Due diligence / Checklist

Supplier due diligence: a checklist for procurement teams

Identify the legal entity, examine the evidence and assign the follow-up before you approve a supplier.

At a glance

  • Start with the contracting legal entity and the decision at stake.
  • Scale the evidence to the exposure and operational dependency.
  • Assign unresolved questions to an owner before approval.

Define what the supplier relationship puts at risk

Supplier due diligence begins with the relationship. A critical production supplier, a one-off purchase and a software service with access to internal systems create different dependencies. Establish the proposed commitment, payment structure and consequences of interruption before collecting documents.

Identify which teams need to contribute. Company information can support the review, while information security, contractual, operational and regulatory questions may need separate evidence and specialist owners.

Identify the company you will contract with

Match the company legal name, registration number and jurisdiction to the agreement. Confirm the relationship between the contracting entity and any brand or group name used in the sales process. Record the source used to resolve the company.

Where available, review company status, officers, shareholders and group relationships. A company record does not establish that an individual has authority to commit the business. Confirm signatory authority through your procurement and legal process.

What a procurement reviewer would ask about this report

Ownership, cash and charge records can all inform a supplier review. Their relevance depends on the commitment and the contracting entity. These source observations are starting points for questions, rather than a completed supplier approval.

Work through the evidence

Use this working checklist to structure an initial review. Ticking an item means your team has considered it; it is not a verification, a compliance certification or a completed approval. The checklist stays in this browser session.

Separate financial capacity from operational capability

Review available accounts and credit indicators with their dates and scope. Consider the supplier’s role in your operations and the commitments you are asking it to fulfil. A financial report cannot prove delivery quality, capacity, product security or the effectiveness of a continuity plan.

For a material dependency, agree what additional evidence is needed and who will assess it. That could include operational references, contractual protections or continuity arrangements. Record missing evidence as an open item with an owner and a due date.

Approve with a review plan

Keep the decision, exceptions and supporting information together. A clear approval says which entity was reviewed, which risks were accepted and which conditions must be met before trading. Unresolved material questions need an explicit outcome.

Set review dates and relevant event triggers after onboarding. Monitoring should lead to an assigned review, with a recorded conclusion and an escalation path for changes that affect a critical relationship.

Frequently asked questions

Your questions, answered.

01

What is supplier due diligence?

It is a structured review of a proposed or existing supplier, scaled to the relationship, exposure and requirements of your organisation.

02

What company details should procurement verify?

Start with the legal name, registration number, jurisdiction and contracting entity. Use source evidence and record the match.

03

Does this checklist complete an approval?

No. It is a working aid. Your organisation must assess the evidence, resolve exceptions and authorise the decision.

04

Should every supplier receive the same checks?

Set requirements according to materiality, operational dependency and your applicable policies.

05

Why review ownership and group structure?

They can clarify relationships and concentration. Disclosed group membership does not establish a guarantee or signatory authority.

06

Can a credit report confirm operational resilience?

No. Financial information supports one part of a broader review. Operational capacity and continuity require their own evidence.

07

What if supplier information is missing?

Record the gap, assign an owner and determine what additional evidence or approval is required.

08

Does a company register verify bank account ownership?

A company registry record alone does not establish bank account ownership. Handle payment account verification through a separate process.

09

When should suppliers be reviewed again?

Use a risk-based schedule and event triggers tied to the supplier’s significance and your internal policy.

10

Is this checklist stored on the server?

No. The interactive checklist runs in your browser and resets when the page is reloaded. It is not an audit record.
