Proof Of Delivery 

The ABM Proof of Delivery mobile app was designed to provide a simple application that mobile delivery people can use to capture a customer's confirmation that they have received their delivery, similar to a courier. The app uses a barcode scanning component to allow an invoice to be quickly selected. This assumes that the driver will have a printed copy of the invoice with the invoice reference (accountingref) printed as a barcode so that it can be scanned. A "delivery sheet" of the invoices on the delivery
run with scannable barcodes would also work.
