How much does a SOC 2 auditor charge?

The auditor fee is the hardest line in a SOC 2 bill to see in advance. It goes to a licensed CPA firm, the only party allowed to examine your controls and report on them.¹ Platforms rarely break it out. This page does. For the whole bill, software included, read how much SOC 2 costs.

How a CPA firm builds the quote

Every quote starts with scoping. The firm asks what your product does, where it runs, how large the team is, which systems are in scope, and which criteria you want covered. Only then can it estimate hours, because the hours depend on all of those answers and on how your evidence is kept. A number offered before that conversation is a guess. A number still missing after it is a choice.

Rates

Firms bill partners, managers and staff at different rates. The partner signs and reviews. Staff do most of the testing, which is why a well prepared engagement leans on the lower rate hours. You will not negotiate the rates down much, since they are the firm’s business and are set before you ever call.

Hours

Hours are where your influence lives. They cover planning, walkthroughs with your team, testing each control, chasing missing evidence, writing the report and the partner’s review. On a small engagement the testing itself can be the shorter part. The chasing is what grows.

Five things that add auditor hours

None of these is about how secure you are. Each one is about how much work the firm has to do to reach an opinion, and a small team controls all five.

1. Report type. A Type 2 samples controls across months. A Type 1 does not. Starting with a Type 1 is the single biggest saving on a first audit.
2. Criteria in scope. Security is mandatory. Availability, Confidentiality, Processing Integrity and Privacy are optional,³ and each adds tests. The criteria guide explains what each one demands.
3. Evidence quality. A dated export mapped to a control is read once. An undated screenshot triggers a second request.
4. Response time. When a request sits for a week, the auditor has to reload the context later. That reload is billed.
5. System sprawl. More clouds, more vendors that touch customer data and more in scope tools each mean more to describe and test.

So the lowest cost audit is a prepared one. A founder who scopes tightly and hands over clean, dated evidence mostly pays for testing, which is the work the firm is there to do. One who does not pays for email.

Who invoices you

On the usual setup there are two parties and two bills. The platform sells the software. The CPA firm performs the examination under the AICPA attestation standards,² and carries the liability for what it signs. They differ in almost every way that matters to what you spend:

Two invoices also means two negotiations and two renewal dates. For a small team with no procurement function, that overhead is a real cost even before either number arrives.

Where the auditor fee sits on cybersoftware

Access to our preferred pricing program. The examination is performed by an independent partner auditor, a licensed U.S. CPA firm. The software does most of the work, so the auditor only has to verify evidence that arrives prepared. We negotiate the fee on your behalf. You prepare on the software, audit-ready starting at about a week, and the examination runs on the firm’s schedule after that.

No audit figure is listed on this site. We negotiate audit fees with independent licensed CPA firms on your behalf, and you see the price in your account before you book, Type 1 and Type 2 alike. Audits unlock after four paid months on monthly, or right away on yearly. A Type 2 also needs the 3-month observation window to finish first. How it works lays out the order.

Is a low auditor fee a warning sign?

It can be, and a CPA firm that does this work has said so plainly. Read the warning before you read our answer to it:

• Linford and Company warns buyers to be careful when a compliance tool has a partner audit firm with a set fee far below other bids, citing a case where one firm issued the same form report to every client with only the names changed. Source, checked 2026-07-30.

That risk is real, and we do not wave it away. A report stamped out from a template is worthless to your buyer, whatever it cost. But the problem it names is an empty examination, not a low number. Fees fall legitimately when a Type 1 is scoped to Security and the evidence arrives ready to test. They fall illegitimately when nobody tests anything.

You can tell the two apart yourself. Get the firm’s name before you sign the engagement letter. Look it up in the state board register.⁴ Read the test section of a sample report for procedures that name real systems. Is a low-priced SOC 2 audit legitimate? covers every check in order.

Questions that pull the fee into view

Send these to any vendor or firm before you sign anything. A clear written answer to each one tells you what you are really buying, and a vague answer tells you where the second invoice will come from.

• What is the auditor fee on its own, and which firm receives it?
• Is the first examination inside this quote, or billed after I commit?
• Which criteria and which report type does the fee assume?
• What happens to the fee in year two, when the work is a roll forward?
