About SolarStack

Built for solar installers

SolarStack is the complete operating system for a solar installation business — combining a sales CRM, satellite site assessment, a market-rate quotation engine, inventory and costing, and installation project management into one connected workflow.

We started SolarStack because solar installers were running fast-growing businesses on spreadsheets, WhatsApp and guesswork. Quoting was slow, savings claims weren’t credible, and deals slipped between disconnected tools. SolarStack brings it all into one place.

Made by CrestSync

SolarStack is built and maintained by CrestSync, a software studio focused on practical tools for real businesses. We’re based in Pakistan and build for the local solar market first — real slab tariffs, net metering and PKR pricing — with the rigour to scale beyond it.
