Every freight invoice checked against your contracted rates, automatically. Road, Air, Sea — line by line, shipment by shipment.
Surcharges, fuel adjustments, currency conversions, weight brackets, accessorials — each carrier invoice has dozens of line items priced on its own logic. Finance teams don't have the hours to verify each one against the contract. Errors slip through. They become cost.

On Oracron's flat fee you keep €6,800 — 100%. A contingency auditor would take €1,700–€3,400 of that.

Sentra is not a black box. Every decision is logged, every rule is visible, and nothing leaves your tenant without a policy you set.
Why a line was flagged, which contract clause was used, what the deviation was — all reviewable.
Dispute letters are drafted; they leave only when your approval rules allow it.
Every override or accept becomes signal. False positives drop as Sentra learns your tolerances.

Oracron is modular. Nexus manages contracts, Prism turns spend into analytics, Argus scores carrier performance, and Orbit runs procurement — all on the same data Sentra audits.
A freight invoice audit compares every charge on a carrier invoice against the contracted rate for that shipment — base freight by weight bracket, surcharges (fuel, tolls, remote area, customs), and accessorials. Sentra automates the full audit: it extracts the invoice via AI (PDF or CSV), normalises each line to a canonical fee taxonomy, looks up the contracted rate by route + weight + date, and flags any charge that doesn't match. Mismatches above your tolerance are auto-drafted as dispute letters with a per-line evidence table.
Sentra brackets the rate on our independently computed chargeable weight — derived from the shipment's gross weight, volume (CBM), and loading metres (LDM) using the tariff's contracted conversion factor. The expected total is then built up from your rate card and compared to the invoiced amount. The common overcharge patterns it catches: inflated chargeable weight, wrong tariff zone, surcharges applied to a non-eligible lane (e.g. remote-area fee on a mainland postcode), fuel surcharge using the wrong weekly index, and percent-of-freight surcharges compounding on each other.
Yes. Sentra is carrier-agnostic — the AI extraction handles invoice formats from DHL, DB Schenker, Kühne+Nagel, Rhenus, Dachser, GEODIS, FedEx, UPS, and others. The 152-code fee taxonomy maps each carrier's labelling (e.g. K+N "Zonentarif", Schenker "Frachtkosten Hauptlauf") to canonical codes, and the rate engine supports carrier-specific chargeable-weight factors per lane (e.g. K+N Zonentarif 150 kg/m³ + 800 kg/LDM). New carrier templates are added without code changes.
Most customers go live within two weeks. The work is mostly importing your contracted rates per route and weight bracket — Sentra handles the rest.
PDF (with AI extraction, including scanned invoices) and CSV. Email-in and SFTP drop also supported for high-volume accounts.
Yes. Rates are imported per route and weight bracket — that's how Sentra knows what the invoice should be. We support importing from spreadsheets, carrier rate cards, and Nexus.
Sentra drafts a dispute letter with a line-level evidence table and routes it through your approval policy. Once sent, carrier replies are tracked in the dispute portal until the case is closed or a credit note is matched.
No. Your invoices, contracts, and dispute data stay in your tenant and are never used to train models for other customers.
