Step by step

  1. Open Invoices, choose the create action and select the correct customer and job.
  2. Confirm the recipient, currency, invoice date and default due date.
  3. Choose the relevant quoted lines, approved variations, costs, labour or intentional invoice-only lines.
  4. Save the draft and review every line description, quantity, unit value, tax and total.
  5. Open the rendered document and confirm number, business identity, recipient and payment information.
  6. Choose Save and approve or the supported issue action only when the draft is complete, then follow delivery and sync state.

Good practice

Keep the invoice as a draft while commercial sources are still changing. Issuing is a controlled financial action, not a formatting preview.

When you are finishedThe issued invoice has the intended recipient, scope, due date, tax, amount and source traceability.

Before you begin

  • The customer and job are correct and the billable scope has been approved.
  • Numbering, payment and tax defaults have been tested.
