Trazzo · Proof of delivery

Proof of delivery softwarewith photo, signature and GPS at every stop

Every stop closes with evidence: a photo of the goods, the recipient's signature, the location and the exact time. Trazzo reconciles what was dispatched with what was delivered and releases the invoice the same day, without waiting for the paper delivery note to come back.

The short answer

How do you verify deliveries without paper delivery notes?

You verify deliveries without paper when every stop closes with a digital record that brings together the photo, the electronic signature, the GPS location and the exact time, tied to the order and the delivery note. At the end of the day, the system matches what was dispatched, what was delivered and what came back, and surfaces only the differences. That way the invoice goes out the same day and every claim has evidence behind it.

Trazzo is Vantegrate's AI agent for the last mile, and it runs those checks from the driver app. This guide shows what to capture at every delivery, what to do when one goes wrong and which metrics to track. The proof of delivery glossary entry covers what a proof of delivery is and what it is for. Delivery verification is one of the functions of the AI agents for business that Vantegrate covers.

The evidence

What every delivery records and how it helps with a claim

A delivery does not close by tapping "delivered". The driver fills in a record with several fields, and each one answers a different question when someone disputes the delivery weeks later. The definition of proof of delivery (POD) lives in the glossary; this is its operational version:

FieldWhat it storesHow it helps with a claim
PhotoThe unloaded goods, at the delivery pointShows the condition the goods arrived in
Electronic signatureThe recipient's signature, on the phone screenProves that someone accepted the delivery
GPS locationThe coordinates at the moment the stop closedProves where the goods were unloaded
Exact timeThe time of the actual event, even if the phone syncs laterProves when it was delivered and whether it fell inside the delivery window
Received byThe name and, if your operation requires it, an ID numberIdentifies the person who signed
Delivery note numberThe delivery note or dispatch note your system issuesTies the evidence to the commercial document
Quantity per lineWhat was received on each line of the orderLets you accept or dispute a partial delivery
Customer stamp or documentA photo of the stamp or the receiving slip, if the customer uses oneAdds the proof the customer itself asks for

Even with no signal: the app works offline. The route downloads at the start of the day and the evidence uploads on its own when the signal comes back, with the time of the actual event and not the time of the sync.

When it goes wrong

Failed deliveries: reason, action and who gets notified

The delivery that goes wrong is where the margin goes. In Trazzo the exception is not free text: the driver picks a standardized reason code and attaches the photo that backs it up. Each reason triggers a different action, and at month end you can see which one keeps repeating in the failed delivery rate.

In every case, the rest of the route sheet is recalculated live: the time freed up is reassigned and the control tower sees the delay before the customer calls.

ReasonWhat Trazzo doesWho gets notified
Customer not presentOffers to reschedule in the same WhatsApp chat, and the stop goes back onto the route for the right dayThe customer
Invalid or incomplete addressSends the address to the exceptions queue, so it gets fixed only onceOperations
Damaged goodsRecords the photo and opens the return in the reverse logistics workflowThe warehouse
Rejected over delivery note or priceRecords the commercial reason and leaves the order openSales or accounts, not the warehouse
Outside receiving hours or no spaceRecords the attempt with its photo and leaves the stop to be rescheduledOperations and the customer
Partial deliveryRecords the lines received and the ones going back on the truck; the order stays with a pending balanceBack office

The reasons and the action for each one are adjusted to your operation in the settings.

End of day

End-of-day reconciliation: dispatched, delivered and returned

When the workday closes, the question no GPS answers shows up: this went out, that was delivered, and where is the difference. Trazzo matches three sets: what was loaded onto the vehicle according to the dispatch order, what was confirmed in each proof of delivery and what came back to the warehouse with its reason. Differences show up by line, not by trip:

Order lineDispatchedDeliveredReturnedResult
Mineral water 1.5 L (6-pack)651Returned with photo: damaged goods
Soda 2.25 L (6-pack)10100Closed
Juice 1 L (case of 12)430Open discrepancy: one unexplained case, with owner and time

Illustrative example of an order from a beverage distributor.

