Merlin: Redesigned Driver Reconciliation in FMCG Distribution

Background

In FMCG distribution, a driver delivers to a list of shops and returns to the warehouse at day's end. The Warehouse Operator then verifies all payments and returns against each bill. It's called Driver Reconciliation. Done manually, bill by bill, at the end of the day, it was slow and inefficient. The challenge: how can I redesign the Driver Reconciliation flow to reduce the time it takes and make it more efficient?
