Where Is My Money Actually Going? A CFO's Method for Finding the Leaks

Almost every founder I work with can tell me what they sell. Very few can tell me where the money goes after it comes in. Revenue feels visible. Costs feel like fog. So the account stays thinner than it should, and nobody can quite say why.

Here is the part most owners get wrong: the money is not vanishing. It is leaking, slowly and predictably, through a handful of lines you stopped looking at. Finding those leaks is not a once-a-year cleanup. It is a monthly habit. Let me walk you through how I help founders build it.

"Why does my revenue grow but my bank account doesn't?"

This is the question under the question. Sales are up, the team is busy, and yet the cushion never gets thicker. When I dig in, the cause is almost always the same: the founder is watching the top line and ignoring the lines below it.

Money keeps coming in, and money keeps going out, but the going-out side has no owner and no rhythm. Costs drift up a little each month. No single increase is alarming. Together they eat the entire gain from growth. A marketing agency I worked with had grown revenue noticeably over a year while take-home profit stayed flat. Nothing dramatic happened. A dozen small lines each crept up, and the growth quietly paid for them.

You cannot fix what you do not see. So the first move is making the spend visible.

"How do I even read my own expenses?"

You read them by making them readable first. Most founder books are a mess, not because anyone is careless, but because nobody decided where things go and stuck to it. The same cost lands in three different categories across three months. Software shows up under marketing one month and under operations the next. When categories wander, every report lies a little.

Consistent categorization is the unglamorous foundation of cost control. Pick a structure. Every recurring cost has one home and stays there. Direct costs of delivering your product or service go in one place. The cost of running the company goes in another. Owner pay and taxes sit apart from both.

Once the categories hold still, patterns appear. You can finally compare this month to last month and trust the comparison. A construction company I worked with could not tell whether equipment costs were rising or just bouncing around. After three months of consistent categorization, the trend was obvious and the conversation got easy. The numbers had not changed. The clarity had.

"Which expenses do founders always underestimate?"

After enough of these reviews, the same culprits show up across every industry. Three lines run higher than the founder's mental model almost every time.

The first is subscriptions and software. Tools get added for a trial, a project, a single person's preference, and then nobody cancels them. They renew silently. I have sat with founders who discovered a meaningful slice of monthly spend going to tools no one on the team could even name, let alone use. That is not a pricing problem. That is an ownership problem.

The second is fulfillment and delivery. Whatever it costs to get your product or service to the customer, it usually costs more than the plan assumed. A beverage brand I worked with had modeled direct delivery at one cost and was actually paying noticeably more once handling, breakage, and returns were counted honestly. The model was optimistic. Reality sent an invoice.

The third is contractor and freelance spend. This one creeps. You bring someone on for a specific task, the task expands, the relationship lingers, and a month later you are paying ongoing money for help nobody formally decided to keep. Contractor creep hides because each individual payment feels justified. Add them up and you have a salary you never approved.

"Are there subscriptions or tools nobody owns?"

Almost certainly yes, and this question deserves its own answer because it is the fastest win available to most founders.

Pull every recurring charge. For each one, ask a blunt question: who owns this, and what would break if we cancelled it tomorrow? If nobody can name the owner, that is your answer. An ecommerce company I worked with ran this exercise once and cut a surprising share of its tooling spend in an afternoon, with zero impact on operations. The tools were not serving the business. They were just renewing.

Do this quarterly. Subscriptions are a tide. They come back in if you stop watching.

"Before I approve a new expense, what should I check?"

Founders ask me this constantly, usually right before they commit to something. The answer is a short mental checklist you can run in under a minute.

Check what this spend replaces or adds. Is it a new cost or a swap for something you can now cancel? Check who owns it after today, because an expense with no owner becomes a leak. Check whether it scales with revenue or sits fixed regardless of sales, since fixed costs are the ones that hurt in a slow month. And check where it lands in your categories, so the next review counts it correctly.

None of this requires a finance background. It requires the discipline to pause for sixty seconds before the money leaves. Most overspending is not one bad decision. It is a hundred small decisions nobody paused on.

"How do I actually reduce costs without gutting the business?"

Here is the reframe that changes everything: cutting costs is not an event. It is a rhythm.

Founders tend to treat cost control as a panic response. Cash gets tight, so they slash. They cancel tools, freeze hiring, squeeze vendors, all in a frantic week. Then the pressure eases and the slow creep starts again. Six months later they are back where they started, planning the next big cut.

The owners who actually keep costs in line do something far less dramatic. They look at the same clean expense report every month. Same categories, same order, same questions. They are not hunting for a giant cut. They are catching small drift before it compounds. A line ticks up, they ask why, and they handle it while it is small. The review takes under an hour. The result is a business that never needs the panic cut, because the leaks never get big enough to matter.

A software startup I worked with adopted this monthly review and stopped having cost crises entirely. They were not spending less because they found one huge saving. They were spending less because nothing surprised them anymore.

The real lesson

Where your money goes is not a mystery. It is just unwatched. Consistent categories make the spend visible. A monthly review makes the drift catchable. A sixty-second check before each new expense keeps the leaks from starting.

You do not need to be afraid of your own costs. You need a structure that shows them to you and a habit of looking. Build that rhythm, and the question stops being "where is my money going" and starts being "what do I want it to do next."
