How to invoice the University

Our services are currently only available by email/phone. Please do not post invoices as we cannot process paper at this time. Instead, email them to

Purchase order policy

All invoices submitted for payment must clearly quote a University of Bristol Purchase Order number. Our Purchase Order number consists of eight numbers beginning with an eight (e.g. 81234567). Purchase Orders from our Estates Services Division consists of six numbers, a dot and then two numbers (e.g. 123456.78).

If you do not have a Purchase Order, please do not proceed with the order, please contact the university department making the purchase and ask them to provide one. Failure to quote a Purchase Order number on your sales invoice will result in the invoice being rejected no payment will be made.

To avoid your payment being delayed please ensure you are given a Purchase Order number when accepting an order from the University of Bristol.

Electronic invoicing

All supplier invoices should be sent to These should be sent as a PDF as we cannot process invoices submitted in Word (.docx) or Excel (.xlsx) format. 

Please note: There are a number of suppliers who send both electronic and paper copies of invoices. This leads to delays in payment as duplicate invoices require manual processing once identified. We therefore request suppliers no longer send paper copies and that PDF invoices are emailed to

If you are contacting us to follow up on late payment, please do not resend the invoice unless this is specifically requested by one of the team.

Our standard payment terms are 30 days from the date of invoice.
