Between A Bookkeeper And A CFO

At a certain stage, many growing companies find that a bookkeeper is no longer enough, and a full-time CFO feels like too much. COOs see that gap in every operating decision because the numbers stop keeping up. 

Here is how to tell when a company has reached that stage, and how fractional CFO support, such as the kind Optima Office offers, can help. 

Who Does What In Finance

A bookkeeper records what happened. The Controller keeps those records accurate and turns them into reliable reports. Forward-looking questions, such as what to price and whom to hire, belong to the CFO.

When nobody holds that forward role, the COO fills the gap with instinct.

Signs You Have Outgrown The Books

A few signals show that the financial function has fallen behind the business:

• Monthly reports explain what happened but not what to do next
• Pricing and hiring decisions rest on instinct
• Nobody can answer margin questions by customer or product
• Lenders, investors, or a future buyer will ask for more than the books provide

The Fractional Option

A fractional CFO is a senior finance executive who works with a company part-time. That brings forward-looking judgment without a full-time salary.

Optima Office Founder and CEO Jennifer Barnes argues that the best time to hire strategic financial leadership is before you need it, because companies that scale well build the infrastructure before problems arrive.

They offer fractional CFOs, Controllers, and outsourced accounting. Its team can start in as little as three to five days, which matters when decisions are already waiting on the numbers.

More than 300 companies, from startups to mid-market firms, work with Optima, and Inc. named it to the 2026 Inc. 5000 list of America’s fastest-growing private companies.

Bottom Line

Test your finance function with one question: what do the numbers say about next quarter? If the answer is a report on last quarter, the forward role is empty, and every pricing and hiring decision lands on the COO.
