What audit software costs a small firm
Almost nobody in this category publishes a price, so the comparison that matters is between licensing models rather than between numbers you were never shown.
Polara Enterprise costs $600 per engagement. Joining is free, there is no user count to license, and there is no annual minimum standing between your firm and the first file. Ten engagements cost $5,000, which saves $1,000 against buying them one at a time.
Audit software pricing for CPA firms is mostly unpublished, which means you cannot compare numbers nobody has agreed to show you. Compare the models instead. The licensing model decides whether a three-person practice can buy in at all. The figure is the smaller argument.
You know the shape of this search already. Type a vendor name and the word pricing into a search box, and the first page returns roundups that list employee scheduling software and a construction safety app as alternatives to an audit platform, ranked by whoever paid for the placement rather than by whoever has run an engagement. Nobody who has ever sent a PBC list wrote any of it.
What this category actually publishes
One thing is on the record, and it is checkable in a single click.
- Suralink publishes no price, stating that every company and team has different needs and inviting prospects to reach out. Source, checked 2026-07-30.
Fieldguide publishes no price of any kind. Not a range, not a starting figure, not a rate per engagement. Whatever figure you have seen attached to them arrived from a third party with no visibility into the contract, usually on a page that earns its living from the click rather than from being right. A partner comparing offers is benchmarking against somebody else’s guess.
The model is what excludes you, not the price
Per-user licensing charges a practice for having staff. That is backwards for audit work. Headcount is seasonal, the February roster is nothing like the July roster, and a license bought so the team survives busy season is carried at full freight through the quiet months when it earns nothing at all.
Annual minimums do the same damage from the other end. They ask a firm to commit against a book it has not won yet. You sign in the month cash is thinnest, for volume you will not see for nine more. A practice with six engagements clears the same floor as a practice with sixty, and the smaller one funds the difference out of partner draw.
Run it for three people and six engagements a year. Under either model the platform is a fixed cost that lands well before the first engagement letter is signed, which turns a software decision into a bet on next year’s pipeline. Six engagements at $600 each is $3,600 for the year, and every dollar of it arrives after a client has already committed to the work.
Four ways this category charges
Name the model before you argue about the number, because the number is downstream of it and a discount on the wrong model is still the wrong model. Every quote you get is one of these four, or a blend of two.
| Model | What it bills for | Who it suits | Where it breaks |
|---|---|---|---|
| Per-seat license | Named users, committed annually | Stable rosters at year-round utilization | Seasonal staffing. You pay in August for the busy season team |
| Per engagement | Each engagement you open | Uneven books, and books still being built | High volume, where a flat fee stops being the cheap line |
| Annual minimum | A committed floor, drawn down by usage | Firms that already know next year’s volume | A book that moves. The floor does not move with it |
| Quote only | Whatever the sales motion decides you can pay | Firms big enough to negotiate and to walk | Everyone else, benchmarking an offer they are not allowed to see |
The row that matters is the one describing your own book, not the one describing the firm the vendor wishes you were. A practice with predictable volume and a roster that holds all year is well served by an annual license, and paying by the engagement would cost it more over three years than the license does.
The roundups are written for ad revenue, so they optimize for the number of tools listed and the number of affiliate links carried rather than for whether any tool on the list could carry a real engagement. Treat the whole genre as unsourced until a figure comes with a date and a link.
Where the incumbents are the better buy
A demo would surface all three of these anyway. Better you read them now.
- You run financial statement audits at volume
- This platform is built around SOC 2 and adjacent attestation work. A practice whose revenue is tax, reviews and financial statement audits should buy a system designed for that engagement type, and the mature ones are genuinely good at it.
- You need a large integration estate
- Polara Enterprise does not pull evidence out of client systems. Evidence arrives through requests and the engagement vault, and somebody uploads it. If you want a platform that connects to twenty client environments and collects on a schedule, that gap is real and you will meet it in the first week rather than the first year.
- Your staff already know the tool
- Retraining a team mid-season costs more than most license lines do. If the current platform holds and the renewal is survivable, the switch belongs in a quiet quarter, not in February.
What the fee is, and what it is not
Free to join. No seats, no monthly fee, no annual commitment. An engagement bills once, at the point you open it, at $600. Ten cost $5,000 and stay valid for twelve months.
The fee is uniform. It is charged identically whatever the engagement covers and wherever the client came from. It does not move with your findings, your conclusions, or whether the report your firm issues is qualified. That last point matters more than the price does, because a platform fee that varied with the outcome would be an independence question,1 and you are the one who would answer it in peer review.2
The fee buys software, not introductions. What a firm charges its own client for the examination is a different question entirely, and what a SOC 2 auditor charges works through that side of the invoice. The practice model underneath the product was built with advisors out of Big Four practices, which is why the workpaper structure, the sampling and the sign-off chains look familiar rather than invented. Our independence and ethics policy states the rest of it in writing.
Polara Labs is not a CPA firm. SOC 2 examinations are performed by independent licensed U.S. CPA firms.3 The opinion, the sampling judgment and the issuance decision stay with the licensed firm on the engagement. The software records the work and the reviewer trail behind it, in the order it happened.
Four questions before you sign anything
- Ask what a slow quarter costs. A model that bills the same in a quarter with two engagements as in one with twelve has moved your seasonality risk onto your balance sheet.
- Ask what the next hire costs. If the answer is another license, the tool is charging you for growing, and it will charge you again when the hire leaves.
- Ask what leaving looks like. Workpapers you cannot export are workpapers you will rebuild, and you will rebuild them in the worst month of the year.
- Ask whether the fee ever tracks the outcome. It should not. Any fee that moves with a finding, a conclusion or a qualification is a question you will be answering later, under oath or under peer review.
None of this requires a call to find out. The price sits on the Polara Enterprise page where anyone can read it, and if you would rather watch it run against a live file than read about it, you can book a working session and bring one of your own.
