Who’s Billy for?

Designed for estimating business-to-business services (consultancies, creative, digital agencies, freelance wizards), Billy is built for businesses who either don’t know how to estimate with confidence or have become frustrated with the way they’re currently estimating for work.

Billy is for freelancers, startups, micro or small businesses who want to:

  • stop blindly sticking to a day rate
  • stop overlooking costs when estimating
  • stop undercutting their own rate to win work
  • stop worrying about justifying project costs

If any of the above ring true, Billy will help you rethink how to estimate.
