Quick summary
A client due diligence checklist is your internal playbook for onboarding. Read this post to learn how to make it work for your team.

Too many financial institutions get stuck in long back-and-forths when onboarding new clients. Research from Fenergo shows that banks take an average of 95 days to complete a KYC review for a commercial client, while full due diligence takes even longer.

It’s practically impossible to avoid some level of follow-up and clarification, as there’s always going to be a missing document or an unanswered question, but a good client due diligence checklist will make your process faster and far more predictable. In this post, we’ll show you a template checklist to help improve your client due diligence procedure.

Ready-made client due diligence checklist

The due diligence checklist isn’t something your clients will ever see. It’s your internal guide that keeps your team members aligned, so each onboarding follows the same rules and covers the same risks, no matter who’s handling the account.

Identity and ownership verification

This section establishes who the client really is and who ultimately controls the business. It forms the foundation of your compliance process and ensures you are not onboarding unknown or high-risk parties.

1. Collect and verify the client’s legal business name and registration details

2. Confirm the registered business address

3. Identify all directors, signatories, and beneficial owners

4. Collect and verify government-issued ID for required individuals

5. Collect and verify proof of address

6. Run sanctions screening on all required parties

Risk assessment

In this section, you determine how much attention and monitoring a client will require over time. The outcome guides how strict your controls should be and whether additional safeguards are necessary.

7. Assign an initial client risk rating

8. Assess geographic risk

9. Assess industry risk

10. Assess ownership and control complexity

11. Assess transaction risk indicators

12. Determine whether enhanced due diligence is required

13. Document the rationale for the assigned risk level

Relationship purpose and expected activity

The following tasks help you define what “normal” looks like for the client relationship. By setting clear expectations up front, you can more easily spot unusual or potentially risky behavior later.

14. Record the stated purpose of the business relationship

15. Define expected products or services

16. Estimate expected transaction volume

17. Estimate expected transaction frequency

18. Collect source of funds information

19. Collect source of wealth information

20. Confirm the profile aligns with internal risk policies

Business and financial verification

This step confirms that the client’s business is legitimate, active, and financially sound. It also gives your team confidence that the relationship is built on accurate and current information.

21. Collect and verify incorporation or registration documents

22. Collect and verify required business licenses

23. Collect and review organizational structure

24. Collect and review financial statements

25. Verify bank account details

26. Collect and verify tax identifiers

27. Confirm proof of active business operations

Internal approvals

These tasks represent your final internal checkpoint before the relationship is formally approved.

28. Complete compliance review

29. Complete risk review

30. Obtain manager or compliance officer approval

31. Record approval date and approver

32. Store all documents according to retention policy

Ongoing monitoring

Due diligence doesn’t stop once a client is onboarded. This section makes sure the relationship stays up to date as the client, regulations, or risk profile changes.

33. Assign client review frequency

34. Define monitoring triggers (ownership changes, large transactions, etc.)

35. Assign monitoring responsibility

36. Schedule next review date

37. Set reminders for periodic re-verification

FAQ

What’s the difference between a client due diligence checklist and an onboarding form?

A client due diligence checklist is an internal process document that defines what you need to collect or approve. On the other hand, an onboarding form is simply the client-facing way you gather some of that information.
