Invoicing Software for Automotive Businesses
Estimate the repair, get customer approval, and bill parts and labor separately — then get paid before the vehicle leaves the shop. BillNama helps auto repair shops, body shops, and mobile mechanics across the U.S. apply the right Sales Tax and turn every repair order into a paid invoice.
What Is Invoicing Software for Automotive Businesses?
Automotive invoicing software turns a repair estimate into a customer-approved repair order, tracks parts, labor, and diagnostic fees against it, and bills the customer once the work is done. BillNama applies the correct Sales Tax automatically — rules for parts and labor vary by state, and BillNama keeps invoices compliant either way — and lets you send the invoice from the shop floor or a mobile unit.
Estimate vs. invoice: an estimate sets the scope and price before you touch the vehicle; an invoice is what you bill once the repair is complete. BillNama lets a customer approve an estimate and converts it into an invoice with one tap.
