What to ask an accounting provider's client references

A useful reference has worked with the provider on a problem resembling yours and can describe what happened. Someone praising an annual personal tax return offers limited evidence about a multi-entity monthly close. Ask for references whose service scope, accounting complexity, and involvement with the delivery team match the proposed engagement.

The California Board of Accountancy recommends word-of-mouth referrals from people who have used a CPA's services as a starting point for selection. Treat provider-arranged introductions as one part of your process. The provider chooses whom to introduce, and the relationship may have changed since the reference's experience. A positive call can establish useful evidence of fit without proving that every future month will run the same way.

Get permission before contacting the reference. Offer a short agenda and explain that you do not need confidential financial figures. Ask whether the person managed the engagement directly and when they last used the service. If their only contact was with a partner who has since left, record that limitation.

Start with the work the reference expected and what their company had to do. Then follow one ordinary month from inputs to review. Ask when they supplied information, what questions came back, who reviewed the results, and whether unresolved items were visible. This shows the operating effort behind a statement that the firm was responsive.

Ask about a real complication they are comfortable discussing: a staff absence, an unusual transaction, a late document, or a report that needed correction. What did the provider communicate before the deadline? Who took ownership? How was the matter closed? Do not press for names, confidential documents, or allegations about other clients.

Listen for the cause behind the outcome. A late report may reflect unfinished reconciliations, missing client information, or an unrealistic date agreed during sales. Ask what both parties did after the problem became visible. The distinction matters because changing providers will not fix a delay caused by your own unavailable source records.

Use a simple evidence note: situation, expected result, observed action, outcome, and relevance to your company. For example, a reference may explain that the provider issued a clear incomplete-items list before close, but the client's operations team took a week to answer. That supports a conclusion about transparency, while leaving speed under your own input conditions untested.

Compare references using the same important questions, while allowing the conversation to follow useful detail. A long checklist can crowd out the best evidence. If one reference has unusually clean records and a large internal finance team, reduce how much their smooth experience influences a decision for a founder-led company with a backlog.

References cannot verify every qualification, security control, or legal authority. Check those through the appropriate primary evidence. The California Board of Accountancy distinguishes authorization to perform a service from experience and competence in that work, and advises buyers to check both. NASBA's CPAverify provides public access to board-supplied licensing data. A client saying their accountant is excellent does not replace a license check when the assignment requires one.

Bring unresolved delivery questions back to the provider. If references describe a dedicated reviewer, ask whether your quote includes the same role. If turnaround depended on a particular client portal or input deadline, include that dependency in onboarding. If an enthusiastic reference paid for controller support while your quote includes bookkeeping alone, correct the comparison.

Write down what the reference actually established, what remains uncertain, and which proposed terms should change. Avoid turning qualitative calls into a false mathematical ranking. Two carefully matched references with specific delivery examples can be more informative than a large collection of broad compliments.

An inability to provide a suitable reference deserves a follow-up, not an automatic allegation of poor service. Confidentiality restrictions, a new service line, or a different customer base may explain it. Ask what other relevant evidence the provider can offer, such as a properly anonymized sample or a bounded paid pilot, and assess the remaining uncertainty openly.

Before choosing, reread the notes alongside the proposal and sample work. The decision should connect the observed service to your actual constraints: staff availability, record quality, reporting needs, and tolerance for dependence on one person. Keep the reference notes private and use them to shape the engagement, rather than publishing another client's comments as an endorsement.
