Vorker turns scrawled needs lists into confirmed orders, flags substitutions, invoices on delivery and drafts replenishment offers. For teams of 1-5. You approve everything.

No. Every confirmation, invoice and replenishment offer is drafted and then waits for you. A confirmation is a promise about stock and dates, which is exactly why it is held until you press the button.
Yes. It reads the photo or the email, matches every line to your catalogue and the customer’s history, and flags anything it is unsure about instead of guessing. You check the confirmation before it goes anywhere.
Vorker finds the closest equivalent in your catalogue and flags the substitution on the confirmation, visibly, so the customer sees it before the van runs. It never swaps silently, because a silent swap is how you lose a factory.
Vorker learns each customer’s consumption rate from your order history. When the pattern says a consumable runs out soon, it drafts the offer with the usual quantities and waits for your approval. It never sends on its own.
That is the size it is built for. There is no office team, so the confirmations and invoices happen after the counter closes. Vorker is the office you never hired, minus the desk.
No. You type or say it, the way you would tell someone at the counter, and it works inside what you already have: your inbox, your accounting, your phone. The confirmations and invoices arrive as ordinary PDFs.
