Supplier Audit & Due Diligence

Know who you are buying from before you commit.

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

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.

Frequently asked questions

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.
