FAQs

It reduces audit risk by identifying and addressing compliance gaps early - helping you stay prepared ahead of an HMRC audit. It keeps operations running smoothly during audits and minimises financial exposure by preventing duty/VAT errors, misclassification, and valuation issues that lead to penalties or back payments. 

Preaudit health check: Comprehensive gap analysis across policies, data, controls, and supporting evidence. 

Mock audit: HMRC style walkthrough, with sampling, and documentation testing to assess readiness. 

Corrective action plan: Root cause analysis, control enhancements, SOP development, and targeted training.  

Post audit mitigation: Address findings, quantify exposure, implement remedial actions, and retest controls. 

Continuous monitoring (optional): Dashboards, customs intermediary oversight, and periodic internal reviews to maintain compliance.

  • Risk register with prioritised issues and owners 

  • Audit trail & evidence pack (policies, SOPs, sample files, screenshots) 

  • Corrective action plan with milestones and KPIs 

  • Controls library (segregation of duties, access, review steps) 

  • Training materials & quick reference checklists 

  • Executive summary that quantifies risk reduction and financial protection (e.g., avoided penalties, reclaims) 

No. We structure the process to be as light-touch as possible: short interviews, targeted sampling, and remote document reviews. Any on-site work is scheduled around your busiest periods. The goal is to maintain operational continuity and to not cause disruption. 

We use a central standard supported by local adaptation. Core compliance requirements are defined centrally for consistency, while each site documents its specific variation. Our testing and evidence process is applied uniformly across ensuring consistent regulatory assurance without compromising flexibility for local procedures.

A customs intermediary files entries, while your internal team manages day-to-day operations. We provide a structured audit-readiness and remediation framework that validates customs declarations, tests controls end-to-end - including classification, origin, valuation, and authorisations - and implements fixes with documented evidence. This gives you regulatory assurance beyond routine operations.

 

Discovery and health check - 2 - 3 weeks (depending on number of sites and volume to be audited. 

Mock audit and reporting - 2 - 3 weeks 

Remediation and re-testing - 4 - 12 weeks (depending on complexity) 

Work is phased to avoid operational disruption and focus first on high-risk, high-impact areas.

We measure: 

  • Audit outcomes: fewer findings and faster closure. 

  • Customs clearance performance: reduced shipment delays and improved declaration accuracy 

  • Financial impact: lower exposure to assessments and penalties, successful reclaims, improved duty and/or VAT accuracy, and cycle time savings. 

  • Control maturity: completion of corrective actions, adherence rates, and exception trends. 

Yes. Audit cycles and random checks are increasing, and retrospective lookbacks can run up to several years. Proactive readiness materially reduces exposure and typically costs less than reacting to findings—delivering risk reduction and financial protection.
