Owners pick dog size and a wash or full groom. This one is an example we made.
Scruffs lists dog size and a wash or full groom in the app. An owner picks both, sees the price and sends it. This one is an example we made.

They quote or invoice from the same app. No web inbox.
They send the package they picked. You can refine the price in the app after you see the dog.
No. They use the web page. Only the business needs the app.
Get the app. Add your sizes and packages. Make your page live and share the link.
