# Outsourced Accounting Services in the USA: How to Choose in 2026

Canonical: https://finbryn.com/us/guides/how-to-choose-outsourced-accounting-services-usa

Finbryn provides outsourced accounting for US businesses that have outgrown basic bookkeeping, with a maintained general ledger, a controller-level review and statements prepared for lenders or a board. To choose any provider, decide which level of work you need, then verify credentials, independence and exit terms. BLS reported a median wage of $83,680 for accountants and auditors in May 2025.

## Key takeaways

- "Accounting" covers four different levels of work, from monthly bookkeeping to an audit. Decide which level you're buying before you compare providers.

- Per the AICPA, a compilation gives no assurance, a review gives limited assurance and an audit gives high but not absolute assurance; the CPA must be independent for a review or an audit.

- If you expect an audit one day, ask now whether the firm keeping your books could also audit them. For SEC registrants, 17 CFR 210.2-01(c)(4)(i) says bookkeeping for an audit client impairs independence.

- Standing is free to check: CPAverify covers CPAs and accounting firms, and the AICPA's peer review public file shows enrollment for member firms.

- An in-house corporate controller has a national midpoint of $187,500 in Robert Half's 2027 guide, before benefits. Outsourced scopes are priced by entity count, volume and hours.

## Who provides outsourced accounting in the USA?

Searches for the top outsourced accounting firms put four different kinds of business under one label. There are practices owned by CPAs, which do bookkeeping, tax work and sometimes audits. There are national outsourced firms that run your close from a standard process. There are individual fractional controllers and CFOs who work on retainer. And there are staffing providers that supply a dedicated person. They overlap, but they aren't interchangeable, and a list that mixes them can't tell you which one fits.

This guide doesn't rank anyone. It shows what each level of accounting work is, who may issue what, and what you can verify before you sign. The first decision is the level of work you're buying, not the company, because the level decides whether you need a CPA at all.

"Accounting" as most owners use it means a maintained general ledger, a monthly close, someone reviewing the numbers and financial statements a lender will accept. Bookkeeping, covered in our [bookkeeping guide](/us/guides/how-to-choose-outsourced-bookkeeping-company), is the layer underneath. Everything above that layer is what the next section sorts out.

## The four levels of accounting work

The AICPA draws the lines this way (AICPA, September 30, 2023). A compilation is a CPA's report that provides no assurance; the CPA doesn't have to be independent, but any lack of independence must be stated in the report. A review requires an independent CPA, who performs inquiry and analytical procedures and gives limited assurance. An audit requires an independent CPA and gives high, but not absolute, assurance.

| Level | What you get | Assurance | Must the CPA be independent? |
| --- | --- | --- | --- |
| Bookkeeping and monthly close | Current books, reconciliations, management reports | None; no CPA report | Not applicable |
| Compilation | Financial statements with a CPA's report | None | No, but any lack of independence is stated |
| Review | Statements after inquiry and analytical procedures | Limited | Yes |
| Audit | Statements examined by an independent CPA | High, not absolute | Yes |

The standards behind the middle rows are the AICPA's Statements on Standards for Accounting and Review Services. AR-C 70 covers preparation of financial statements, AR-C 80 compilations and AR-C 90 reviews. If an engagement letter promises "financial statements" without naming one of these, ask which it is.

Finbryn works in the first row. It maintains the ledger, runs the close, applies controller-level review and prepares statements from the books, delivered without a CPA report. It doesn't issue compilation, review or audit reports.

## The independence trap: your bookkeeper may not be allowed to audit you

For companies that file with the SEC, the rule is explicit. Under 17 CFR 210.2-01(c)(4)(i), an accountant isn't independent if, during the audit and professional engagement period, it provides bookkeeping or other services related to the accounting records or financial statements of the audit client, unless it's reasonable to conclude the results won't be subject to audit procedures ([eCFR, current October 1, 2026](https://www.ecfr.gov/current/title-17/chapter-II/part-210/subpart-A/section-210.2-01)). Most small businesses aren't SEC registrants, and private-company independence rules differ, so don't read this as a ban that applies to you. Read it as a planning question.

