Your software is the problem.

  • Payaca purple star

    If you're running on spreadsheets and free tools

    Your operations manager spends 15 hours per week copying data between systems. You rebuild quotes from scratch. You chase signatures on PDF proposals. Customers call asking "where's my installer?" because they have no visibility.

    If you're running a CRM, field service software, and a separate quoting tool

    You pay someone to keep these systems synchronised. Your CRM doesn't talk to your scheduling software. Your quoting tool doesn't understand clean tech compliance. Your field app shows appointments but not the technical specs installers need.

  • Payaca purple star

    Your software wasn't built for clean tech installations.

    Payaca is the all-in-one platform built specifically for businesses that install solar, heat pumps, batteries, and EV chargers. One system. One database. One source of truth.

One system. No more chaos.

    Actually know if you're making money

    Track job costs in real time. Manage supplier pricing. See project profitability during the work, not six months later when your accountant tells you what happened.

    Give customers a portal they'll actually use

    Let them view documents, book appointments, and make payments 24/7. Your customer service team can focus on real problems, not chasing signatures or answering "when's the engineer coming?".

And here's the proof.

We think the old way of working is broken. So do they. Real stories from businesses that switched to a single, modern system.

There was nobody we could see in the market that offered a tenth of what Payaca did within the renewable energy space. It's very rare that I get excited about a product that I don't actually build myself.

Payaca innovates more in a week than Commusoft did in years. So glad we made the jump, it was scary but the workflow, tracking, forecasting and automation are getting insane now.

Patrick Wheeler
MD at VitoEnergy

We've always found over the years that we've needed different sources for different reporting, which is why we came to Payaca originally. It's because we really want everything in one place, instead of a CRM system and seperate a sales system.

    Client portal

    Give homeowners and businesses a single place to review proposals, view certificates and handover packs, check appointment schedules, track job progress, and make payments online. Reduce your admin burden while offering transparency that actually sets you apart from competitors who still operate on phone calls and email attachments.

      Payaca mobile app updates

      Mobile app for field teams

      Your field teams work in demanding conditions, often with terrible signal. Give them an app that actually works. Clear view of daily schedules, required materials, site-specific plans, and technical specifications. Easy completion of task checklists and custom digital forms. Capture photos directly from site. The app works offline and syncs when signal returns. No excuses, just get the work done.
