Invoice and Payment Timescales

This article provides information on the timescales associated with invoices and payments for services commissioned via Primary Eyecare Services (PES).


Activity completed by your practice for a particular service in a month will be compiled and an invoice generated in the second week after month end. With the overarching invoice from Primary Eyecare Services (PES) and associated supporting data submitted to commissioners thereafter. 

This process requires no action by practices as is carried out by PES with the support of Opera and other associated systems. 


You must close/complete (and appear marked Green on Opera) an episode in order for it be charged. If you need to close an open episode you can follow the instructional guide linked here to enable you to do so. If you need support when closing a patient episode, please contact is for support via the help function on Opera.

Please remember that episodes should be completed and closed on Opera ideally on the same day of the patient interaction took place (as a minimum for those being referred) but within 2 working days as a standard minimum. This is important for patient safety, communications with GP, contractual requirements etc. - including invoicing and payment!      

Raising issues with your invoices

All finance queries should be raised and will be adjusted on your next invoice. We expect that there will be few of these.

All queries should be raised via the blue bubble on Opera or emailing  Please provide your practice name, ODS code and OPR numbers for episodes that you need assistance with.


The commissioner invoice is due for payment to PES at 30 days after submission and disbursement to practices will take place within 7-10 working days to optical practices. This will be paid to the bank account you uploaded details for onto Opera as part of the onboarding process. 


An invoice becomes overdue for payment to PES approximately 6 weeks after month end and to practices 8 weeks after month end. 

It is expected that regular monthly payments should be made to practices albeit they will be for 1-2 months in arrears due to the above process with NHS commissioners. 

Inevitably there will be cases where some are delayed payments from commissioners and thus the above process is delayed and extended. Please note there are often some delays in the early stages of a new service prior to regularisation of payments.  

In all cases PES will actively chase commissioners for overdue monies and pay practices as promptly as possible.   


Should you need general finance support please either go to and use the help bubble to raise a query or email 

When raising queries via this method please include your practice name, ODS code and area you are based in to enable us to identify which practice the query relates to.
