For EU exporters to UK & US
AI audits your last 12 customs invoices in 5 minutes.
Tariffs change weekly. Brokers fall behind. You overpay daily.
Free during beta.
Real case, May 2026
€25,000 in overcharges found
in 8 months of UK shipments by an EU exporter — discovered by accident. The same pattern repeats across every category, every corridor, every week new rates take effect.
Quick estimate
Rough estimate based on industry-average broker error rates across categories (€100–€500 per shipment).
How it works
Stay anonymous. Cancel anytime.
Drag & drop your last 1–12 customs invoices (PDF). Takes 30 seconds.
AI extracts the data. Real HMRC + US TTB tariff tables run the math the broker should have.
Line by line. Reclaim from broker, switch broker, or sleep better knowing they're honest.
The dirty secret
USTR, HMRC, EU TARIC — between them they push dozens of changes per month. By the time your broker updates, you've already paid weeks of stale rates.
Volume, weight, alcohol content, ad valorem — small math errors silently inflate every duty line. One we audited got it wrong for 8 months straight.
Three regulatory waves hitting at once. Most brokers handle one, miss the other two. You absorb the gap silently.
EUR.1 / Form A not properly applied → you lose the preferential duty rate you were legally entitled to.
A single character difference in the HS code can swing duty 5–25%. Brokers get this wrong constantly — and you pay.
"Trust us" is the entire interface. You see a number on the invoice and pay it. We do the math they won't show you.
The daily bleed
Every week a new tariff, suspension, exemption or carbon levy takes effect somewhere between you and your customer. Brokers reconcile rate tables manually — sometimes weekly, often monthly. The gap is paid out of your margin, every single day, on every single shipment.

you pay the difference.

Great news. You'll have peace of mind, a benchmark for future shipments, and confirmation that your broker is doing the math right. Many brokers do.
We don't trust AI to do the math. AI extracts data from your PDFs (highly accurate). Tariff calculations use official HMRC and US TTB rate tables — deterministic, not guessed. Every line is verifiable.
