Choose a Denver accounting and advisory firm by matching its services to your needs, verifying credentials, and comparing written proposals—not by relying on a local address or broad service list. Confirm Colorado CPA status with the state, ask who will do the work and how your information will be handled, and get scope, fees, and deadlines in writing before work begins. If you need an audit, review, or other attest service, check the signing professional’s qualifications and ask for the firm’s latest peer-review information.
Start by defining the work you need
Before contacting firms, list the services you want and the outcome you expect. “Accounting and advisory” can cover different types of work; a firm’s general service menu does not establish that a particular team is suited to your engagement.

- Name each requested service and any deliverable you need.
- Identify your entity type and industry, and note any reporting or filing deadlines.
- Decide whether the work requires an audit, review, or other attestation engagement, rather than tax preparation or general accounting support.
Use the same description of your needs with every candidate. That makes proposals easier to compare and helps expose differences in what each firm includes.
Verify credentials and relevant experience
Check the credential that matters for the work
Colorado’s Board of Accountancy states, “The Colorado Board of Accountancy regulates certified public accountants (CPAs).” It also says it does not regulate accountants, public accountants, tax preparers, or enrolled agents. Ask what credential the person responsible for your work holds, then use the relevant credential source. For a CPA, check current status through the Colorado Board of Accountancy. A static directory or firm website cannot confirm live standing.

Ask about comparable engagements
Ask who will lead the work and what experience that person and the proposed team have with clients like you, your industry, and your entity type. Ask about recent continuing education relevant to the service. For an audit, review, or attestation engagement, separately ask whether the person signing the report is authorized for that work and has handled similar engagements. Authorization is not the same as practical experience or a fit for your particular needs.
Clarify scope, deliverables, and fees in writing
Get an engagement letter before work starts. It should make clear what the firm will do, what is outside scope, who is responsible, what you must provide, and what deliverables and deadlines apply. Ask whether any work will be outsourced and who remains accountable for it.

Ask for the fee and billing basis, along with the circumstances that could change the estimate. A proposal is difficult to compare if one firm’s fee covers a narrower scope or assumes more work from you. Confirm how additional requests, delays, or changed circumstances will be handled.

Assess communication and information security
Discuss how you will exchange documents and questions, what response times to expect, and how to reach the team throughout the year. Confirm who handles day-to-day questions and how the firm manages accuracy, timeliness, and confidentiality.

Ask how sensitive documents and personal information are protected, including when information is shared with outside providers. Do not assume that a polished website or a general assurance of confidentiality answers questions about the actual tools, access, or outsourcing arrangements used for your engagement.
For assurance work, examine peer-review information
If you are hiring a firm for audited or reviewed financial statements, ask for its most recent peer-review result. The AICPA peer-review public file provides enrollment status and, for firms in specified sections or firms that request public availability, accepted peer-review documents. Not every firm will have every document type available there.

The Colorado Society of CPAs describes peer review as a way to monitor accounting and auditing quality and identifies the AICPA program as the route for Colorado’s mandatory requirements. Treat peer-review information as one input about a firm’s accounting and auditing practice—not as a guarantee of future results or a substitute for checking the team’s qualifications and fit for your engagement. Ask the firm to explain its latest result and any relevant public-file documents.

Use a consistent checklist in interviews or proposal discussions:
- Which named services will the firm perform, and what is excluded?
- Who will lead the engagement, handle routine questions, and sign any report?
- What experience does the proposed team have with your industry and entity type?
- For attest work, is the signer authorized, and what comparable engagements have they handled?
- What deliverables, deadlines, and client responsibilities are included?
- Will work be outsourced, and how will sensitive information be protected?
- What are the fees, billing basis, and conditions that could change the estimate?
- How will you contact the team, and what response times should you expect?
- If assurance work is involved, can you review the firm’s latest peer-review information?
Compare answers for service fit, experience, credentials, scope and price, data handling, communication, and—where relevant—peer-review information. A Denver location or directory listing may help you find candidates, but neither establishes quality or suitability.
