Vorker handles the admin around your truck: event quotes, arrival confirmations, the day’s takings booked, invoices and permit renewals. You approve everything.

No. Every quote, confirmation, invoice and application is prepared and then waits for you. You can read it, edit it, reject it, or approve it. Nothing reaches a client or the council on its own.
That is the size it is built for. On a truck the owner is also the booking desk, the bookkeeper and the one filling in permit forms at midnight. Vorker is made for businesses of one to ten people.
It drafts from your own per-head prices and how you quoted similar events before, and it gets closer the more you use it. Treat the first draft as a starting point you adjust before approving.
You tell Vorker your permits and their dates once, or forward the paperwork. A month before one expires it drafts the reminder and fills in the renewal application, and the draft waits for your approval like everything else.
Photograph the till report and the receipts and Vorker books them with the VAT on its own line and the images attached. Matching every card transaction automatically needs the POS integration, which is coming; until it is live Vorker will not pretend to do it.
No. You talk to Vorker the way you would text the person riding shotgun, and it works inside the tools you already have: your email, your calendar, your accounting. Quotes and invoices arrive as ordinary PDFs.
