Invoice Number not showing

Dear All,
While making a payment and Generating Invoice, the Receipt does not show the Invoice Number. Its blank. Do I need to enable it somwhere?.
In Admin-Config-Billing the “Enable Batch Payment” is enabled.
Any help appreciated.

hi @levijustus , currently invoice reference numbers are only enabled if the emr is configured to be running an inhouse pharmacy.

then you can go to Admin->Users and select an irnpool to pull from, the invoice ref nos can be configured in Admin->Forms->Lists->Invoice Reference Numbers

Dear Steve,
Thanks for your Guidance.
I am having some issues after enabling the inventory feature. I have raised another thread to get help on that. I will return back to this thread after resolving the other issue.
