Trade paperwork that saves money
- Log every business journey: mileage at HMRC rates often beats claiming fuel.
- Keep materials receipts, including small ones from merchants.
- Domestic customers aren't covered by the late payment law, so agree payment on completion up front.

Questions
Can customers pay on the spot?
Yes. Every invoice has a pay link with card, Apple Pay, Google Pay and Pay by Bank.
Does it work without signal?
You need a connection to send invoices. If it drops, Fenquist tells you and retries when you're back online.
