Send an invoice

All invoices sent to us must include:

• a valid purchase order number
• your supplier ID number, which you can find on your purchase order
• an invoice date
• an invoice number
• a total amount payable, plus VAT if applicable
• the word ‘invoice’ clearly visible
• your full name and address

If you have multiple purchase orders, you must use separate invoices. You must send each one to us as a separate file.

You can download a supplier guide and invoice templates. 

Where to send your invoice

To have your invoice processed as quickly as possible, email invoices@lincolnshire.gov.uk.

Your email must have:

• the word ‘Invoice’ in the subject field
• the invoice attached as a PDF
• separate invoices each uniquely named, if applicable

If you do not include a valid purchase order number, we will return the invoice to you. This will likely delay the payment.

We only accept handwritten invoices if agreed in advance.
