The website might keep selling after the counter sells the last one.
Your till and bookings removed a way to check inventory transfers on 14 July. If your stock routine relies on that check, it will have stopped updating when something sells at the counter.
When it happened: today, 14 July 2026 What it costs you: A refund, an apology, and a review. In December it is worse because the counter is busy and nobody is watching the numbers. How late you would normally find out: A few days, when the second customer complains.
What to do: Forward this to Priya to check whether the routine uses the removed transfer check, and if it does, to rebuild it with what your till and bookings offers now.

Priya,
FACT: Square removed endpoint GET /v2/inventory/transfers/{transfer_id} on 14 July 2026.
INFERENCE: The stock-between-counter-and-website routine is mapped to this endpoint with high confidence. If the routine uses this call to verify or track inventory transfers between locations, it will have broken.
Check whether the routine depends on GET /v2/inventory/transfers/{transfer_id}.
If it does, find the current Square method for tracking inventory movement between the counter and website stock, and update the integration.
