Using Purchase Credits
When using purchase credits, we recommend creating them from a purchase invoice.
To do this, open the purchase invoice you want to put the credit on.
Go to Activity > Purchase Credits > New and select one of the options.
Double-click on the new credit and fill in the details and click ‘Save‘. You can post it to Sage or Xero by going to Tools > Post to Accounts.
Now, go to Purchases > Purchase Invoices/Credits to see all credits highlighted in red.
