If your school is one teacher with a handful of students, MMS is a perfectly reasonable tool for the price. But if you’re running a multi-teacher school with growth on your mind, you’re not comparing the same thing. MMS charges per teacher, doesn’t include CRM or marketing, and has meaningful billing limitations that require manual workarounds. The question isn’t what Opus1 costs. It’s what staying on a platform you’ve outgrown is costing you in time, errors, and missed growth.
