For electricians, plumbers, HVAC, fire & security and gas. Plan the round, send each engineer the customer's address and the right form, and the job comes back signed off from the phone, ready to invoice — never re-typed at a desk in the evening.
The on-site forms are built for trade work, not generic checklists — the layout a trade engineer recognises. Filled in on the phone, signed, and stored against the customer's record for next time. We spent a real day on the BS 7671 EICR template, because the people using it would notice if we hadn't.
Office staff get the full platform at £39. Engineers who never open a laptop get a £12 mobile seat — job list, forms, sign-off and time entry, nothing more. Add as many as you have vans.
