Audit my invoices
Kadix · built in-house

The AI that audits your invoices and negotiates your rates.

Kadix reads every line of every shipping invoice — UPS, FedEx, USPS, DHL, Amazon — benchmarks them against millions of historical shipments, files refund claims, and builds the playbook for every carrier negotiation we run.

Capabilities

Six things Kadix does that off-the-shelf tools don't.

§ 01

Reads every line of every invoice

Surcharges, address corrections, oversize fees, late-delivery refunds, dim-weight reclassifications. Kadix parses UPS, FedEx, USPS, DHL, and Amazon invoices natively — PDF, EDI 210, and CSV all land in the same schema.

Millions of shipments classified and growing weekly
§ 02

Builds your negotiation playbook

Before we meet with your carrier, Kadix models what your shipping costs would look like across every realistic offer. Discount sliders, dim-factor scenarios, surcharge caps, lane-specific pricing. We walk into every renegotiation with the answers.

Powers every Kadima carrier meeting
§ 03

Files your refund claims weekly

Late deliveries, wrong residential charges, address-correction errors, refund-eligible fuel surcharges. Kadix files them automatically every week, before the 15–30 day claim window closes.

High claim-approval rate across carriers
§ 04

Benchmarks against the database

Every recommendation is backed by real shipping data across $1.7B+ of audited invoices. You see what other shippers like you actually pay — same volume tier, same lanes, same product profile.

Benchmarks refresh weekly
§ 05

Per-client cost allocation

For 3PLs and multi-tenant operators, Kadix splits every audit and refund by end customer. Your billing team gets clean per-client P&Ls. Refunds route back to the right account automatically.

Built for 3PL operators specifically
§ 06

Carrier rate routing at print time

Every label can be shopped across your carriers and our GPO at print time. Lowest-cost-viable routing happens before the carrier ever sees the shipment. Saves 8–18% vs. carrier-default routing.

Optional, opt-in per workflow
Why we built our own

The audit-software market is full of resellers. We're not one.

Most "shipping audit platforms" buy parsing capabilities from a handful of vendors and slap a UI on top. We've never been comfortable with that. Three principles drove building Kadix in-house instead.

01

Built in-house

Kadix isn't a recently-acquired stack we white-labeled. We've written the parsing pipelines and benchmarking models in-house, on real customer invoices, every day.

02

Not for sale anywhere else

Kadix only runs on Kadima accounts. You don't get charged for the software; you get charged on the savings it helps recover and negotiate. Aligned incentives, not seat licenses.

03

Owned, not assembled

We don't sit on top of off-the-shelf audit APIs. The parsing, classification, benchmarking, claim-filing, and reporting are all our code. Which means when we hit an edge case, we fix it — we don't file a ticket.

The benchmark database

Every recommendation is grounded in real shipping data.

The thing that makes Kadix actually useful — instead of being another rules-engine that flags surcharges you could find with grep — is the benchmark database underneath it.

Years of carrier invoices across millions of shipments means we know what every kind of business actually pays for every kind of shipment. When Kadix flags a rate as off-benchmark, we have receipts.
