Accounting-provider due diligence should establish who prepares the work, who reviews it and how the buyer retains control of records and decisions. A firm can present broad credentials while proposing a delivery team or access model that does not fit the engagement. Focus on the actual service and verify specialist claims through the appropriate current channels.

## Confirm the counterparty and team

Record the contracting entity, delivery locations, named service lead and any subcontractors. Ask who performs routine entries, reconciliations and review. Distinguish the firm's overall experience from the proposed individuals' relevant work and availability.

Check business identity through the buyer's normal controls. Where tax-agent or audit services are claimed, use the relevant official verification process and qualified review. The FTA provides registered-tax-agent information; the Ministry of Economy and Tourism provides auditor services. A general bookkeeping offer should not be treated as proof of either specialist status.

## Examine the control model

Map access to accounting systems, source documents and any submission or payment functions in scope. Assign permissions appropriate to preparation, review and approval. The buyer should retain ownership and recovery control of its accounts rather than depending on shared credentials held only by the provider.

For example, a provider may need bank statements to reconcile transactions without needing authority to release payments. Ask for a role-based access proposal that reflects that distinction. Convenience during onboarding is not a sufficient reason to combine unrelated authorities.

## Review record continuity and confidentiality

Ask how documents and working files are stored, protected, retained and exported. Have appropriate legal and security reviewers assess the arrangement. Identify what happens if the service lead leaves or the contract ends, including access to historical reconciliations and explanations of adjustments.

Request a fictional or properly anonymised sample pack and evidence of the review process. A polished dashboard should not substitute for traceable supporting records. Use references from comparable accounting complexity and a controlled first period where important capability remains uncertain.

## Keep the approval service specific

Document accepted scope, limitations and outstanding conditions. Revisit the affected review when subcontractors, systems, access or specialist services change. Due diligence should give the business a clear view of the team and controls supporting its accounts, rather than an unrestricted statement that a familiar firm can handle every financial task without further oversight.
