Built for heat pump, solar, battery storage & EV charger installation businesses from 10-person operations to national energy suppliers. Master compliance, streamline operations, and scale without the operational chaos.

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.
You pay someone to keep these systems synchronized. 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 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.


Lead tracking, site surveys, multi-tech quoting, compliance docs, job scheduling, field team dispatch, customer portal, invoicing, service plans. Stop copying data between six different tools.
Handle solar + battery + heat pump + EV charger on a single quote. Track grant funding. Manage grid applications. Reduce compliance errors and the risk of failed inspections with tools that know the rules.
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.
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?".
One powerful platform designed to manage your jobs, teams, and finances, no matter how fast or how big you grow.

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.

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.
