The Spreadsheet That Ran My Business for Two Years

I had a spreadsheet with every customer, every payment, every conversation. It was messy and manual and I complained about it constantly.

Then I moved everything to a proper tool. It took three weeks. And I lost something I did not expect.

The spreadsheet knew things I had forgotten. Notes about a customer's kid. A reminder that someone preferred calls over emails. A date that mattered. All of it was visible because I saw it every time I opened the sheet. The new tool was cleaner and I stopped seeing the details.

I have started keeping a small file of the human things that do not fit in any system. Not for the business. For me.

Have you ever moved something to a better tool and lost the thing that actually mattered? And did you notice right away or months later?
