The problem
Two hours in Excel for every quote. Plus the phone calls.
You build quotes in Excel — 2 to 5 hours per project, formulas that break, prices double-checked by phone with the supplier, returns for incompatible parts, an invoice typed by hand into another program. And in the end you have no idea whether the client read the offer or not, until you call to ask.
Who it’s for
Who wins with Deviz Instalator

Solo installer or small HVACR company
You waste time with Excel quotes, calculation mistakes, and repeated phone calls for prices. You want a tool that does the quote, the invoice, and the order in one place.
-
Photovoltaic installation company
You handle complex projects with multiple suppliers and tight deadlines. You need an app that ties catalog, quote, scheduling, and invoicing together — no manual sync.
-
Regional distributor
You want to give your installer network a professional tool with your catalog built in — your installers become more efficient, you sell more.
-
Technical specialist issuing offers
You work for residential or commercial clients. You need quotes and invoices compliant with HG 907/2016, sent fast and looking professional.

AI intelligence
AI tuned to the trade
DI ships four AI features that cut errors and speed up your workflow:
-
Automatic compatibility check
The app verifies that the parts and equipment you picked are compatible with each other — eliminates wrong orders and costly returns.
-
Complementary product suggestions
Based on the configured job, the AI proposes accessories or materials that complete the quote — average order value goes up without extra effort.
-
Smart quote completion
Based on the type of job (boiler, photovoltaic system, heat pump), the app proposes a preset quote structure that you adjust as needed.
-
Automatic monthly reports
Summary of completed jobs, total quoted value, and offer-to-order conversion rate — without you building the report.

Why it’s different
Versus the alternatives

-
Accessible freemium model
The free version gives you the essentials. The PRO version unlocks advanced reports, extended integrations, and full AI — no implementation costs, no paid training.
-
Simple onboarding
You don't learn new software. You take the same steps you already know, just digital. First quotes can be created the same day you sign up.
-
Grows with you
Three usage tiers — beginner, intermediate, advanced — without forcing you into features you don't yet understand.
