Feature
Billing and Invoicing
Bill every part and every labor minute from the job card, and see sales, payments, and outstanding balances in one clear place.

Work that leaves the bay unbilled is money lost. It happens easily: a part is fitted in a hurry, an extra hour of labor is forgotten, and the bill is made from memory at the end.
With Piston OS, billing starts on the job card. Every part and every minute of work is recorded while the job happens. When the car is ready, the Sales Counter app turns the job card into the bill — complete, clear, and ready for payment.
You also get a clear money picture: sales, payments received, and what customers still owe, all in one place. No more searching through books to know where the business stands.
Common questions
Does Piston OS replace my accountant or accounting software?
No. Piston OS shows your sales, payments, and outstanding balances clearly, but it does not replace accounting software or your accountant.
Does it calculate VAT or taxes for me?
No. Piston OS does not calculate or file taxes.
