The Solution

Payaca provided a centralised platform for quoting, scheduling, compliance documentation, and DNO applications. The integration with existing systems and automated compliance workflows transformed their operations.

“There was nobody we could see in the market that offered a tenth of what Payaca did within the renewable energy space. The compliance features alone have saved us countless hours.”

Andy Sellick

CTO, OVO Solar & Heating

VitoEnergy

Heat Pump Installer · 25 engineers

The Challenge

VitoEnergy was growing rapidly but their existing tools couldn't keep up. Quotes were taking too long, and the team was spending more time on admin than installations.

The Solution

Payaca's interactive proposals and customer portal transformed their sales process. The mobile app gave engineers everything they needed on site, while automated scheduling reduced office workload.

Guscott Heating Services

Heating & Renewables · 12 engineers

The Challenge

Running the business across multiple tools meant information was scattered everywhere. Reporting was a nightmare, and getting a clear picture of performance required hours of manual work.

The Solution

Payaca became the single source of truth for the entire business. All jobs, customers, invoices, and compliance docs in one place with real-time dashboards and automated reporting.
