Trip margin, the same day.
They source tomato and chili for industrial plants. The system costs every trip against the purchase order, separates estimated from real margin and explains the gap by shrinkage or quality penalty — money that used to leak with no one measuring it.
The problem
Each trip's margin surfaced weeks later, when nothing could be fixed. Accounts with suppliers and financed carriers lived in notebooks, and advances went out with no proof attached. Reconciling the two bank accounts took days of manual work.
What was built
Per-trip costing that compares estimated against actual margin as soon as the scale ticket is entered. Running accounts per supplier and per carrier. Advances that require proof before they close. Bank reconciliation by reference against both accounts — and all of it working offline: capture happens in the field and syncs on return.
Status
Every phase delivered and tested; the client runs it. CFDI stamping was dropped by their decision, not for scope.
