THE USEFUL PART
Identify the licensed issuing firm and compare written proposals against one agreed brief. Size, brand, and platform partnerships alone do not settle fit.
Identify who will issue the report
An auditor’s brand, a consulting business, and a software platform can be different legal entities. Ask which licensed CPA firm signs the engagement and issues the opinion. Verify that entity’s license evidence through the relevant authority.
Our editorial approach separates these facts from marketing relationships. A logo in a platform’s partner directory tells you about a relationship; it does not replace a license check or explain your specific engagement.

Discuss your actual system
Our recommendation is to describe your service before asking for a fee. Explain your cloud environment, dependencies, team, customer commitments, and intended report users. Ask how the firm would scope the work and what it needs to learn before it can commit.
- Who will lead and perform the engagement?
- What experience does the team have with systems like ours?
- How will the proposed report address our intended users’ needs?
- How do evidence requests, questions, and escalations work?

Get the inclusions and dates in writing
Our suggested proposal checklist includes the report type, selected criteria, system boundaries, covered dates, fieldwork approach, report review, and expected delivery. Separate any readiness or advisory services from the examination itself.
Ask what happens if scope changes or evidence is late. A proposal should let you understand your obligations as well as the provider’s deliverables. Compare exclusions alongside the headline fee.

Make a decision you can explain
Our selection framework is a documented fit assessment: scope, relevant experience, working process, cost, and customer requirements. Keep questions and unresolved facts visible until you have an answer.
We do not assign numerical audit-quality scores. A sourced description and a candid account of what remains unknown give you a more useful basis for your own decision.