If a lender, investor or buyer might ask for a review or audit within a few years, put one question to every candidate now: would your firm be able to issue that report on books you keep? If the answer is yes, ask what safeguards apply and who signs. If the answer is no, you know the audit needs a separate firm, and the books should be built so that firm can work from them: standard software, a clean trial balance and support kept for every material entry.

That is what audit support means in practice. It's workpapers, schedules and request lists prepared for the independent CPA, not a report. A provider that talks about audit services without saying who signs the report is leaving out the part that matters.

## Provider types compared

Cost cells use only figures traced to a source listed at the foot of this page. Where no public source exists, the cell says so.

| Provider type | What it costs | What you get | What to watch |
| --- | --- | --- | --- |
| In-house staff accountant, manager or controller | Midpoints in Robert Half's 2027 guide: staff accountant $76,500, accounting manager $115,000, corporate controller $187,500; BLS median for accountants and auditors $83,680 (May 2025); benefits on top | Daily access and institutional memory | One person's skills cap the function; no one reviews the reviewer |
| Practice owned by CPAs (local, regional or national) | Quoted; no public US source gives a range, so none is shown | Can issue compilation, review or audit reports if independent; may sign returns | Capacity; check license and peer review; ask who works on your file |
| National outsourced accounting firm | Bookkeeping starting prices published from $99 to $1,250 a month at the seven providers in our [cost index](/us/guides/us-bookkeeping-cost-index-2026), checked September 29 and 30, 2026; controller scopes appear as custom quotes at several | A standard close, a software stack and a team | Scope caps; whether any CPA reviews the work; closed platforms |
| Fractional controller or CFO (individual) | No public US survey; Finbryn's fractional CFO add-on starts at $1,500 a month | Senior judgment for a few days a month | Hours caps; nobody keeps the books going when that person is out |
| Finbryn | Essentials $249 and Growth $549 a month for bookkeeping; controller-level scopes quoted on Scale ([rate card](/us/pricing), September 29, 2026) | Ledger maintenance, close, controller-level review, statements | No CPA reports; remote delivery; see who it isn't for |

## Checks 1 to 4: standing, peer review, independence and the signature

**Check 1. License and standing.** Ask for the CPA's full name, state and firm. Verify while you're on the phone. CPAverify, run by NASBA, searches individual CPAs and accounting firms using licensing data sent by the state boards, and it shows enforcement and disciplinary markers ([NASBA, August 21, 2024](https://nasba.org/blog/2024/08/21/cpaverify-what-is-it-and-how-can-it-help/)). A national outsourced firm that isn't owned by CPAs won't appear as a firm. Then the question becomes who the reviewing accountant is and what that person signs.

**Check 2. Peer review.** The AICPA says almost every firm that performs accounting or auditing work is required to undergo a peer review. Its Peer Review Public File lists public accounting firms and their enrollment status, with the latest accepted documents for firms in certain AICPA sections or that chose to publish. Verify by searching the firm; if nothing is posted, ask for its latest report. Peer review concerns firms that issue accounting and auditing reports, so a firm that only keeps books may have none. Then checks 5 and 9 carry more weight.

**Check 3. Independence.** Put the question from the previous section to each candidate in writing. Verify the answer in the engagement letter, not on the call.

**Check 4. Who signs.** For any signature, ask for the name and credential, then look the person up as in check 1. Circular 230 section 10.3 lists who may practice before the IRS: attorneys, CPAs and enrolled agents, among a few narrower groups ([31 CFR 10.3](https://www.ecfr.gov/current/title-31/subtitle-A/part-10/subpart-A/section-10.3)). For return signing and representation, see our [tax preparation support guide](/us/guides/how-to-choose-tax-preparation-support-provider).

