Choosing an ERP is one of the highest-stakes technology decisions a growing business makes, mostly because it's expensive to reverse. A rushed selection, made under deadline pressure, tends to optimize for the platform that's easiest to buy rather than the one that will still fit in three years.
The most useful early question isn't "which ERP has the most features," but "which of our processes are non-negotiable, and which are we willing to adapt to fit the software." Every ERP platform has an opinion about how work should flow; fighting that opinion on core processes is where most expensive customizations come from.
Data migration and integration are usually underestimated in the planning phase. The systems your ERP needs to talk to — your e-commerce platform, your existing CRM, your accounting tool — determine a large share of the total implementation cost, often more than the software license itself.
Timeline pressure is the single biggest predictor of a bad ERP choice. Businesses that commit to a platform because "we need something live by next quarter" are the ones most likely to be migrating again within two years. A structured evaluation, even a compressed one, pays for itself many times over.
