Automate freight audit and proof of delivery
Unstract reads each carrier freight invoice with its signed proof of delivery, audits the charges against the rate confirmation and the bill of lading, and approves the clean ones in your TMS or ERP.
Trusted by logistics and supply chain teams around the globe
Freight bills arrive faster than anyone can audit them
The agreed rate sits on a rate confirmation, the weight on the bill of lading and the delivery on a POD a driver photographed at the dock. The carrier's invoice comes separately, and someone has to put all four side by side before it gets paid.
Charges keyed by hand from each carrier's own invoice layout
A driver's photo of a POD with the exception written in the margin
A billed weight heavier than the bill of lading
An invoice waiting two weeks for a POD someone can read
The same PRO number billed twice and paid twice
An unchecked accessorial, a heavier billed weight or a load paid twice goes straight out of the freight budget, and a short delivery found after payment is much harder to claim.
Unstract reads every freight bill and its POD, runs the freight bill audit against your contract rates, the rate confirmation and the BOL, and approves the invoices that pass. An auditor sees only the charges that don't.
From the carrier's invoice to your TMS or ERP, without the keying
Five steps, run on their own for every freight invoice. Parsing by LLMWhisperer, extraction by Document Studio, the whole run by Flow.
Pick up invoices and PODs wherever carriers send them
Carrier freight invoices come in as PDFs by email and as EDI 210s. Signed PODs and delivery receipts come from driver photos and carrier portals. Each invoice is paired with its POD and BOL by PRO number, so one record holds everything the audit needs.
The audit can't start on half a file, so the pairing happens the moment both halves exist.
Read every invoice and POD, then pull the charges and the signature
LLMWhisperer reads each invoice and POD as text with the layout kept, so a creased delivery receipt photographed in a cab reads as well as a carrier's PDF. Document Studio extracts the fields you defined: carrier, PRO number, dates, origin and destination, weight, class, line haul, fuel surcharge and each accessorial, plus the POD's signature, delivery date and any exception the receiver noted.
Every carrier's invoice layout returns the same record, so the audit rules are written once.
Check every charge against the agreed rate before anyone pays it
Line haul and fuel surcharge are checked against the contract rate and the rate confirmation, and the billed weight and class against the BOL. Every accessorial needs a reason on file: detention needs the time on site, a lift gate needs the order that asked for one. An invoice that passes keeps moving. One that doesn't stops in a review screen with the charge, the rate and the evidence side by side.
Set the hold conditions once (an overcharge above tolerance, a duplicate PRO number, no POD) and only those invoices wait for a freight auditor or AP.
No signed POD, no approval, and every exception goes to a claim
Each invoice is held until a signed POD stands behind it. The POD's delivery date, pieces and signature are checked against the invoice and the BOL, and a short, damaged or refused delivery noted on the POD is flagged for a claim instead of being paid in full.
The POD that proves delivery also carries the times that settle a detention dispute.
Approve clean invoices where freight and AP already work
Clean invoices post to your TMS and ERP for payment, in Oracle Transportation Management, SAP Transportation Management, NetSuite, QuickBooks or the system you run. Payment runs in your ERP as it does today. Disputed charges go back to the carrier with the evidence attached: the rate confirmation line, the BOL weight or the POD times.
Each decision an auditor made is recorded against the PRO number for the next carrier review.

Fields captured
Our agents are extroverts.
Cloud storage like S3, Google Drive, Dropbox and Box. Databases and warehouses like Snowflake, BigQuery, Postgres and SQL Server. Accounting, ERP and CRM systems like QuickBooks, Xero, SAP, NetSuite, Salesforce and HubSpot. Project trackers like Jira, Asana, ClickUp and Linear. And anything with an API.
Live on one carrier group first
Nobody on your side writes code, and your current payment run stays as it is. The audit is set up on your own carriers' paperwork and proven on a few of them before the rest join.
Book a consultation
We go through a month of freight bills with you: which carriers send EDI and which send PDFs, where the PODs come from, and which charges your auditors question most.
Built on your carriers' paperwork
Your contract rates, tolerances and accessorial rules, and the connection to your TMS or ERP, are set up on real invoices and PODs from your carriers.
Start with a few carriers, then add the rest
A handful of carriers runs live within days. When the held charges match what your auditors would have caught, the other carriers follow on the same rules.
Built for the teams that check what carriers bill
A freight invoice audit on every bill before it reaches the payment run, and accessorials that come with a reason or don't get approved.
Each client's carrier invoices audited against that client's rates, with the POD attached before you bill the client.
Carrier invoices checked against the rate confirmation you issued, so a changed rate is caught before the carrier is paid.
More shipments audited per auditor, with PODs read for you and only the held charges left to review.
Freight bills audited on arrival, overcharges held before payment
Your lane rates stay with you
Freight invoices and rate confirmations show what you pay each carrier on each lane, and PODs carry your customers' delivery addresses and their receivers' signatures. A competitor or a carrier who sees your rates knows where to price against you.
- Encrypted in transit and at rest.
- Freight bills, PODs and rate confirmations are never used to train models.
- Access by role, client and carrier, with every audit decision recorded against the PRO number.
- Retention you set: processed invoices and PODs are deleted on your schedule.
- Self-hosted deployment for 3PLs and audit providers whose client contracts keep freight data in their own environment.
What freight audit teams ask before they start
Carrier freight invoices as PDFs and EDI 210s, rate confirmations, bills of lading, signed PODs and delivery receipts, delivery notes and CMR documents. Contract rates come from your TMS, and you can add any other paperwork your carriers send with an invoice.
On your own PODs. In a consultation we read a sample of your signed PODs and delivery receipts, driver photos included, and show the signature, delivery date, pieces and exceptions pulled from each one. You see on your own paperwork what proof of delivery automation catches before you commit to anything.
LLMWhisperer is Unstract's OCR API: it turns each invoice page into text with the layout kept, so the charge lines stay in their table. Document Studio then extracts line haul, fuel surcharge and each accessorial into the same JSON record for every carrier, and you can call it as an API endpoint per document type.
Look for one that reads every carrier's layout without a template per carrier, returns the same fields every time, and shows where on the page each value came from. Unstract does all three, and Flow adds the audit itself: rates, weights, accessorials and POD checks, with a person on the charges that fail.
No. Unstract audits each invoice, approves the clean ones and posts them to your TMS or ERP. Payment runs in your ERP on the schedule you already use, so your bank controls and approval limits don't change.
No. Drivers keep capturing PODs the way they do today, on paper, by photo or in a carrier's app. Unstract reads the signed PODs once they arrive and checks them against the invoice and the BOL.
Most freight invoice automation stops at capture: the invoice is read into fields and an auditor still compares it to the rate, the BOL and the POD. Unstract runs those comparisons on every invoice, holds the charges that fail, and posts the rest.
The invoice stops. A PRO number already billed or paid goes to a freight auditor or AP with the earlier invoice beside it. An invoice with no signed POD waits until one arrives, and every other invoice keeps moving.
To the systems your freight and AP teams already use, such as Oracle Transportation Management, SAP Transportation Management, NetSuite or QuickBooks. Disputed charges go back to the carrier with the rate confirmation line, the BOL or the POD that supports the dispute.
Unstract is SOC 2, ISO 27001, GDPR and HIPAA compliant. Invoices and PODs are encrypted in transit and at rest, never used to train models, and kept only as long as you choose. Self-hosted deployment keeps processing in your own environment; details are in the Trust Center.
No developers. We set up the audit around your carriers, your rates and your TMS or ERP in a consultation, run it on a few carriers, and the first of them usually go live within days.