## Checks 5 to 8: scope, framework, close and systems

**Check 5. Scope in writing.** Accounting scopes differ more than prices do. Ask for a responsibility sheet that lists, for each item, who prepares, who reviews and who approves: general ledger maintenance, month-end close, accounts payable and receivable, payroll journals, fixed assets, sales tax, multi-entity consolidation and financial statements. Verify by comparing sheets from two providers. Gaps show up fast.

**Check 6. Reporting framework.** Ask which framework the statements will follow. A lender or investor may specify US GAAP, whose authoritative source is the FASB Accounting Standards Codification ([FASB](https://fasb.org/page/getarticle?uid=fasb_NewsRelease07-01-09Body_0228221200)). Cash-basis statements serve many purposes but aren't interchangeable with GAAP statements. Verify with a sample set that includes notes, and ask who writes the disclosures. A conversion to GAAP is a project of its own and should be priced separately.

**Check 7. Close calendar and variance review.** Ask which business day the books close and whether each close includes written commentary on variances. Verify with last quarter's package. Our [month-end close checklist](/us/guides/month-end-close-checklist) lists what a close should contain.

**Check 8. Systems.** Ask where the ledger lives and who owns the subscription: your QuickBooks Online, Xero, NetSuite or Sage Intacct account, in your name. The ownership test in check 1 of the [bookkeeping guide](/us/guides/how-to-choose-outsourced-bookkeeping-company) applies unchanged. Verify by asking the provider to show the user list on a screen share.

## Checks 9 to 12: control reports, the handoff, price and exit

**Check 9. Reports on controls.** For accounting services the useful report is often SOC 1. The AICPA describes it as an examination of controls at a service organization likely to be relevant to user entities' internal control over financial reporting, meant for those entities and the CPAs who audit their statements. If an auditor will test your books, ask whether the provider has a SOC 1 report, for which period, and whether audit firms have accepted it before. SOC 2 covers security and privacy criteria and answers a different question. Finbryn has no SOC report of either type today; its security page, checked October 8, 2026, lists SOC 2 Type I as planned.

**Check 10. The year-end handoff.** Ask to see a redacted handoff package from last year: trial balance, reconciliations, fixed asset schedule and a memo on unusual items. Finbryn's [year-end close and CPA handoff pack](/us/services/accounting-services/year-end-close-cpa-handoff-pack) describes its version. Confirm that your tax preparer or auditor will accept the format before you rely on it.

**Check 11. Price against the alternatives.** Ask for a quote built on entity count, monthly transactions, bank and card accounts and review hours. Verify with two quotes on identical inputs. Against an in-house hire, Robert Half's 2027 guide shows a $115,000 midpoint for an accounting manager and $187,500 for a corporate controller, before benefits. Finbryn's fractional CFO add-on starts at $1,500 a month.

**Check 12. The exit that matters.** In accounting, the exit pack is the ledger plus its support: year-end schedules, the documents behind adjusting entries, the fixed asset register and open items. Ask for these by name in the engagement letter. For practitioners such as attorneys, CPAs and enrolled agents, Circular 230 section 10.28 requires returning client records needed for tax compliance on request ([31 CFR 10.28](https://www.ecfr.gov/current/title-31/subtitle-A/part-10/subpart-B/section-10.28)). Other vendors need the clause in the contract. Our [switching guide](/us/guides/switching-bookkeepers-guide) has the full exit pack list.

## Where Finbryn fits, and who it isn't for

Finbryn's [accounting services](/us/services/accounting-services) cover a maintained general ledger, a monthly close, controller-level review and statements prepared from the books, inside a QuickBooks Online, Xero, NetSuite or Sage Intacct file you own. It's a national outsourced firm, one of the types in the comparison, and its bookkeeping tiers are on the [pricing page](/us/pricing). Who reviews the work, and where it's done, is answered on the [about](/us/about) and [security](/us/security) pages.

