It's now easier than ever to log that a payment has been made from the mobile app while processing deliveries. Simply use the new "Log payment" button on the delivery screen (making sure you're using the latest version of our app - v2.4.0 or higher). You'll also be able to see the amount due at a glance.

Thanks to everyone who voted for the Cash on delivery shown in delivery app & record payment as taken from the app feature request and pushed this up the priority list.
