Nobody decides to run a business on spreadsheets. It happens one tab at a time. A quote calculator becomes the price list. A tracker becomes the job board. A reconciliation sheet becomes the thing the accountant waits for every month. Each one was the right call when it was made, and together they are now the operating system of the company.
That is fine, right up until it isn't. The hard part is noticing the moment it stops being fine, because nothing breaks on a particular Tuesday. It erodes. Here is how to tell.
Seven signs the spreadsheet is running you
One person knows how it works. If a specific person going on holiday makes a process stop, the process lives in their head, and the spreadsheet is just where they keep the numbers. That is a single point of failure dressed up as a file.
There is a cell nobody is allowed to touch. Every mature spreadsheet has one: a formula that someone fixed in 2023, that nobody fully understands, and that everyone has been told to leave alone. The business is depending on a thing it is afraid of.
You have a file called something like FINAL_v7 (2). Version drift means two people are, at some point, working from different truths. Usually you find out when a customer is quoted two prices, or an invoice goes out twice.
Someone re-types data from one place into another. From the enquiry form into the tracker, from the tracker into the invoice, from the invoice into the accounts. Every re-type is a chance for an error and an hour a week that nobody counts.
Reporting is a Monday-morning ritual. If the numbers for the management meeting are rebuilt by hand each week, the spreadsheet is not reporting; a person is reporting, with a spreadsheet as a calculator.
Things fall through gaps between files. A job that was quoted but never scheduled. An invoice that was raised but never chased. When the handoff between two spreadsheets is a person remembering to do it, some of them get forgotten.
You have started saying "the system" when you mean the spreadsheet. This one is subtle, but it is the clearest sign of all. The moment people treat a file as infrastructure, it needs to actually be infrastructure.
Why this happens to good businesses
It is worth saying plainly: this is not a sign of a badly run business. It is a sign of a growing one. Spreadsheets are the most flexible tool ever made, and flexible tools are exactly what you want when you are working out how you operate. The problem only arrives once you *have* worked it out and the process stops changing. At that point flexibility becomes risk, because anyone can change anything, and nothing stops them.
Off-the-shelf software is the usual next step, and sometimes it is the right one. If your process is a standard one, buy the standard tool and get on with your life. The trouble comes when your process is specific to how you compete, and the standard tool makes you bend to fit it. You end up with a subscription *and* a spreadsheet, which is the worst of both.
What to do about it, without a big-bang project
The instinct is to replace everything at once, which is how companies end up eighteen months into an ERP project with nothing to show for it. The better approach is to take the one spreadsheet that hurts the most, usually the one tied to money or to the thing you sell, and build it a proper home: a small system that does exactly what that spreadsheet does, with the rules enforced, the data in one place, and the handoffs automated.
Then you stop. You live with it for a month, see what changes, and only then decide what comes next. That is what we mean by Build & Iterate. The first stage is fixed-price, the second stage is quoted once you have seen the first, and you never commit to more than one at a time.
Where spreadsheets should stay
We are not against spreadsheets. They are brilliant at analysis, at one-off modelling, and at being the export that goes to the accountant. The goal is not a business with no spreadsheets. It is a business where the spreadsheets are outputs, not foundations, so that when the person who built them leaves, nothing falls over.
If you are not sure which side of the line you are on, that is exactly what the free mapping session is for. We look at how you run today and tell you straight which bits are worth building and which should stay as they are.
