Why does the website say in stock when the shelf is empty?
Shops that sell in store and online hold back a buffer of stock from the website count to avoid overselling, which deliberately makes sellable stock unsellable, because the two counts only sync on a schedule instead of the moment the last unit goes.
Who has it: Independent retailers selling from one or more physical locations and an online store at the same time.

Scoring breakdown
Existing players
- Point of sale systems with a built-in web store · Share one stock number, and per the thread tend to sync at company level on a schedule rather than per location on the last unit.
- Multichannel inventory apps · Push counts between channels, and still leave the owner guessing how big a safety buffer has to be.
- A manual safety buffer · The common fix, which trades overselling for stock that sits on the shelf and never sells online.
What they are missing
Per-location stock that updates the website the moment the last few units sell, with a buffer that shrinks or grows from each product's real sales speed instead of one fixed number held back everywhere.
