Vorker handles the month-end paperwork of small haulage firms: run logs, cab receipts booked, subcontractor invoices reconciled and the monthly invoice drafted. You approve everything.

No. Every invoice, reminder and email 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 two-truck firm the person invoicing is also the one driving, so the paperwork happens at the kitchen table. Vorker is made for companies of one to ten people, not for hauliers with a transport office.
From your own runs. Tell Vorker the loads as you tip them, or forward the weighbridge and delivery notes you already get, and it keeps a clean log per customer and site. The monthly invoice attaches it automatically.
It matches every line against your own delivery notes and flags what does not agree: a run invoiced twice, a run with no note on file. You decide what to do with the flagged lines. Nothing is paid or disputed without you.
Photograph them and Vorker matches the supplier, books the entry with the VAT on its own line and attaches the image. It learns how you book each one, so the next fuel receipt from the same station is handled the same way.
No. You talk to Vorker the way you would text someone in the office, and it works inside the tools you already have: your email, your calendar, your accounting. The invoices arrive as ordinary PDFs.
