How to Compare Technical Audit Proposals for Your SaaS

Imagine your SaaS company is considering a commitment to provide a customer with a scheduled report. Before agreeing, you want to understand what would need to change in the product and how the team would run and support that report after release.

You receive two technical audit proposals. One concentrates on source code and dependencies. The other includes architecture, delivery and operating practices. The second proposal covers more areas and costs more, but the descriptions do not yet tell you whether either assessment will examine the report workflow your decision depends on.

A wider list of topics can be useful. So can a focused review of a particular implementation. Before comparing the fees, ask each provider what evidence they will examine and what they expect that evidence to tell you.

The aim is to choose an assessment whose findings you can use for the decision in front of you. That requires knowing what will remain outside the report as well.

Write down the decision in ordinary business terms. In this example, the founder needs to decide whether to make a customer commitment, change its scope or investigate further before agreeing to it.

The answer may depend on how the report is generated and delivered, which parts of the product need to change, how releases are tested and who can investigate a failure after deployment. Your engineering leader can help identify which facts are already known and which ones need an independent look.

A different decision could require a different assessment. If you only need to examine a specific code change, a focused review may be enough. If the question includes how an operating product is released and supported, source code alone may leave part of that question unanswered.

Give both providers the same decision and ask them to explain what they would include, exclude and need from your team.

Return to the two proposals. The code-focused review may examine the files involved in producing the report, their dependencies and relevant tests. That can provide useful evidence about the implementation being inspected.

The broader assessment may also examine how a change reaches production and what information the team uses when a report fails to arrive. It will only answer those questions if the relevant systems, access and work are actually included. The word audit does not settle that for you.

Ask the providers to name the repositories, environments, integrations and operating practices they intend to examine. If they propose sampling, ask which flows or changes they would select and why those samples relate to your decision.

The purpose is not to demand the whole product in every engagement. A narrower assessment may be proportionate if it resolves the question you need answered.

Ask what the assessor will look at and how they will obtain the evidence. A proposal might include inspecting code and configuration, interviewing the people who operate the product, or performing an agreed test. Each can answer a different part of the question.

For example, an interview may tell you how the team says a release is performed. A deployment record can show what happened for a particular release. An authorized demonstration can show whether a person can perform a defined task under the conditions of that demonstration.

These observations are useful, but they do not all prove the same thing. Ask the provider how the report will distinguish something they observed from an explanation supplied by someone else, an inference and a question they could not verify.

Access matters here. Agree which accounts, environments and records are needed, who can view sensitive material and whether any testing of production systems is included and authorized. If access is unavailable, ask how that limitation will appear in the result.

A report can be accurate about the parts examined and still leave the decision unresolved. If an assessor reviews a sample of source code but cannot inspect the deployed report workflow, ask what can be concluded about that sample and what remains unknown about the product as it runs.

A missing record does not automatically prove that a control is absent. Equally, a clean result from a limited sample does not establish that the rest of the product is secure or that a future release will succeed.

Before choosing, ask each provider for an example of the deliverable. You should be able to see how a finding will describe the observed condition, the part of the product or business task it affects, the possible consequence and the evidence that is still missing.

Once the scopes are clear, compare the proposals over the same decision and period. Look at the work included, what the provider needs from your team and what each quote covers. If an important question is excluded, ask whether it can be added or whether it belongs to a separate assignment.

Include the time your team will need to prepare access, explain the product and respond to questions. You do not need to put an exact monetary value on every internal activity, but the people responsible should know what they are expected to provide.

Also ask about prior involvement in the system and any commercial interest in the recommended work. A provider offering to help implement a finding has a potential interest worth discussing. Ask how that interest and any disagreement about a finding will be disclosed.

A technical audit does not automatically include a penetration test, legal review or certification. If your decision requires one of those, ask for the relevant scope and qualified provider explicitly.

A security specialist may be needed for a specific security question. A legal adviser may need to assess contractual rights. A code review may be the right choice for a defined implementation. A broader assessment can be useful when the decision crosses code, delivery and operation, but its conclusions still depend on what was examined.

Neither proposal should promise to prove that the entire product has no vulnerabilities or that future changes will not fail. The report should say what was assessed and where further work may be needed.

Put the business decision beside each proposal. For the report example, identify which provider will inspect the relevant flow, what evidence they will use and what they cannot establish with the proposed access and time.

Ask for clarification or a revised scope where the answer is missing. Then compare the actual fees with the work and dependencies you understand. If neither proposal addresses the decision, you can narrow the question, request a different assessment or bring in a specialist.

A useful audit is one whose findings and limitations leave you better able to make the decision you commissioned it to support.
