Choose a question the provider can finish

An observed work session can help you evaluate a prospective accounting provider before giving it a recurring assignment. Pay for a small piece of work, give every shortlisted provider the same evidence, and ask the person who would handle your account to explain the result. The useful evidence is how that person connects records, identifies missing facts and leaves a usable handover.

Choose a contained question, such as explaining one processor settlement or reconciling a short supplier statement. Avoid using the session to obtain a free cleanup of your books. Agree the fee, time limit, permitted records and intended output in advance. A provider should be able to decline a sample that needs specialist expertise or information you cannot safely disclose.

Keep the exercise separate from a full accounting diagnostic. You are observing a specific working method, not establishing that the entire ledger is correct. A successful sample supports the decision to proceed with a defined engagement; it does not prove every member of a large team will produce identical work.

Prepare evidence with one deliberate complication

Use a closed historical period for which you already understand the outcome. Remove confidential identifiers and preserve the relationships between documents. If a customer code changes in the invoice, change it in the remittance too. Otherwise you will be measuring the provider's ability to compensate for a damaged exercise.

Include an ordinary complication that occurs in your business: a fee deducted from a payout, a credit issued after a bill, or a payment covering two invoices. Do not plant an obscure trick. Write down the facts available, the answer supported by those facts, and the question that remains genuinely open.

The IRS describes invoices, receipts and other supporting documents as evidence behind business records. A sample built only from a summary spreadsheet cannot show how the provider uses that evidence. Include the underlying record needed for the selected question while limiting exposure of unrelated transactions.

Invite the assigned practitioner

Ask who will perform the session and whether that person would prepare or review your recurring work. A polished presentation from a sales specialist provides different evidence from a practical explanation by the proposed delivery team. Both conversations can be useful, but record which one you observed.

Allow reasonable preparation time and tell the provider whether it may use its normal tools. If staff normally collaborate, ask them to show where that collaboration occurs. A silent reviewer appearing at the end can hide how questions reach the person authorized to resolve them.

Avoid judging typing speed or familiarity with your preferred keyboard shortcuts. Focus on whether the practitioner can describe the evidence, propose a defensible treatment, and explain what they would withhold from final approval. Give the same opportunity to clarify the brief to every candidate.

Observe the questions before the calculation

A useful practitioner may pause before entering anything. Listen for questions about the legal entity, date range, accounting basis and whether the source report is complete. Those questions should connect to the assignment. A long generic questionnaire can consume the session without clarifying the selected transaction.

When a fact is missing, ask how the practitioner would record the uncertainty and keep the rest of the work moving. Distinguish a reasonable provisional working assumption from a posted entry presented as settled. The answer should identify who supplies the missing evidence and who approves the conclusion.

Take short notes using observable actions. Write that the provider traced the fee to the settlement statement, or asked for the missing credit note. Avoid labels such as confident or impressive unless you can explain what the practitioner did to earn that judgment.

Check the arithmetic and the residual

In an illustrative settlement exercise, gross receipts are $18,400, customer refunds are $620, processing fees are $510 and the payout is $17,270. The bridge is $18,400 less $620 less $510, which equals $17,270. A provider should be able to show the bridge and identify which documents support each amount.

Now give the provider a bank deposit of $17,120. The unexplained difference is $150. Ask what evidence would distinguish a reserve movement, another fee, a timing difference or an error. The purpose is to observe investigation, not to reward a guessed balancing entry.

If the practitioner proposes a journal, request the accounts, date, description and supporting reference. You should be able to tell whether it records a real event or merely forces two totals to agree. Keep the exercise outside production so no trial entry changes your live records.

Require a handover someone else can read

The session should end with a short deliverable: the calculation, source references, unresolved questions and proposed next step. Ask a colleague who did not attend to read it. Can that colleague find the original settlement, understand the remaining $150 and know whether anything was approved?

This test reveals a problem that a live explanation can conceal. A practitioner may explain the answer clearly while leaving a spreadsheet whose labels make little sense later. Recurring accounting work needs a record that survives staff leave and provider changes.

Ask how corrections would be added after the session. A changed amount should have a reason and an identifiable version. You do not need an elaborate document system for a short exercise, but overwriting the only explanation makes the result difficult to review.

Compare the evidence and close the evaluation

Use a small assessment sheet covering source tracing, treatment of uncertainty, calculation accuracy and handover clarity. Record gaps with their consequences. A missing fee reference might be fixable through a reporting convention; an insistence on posting an unexplained difference deserves a more serious follow-up.

Do not pretend a numerical score predicts the quality of the entire relationship. Consider the exercise alongside credentials, capacity, relevant experience and the proposed engagement. Ask the preferred provider how it will address the specific weakness you observed and put any material delivery requirement into the scope.

Finally, revoke evaluation access and agree what happens to the supplied files. The FTC recommends limiting sensitive-information access and protecting data shared with outside parties. Use a company-approved transfer method and retain your copy of the work sample, the provider's response and the decision note.