Finbryn is probably the wrong choice if:

- You need the same provider to issue a compilation, review or audit report. Finbryn doesn't issue them. It prepares the schedules and request lists the independent CPA will ask for.
- You want a practice owned by CPAs to sign your statements as a firm. Finbryn isn't one.
- You need a controller who works in your office. Delivery is remote.
- You need a SOC 1 report for your auditor this year. Finbryn has none.

## The 30-minute call: questions in order of consequence

Ask in this order, because the early answers decide whether the later questions matter.

1. Minutes 0 to 5, level: which of the four levels is this engagement, and what will you deliver and sign?
2. Minutes 5 to 10, standing: give me the name, state and firm of the CPA involved, and I'll look them up while we talk.
3. Minutes 10 to 15, independence: could your firm issue a review or audit report on these books, and what safeguards would apply?
4. Minutes 15 to 20, scope: walk me through the responsibility sheet. Who prepares, reviews and approves each item?
5. Minutes 20 to 25, evidence: send me your latest peer review report or SOC report, and a redacted year-end handoff package.
6. Minutes 25 to 30, price and exit: what is the fee for my entities, volume and hours, and where is the exit pack in the contract?

Afterwards, mark each of the twelve checks yes, no or unclear. Unclear counts as no until it's in writing. Do this for every provider, Finbryn included, and decide a day later.

## Frequently asked questions

**Q: Who provides outsourced accounting services in the USA?**

A: Four kinds of provider: practices owned by CPAs, national outsourced firms, individual fractional controllers or CFOs, and staffing providers. Compilation, review and audit reports come from CPAs under AICPA standards, so compare providers by the level of work, not the label. The twelve checks in this guide, last reviewed October 8, 2026, work on any of them, Finbryn included.

**Q: What is the difference between bookkeeping, accounting and a CPA?**

A: Bookkeeping records and reconciles transactions. Accounting adds the maintained ledger, the close, review and financial statements. CPA is a credential held by a person, checked through the state boards. It matters most when a report or return needs a signature. By the AICPA's descriptions (September 30, 2023), a compilation gives no assurance, a review gives limited assurance and an audit gives high but not absolute assurance.

**Q: Can the firm that does my accounting also audit me?**

A: For SEC registrants, generally not: 17 CFR 210.2-01(c)(4)(i) treats bookkeeping for an audit client as impairing the accountant's independence, unless the results won't be subject to audit procedures (eCFR, current October 1, 2026). Private-company rules differ. If an audit is likely, ask each candidate in writing whether it could issue the report on books it keeps.

**Q: How do I check that an accounting firm is legitimate?**

A: Look up the CPA and the firm on CPAverify, which draws on state board licensing data and shows disciplinary markers. Search the AICPA's Peer Review Public File for the firm's enrollment status. Ask for a SOC 1 report if an auditor will rely on the provider's controls. Then read the engagement letter for scope, exit terms and who signs. Every source for this answer was checked on October 8, 2026.

**Q: How much does outsourced accounting cost compared with hiring?**

A: Robert Half's 2027 Salary Guide shows national midpoints of $76,500 for a staff accountant, $115,000 for an accounting manager and $187,500 for a corporate controller, before benefits. National outsourced bookkeeping starting prices ran from $99 to $1,250 a month on September 29 and 30, 2026, and several of those providers quote controller scopes as custom. Finbryn's fractional CFO add-on starts at $1,500 a month.

**Q: Can an outsourced accounting firm prepare financial statements for my bank?**

A: Yes, as non-attest work. Finbryn prepares the profit and loss, balance sheet, cash flow statement and notes from your books, formatted for a lender. Whether the bank also wants a compilation, review or audit report is the bank's call, so ask for the requirement in writing. Those reports come from a CPA, and reviews and audits from an independent one (AICPA, September 30, 2023).
