The Royal Borough of Windsor and Maidenhead (RBWM) is committed to ensuring prompt payments to our suppliers.
To streamline our financial processes and meet statutory 30-day payment targets, we are officially introducing a strict "No Purchase Order, No Pay” policy, effective from Wednesday 1 April 2026.
What this means for our suppliers:
From Wednesday 1 April 2026, any invoice submitted for goods, services, or works must quote a valid RBWM-issued Purchase Order (PO) number.
- No PO = No Payment: Invoices received after this date without a valid PO number will be rejected and returned to you unpaid.
- The "Bill To": Name and address on your invoice must map exactly to the Royal Borough of Windsor and Maidenhead Entity named on the PO.
- Purchase Order number: must be clearly visible in the header section of your invoice.
- Submission of Invoice: Each invoice must be sent as a single PDF attachment directly to the Council Representative who placed the order or to Finance.Supplierinvoices@RBWM.gov.uk.
- Attachment Mapping: If you include supporting documents (like delivery notes), they must be part of the same PDF file, following the invoice as subsequent pages.
If you have three invoices, you must send three separate PDF files (though they can often be in one email). - Payment Timeline: The 30-day payment clock will only commence once a valid and compliant invoice is received.
- Escalation Process: If a compliant and undisputed invoice remains unpaid after 30 days, please contact the Financial Control Team at Financial.Control@RBWM.gov.uk for resolution.
We appreciate your cooperation in helping us transition to this more efficient “No PO, No Pay" system.
