Customer accepted your quote? Convert it into a professional invoice in 60 seconds. Add an invoice number, due date, and bank details — then download the PDF.
Add what a quote doesn't have — your business details, bank details, and invoice fields.
Once your customer has accepted your quote — whether by email, text, or a verbal agreement — you should convert it into a formal invoice. The invoice is the document that requests payment and starts the clock on your payment terms. The sooner you invoice after the work is done, the sooner you get paid.
A quote is an estimate; an invoice is a request for payment. The key additions are: a unique invoice number, a due date, your bank or payment details, and legal standing. A quote has no obligation to pay — an invoice does. You may also update the date to reflect when the work was completed.
If extra work was agreed during the job, update the line items on your invoice to reflect the actual work done. It is good practice to note the original quote reference and explain any differences. Communicate changes to your customer before invoicing to avoid disputes.
Yes. HMRC requires every invoice to have a unique, sequential number. This tool auto-generates one for you, but you can edit it to match your own numbering system. Never reuse an invoice number — it makes your records harder to audit and could cause issues with tax returns.
With WOPA, there's no form to fill. Just message "invoice the bathroom job for Sarah" and WOPA does the rest — from quote details you've already shared.