Back in your system: the order is marked delivered, partial or rejected, the delivered goods come off the vehicle's inventory and the invoice is released with the proof attached. The back office closes the day with a short list of exceptions, not with a stack of delivery notes to type in.

Metrics

Delivery metrics and how to calculate them

With every stop recorded, the metrics come out of the system and not out of a spreadsheet put together at month end. These are the ones operations and the back office track, with their formula.

To estimate what each failed delivery costs you, there is the last-mile cost calculator.

MetricHow it is calculatedWhat it tells you
OTIFOrders delivered on time and in full ÷ orders deliveredWhether you deliver what you promised, on time and in the right quantity
Failed delivery rateFailed deliveries ÷ attempted deliveriesHow many second trips your operation pays for
First-attempt delivery rateDeliveries completed on the first visit ÷ attempted deliveriesThe flip side of the previous one, the one used as a target
Open discrepanciesLines with an unresolved difference at the end of the dayHow much unexplained shortage the operation carries
Unloading timeTime the stop closed minus time of arrivalWhich customers hold up the truck and throw the route off
Integrations and limits

What it integrates with and what it does not do

Trazzo connects to the system where your orders already live: Salesforce, SAP, Oracle and Microsoft Dynamics through a direct connector, and any other system through API and webhooks. For a limited pilot you can also start with a file. The status of each delivery, its reason and the link to the evidence are written back to the original order.

And it is worth knowing what it does not do:

  • It is not a TMS: it does not manage long-haul transport, it does not tender freight and it does not settle trips with carriers.
  • It is not a WMS: it does not manage locations or picking inside the warehouse; it takes the order already prepared.
  • It does not issue delivery notes: or tax documents either. Your system issues the delivery note, and Trazzo ties it to the delivery.
  • It does not replace satellite tracking: it works alongside whatever you already have, because the position the app uses comes from the driver's phone.
How it works

Rollout in 4 to 8 weeks

The timeline holds when orders already come out of your system clean. What stretches it the most is the addresses: a customer master file with incomplete addresses has to be cleaned up before the first route.

1

Assessment

Weeks 1 and 2: we map your routes, vehicles, constraints and delivery points, and connect your ERP.

2

Configuration

Weeks 3 and 4: we configure the routing engine, the driver app and the exception reasons, and test with real routes.

3

Go-live

Weeks 5 to 8: phased go-live, driver training and in-field support during the first routes.

Key data

What large buyers demand

When a large customer measures OTIF, every delivery without proof can end in a fine. Public industry data, not Trazzo results.

Frequently asked questions

Frequently asked questions about proof of delivery software

What an operations or back-office manager asks before giving up the paper delivery note.

Does the digital record replace the delivery note?

Not where regulations require one: it works alongside it and digitizes it. Your system still issues the delivery note, and Trazzo attaches the photo, the signature, the location and the time of the delivery to that number. What changes is that you no longer have to wait for the signed paper to release the invoice.

Does it work if the driver loses signal?

Yes. The route sheet and the data for each stop download at the start of the day, and the driver records deliveries in a basement or a rural area with no coverage. Photos, signatures and coordinates upload on their own when the signal returns, with the actual time of the event. What does need a connection is live re-optimization and notifying the customer.

Does it work if I deliver with contract drivers?

Yes. Each contract driver or owner-operator is set up as a unit with its capacity and zone, uses the same app and leaves the same proof of delivery, so the evidence does not depend on who is driving. The only thing to agree on up front is that the driver uses the app. What a mixed-fleet operation looks like is covered in Trazzo for Ground Logistics.

Does the evidence back me up if the customer disputes the delivery?

That is what it is for. Every stop closes with a photo, an electronic signature, the location and the exact time, plus the name of the person who received it and the delivery note number. Together, that shows where and when the goods were unloaded, and it is much harder to dispute than a piece of paper with an illegible signature.

How much does Trazzo cost?

Trazzo is priced in two parts: an initial implementation, quoted based on delivery volume, the number of vehicles and the integrations, and a monthly subscription with AI credits that you can expand as your volume grows. There is no lock-in. For your case, request a quote.
