Built around plumbers' jobs

Callouts invoiced in seconds

Just back from an emergency job? One message and the invoice is written, emailed and recorded before you've left the drive.

Gas Safe & job refs kept

Drop the boiler model, the Gas Safe notification reference or a quick note and it's stored against the job for your records.

Late payers chased for you

Amy sends the reminder with your bank details and a pay link, so you're not the one having the awkward conversation.

We're not accounting software. We're the layer before it.

Xero and QuickBooks are accounting software — the ledger your accountant works in. TradesOffice is the bit before that: it captures your invoices, expenses and mileage as you work, so there's something clean to hand over. Plenty of plumbers use TradesOffice and still have an accountant — we just make sure the records are already done. No app to download, no new number, £12.99 + VAT a month.

Common questions

Can I invoice emergency callouts quickly?

Yes — that's the point. One WhatsApp message and Amy writes the invoice, emails the customer and stores the record in about 60 seconds, even straight after the job.

Can I keep Gas Safe or boiler references on a job?

Yes. Send Amy a note with the boiler model or Gas Safe reference and it is saved against that job for your records.

Do I need a new number or an app?

No. You use your existing WhatsApp and your existing number. Nothing to download, nothing new to carry.

Is this accounting software?

No. TradesOffice is the layer before accounting — it captures your invoices, expenses and mileage as you work, so your accountant has clean records to file from.
