Questions
How do I save the invoice as a PDF?
Press "Print or save as PDF" and choose "Save as PDF" as the printer. Only the invoice prints, not the rest of the page.
Should I number invoices in order?
Yes. HMRC expects each invoice to have a unique number, and a simple sequence (1001, 1002…) makes your records easy to follow.
What payment terms should I use?
Short ones. Many tradespeople ask for payment on completion or within 7 to 14 days for homeowners, and 30 days for business customers.
What if the customer doesn't pay?
Send polite reminders on a schedule. Our payment reminder templates give you four, from friendly to final notice.
