Most of what a finance team buys from an advisory firm isn’t an opinion. It’s hours. Somebody to finish the reconciliations, walk the controls, answer the auditors’ request list and write the memo nobody on staff has time for. The people who learned that work at the Big 4 leave every year, and some of them would rather keep doing it by the hour for a company that needs it than go back to a firm and another busy season.
KORE1 places them on W2 through our contract accounting staffing desk, part of the accounting and finance staffing practice. It runs on the same contract staffing model as every other seat we fill, so you manage the person. An advisory firm still fits when you need its formal opinion. We’ll get to that.
One house rule. Big 4 is a category on this page, and we don’t name firms.
What Do Big 4-Trained Contract Accountants Bring to Close, SOX and Audit Work?
Habits, mostly. A firm spends years teaching people to tie every number to a source and leave a trail the next reviewer can follow without asking. Then it makes them do it again in front of a manager. Over and over.
Month-end close
You see it first in the reconciliations. They get finished to a support, not to a plug, and review notes get cleared instead of argued with. That matters in week one. A trained senior also knows which accounts the auditors will pull in February, so those get the extra hour in December, before anyone has written a single request or booked a day of fieldwork.
SOX
This is where the training pays fastest. Someone who has tested controls knows the difference between a control that’s designed well and one that actually operated, can run a walkthrough without a script, and can tell a real deficiency from a paperwork gap. Section 404 of the Sarbanes-Oxley Act makes management assess those controls every year, and your contractor has sat on the other side of that table. Often for years. If the seat is compliance testing and not accounting, we also staff SOX and compliance analysts.
Audit support
Same skill, facing the other way. They’ve written the request list, so they can answer one. Cleaner schedules. Fewer second requests. Timing is its own question, and when to bring in contract accountants before audit season covers the window.
Where it falls short
Is every alum a good preparer? Not always. Someone who spent four years reviewing journal entries may never have posted one in your ERP. Ask. An ex-auditor can be brilliant at testing a reconciliation and slow at preparing it, so match the seat to what they actually did, which is the point of the four marks below. If the seat calls for a license holder on payroll, start with CPA staffing. Permanent audit roles run through auditor staffing.
What Do Big 4-Trained Contract Accountants Cost per Hour?
Every figure is a bill rate, what you pay through a staffing firm, at 40 hours a week. Three months is 13 weeks. Six months is 26.
| Role2 | Level | Bill range1 | Median | 3 months | 6 months |
|---|---|---|---|---|---|
| AccountantAccountant, modeled | Senior | $77 to $94 | $87 | $45,300 | $90,600 |

- 1Bill range is the 25th to 75th percentile, per hour. It includes payroll taxes, workers’ compensation, insurance and a modeled 24% employer burden.
- 2Every row is modeled from BLS OEWS May 2025 wages, SOC 13-2011 for accountants and auditors, 13-2051 for financial analysts and 11-3031 for controllers.
- 3Big 4 alumni are not split out in this version of the index. These are role rates, so a specific person can land anywhere in the range or outside it.
Read those as role rates, not alumni rates. The index can’t split Big 4 alumni yet, and we won’t print a number we can’t defend. When it can, the cell goes here. Until then the range is the market, and the way to price an actual person is to ask. Simple as that.
Two rows match on purpose. Not a typo. A senior accountant and a senior audit or SOX consultant both bill $77 to $94, median $87, because BLS counts accountants and auditors as one occupation. KORE1 has placed audit and SOX consultants, but most of those placements came from one engagement, so we withheld the observed cell instead of calling one client a market and printing it as a benchmark.
Level is where the money moves. A mid-level controller’s median is $127 and a senior controller’s is $165, about $39,600 apart over six months. Three months of a senior accountant runs about $45,300 against $66,100 for a mid-level controller, and that $20,800 buys a different job. Does your close need someone to run it, or someone to finish it? Those are different seats. If it’s a whole crew you’re short, look at the month-end close contract team. If the empty chair is the top one, that’s interim controller services.
Metro moves it too. A senior accountant models at a median $82 in Chicago and $109 in New York, which is $85,100 against $113,400 for six months. Same seat. Same work. Local desks are at accounting staffing in Chicago and accounting staffing in New York, and every level and metro we publish is in contract accountant bill rates for 2026.

