Your HMRC data. Retrieved, normalised, audit-ready.
Grant access once on your HMRC (His Majesty’s Revenue and Customs) Government Gateway account, and BorderAudit retrieves your complete customs declaration history — up to two years of imports, normalised and ready for analysis, typically in under an hour. No downloads. No spreadsheets. No missed data windows.
Your declaration data exists. Getting it is the problem.
Everything a post-clearance audit needs is already held by HMRC — commodity codes, customs values, duty paid, origin, dates. But retrieved by hand, that history arrives in expiring reports and fragmented exports, and the picture is never quite complete.
Grant access once. That’s the setup.
Authorisation is a standard third-party grant on your Government Gateway account — the same mechanism your accountant or customs broker already uses. It takes about two minutes, it’s scoped to customs declaration data only, and you can revoke it instantly whenever you choose.
- No bespoke integration, no API keys, no development
- Customs declaration data only — no banking, no tax, no VAT
- Retrieval starts automatically the moment access is granted
- Revocable from your Government Gateway account at any time

From authorisation to audit-ready, in six stages.
The whole pipeline runs itself: you authorise once, and your declaration history flows from HMRC into one clean, normalised model — then stays current as new imports clear.
- 01 · AUTHORISEGrant access onceA standard third-party authorisation on your HMRC Government Gateway account — the same mechanism accountants and customs agents use. About two minutes, no development.
- 02 · DETECTDetected instantlyBorderAudit spots the new access grant automatically and queues the data request. Nothing for you to configure, upload or export.
- 03 · RETRIEVEHistory, in optimised chunksYour declaration history is requested in intelligent time-period segments rather than one giant pull — maximising completeness and avoiding HMRC system timeouts.
- 04 · NORMALISEOne clean data modelCDS (Customs Declaration Service) and MSS (Management Support System) records are reconciled into a single normalised model — line-level, consistent, queryable.
- 05 · MONITORKept current automaticallyAs your import activity continues, new data is retrieved and processed continuously — and expiring TRE reports are captured before their 30-day window closes.
- 06 · SERVEEvery module reads from itThe normalised dataset becomes the foundation the whole platform reads — audit automation, compliance checks, reclaim preparation, dashboards.
Grant access once.
One Government Gateway authorisation, and your CDS and MSS declaration data is retrieved, normalised and analysed — watch how the connection works.
Built for completeness, not convenience.
What used to take weeks now takes an hour.
One dataset. Every module reads from it.
HMRC data automation isn’t a feature you use — it’s the layer everything else stands on. Once your declaration history is retrieved and normalised, the rest of the platform works from the same single source of truth.
Automated post-clearance analysis runs across the normalised dataset — every declaration line checked, not a sample.
EXPLORE →Dashboards, rulesets and case management — the full platform view built on the same data foundation.
EXPLORE →If HMRC opens a compliance check, the audit workflow scopes and samples from data that's already retrieved and normalised.
EXPLORE →Readiness scoring reads the same declaration history — see what an auditor would see, before an auditor does.
EXPLORE →Good data finds what sampling misses.
What the audit finds
Complete data is what makes the findings complete. Sampling misses the errors that sit outside the sample, and with 32% of the declarations we've audited containing errors, a full declaration history is the only reliable starting point.
- Finding 01
Entries nobody has reviewed
Declarations made by agents and carriers in your name that never crossed your desk, now readable line by line.
- Finding 02
The full reclaim window
Overpayments across the period you can still claim, with the oldest entries flagged before they fall out of reach.
- Finding 03
Inconsistencies across sources
Data that disagrees between declarations, so errors in the record itself are found rather than inherited.
£341K identified. £272K still recoverable. £69K already lost to time.
The earlier the data is retrieved, the less of the window is lost. The £69K in this case had already passed the three-year limit.
