SOC 2 Type I vs Type II: What’s the Difference and Which Should You Start With?
Explains timelines, expectations, and how most companies approach Type I vs Type II in practice.
Introduction
Once you understand what SOC 2 requires, the next question usually comes quickly:
Do we need a Type I or a Type II?
This is one of the most common points of confusion. The terms sound technical, and it is not always clear how they apply in practice.
Choosing the right starting point matters. It affects your timeline, your costs, and how quickly you can move forward with customers.
The Short Answer
A Type I audit evaluates whether your controls are designed correctly at a specific point in time.
A Type II audit evaluates whether those controls are operating effectively over a period of time.
Most companies start with a Type I, then move to a Type II.
What Is a SOC 2 Type I?
A Type I audit looks at your controls at a single point in time.
The auditor reviews your systems, policies, and processes to determine whether they are properly designed to meet the Trust Services Criteria.
This means you need to have your controls in place, but you do not need to show months of history yet.
For example, if you have an access review process, the auditor will check that the process exists and is designed appropriately. They are not yet evaluating how consistently it has been followed over time.
A Type I is often the first step because it allows you to establish a baseline and demonstrate that your structure is in place.
What Is a SOC 2 Type II?
A Type II audit goes deeper.
Instead of looking at a single moment, it evaluates how your controls operate over a defined period, usually between three and twelve months.
The auditor will review evidence to confirm that your controls are not only in place, but are being followed consistently.
Using the same example, it is not enough to have an access review process. You need to show that reviews actually happened over time, that they were documented, and that any issues were addressed.
A Type II provides a much stronger signal to customers because it reflects real operational history.
Why the Difference Matters
The key difference between Type I and Type II is time and evidence.
Type I answers the question:
Do you have the right controls in place?
Type II answers the question:
Are those controls actually working over time?
From a customer’s perspective, Type II is more valuable because it demonstrates consistency, not just intent.
From a company’s perspective, Type II requires more preparation and discipline.
Which One Should You Start With?
For most companies, the path is straightforward.
Start with a Type I, then move to a Type II.
A Type I allows you to:
- Put your structure in place
- Go through an initial audit
- Identify any gaps early
Once your controls are in place and operating, you can begin the observation period required for a Type II.
Some companies choose to go directly to a Type II. This can make sense if:
- Customers already require it
- You have strong processes in place
- You can commit to the full audit timeline
However, skipping Type I can increase risk if your controls are not fully ready.
How Long Does Each One Take?
A Type I audit can usually be completed relatively quickly once your controls are in place.
A Type II takes longer because it includes an observation period. This period is often several months, during which you need to operate your controls consistently and collect evidence.
This is why planning ahead is important. If you need a Type II for a deal, you cannot start it at the last minute.
Common Misconceptions
One common misconception is that Type I is enough long term. In reality, most customers will eventually expect a Type II.
Another misconception is that Type II is simply a longer version of Type I. It is not just about time. It is about demonstrating consistent execution.
Some companies also believe they must complete both audits separately. While many follow that path, others move directly into a Type II if they are prepared.
Practical Takeaways
Type I evaluates whether your controls are designed correctly at a point in time.
Type II evaluates whether those controls are operating effectively over time.
Most companies start with a Type I and then progress to a Type II once they have built consistency.
Planning ahead is important because a Type II requires time to gather evidence.
Choosing the right approach depends on your customers, your timeline, and how mature your processes are.
What Comes Next
Now that you understand the difference between Type I and Type II, the next question becomes more operational:
What does the SOC 2 audit process actually look like from start to finish?
In the next article, we will walk through the audit process step by step so you know what to expect.
If you're preparing for SOC 2, starting with the right structure and building consistent processes early will make the transition from Type I to Type II much smoother.
