LYNKOS is the software for solar, heat pump, heating and HVAC contractors – one end-to-end system from the first inquiry to the final invoice. Sales, planning, back office and job site work on the same data: no duplicate entries, no data silos, no time-consuming handovers between teams. What LYNKOS covers: • PV planning with module layout, shading, string design and yield simulation • Heat load calculation and heat pump planning • Cooling load calculation and HVAC planning • Lead management and mobile site surveys • Quotes with digital signature • Project management, scheduling and crew planning • Time tracking, inventory and stock management • Invoicing, dunning and DATEV export • Service tickets, maintenance contracts and customer portal The result: fewer tool switches, faster quotes and a clean flow of information from sales to installation. One price for the entire core process: €79 per employee per month plus 19% VAT – no modules, no setup fee, 14-day money-back guarantee. Your data is stored GDPR-compliant in Frankfurt.
