What an interim CFO from Brimmer Company changes
An operator, not a consultant
We do not hand you a report and leave. We sit inside the process and make sure the filings get done.
Filings that land on time
Quarterly 10-Q and annual 10-K work is managed on a set rhythm, so deadlines stop sneaking up on the team.
Ready before the auditors arrive
We tighten internal controls and align with your external auditors so PCAOB audit issues get solved early.
Relief for an overloaded controller
We take work off your controller's plate and set a clear structure, so tired people stop making costly errors.
No full-time CFO overhead
You get CFO-level leadership part time, which fits companies too complex for bookkeeping and too early for a full-time hire.
Credibility with boards and investors
Board packages and audit committee answers are prepared, so leadership can present numbers with confidence.
Interim CFO support, built around SEC reporting
Brimmer Company works with small public companies in the $5M-$50M revenue range and with private companies that plan to go public in the next 12 to 24 months. These companies are too complex for basic bookkeeping, but a full-time CFO is more than the stage calls for.

Frequently asked questions
What does an interim CFO from Brimmer Company actually do?
We act as a fractional CFO and compliance operator. That means running 10-Q and 10-K filings, tightening the close cycle, preparing for PCAOB audits, and building board and investor reporting, rather than only giving advice.
How much does it cost?
Fees depend on scope. Every engagement is set out in a signed agreement covering scope of work, compensation, responsibilities and confidentiality. The 20-minute review is where we clarify what level of support your stage actually needs.
Are we the right size for this?
We focus on public companies with $5M-$50M in revenue and private companies planning to go public within 12 to 24 months. We are not a fit for private businesses under $2M in revenue with no public company or IPO plans.
Do you work with companies in our state?
Yes. Services are delivered remotely across the United States, by appointment. We do not take on clients outside the US.
Our filings are already late. Can you help?
Yes. Filing stabilization is a targeted service for companies where deadlines are slipping or audit pressure is building. We help get 10-Q and other SEC filings back to accurate, on-time and audit-ready.
Do you audit our financials?
No. We prepare companies for auditors and align with them, but we do not provide external audit or attest services. We also do not do basic bookkeeping or full-time CFO recruiting.
