You might want to re-think integrating with Square. It is an expensive alliance.
Etsy - once synced - acts as if every item you ever sell on square using that account was an etsy item. And as such Etsy will bill you a listing fee for every item sold.
If your square shop is just echoing exactly what you have on your etsy shop, then a listing sold on etsy or sold on square are treated the same as far as a relisting fee is concerned. Which isn't an issue.
The problem is for those items for which you use square as the payment processor -- say selling at craft shows -- where the item you're selling was never listed on Etsy. Etsy doesn't care, and square notifies etsy of the sale and Etsy bills you a listing fee for that item, even though it was never on the Etsy site.
Do this for 1500 in-person-but-never-on-etsy items over the course of the selling season and you've paid etsy $300 US for the 'free integration' with square.
My sister did this -- for 5 minutes until we saw this rip-off.
Yes it's convenient for stock levels to marry between square and Esty, but when you try to use your account for anything else, Etsy still wants a piece of the action.
