Customer success stories

See how leading clean tech installers use Payaca to transform their operations, improve compliance, and accelerate growth.

OVO Solar & Heating

Energy Supplier · 12+ franchises

The Challenge

OVO Solar and Heating launched in early 2025 as a new venture within OVO Energy Group. Rather than building an in-house installation team, they chose a franchise model - partnering with regional installers across the UK. CTO Andy Sellick faced a critical decision: build an installer management platform internally, or find an external partner who truly understood the renewable energy space.

The Solution

Payaca provided a single platform for all franchises with API integrations for telephony, call recording, and Safety Culture. This gave OVO unified customer data across their entire network while avoiding what Andy estimated would have been 'multiple millions' in custom development costs.

“There was nobody we could see in the market that offered a tenth of what Payaca did within the renewable energy space.”

Guscott Heating Services

Heating & Renewables · 5+ engineers

The Challenge

When Guscott Heating Services pivoted toward renewable energy, their existing CRM lacked the renewable-specific functionality they needed. With no support for heat pumps, solar, or DNO applications, and poor pipeline management, Harland knew a change was essential - but previous difficult migrations made him hesitant.

The Solution

Payaca provided renewable-specific tools including DNO applications, heat pump forms, and Spruce integration, alongside fast quoting with templates, clear pipeline visibility, and automated follow-ups. The migration was the smoothest they'd experienced.
