A spreadsheet is not a database.
It is good for auto-calculations and analyzing a fixed data set. It is not built for daily record keeping.
One accidental keystroke in the wrong cell corrupts your data. It is no longer a source of truth.
A database is what powers every app. A proper repair tracking system keeps all your jobs visible and organized in a way a spreadsheet never can. A daily brief shows you exactly what needs attention that day, no more flicking through papers or digging through job envelopes to figure out what to work on next. It also keeps communication between service advisors and the watchmaker clear and documented.
If all you have is a spreadsheet, ask yourself: do you actually enjoy working in that sheet every single day?
