What Happens When a WhatsApp Order Asks for Something You Don't Have
A shop's WhatsApp catalog is only as useful as it is honest. If it still offers an item that sold out yesterday, every customer who orders it is walking into a disappointment the shop could have avoided. The fix isn't clever wording, it's actually tracking stock.
Real stock, not a static list
Every item has a real quantity on hand, a minimum stock threshold, pricing, tax rate, and an expiry date where relevant, kept current rather than entered once and forgotten. A shop can bulk-import its whole inventory from a spreadsheet, with the system suggesting which columns mean what, instead of retyping hundreds of items by hand.
That threshold is what some tools call low-stock alerts, except here it isn't a separate notification an owner has to go check. It's the same number the WhatsApp bot itself reads before deciding whether an item can be ordered at all.
An out-of-stock item is simply invisible to the matcher
When someone orders over WhatsApp, the bot only ever matches against items that currently have stock above zero. An item that's run out isn't offered and then apologized for, it's excluded from what the bot can even recognize in the first place, which is a quieter and more honest way to handle it than pretending to check and coming back empty.
When nothing matches, a human answers, not a guess
If a customer asks for something the bot can't confidently match, whether it's genuinely out of stock, misspelled, or just not something the shop carries, it doesn't invent an answer. It tells the customer it'll check and get back to them shortly, lets them keep shopping or check out the rest of their order in the meantime, and sends the exact question straight to the shop's dashboard for a staff member to answer in their own words.
This is sometimes called product substitution, offering a close match instead of just cancelling the item, and it's exactly how ZiroWait lets a staff member handle an out-of-stock item inside a WhatsApp order, rather than losing the sale outright.
