also realized I still wanted a bit more detail than the app allowed. I contacted Bjorn, replying to his 'Thank you for your purchase email' - and he was very quick to reply. Not only did he refund the first purchase, he provided custom code to make the invoice exactly what I needed.
