You can create a custom payment method called "Afterpay".
Go to Admin, then into the Lists tab. Drop down the Select Lists menu and choose Payment Methods. Click New.
On the right side panel, enter Afterpay into the name field. Ensure that Show On POS is ticked, and click Save.
The Afterpay payment method will be added.
Now when a client pays using Afterpay, simply add them to the sale as you normally would, and instead of choosing Cash, Credit, Eftpos etc, choose Afterpay from the drop-down menu and Finish Sale.
