The native AI freight-cost referee for your SAP TM.
Chargytix AI is a native AI application — not a bolt-on, not a wrapper. It is built directly on SAP BTP and sits next to SAP TM and S/4HANA, predicts the right charge for every freight order, flags variances the moment a carrier invoice arrives, and runs the entire dispute back-and-forth with an audit trail your AP and audit teams can actually live with.
Freight invoices and shipper-expected charges almost never agree.
Detention, fuel, demurrage, surcharges, FX, contract variants — the gap between what TM expected and what the carrier billed is wide, frequent, and expensive. Most shippers either pay the variance silently or chase it through email chains that nobody can audit a year later.
Chargytix AI predicts the right charge using SAP TM's own settlement document, then runs a structured dispute when a carrier invoice diverges — with the carrier on a magic-link portal, not a generic email thread. Because it is a native AI application on SAP BTP, the data, the model context, and the posting back to S/4HANA all stay inside the SAP perimeter — no middleware, no copy-paste between systems.
Predict. Compare. Dispute. Post.
01
Predict
Reads the TM Freight Settlement Document (FSD) and produces an expected charge breakdown — base, fuel, accessorials — that the carrier should bill.
02
Compare
When the carrier invoice posts (MIRO), Chargytix AI reconciles line by line, computes the real variance and tones the case green / amber / red.
03
Dispute
High-variance cases auto-open a carrier-side magic-link portal. Carrier proposes counter-charges, AP team accepts or counter-offers, every step is timestamped.
04
Post
Once both sides agree, the resolved invoice is posted back into S/4HANA via the standard SAP inbound — the system of record stays clean.
What it actually looks like.
Real screens from the live product. Every variance, every dispute message, every charge element traces back to its SAP TM source.
Variance dashboard
Live view of variance MTD, freight orders settled, dispute pipeline and carrier scorecard.
Carrier dispute portal
Magic-link portal for carriers — no SAP login required. Carrier proposes counter-charges; AP team accepts or counters.
Variance alerts
Auto-triaged alerts on every freight settlement document. Tone-coded variance · multi-FSD aware · linked to source.
Cost distribution
Where the charge value sits, by carrier, lane and accessorial. Breaks the variance back into the cost driver.
Invoice verification
OCR-assisted invoice intake. Reads the carrier invoice line by line and reconciles against the SAP TM expected.
Audit log
Every action timestamped — predict, compare, dispute, post. Hand the trail to AP, audit or a regulator.
Six modules. One product.
Glass-Box Predictor
Predict expected charges from TM data with full reasoning chain. Audit-ready, no black-box "the AI said so".
Variance Worklist
Settlement-aware worklist with corrected SAP TM lifecycle states. Multi-FSD aware. One-click to open or repost.
Carrier Dispute Portal
Anonymous magic-link portal — no SAP login. Worklist + per-dispute drilldown + counter-proposal editor for the carrier.
Charge Validation
Live carrier master from CarrierMaster, not demo data. Validate every charge element against the contract.
Period-Close Cockpit
Glass-Box period-close reconciliation across the whole TM book. Pre-flag exposure before the shipper closes finance.
Carrier Scorecard
Variance behaviour, dispute outcomes, on-time posting — per carrier, per lane, per period. Negotiate next year on numbers.
Native SAP. No middleware.
