How do you quote and invoice from a job site?
From your phone, create a quote with your labour and materials lines, apply the correct VAT rate (10% for renovation, 20% for new build) and send it for electronic signature. As soon as the client signs, you can request a deposit to start the work. On completion, the balance invoice is generated in one click and deducts the deposit. Every invoice embeds the Factur-X format and is automatically sent to the Public Invoicing Portal. The client pays by card via the QR code — handy when they have no chequebook on site. You track in real time what is paid and what remains due.
