Vorker handles the office work of truck and bus workshops: job confirmations, parts invoices booked, invoices to hauliers and inspection reminders. You approve everything.

No. Every confirmation, invoice, text and reminder is prepared and then waits for you. You can read it, edit it, reject it, or approve it and schedule it to go out later. Nothing sensitive happens on its own.
That is the size it is built for. In a three-person workshop the best mechanic is also the one doing invoices at nine at night. Vorker is made for businesses of one to ten people, not for dealer chains with a service desk.
Every vehicle it has seen in a booking, a job card or an invoice gets a due date. When an inspection approaches, Vorker drafts the booking text to the haulier on its own and holds it for your approval. No rig goes overdue quietly.
Photograph them and Vorker matches the supplier, works out the accounting lines including VAT, and attaches the image to the entry. It learns how you book each supplier, so the next invoice from the same factor is handled the same way.
It drafts from your own rates and what similar jobs have cost before, and it gets closer the more you use it. Treat the first draft as a starting point you adjust. That is still much faster than building every invoice from scratch.
No. You type or say what you need, the way you would tell someone at the parts counter, and Vorker works inside the tools you already have: your email, your calendar, your accounting.
