Short answer
An outside accounting support firm can sit on management's side of the audit: preparing books and schedules, managing the request list, answering routine questions and coordinating parent companies and third parties. The independent CPA firm keeps everything that makes it the auditor: planning, risk assessment, sample selection, testing, confirmations, conclusions and the opinion. The two roles run in parallel, and management stays responsible for the financial statements throughout.
Key takeaways
- The company engages and pays its independent auditor directly; an audit-support provider is not a party to that engagement.
- Audit support works for management, so its schedules and explanations are management information that the auditor tests like any other.
- AICPA independence rules limit the non-audit work an audit firm can do for its own audit client, which is the gap a separate support provider fills.
- Management must still review and approve the books, the financial statements and the representation letter.
- Clear protocols (one request tracker, named contacts, agreed turnaround times) matter more to audit speed than the number of people involved.
Where the line sits
| Activity | Company and its audit-support provider | Independent auditor |
|---|---|---|
| Keeping the books and closing the year | Yes | No |
| Preparing reconciliations, schedules and lead sheets | Yes | Tests them |
| Drafting accounting-policy memos | Prepares for management approval | Evaluates them |
| Setting materiality and selecting samples | No | Yes |
| Sending bank, customer and legal confirmations | Supplies contacts and authorizations | Sends and receives directly |
| Proposing audit adjustments | May identify and propose before fieldwork | Proposes during the audit |
| Approving adjustments and financial statements | Management decides | Evaluates the result |
| Signing the representation letter | Company officers only | Receives it |
| Issuing the audit opinion | Never | Yes |
NYBACS operates entirely in the left-hand column. We are not a CPA firm and do not perform audit procedures, sign audit reports or give assurance.
Why a separate support role exists at all
In a large company, the in-house finance team prepares for the audit. Early-stage and foreign-owned companies often have no US finance team: the founder runs the business, a part-time bookkeeper records transactions, and the parent's accountants are in another time zone.
The obvious shortcut is to ask the audit firm to fix the books. AICPA independence rules allow an audit firm to provide certain non-audit services only if management takes responsibility for them and designates someone with suitable skill, knowledge or experience to oversee them, and some services are prohibited altogether. Many small companies cannot meet that oversight condition comfortably. A separate provider working for management lets the auditor stay independent while the company still gets the preparation work done. It also keeps the auditor's time focused on testing, which is the work the company is actually paying the audit firm to perform.
What support looks like through each audit phase
- Before engagement. Assess readiness, identify likely problem areas and help management request proposals from independent CPA firms. The company chooses and engages the firm.
- Planning. Receive the PBC list, map each request to an owner and date, and supply prior-year statements, organization details and key contracts.
- Year-end close. Close and reconcile the books, prepare schedules and lead sheets, and draft policy memos for management to approve.
- Fieldwork. Answer routine questions, pull sample documents, provide confirmation contacts, and escalate judgment questions to management.
- Wrap-up. Help management evaluate proposed adjustments, update schedules for accepted entries, and walk officers through the representation letter before they sign.
- After the report. Post final adjustments to the ledger so the next year opens on the audited balances, and record lessons for the following year.
How to keep the roles clean in practice
A few working rules prevent confusion:
- One request log. Every auditor request, response and open item goes in a single tracker visible to management, the support provider and the auditor.
- Judgment questions go to management. Questions such as "why was this estimate used?" or "is this customer likely to pay?" are answered by management, informed by the support provider's analysis.
- No filtering of third-party evidence. Confirmations and legal letters go directly between the auditor and the third party.
- Transparency about who prepared what. The auditor should know that schedules were prepared by an outside provider on management's behalf, and who reviewed them inside the company.
These rules also protect the company: if the auditor ever doubts that management understands its own numbers, the audit becomes harder, not easier.
It also helps to put the arrangement in writing at the start. A short scope letter between the company and its support provider should list the schedules and tasks covered, who inside the company reviews and approves them, and confirm that the provider does not perform audit procedures or represent the company in disagreements with the auditor. Sharing that scope with the audit firm at planning removes any doubt about who is doing what.
Common mistakes to avoid
- Expecting an audit-support provider to deliver a specific audit opinion.
- Letting the support provider answer judgment questions the auditor directed to management.
- Routing bank or customer confirmations through the company or its advisers instead of directly to the auditor.
- Not telling the auditor that an outside provider prepared the schedules.
- Forgetting to post final audit adjustments to the ledger, so next year's opening balances disagree.

Frequently Asked Questions
Will the auditor accept schedules prepared by an outside firm?
Yes, auditors routinely receive schedules prepared by outsourced accountants. They test the schedules in the same way as in-house work, and they will want to know who at the company reviewed and approved them.
Can NYBACS recommend an audit firm?
We can help you define the scope, request proposals and compare them, and we can share our experience of working with different firms. The decision and the engagement letter remain between your company and the auditor.
Does using a support provider reduce audit fees?
It often reduces the hours auditors spend waiting for or correcting information, which tends to lower fees and shorten timelines. The auditor's own required procedures do not shrink because the books were prepared by someone else.
Who attends meetings with the auditor?
Usually a company officer for planning and closing meetings, with the support provider attending to answer detailed questions. Routine fieldwork contact can sit with the support provider, subject to management's oversight.
