Estimates to invoices in one tap

Build an estimate, get it approved, convert to a numbered invoice — no retyping.

VIN scan with free decode

Scan the door-jamb barcode and pull year, make, model, and engine from NHTSA — free, no key.

Parts-only tax, done right

Tax parts and not labor (or flip it per line). Discounts lower the taxable base proportionally.

Get paid on the spot

Your Venmo, Cash App, and Zelle print right on the invoice. Record cash, card, or check.

Schedule C at tax time

Gross receipts, sales tax collected, parts cost, and expenses by category — always current.

iCloud backup

For the stolen-van day. Back up to your own iCloud and restore everything on a new phone.
