Riutbag By Riut
I'm moving over to Shopify from Squarespace. After a long search, I'm so glad I've found this app. I'm using it to automatically send my daily orders to a third party fulfilment shipper via emailed CSV file. I can rearrange the columns to suit me, rename them and edit the file name.
Make sure you know the exact column headings your fulfilment company's system needs so you can match them up in this app. Spend about 30 mins - 1 hour setting it up and then you can start to download and export test files.
I'm still setting up and have been in touch for customer support. Really quick, clear and helpful responses have come every time. Definitely recommend this app.
