Identity
- Full legal name and NZBN.
- Entity type and company number.
- Trading names and how they relate to the legal entity.
- Registered office and service address.
Standing
- Current status on the register.
- Incorporation date and time trading under the entity.
- Any factual flags such as liquidation, receivership or removal.
Context
- Who controls the company and any related companies.
- Any public record of enforcement or regulatory action relevant to their sector.
- Whether the brand history matches the legal entity history.
Decision and follow up
Write down what you checked and what you found, even briefly. A short note on file shows you did reasonable checks and helps the next person who deals with the same company.
Decide what to monitor. Anything ongoing should be watched so a later change reaches you.
Questions and answers
Does the same checklist work for customers and suppliers?
The core checks are the same because they are about the legal entity. What changes is emphasis. For a customer you may care more about credit risk, for a supplier more about their ability to deliver.
