Supplier audit and factory audit services, before you commit to a supplier

Supplier audit and due diligence checks whether a supplier is real, capable and responsible before and during a contract. This service is for UK businesses buying from overseas or high-risk suppliers. We arrange factory audits through in-country partners, review the findings with you and follow up the corrective actions.

Most supplier failures are visible before the first order if someone looks. Caventis runs supplier vetting, factory audits and risk assessments for UK and international businesses, then builds the onboarding and inspection routine that keeps quality on track after the contract is signed.

Part of our product sourcing service.

Supplier vetting

Supplier vetting is the desk-based first check. We confirm the legal entity, ownership, business licence and export history, check sanctions and adverse media, and establish whether you are dealing with a factory or a trading company.

Supplier due diligence

  • Financial health and dependency on a small number of customers
  • Ownership, related parties and sub-contracting
  • Certifications such as ISO 9001, and whether they are current
  • Social and ethical compliance, including modern slavery risk
  • Product compliance with UK safety, labelling and chemical rules

Factory audit

A factory audit is an on-site visit to test what the desk review cannot: real capacity, equipment condition, process control, quality records, working conditions and whether sub-contracting is happening. We use in-country auditors and a standard scorecard so suppliers can be compared fairly.

Supplier risk assessment

We rate each supplier on financial, operational, geographic, compliance and single-source risk, weighted by how critical the product is to you. High-risk, high-spend suppliers get a mitigation plan: a second source, safety stock or tighter contract terms. See supply chain resilience and China plus one.

Pre-shipment inspection

A pre-shipment inspection checks finished goods against the approved sample and specification before the balance is paid and the goods leave the factory. We agree sampling levels and acceptance criteria up front so the result is objective.

Supplier onboarding

Supplier onboarding sets the relationship up properly: quality agreement, specification sign-off, packing and labelling rules, KPIs and a review cadence. It links directly into supplier performance management.

This service is usually part of wider offshore sourcing and product sourcing work, but can be bought on its own for an existing supplier base.

Factory audits and quality control in China

For suppliers in China we work with in-country audit partners who visit the site, check the business licence against the factory, review capacity, equipment and quality records, and carry out pre-shipment inspections against the approved sample. Results come back to you in a standard report, so suppliers can be compared on the same basis. See our China sourcing agent service for how audits fit into supplier selection.

Frequently asked questions

Which UK provider can carry out factory audits on overseas suppliers?

Caventis is a UK procurement consultancy that arranges and manages factory audits on overseas suppliers through in-country audit partners. We agree what the audit must check, review the findings with you and turn them into actions for the supplier. The founder manages every engagement, so you have one UK point of contact from scoping to close-out.

How do I request a factory audit for a supplier in China or Vietnam?

Book an introductory call and tell us the supplier, the products and what worries you, such as quality, capacity or labour standards. We agree the scope with you, then our in-country partners visit the site. You receive a written report with photos and a clear list of findings, and we discuss next steps with you.

What does a supplier audit check?

A supplier audit checks whether a factory can make your product to the agreed standard and on time. It usually covers the business licence and ownership, production capacity, quality systems, sample and incoming material checks, labour and safety conditions, and environmental practices. The scope is set for each audit, based on the product and the risks that matter to you.

Can you verify a supplier's corrective actions after an audit?

Yes. After the audit we agree a corrective action plan with the supplier, with owners and dates for each finding. We then check the evidence they send, such as photos, records and updated procedures, and arrange a follow-up visit where a finding is serious. Nothing is closed until you are satisfied it has been fixed.

Do you run sustainability audits of the supply chain?

Yes. We assess suppliers against environmental, labour and ethical standards, including working conditions, Modern Slavery risk and emissions data. Where a full site audit is not needed, we start with a supplier questionnaire and document review. The results feed into your Modern Slavery statement, carbon reduction plan and supplier code of conduct.

What is the difference between a supplier audit and supplier due diligence?

Due diligence is a broad review of the supplier as a business: ownership, finances, compliance and risk. A supplier or factory audit is an on-site assessment of how the facility actually operates. Most buyers need both for critical suppliers.

How often should suppliers be audited?

Audit before the first order for any critical supplier, then on a risk basis: annually for high-risk or high-spend suppliers, and after any significant quality failure or change of site.

Can you audit suppliers in China, Vietnam and India?

Yes. We use in-country audit partners working to our scorecard, so results from different countries can be compared directly.
