Aliança Log Uzz.Ai Case Study
Real-time digital proof of delivery
A custom-built system that digitizes the entire last-mile delivery operation: it builds the load manifest, tracks drivers in the field and delivers proof of delivery to the end customer in real time — even with a weak signal.
The problem
A delivery operation in Brazil's Serra Gaúcha region running at its limit, relying on paper and on getting lucky with cell signal.
Paper delivery receipts
Every delivery signed on paper, with no real-time record of where the cargo is.
Spotty signal
Operating in the Serra Gaúcha mountains without reliable coverage — spreadsheets and WhatsApp don't hold up offline.
Operating at scale
2,000+ deliveries a month riding on the same manual process, with zero room for error.
The solution: Aliança Log
It digitizes the entire proof-of-delivery cycle — from building the load manifest to a receipt the end customer can see in real time.
3 roles, one app
Management, drivers and end customers — each one sees only what they need.
Truly offline-first
Drivers log deliveries with no signal; everything syncs automatically when the connection comes back.
Load manifests in seconds
Barcode scanning with the phone camera or direct import from Excel/electronic invoices (NF-e).
Complete digital proof of delivery
Photo, signature and geolocation on every delivery — real proof, not lost paperwork.
Truly real-time
The management dashboard updates in under 3 seconds after a delivery is logged in the field.

How it works
From load manifest to proof of delivery, without depending on signal.
Import the load manifest
Excel/NF-e or camera scanning — rich invoice data is matched with what was scanned.
The driver hits the road
The app works 100% offline. A weak signal on the highway never stalls the operation.
It becomes a digital receipt
Photo, signature and GPS location captured at the exact moment of delivery.
Syncs on its own
When the signal returns, the queue of receipts uploads automatically — no record gets lost.
The customer follows along
The end-customer portal shows status and proof of delivery as soon as the delivery happens.
This is the kind of system we build when your business bottleneck doesn't fit an off-the-shelf tool: we map the real problem, design the flow and deliver software that works even where signal and internet let you down.
