Head to head
Checking sources…Payaca is solar, heat-pump, battery-storage, and ev-charger installers; clean-tech install businesses typically running 15–50 jobs per month in the uk and us. Here is where it beats us, where we beat it, and what each one actually costs.
Payaca has the most polished AI feature set of any vendor in this group (AI Agent Dave for natural-language business queries), a genuinely offline mobile app, and purpose-built clean-tech compliance workflows including MCS documentation and DNO tracking that generic FSM tools cannot match.
Highly vertical — solar/heat-pump businesses will love it, but a general electrician, plumber, or builder will find the product over-engineered for their workflow and will miss gas/electrical certificates, multi-trade job types, and broader UK-trade supplier integrations.
The mobile app lags behind the web version in functionality, which is a friction point for engineers completing work primarily from a phone.

Answer eight questions about your team, your trade and what's costing you money. We'll rank all 16 platforms for your situation and show three-year costs — and we'll tell you when a competitor is the better buy.
FAQ
Every competitor cell is read from that company's own public pages and dated. Where a vendor doesn't publish an answer we mark it not published rather than assuming a no — an absence of evidence isn't evidence of absence. Prices are shown in the currency the vendor actually bills in; we don't convert silently. Checking sources….
We compete with these companies, so treat this as our reading of the public facts, not a neutral audit. If something here is wrong or out of date — especially if it's your product — tell us and we'll correct it.
