What we learn building custom software
Every article comes out of a project we shipped — with the number, the decision, and what did not work. No second-hand theory.
Spreadsheet, off-the-shelf ERP or custom software: the answer is almost always more than one
A spreadsheet, an off-the-shelf ERP and custom software are not competing for the same spot: they sit in different layers of the same operation, and almost every healthy company runs all three at once. The expensive mistake is not picking the wrong one, it is changing layers when you did not have to: at a five-location gym chain the off-the-shelf ERP stayed as the source of every sale, and the custom system simply started reading from it every five minutes. The spreadsheet, in turn, stops working for three objective reasons, and none of them is size.
