Thanks for the pointer. I've been looking at all of those this morning, and so far haven't found any that talk about receiving inventory. I suspect they're all built for a more robust solution where inventory is maintained based on purchase orders and then imported to Square. What I need is to execute individual stock actions on a per-case basis.
My use case is a snack bar at a school, and we may come in on Monday morning and see that they sold out of M&Ms, Fritos and Coke at the basketball game over the weekend. We go to the Costco down the street and buy a couple cases of each. Now I need to add those cases to my inventory. I'm not going to run an export, update in the spreadsheet, and reimport just to get those few items. But doing each of them by hand is error-prone.
My perfect solution is to go to the Items tab, tap a "Receive inventory" button, and get a screen that looks like a sale. I scan multiple cases, and when I complete the transactions it executes stock actions to add the correct quantity of each.
If I could find the correct API for this, it's a couple of days coding to make it happen. Even better if I could leverage the existing sales UI.
