Quick GST Billing App | Bill My Car

Every "simple billing app" demo looks quick until you bill a car with it. Then you discover there is no field for the chassis number, GST gets charged on the full sale price, and the invoice looks like it was made for selling shampoo. Simple is good; simple and correct for vehicles is the actual requirement.

What GST-compliant means for a used-car bill

What quick means, concretely

Quick is not fewer fields; it is entering each fact once. Buyer name, address, registration number, chassis, engine, price: typed one time, flowing into the invoice, the sale letter, the delivery note and Form 29 and 30 automatically. That is the difference between a two-minute bill and a forty-minute paperwork session, as we break down in how to make a car bill in 2 minutes.

Simple without being generic

The formats a car deal needs are fixed: GST invoice, non-GST buyer copy, amount in words, signatures. A vehicle billing app should give you those out of the box, not a blank template builder. If you are comparing against Tally, Zoho or Vyapar for this job, read Bill My Car vs generic billing software.

The rest of the deal rides along

Billing is one document of six or more per sale. The same entry should also produce the RTO paperwork and store everything, which is where a billing app grows into dealership management software. Bill My Car does the billing job described above, GST-correct and vehicle-native, in the browser on any device.

Frequently asked questions

What makes a billing app GST-compliant for used cars?

It must calculate GST on the margin (sale price minus purchase price) under Rule 32(5) of the CGST Rules for registered dealers, show the HSN code (8703 for cars), maintain a consecutive invoice series per financial year, and carry the dealer's GSTIN and place of supply. Charging GST on the full sale price is the classic non-compliant mistake.

Do unregistered dealers need a GST billing app?

Unregistered dealers issue non-GST bills, but they still need correct vehicle fields, a bill number sequence and clean records. A good app produces both formats from the same entry, so the day you register for GST nothing about your workflow changes.

How fast can billing actually get?

With buyer and vehicle details entered once, generating the invoice plus sale letter and RTO forms takes under two minutes in Bill My Car. Hand-writing or Word-editing the same set takes 25 to 40 minutes per sale.

Can I make a car bill on my phone with a billing app?

Yes. Bill My Car runs in the mobile browser: enter the deal, download the PDFs, share on WhatsApp, all from the yard.
