Work through the go-live checklist in the Complete Guide: company details and logo, every depot with a position on the map, attendance rules, pay settings and the company bank account, public holidays, the sales tax rate, and the delivery update emails. Then add staff, drivers with pay, tax and bank details, vehicles, customers and rate cards.
Finish with a test run: book a test job to your own address, print its label, allocate it, have a driver clock in, pick up and deliver it, check the proof of delivery and the emails, clock out, then create the invoice from Ready to invoice and delete the draft.
