Best Billing Software for Auto Parts Shops in India (2026)

Updated 18 October 2026 · By Ashok Sachdev · Competitor prices and features as listed on vendor pages in September and October 2026, excluding GST

A spare parts counter serves two buyers: walk-in two-wheeler and car owners, and mechanics who buy every day on credit and settle weekly. The catalogue is huge, many parts look alike, and a wrong part comes back the next morning. This guide compares the options on those needs.

What an auto parts shop needs from billing software

Which software fits which auto parts shop?

RichPOS: retail counters selling to mechanics on credit

Each mechanic or garage gets an account with dues, part payments and an optional credit limit; a bill that would cross the limit is not saved. Registered garages get B2B bills with their GSTIN, and the GSTR-1 report splits B2B and B2C for your CA. Low-stock alerts flag fast parts, and the reorder list groups items by supplier, ready to send on WhatsApp. Staff roles with discount limits stop counter staff from giving away margin. See credit limits for customers and purchase order management.

Vyapar: when you need offline billing, e-way bills or a free start

Vyapar lists offline billing, e-invoices and e-way bills (10 e-way bills a month on Silver, unlimited on Gold) and a free plan. It is the safer pick if your internet is unreliable. See RichPOS vs Vyapar.

Marg ERP: distributors and wholesalers

Marg suits B2B distribution with a desktop ERP; each extra user or company adds ₹3,000. See Marg alternatives.

GST on auto parts

Auto parts fall under many HSN headings, and the rate follows each part's HSN. Vehicle and inverter lead-acid batteries are at 18% from 22 September 2025 (Notification 9/2025-CT(Rate), Sch. II, S. No. 480; earlier 28%); see GST on batteries. For every other part, take the HSN from your distributor's invoice, check it in the HSN and GST rate finder and save it on the item once. Labour charged by a workshop is a service, not a sale of parts; ask your CA how to bill it.

Handling mechanic credit without losing money

1. Open an account for every mechanic and garage, with phone and GSTIN if registered.
2. Set a credit limit that matches one or two weeks of their buying.
3. Record every credit bill and every part payment against the account.
4. Take returns of unused parts as sales returns, so dues drop with the stock.
5. Send a WhatsApp statement every Saturday; follow up on dues older than 30 days. See how to recover udhaar.

Setting up an auto parts shop in RichPOS

1. Start the free trial and import your parts list (name with part number and model, brand, barcode, HSN, rate, MRP).
2. Set box-to-piece units and low-stock levels on fast parts.
3. Create mechanic and garage accounts with credit limits.
4. Give counter staff a role with a discount limit.
5. Reorder by supplier and receive purchase orders in parts.

Bottom line

An auto parts shop needs fast part search and tight mechanic credit more than anything else. Import your top 500 parts into the RichPOS free trial, set limits for your regular mechanics and run the counter for a week. Compare all options on the comparison page.
