Who builds it

Built by a tradesman, not a software company

TradeOS is built by a Gas Safe registered engineer who runs a real heating business — the quotes, certs and invoices in this app are the ones he sends his own customers. If it doesn't survive a day on the tools, it doesn't ship.

How it works

From job booked to invoice sent, in three moves

The certificate and the invoice both start from the job, so the customer's details come with them.

Certificates & paperwork

Certificates issued from the job, not from a stack of forms

Gas, electrical and service paperwork lives with the job it belongs to. Fill it in on site, keep the photos and notes from the visit alongside, and send it to the customer when it's done.

  • Certificates tied to the job and the customer
  • Photos and observations kept with the record
  • Sent to the customer from the app
  • Compliance where your trade needs it — not where it doesn't
