Commusoft is field service software for multi-trade businesses, from plumbing and HVAC to electrical, headquartered in London with US offices in Chicago. Its strength is service work: jobs, scheduling, job costing, service contracts, maintenance plans and asset history. Its website also markets a renewables offering, but permit tracking and solar design integrations aren't among the features it lists.
Payaca is built for solar, battery, heat pump and EV charger install businesses, around the installation project: permits, inspections, PTO and interconnection tracked on the job, design in Glow (limited release) or imported from OpenSolar, and multi-option proposals priced from that design. Here's how they compare for a US install business.
The short answer
If renewables projects are the business, choose Payaca: permits, design and proposals sit on one record from quote to commissioning. Commusoft is the better fit when reactive and planned service work is most of your volume.
- Payaca is best for clean energy install businesses running project-shaped work from lead through permitting to commissioning.
- Commusoft is best for multi-trade service businesses whose volume is reactive maintenance and planned service visits.
- Payaca publishes its pricing: Growth, the standard plan for established install businesses, is $1,724/month. Current plans and eligibility are on the pricing page. Commusoft sells per-license plans on 12-month contracts and does not publish prices on its US site; pricing comes after a call.

Questions
What's the main difference between Payaca and Commusoft?
Payaca is built for solar and clean energy install businesses, with permit tracking on the project, solar design in Payaca with Glow (limited release) plus OpenSolar imports, and multi-stage install pipelines. Commusoft is a multi-trade field service platform, strongest in service contracts, maintenance and job costing, that also markets to renewables businesses. If installation projects are most of your work, Payaca is built around them.
Does Commusoft handle solar permit tracking?
Permit tracking isn't one of the features Commusoft lists on its US site, and we found no permitting integration on its integrations page. Payaca tracks permits, inspections, PTO and utility interconnection on the project, with pipeline stages, custom fields and documents.
Which is better for residential solar installation?
Payaca is built for solar install businesses, with solar design and OpenSolar imports feeding the proposal, multi-stage install pipelines, and permit tracking. Commusoft suits multi-trade businesses whose revenue leans on service contracts and maintenance alongside installs.
Does Commusoft sell in the US?
Yes. Commusoft is headquartered in London, with US headquarters, sales and support in Chicago, and sells in the UK, US and Canada. Its plans are per-license on 12-month contracts, priced after a call.
