Purpose-built for UK clean tech

Everything you need, in one system

Design the roof with Glow, quote it, run the install, file the MCS and DNO paperwork and get paid, in one system. Agent Dave, the AI built into Payaca, does the work you describe.

Agent Dave

Agent Dave, the AI built into Payaca. He does the work.

Ask Dave where you are losing jobs and he works it out from your account data. Ask him to chase quiet quotes and he builds the automation, shows you the full configuration and waits for you to switch it on. He edits your templates, shapes your fields and pipelines, and starts a solar design. He works as you, inside your permissions, and nothing goes to a customer without a person sending it.

Glow

Solar design inside the system that runs the job

Pin the roof. Glow pulls high-resolution imagery, finds the roof faces, lays the panels out from your own catalogue and builds an MCS compliant estimate, in the project your team already runs the job from.

Your own catalogue

MCS compliant estimate

Flow

A heat pump estimate before anyone books a survey

A customer fills in your enquiry form. Payaca pulls the EPC, runs the heat loss, sizes the heat pump and cylinder from your own appliance list, takes off the Boiler Upgrade Scheme grant and drafts an indicative estimate with the bill savings on it, ready for you to check and send.

Design tools

Design in Payaca, or in the tool you already use

Solar design is now native, with Glow. Heat pump estimates are native, with Flow. The EasyPV, Heatpunk, OpenSolar and Spruce integrations are unchanged and still work.

Stock & purchasing
