Your shop details. You add and manage your products yourself in Square — I only need to know how customers get them. (Already did the Square steps above? Skip straight to the fields — you're all set.)
ADDING YOUR PRODUCTS (do this in Square, on your own time): In your Square Dashboard, go to Items → create a new item → add the name, price, description, and photos, and set how it's fulfilled (ship or pickup). Save, and it appears in your store. Got a lot of products? Square lets you upload them all at once with a spreadsheet: Items → Import/Export → download their template, fill it in, upload it back. Full walkthroughs are in Square's help center if you ever get stuck.
