Why contractors use it

How it works

Think of it as an estimate template for contractors that does the math for you.

  1. Add your business once. Name, logo, license number and phone.
  2. Build the estimate. Pick items from the starter list or type your own. Set qty, rate, markup, tax and deposit.
  3. Send it, then bill it. Share the PDF by text or email. When the job's done, tap Convert to invoice.

Questions

Is it really free?
Yes. Everything is free right now, with no job limit. No account, no card.
Do I need to make an account?
No. Open it and start writing. There's no email, password or card.
Where is my data kept?
On your phone, in your browser. We don't store your jobs or your customers. Use Backup to save a copy to a file, and keep it somewhere safe, because clearing your browser data erases the app's data too. On iPhone, add it to your Home Screen and back up regularly; Safari can clear site data you haven't opened in 7 days.
Does it work without signal?
It keeps working if your signal drops, once you've opened it. Add it to your home screen for one-tap access.
Can my customer pay me through the app?
Not yet. Your customer pays you the way they do now (check, cash, card reader, transfer), and you record the payment in the app so you always know what's still owed.
Is there a paid version?
Pro, $59.99 lifetime, is coming soon. It's a one-time price, not a subscription. When it arrives, Free keeps 5 jobs a month forever, and Pro adds unlimited jobs and a few extras.
