The Most Expensive Free Software You Own
2026-07-06Every business I walk into has one.
One spreadsheet. Or one process that lives inside one person's head. Or one aging system that everyone has agreed, without ever saying it out loud, to simply not look at too closely. It runs something that matters. Payroll, or bidding, or inventory, or the entire month end close. And there is exactly one person who truly understands it.
You know when that person is on vacation, because the whole office holds its breath.
That spreadsheet feels free. It came with the computer. Nobody sends you an invoice for it. And that is one of the most expensive lies in modern business, because the bill is very real. It just arrives in a currency nobody tracks.
Let me put numbers on the thing you already feel.
A 2024 study led by Professor Pak-Lok Poon found that 94% of business spreadsheets used in decision making contain errors (https://phys.org/news/2024-08-business-spreadsheets-critical-errors.html). Not 94% of the sloppy ones. 94% of the spreadsheets companies are actually using to make real choices about money and people. And the damage is not always small. Research into operational spreadsheets found that a single significant error costs an organization an average of $4,315, and that teams burn roughly 3.6 hours every week just hunting down and fixing mistakes, which adds up to more than 22 full workdays a year for every employee doing it (https://www.doss.com/research/spreadsheet-error-costs-operations-thousands).
Read that last part again. Twenty two working days. A month of someone's year, gone, spent correcting a tool that was supposed to save time.
I think about a construction company we came to know. Good business, real builders, the kind of people who can look at a job site and tell you what it will cost down to the board foot. But their bidding lived across a pile of disconnected spreadsheets. Every estimate meant opening five files, praying the numbers still matched, and hoping the version someone emailed last Tuesday was actually the current one. They were not bad at their jobs. They were great at their jobs, and slowly drowning in a system that could not keep pace with how good they had become.
That is the shape of the problem almost every time. The manual system is not there because anyone is lazy or foolish. It is there because it used to fit. The business was smaller. The spreadsheet was enough. Then you grew, quietly, the way healthy things grow, and one day the tool that used to carry you became the thing you carry.
Here is what makes aging systems so quietly dangerous. They do not fail loudly. A dead framework at least throws a security alert. A manual process just keeps opening. It boots up every morning and does most of its job, so it never trips the alarm that would make anyone stop and question it. The failure is not a crash. The failure is a slow leak. An error here, a lost hour there, a customer who got the wrong number, a decision made on data that was quietly wrong three columns over.
When we sit down with a company at Cause of a Kind, the first conversation is almost never about technology. It is about finding that one file, that one process, that one person everyone leans on, and asking the question nobody on the inside wants to say out loud. What happens to us if this breaks. The answer is usually a long silence, and that silence is the real diagnosis.
So here is the wisdom, and it costs you nothing to take.
Free is one of the most expensive words in your operation. The tools that feel free because you already own them are often charging you the most, because their cost hides inside your people's time, your error rate, and your exposure. You will never see a line item for it. You will only see it in the exhaustion of the person who keeps the spreadsheet alive, and in the quiet ceiling it places on how big you are allowed to get.
The goal is not to hate spreadsheets. They are a brilliant place to start. The goal is to notice the moment you outgrew one, because that moment almost always passes in silence, and the price of missing it only compounds.
If reading this made one specific file appear in your mind, or one specific person, or one process you have all silently agreed not to examine too closely, then you already have your answer.
You did not need me to tell you.
You just needed someone to say it out loud.
