Walk in with the rebate math already done.

WattGap puts a rebate calculator on your website and in your sales process. Homeowners see what they may qualify for before they ever call you.

30-day free trial. No credit card required.

How does WattGap work?

Two ways to use it. One subscription.

Turn your website into a closing tool

Embed a two-minute rebate calculator on your site. Homeowners enter their ZIP, income, and project type. They see every dollar they may qualify for. When they contact you, the financial case is already made.

Kitchen Table Mode

During in-home consultations, pull up the calculator and walk the homeowner through their rebate eligibility together. Seeing the numbers in real time converts hesitant buyers.

Show up to every appointment prepared

Website visitors who completed a rebate check already know the project is financially viable. You skip the education step and close faster.

Real numbers. Real savings.
