Vorker runs month end across your client roster: storage invoices from pallet counts, stock reports attached, inbounds booked and low-stock alerts drafted. You approve everything.

No. The invoice run is drafted and then waits for you. You can open any invoice, adjust any line, hold one client back, or approve the run as a whole. Nothing goes out until you press.
That is the size it is built for. In a three-person warehouse the one doing the invoicing is also the one on the forklift, so month end happens at night. Vorker is made for companies of one to ten people, not for sites with an admin office.
From your own records. Tell Vorker the movements as they happen, or forward the delivery notes and dispatch confirmations you already handle, and it keeps a running count per client. The invoice run is built from those counts.
No. Vorker sits alongside whatever you use and does the work around it: the invoice run, the stock reports, the client emails, the supplier bookkeeping. Nothing gets migrated.
You set a floor per item, or let Vorker suggest one from the dispatch pace. When a line crosses it, the warning email to the client is drafted and waits for your approval, like everything else.
No. You talk to Vorker the way you would tell someone at the desk, and it works inside the tools you already have: your email, your sheets, your accounting. The invoices and reports arrive as ordinary PDFs.
