There is a spreadsheet in almost every growing company that quietly runs the business. Orders, stock, delivery dates, who owes what — all of it in a file that lives on one computer and is understood by one person.
Six years of the business in one file
The company we worked with had exactly that, and they were proud of it. It had been built up over six years and it did everything: it calculated prices, tracked the warehouse, reminded them about payments. It was, in a real sense, their business system.
It was also the reason nobody could take a day off.
It is not spreadsheet against system
When we looked closer, the risks were all in places nobody had time to think about. Two people had a copy of the file, and they were not the same file any more — someone had added a column on one and not the other. There was no history: when a number changed, nobody could say who changed it or when. And if that laptop had died, six years of pricing logic would have died with it, because the formulas were the documentation.
The mistake companies make here is imagining the choice is between "the spreadsheet" and "some huge expensive system". It is not. Most of the time it is one process that hurts the most, moved out first.
The right size of the first step
We took the warehouse and pricing part. It became a simple internal panel: orders, stock, prices, and a history of every change with a name and a time against it. The spreadsheet still exists — it is genuinely useful for the owner's own planning — but it is no longer the only place where the truth lives.
Nothing about the way the business works had to be relearned. The manager still does the same things in the same order. She just does them in a place that does not disappear with a laptop and does not depend on her being awake.
That is usually the right size of the first step: not a transformation, just the one thing that would hurt most to lose.
