When Bookkeeping Isn’t Enough: How Controllers Fix Cash Flow Problems
You're generating consistent revenue, but something still feels off — cash flow isn't matching the numbers on paper. You’re not alone. Many million-dollar business owners hit this point and start asking: Why doesn’t my profit translate to cash in the bank?
In our first article (Trusting the Numbers: How Your Bookkeeper Impacts Cash Flow), we explored how bookkeepers lay the groundwork for cash flow through daily accuracy and reconciliation. But when the numbers get more complex, and the stakes are higher, accuracy becomes even more essential — and the need for reliable systems and forward-looking strategy increases. That’s where a financial controller comes in: to ensure accuracy isn't just maintained but used as the foundation for better forecasting, decision-making, and growth.
Not sure what a controller actually does? We break it down in The Role of Financial Controllers in Scaling Your Business and What Is a Strategic Financial Controller?.
A controller doesn’t just close the books. They connect the dots — between revenue and expenses, between your team’s processes and your cash flow, between what you think is happening and what’s actually showing up in your numbers.
Why Accuracy Is Everything — And What Happens When It’s Not
One client came to us with a profitable-looking P&L — but their cash flow told a different story. Revenue was recorded for jobs that hadn’t been matched with the corresponding costs. On paper, they looked cash-positive. In practice, they were coming up short every month.
This is how businesses get into trouble. They make projections based on incomplete data and spend money that’s already gone. Eventually, they’re asking the same questions I hear all the time:
“Why don’t I have any money in the bank?”
“How can I owe taxes if I didn’t make a profit?”
“Where did the cash go?”
The short answer? It went into transactions that weren’t recorded correctly — or weren’t recorded at all. The long answer? You need a controller to help clean that up and build a system that prevents it from happening again.
Controllers Look Forward, Not Just Back
Bookkeepers are often looking in the rearview mirror — entering what’s already happened. Controllers help you look forward. We take your goals and build the roadmap. And that means asking strategic questions:
What’s your exit plan?
How much do you want to sell the business for?
What kind of profit do you need to hit that number?
Once we know the target, we can shape the financials to help you get there. For example, one client came to us mid-year with a goal to expand — but their financial reports lumped all revenue into a single line item. We restructured the reporting by service category, helping them spot that their B2B work had far stronger margins than their direct-to-consumer stream. That clarity helped guide staffing and pricing decisions — and ultimately, better cash flow. We might adjust how your financial statements are presented, break things down by service line or revenue stream, or highlight key performance indicators (KPIs) that show where the money is really coming from.
Every Business Has Two Engines
Most businesses have two sides to their income:
Steady, everyday revenue (your “meat and potatoes”)
Specialty or high-margin work (the “big wins” that move the needle)
Controllers help you track both — and understand the margins behind each. Just like in the waste management industry, your day-to-day trash routes might keep the lights on, but it’s the roll-off services that bring in the big dollars.
Understanding that difference is key to managing — and growing — your cash flow.
It's Not Just the Numbers — It's the Process
Inaccuracy is usually a symptom. The root cause? Process.
AP didn’t enter an invoice
A vendor price increased but sales didn’t adjust the billing rate
No one told accounting that contract terms had changed
Each of these is a process issue — and every one affects your bottom line. We once uncovered a million-dollar miss when a vendor quietly raised their rates, but no one updated the billing terms to match. Sales didn’t flag the change, AP didn’t question the invoices, and no one told the controller. That breakdown in communication cost the company real money — and could have been avoided with stronger oversight and aligned processes.
Controllers aren’t just accountants. We’re pattern-finders, gap-closers, and accountability builders. We chase down the why behind a number being wrong, and we build systems to make sure it doesn’t happen again.
What a Controller Really Does for Your Business
At the end of the day, here’s what a controller brings to the table:
Accurate, trustworthy numbers
Visibility into what’s coming, not just what’s happened
Clear connections between operations, contracts, and financial results
Strategic support that aligns with your long-term goals
If you’re asking “where’s the cash?” more than once a quarter, it may be time to bring a controller onto your financial team.
In our next post, we’ll look at the CFO’s role — how they build on what your controller delivers and help guide big-picture decisions around cash flow, capital, and long-term growth.
