Is OpenSolar cheaper than Pylon?

Both OpenSolar and Pylon use custom pricing or have similar entry costs โ€” request quotes from both to compare apples-to-apples for your specific team size.

Can OpenSolar and Pylon integrate with QuickBooks?

OpenSolar does not have a native QuickBooks integration (Zapier workaround may exist). Pylon integrates with QuickBooks natively.

Do OpenSolar or Pylon offer a free trial?

OpenSolar: no free trial advertised; demo on request. Pylon: no free trial advertised; demo on request.

How long does OpenSolar vs Pylon take to implement?

OpenSolar: 1-3 weeks self-service onboarding. Pylon: 1-3 weeks self-service onboarding. Implementation length scales with pricing tier โ€” enterprise platforms ($250+/user/mo) require 3-6 months with dedicated admin time; mid-tier platforms typically reach operational status in 4-8 weeks with optional paid onboarding.

Can I migrate from OpenSolar to Pylon (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 โ€” 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.

OpenSolar vs Pylon: which has better customer support?

Both OpenSolar and Pylon offer email support across all tiers, with phone and live chat typically reserved for higher tiers. Response time SLAs vary by tier โ€” 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.
