Can I migrate from FastEST to Sera Systems (or vice versa)?

Which is better for solo contractors vs growing teams?

For solo contractors and 2-3 person teams, the lower-priced option (FastEST) typically wins on cost without sacrificing core features. For growing teams (5-15 employees), evaluate based on which platform's upper tiers include the features you'll need at your 12-18 month projected scale rather than buying for today's team size. For established 15+ employee operations, the depth of enterprise features (reporting, multi-location, marketing attribution) matters more than entry-tier price.
