Business CPA Letter
What a Business CPA Letter Is and when it’s used
Why organizations request a Business CPA Letter
A Business CPA Letter provides an independent, recognized validation of a company’s financial position or specific balances, reducing verification time for counterparties and supporting credit, underwriting, or compliance decisions.
Typical users and recipients of a CPA letter
The Business CPA Letter is used by multiple stakeholders who need third-party assurance about a firm's financial facts.
- Small and mid-size business owners requesting lender or investor verification of revenue and cash balances.
- Banks and credit unions assessing loan collateral, debt service capacity, or covenant compliance.
- Insurance underwriters and surety companies requiring confirmation of financial condition before issuance.
Understanding who prepares and who receives the letter helps ensure the correct format, level of detail, and authentication are applied.
Who can prepare and sign the letter
CPA or CPA Firm
A licensed certified public accountant or authorized representative of a CPA firm prepares and signs the letter. The signer should state their professional credentials, firm name, license state, and the scope of procedures performed to support the assertions.
Authorized Officer
Where a company provides an internal confirmation, an authorized officer (CEO, CFO, or controller) may produce a management letter; however, third parties generally prefer a CPA-signed letter for independent assurance.

Real-world examples of Business CPA Letter use
Lender Verification
A small business sought bank financing and provided financials to a CPA for a compilation letter
- The CPA confirmed cash and receivables as of month-end
- The lender accepted the letter and completed underwriting without an on-site audit, avoiding a two-week delay.
Insurance Underwriting
A contractor needed proof of revenue for surety bonding
- The CPA issued an agreed-upon procedures letter focusing on contract revenue
- The surety used the letter to price the bond and set collateral terms with minimal follow-up.

Frequently asked questions about Business CPA Letters
-
Can a CPA letter be e-signed?
Yes. Electronic signatures are enforceable under the ESIGN Act and UETA provided intent, consent, attribution, and retention are established. Confirm the recipient accepts e-signed letters and whether additional authentication or notary acknowledgement is required.
-
Is notarization required?
Not usually for standard CPA confirmation letters, but some recipients or state rules may request notarization or a notary acknowledgment. Verify recipient requirements before obtaining a notary or RON session.
-
What level of assurance is needed?
The letter should state whether it is a compilation, review, or opinion. Lenders commonly accept compilation or agreed-upon procedures letters; auditors’ opinions are higher assurance and less common for simple verifications.
-
How to handle sensitive data?
Limit PHI or PII in the letter. If sensitive health or medical billing data appear, use a HIPAA-compliant signing workflow and a business associate agreement where required.
-
Can the CPA decline to issue a letter?
Yes. A CPA may decline if the available records do not support requested assertions, or if issuing the letter would conflict with professional standards or independence rules.
-
How long is a letter valid?
Validity depends on the recipient; common practice is to accept letters dated within 30 to 90 days, but recipients may require a more recent date or periodic updates.
