How many ERP vendors should you evaluate before choosing?

Evaluate 3-5 vendors seriously. Fewer than 3 limits your ability to compare alternatives and negotiate pricing. More than 5 creates decision fatigue and delays your project. Start with a long list based on industry fit and company size, narrow to 3-5 through initial research and demos, then do a deep dive (RFP, scripted demo, references) on your top 2 before making a final decision.