How Do You Screen for Real Big 4 Experience?
A silver hallmark is a row of small punches, each struck after a different test. A résumé that says Big 4 has none. So test the claim four ways.
The résumé line
After the screen
Engagements
Which engagements did you actually work?
StruckNames the practice and the work. Assurance on public filers, testing on the revenue and payroll cycles, how many walkthroughs a season.
Not struckSays audit and can’t name a cycle. Or the years were really in tax or consulting, and the seat you need is SOX.
Level reached
Who reviewed your work, and whose did you review?
StruckRan fieldwork, reviewed staff and cleared a manager’s notes. Titles differ from firm to firm. Sign-offs don’t.
Not struckOne busy season as staff, then a bigger title at the next job.
Years
How many busy seasons, and how long ago?
StruckDates that add up, a season count, and what they’ve done since leaving. A controller seat wants years in industry on top.
Not struckA few years, no count. Old training isn’t the problem. Never having applied ASC 606 or ASC 842 is.
Verified
Who can confirm it?
StruckA person who managed them on an engagement takes the reference call. If the résumé says CPA, the license shows active on CPAverify.
Not struckOnly a peer can vouch, or the license lapsed and the résumé never heard about it.
Not every seat needs all four at full strength. A close backfill can live with two busy seasons and real preparer time. A SOX lead can’t. Chicago or anywhere else, the questions don’t change, and we’ll run them with you when we send a senior accountant or a controller, because a résumé can’t answer any of the four by itself.
Advisory-Firm Engagement or Hourly Contractors?
They aren’t priced the same way, so one number won’t settle it. Different shapes entirely. An engagement fee carries a team, review layers, the firm’s method and the firm’s name. An hourly contractor is simply the rate in the table times the hours worked, and in exchange for that simpler bill you supply the direction, the review and the method yourself.
| Question | Advisory firm | Hourly contractor |
|---|---|---|
| You buy | A scoped engagement and a team | One person’s hours |
| Directed by | The firm’s engagement manager | Your controller |
| Method | The firm’s templates | Yours |
| It ends when | The scope is delivered | You end the assignment |
We don’t publish advisory-firm rates, because no source we trust has them. There’s an easy test, though. Take your last engagement letter, divide the fee by the hours and set that beside the table above. Five minutes.
Then ask who’s going to run it. Hourly work with nobody to direct it just stalls, and that’s the honest case for the firm. We mean it. We’ve laid out a middle path for audit teams in internal audit co-sourcing vs outsourcing, where the chief audit executive keeps the plan and buys the hours.
When Is the Advisory Firm Still the Right Call?
More often than a staffing firm usually tells you. Four cases where we’d send you there ourselves.
Attest
You need a formal opinion
An audit opinion or attestation report comes from a licensed CPA firm, and no contractor can sign one.
Independence
Someone outside must conclude
Your board, lender or regulator wants the answer from a party with no seat on your team.
Dispute
The work may be challenged
A restatement or internal investigation usually calls for a firm your counsel can engage.
Direction
Nobody can direct the work
If no one on staff can review a SOX program, a contractor has nobody to answer to.
One rule cuts the other way. Under Section 10A of the Exchange Act, a firm that audits a public company generally can’t also keep its books or run its outsourced internal audit, so the seat your auditor is barred from is often the one a contractor fills. Worth knowing.
Check the one-year rule before you seat an alum
The same section stops a firm from auditing a public company if its CEO, controller, CFO, chief accounting officer or anyone in an equivalent position worked at that firm and took part in that company’s audit during the year before. SEC Rule 2-01 adds conditions for a former firm professional in an accounting role. So if the alum came off your own audit, stop and ask your audit committee before the start date. We’d treat an acting controller as covered, contract title or not. It’s your counsel’s call, not ours. This isn’t legal advice.
Boutique Staffing Firm or Large Firm, Who Manages the Relationship?
At a large firm you tend to get an account team and a process. At a boutique, the person who took your call is usually the person who calls back when something goes wrong. We’re the boutique, so weigh this accordingly. Fair warning.
“You want to work with a boutique firm, you’re going to get that warm type family feel. It costs a little bit more, but you get taken care of and you get transparency.”
Devin Hornick, Partner at KORE1, October 16, 2026
He said it costs a little more. It does. A large firm has real advantages too, including a wider bench, and if procurement only buys from a short approved vendor list, that may settle the question before anyone in finance reads this page.
Whoever you pick, ask how the bill rate gets built. Burden, insurance, sick pay, the benefits they carry. Devin’s test for any staffing partner is “a firm who’s willing to show you how they make their money and not hide anything.” Our version of that starts with what a 24% contractor burden covers.
Can You Keep a Big 4-Trained Contractor?
Yes. After 1,040 hours, which is 26 weeks at 40, a contractor can move to your payroll with no fee from KORE1. That’s the same point where the six-month column in the table ends, so the budget and the decision land on one date.
Plenty never get there, and that’s fine. The median KORE1 contract assignment runs 116 days, and 37.5% of contract-to-hire placements convert. A SOX cycle ends. A close catches up. When one of them turns out to be the person you’d keep, the door is open, and the math against a placement fee is in contract-to-hire vs direct hire cost, with the mechanics on contract-to-hire staffing.
What we commit to on contract is a short list. They show up on time, they get paid on Fridays, and conversion is free after 1,040 hours. That’s all of it. There’s no replacement guarantee on contract, so don’t build the plan around one.

Common Questions
Are Big 4-trained contract accountants cheaper than an advisory firm engagement?
For work your own team can direct, the structure favors the contractor, because you pay for one person’s hours and not a staffed engagement. We don’t publish advisory-firm rates, since no source we trust has them. To check it yourself, divide your last engagement fee by its hours and compare that with $77 to $94 an hour for a senior accountant.
What does a senior contract accountant cost?
A senior contract accountant bills $77 to $94 an hour nationally, median $87, about $45,300 for three months and $90,600 for six at 40 hours a week (KORE1 Contract Rate Index 2026-Q4, modeled). That’s the role rate. Big 4 alumni aren’t split out in this version, so a specific person can land anywhere in the range or outside it.
How much is a mid-level contract controller per hour?
$112 to $148 an hour nationally, median $127, which comes to about $66,100 for three months and $132,300 for six (KORE1 Contract Rate Index 2026-Q4, modeled). A senior controller runs $145 to $178, median $165.
Does a SOX or audit contractor bill more than a senior accountant?
Not in the index. A senior audit or SOX consultant models at the same $77 to $94 an hour, median $87, because BLS counts accountants and auditors as one occupation (KORE1 Contract Rate Index 2026-Q4, modeled). Our own audit and SOX placements came mostly from one engagement, so we withheld that observed cell.
Can a recent Big 4 alum be our contract controller?
Often yes, unless the alum worked on your audit at your audit firm within the past year and you’re a public company. Section 10A of the Exchange Act can then stop that firm from auditing you. Ask your audit committee and counsel before the start date. We’d treat an acting controller as covered, contract title or not.
