## What is Keystone?

Keystone is the all-in-one business manager for solo operators and small
  service teams — lawn care pros, dog walkers, daycare providers, house cleaners,
  mobile mechanics, handymen, and anyone else who bills by the job. Schedule,
  bill, and get paid without juggling five different apps.
  
  BUILT FOR THE WAY YOU ACTUALLY WORK

  • Clients & jobs — save every client with contact info, vehicles, children,
  pets, or properties. Book one-time or recurring jobs and watch them appear on
  your schedule automatically.
  • Invoices & estimates — send professional invoices and quotes in seconds.
  Clients can accept estimates and record payments right from their phone. Add
  your own payment QR codes so clients can pay you through the money-transfer
  apps you already use.
  • Recurring billing — set up weekly, biweekly, or monthly schedules once.
  Keystone generates the jobs and invoices on the right days, with per-visit or
  grouped billing cycles.
  • Time tracking & mileage — clock in and out on site, track driven miles
  automatically, and export clean tax reports at year end.
  • Client portal — invite your clients with a single code. They see upcoming
  jobs, past invoices, outstanding balances, and can message you directly. No
  more "did you get my email?"

  SPECIALIZED MODULES FOR YOUR INDUSTRY

  • Childcare / daycare — check kids in and out, log meals, naps, and medicine,
  with per-day billing and sibling discounts.
  • Lawn care — build multi-stop routes and log treatments per property.
  • Rental — manage inventory, bookings, and returns.
  • Dog walking, pet sitting, mobile detailing, mechanic, handyman, and more —
  the app adapts to your business type.
