Can I migrate from BigChange to Sera Systems (or vice versa)?
Yes, but expect data normalization work. Customer records and active jobs typically import cleanly via CSV. Historical job data, recurring service agreements, and custom pricebooks rarely transfer perfectly — most shops leave historical data in the source system as archival reference rather than migrating it. Budget 2-4 weeks of parallel operation between the two systems during the cutover.
BigChange vs Sera Systems: which has better customer support?

Response time SLAs vary by tier — entry-tier customers usually get 24-48 hour email response; enterprise customers get dedicated account managers with same-day response. Read recent G2 reviews specifically for support-quality signals before committing.
Which is better for solo contractors vs growing teams?
For solo contractors and 2-3 person teams, the lower-priced option (either) 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.
