Make the extra request visible before it becomes a bill

A change order is useful when the work being requested differs materially from the agreed accounting engagement. It records what changed, why the additional work is needed, and what each party is approving. The format can be short, but the decision should be clear before effort or deadlines make refusal difficult.

Start by locating the existing scope. A task can be unfamiliar without being extra. Ask the provider to identify the relevant agreement line and explain the difference. A new legal entity, a historical repair, or a technical research assignment may justify additional work; repeating an agreed reconciliation does not become a new service simply because it took longer than expected.

Write a request that someone outside the conversation can read

Describe the triggering fact, affected entities and periods, requested result, and reason for the timing. State whether the assignment changes recurring service or ends after a defined deliverable. Identify information the client must supply and any specialist engagement needed.

AICPA Member Insurance Programs' guidance on additional work distinguishes minor changes from significant assignments or services under different professional standards. Ask the provider which form of documentation is appropriate. A short agreed amendment may work for a narrow change; a substantial new service may need a separate engagement letter.

Distinguish discovery, recommendation, and execution

Sometimes the provider cannot responsibly price the repair until it investigates. In that case, authorize a bounded diagnostic first and require a return to the decision-maker before corrections begin. Do not give an unlimited instruction to fix everything when the affected records and consequences are unknown.

Use an explicitly illustrative request: the business discovers that a newly connected sales channel imported overlapping dates. The first assignment might identify the duplicated population and propose a correction method. A second approval could authorize the reviewed correction in the live ledger. Separating those stages allows the company to understand the effect before entries change.

The same distinction applies to advice. Asking what a rule might mean is different from commissioning a researched conclusion for a transaction and different again from implementing the decision. Record the intended use and the facts the professional may rely on. Preliminary observations should not silently become final instructions.

Price the additional work and the work it displaces

Ask whether the fee is fixed, estimated, hourly, or subject to a cap, and what would trigger another approval. Establish how the extra work interacts with a retainer or recurring package. If an existing allowance is being used, show the remaining capacity after the change.

The Journal of Accountancy advises firms to communicate expected fees above estimates and seek written approval where possible. Request that warning while you still have options. An overrun notice should explain completed work, the reason for the change, and what remains, rather than presenting a larger number without a decision.

Capacity also matters. An urgent project may delay the ordinary close or consume the reviewer's availability. Ask for the proposed sequencing and decide which commitments can move. Paying a rush fee does not create missing source records or remove the need for appropriate review.

Give approval authority to a named role

Identify who may approve new fees, accounting corrections, and deadline changes. Those can be different people. A department manager who supplies a contract should not automatically commit the company to a specialist engagement. Conversely, a purchasing approver may need a finance reviewer to assess the accounting consequence.

Use the agreed communication route and retain the accepted version. The CAS engagement guidance recommends documenting scope modifications and communicating them to the delivery team. Make sure the person performing the work has the same boundary that the client approved, including exclusions and stopping points.

Close the change as deliberately as it began

Check the delivered result against the approved request. Record remaining limitations, corrections posted, reports updated, and any continuing task assigned to routine service. Match the invoice to the agreed fee basis and approved amendments. A completed project should not create an unexplained permanent increase in the monthly bill.

If the change reveals a recurring need, decide whether to amend the ongoing engagement. If it was a one-time exception, return to the original scope. Keep the change log concise enough to review at renewal, with a link to the evidence behind each entry.

Over time, the log can show where the original engagement is underspecified. Repeated requests for the same schedule may justify buying it routinely; repeated correction work may point to a process defect. That is a useful commercial discussion because it starts with observed work instead of vague complaints about scope creep.
