🔑 Key Features of the Auto Parts Store Management System

💡 Fast counter billing (POS). Search a part by part number, name, brand or vehicle, add it to the cart, pick the customer and payment mode, and print. The system splits GST into CGST + SGST for in-state customers and IGST for other states automatically.

📦 Parts inventory with vehicle compatibility. Each part carries part number, category, brand, vehicle make/model/year notes, HSN code, rack/bin location, purchase price, MRP, GST %, reorder level, a live stock badge and profit margin.

🔄 A reconcilable stock ledger. Every movement is recorded — purchases add stock, sales reduce it, and returns or adjustments correct it — so current stock always matches the ledger and never drifts.

📒 Customer and supplier ledgers. Receivables, payables, credit limits, part-payments and running balances are tracked automatically, with printable statements.

🧾 GST-ready invoicing and reports. Print A4 tax invoices or 3-inch/4-inch thermal receipts, and pull 14 reports including a GST summary for accountant support.

🔐 Role-based access. Admin, Manager and Cashier each see only what they are allowed to use, enforced on the server.

📦 What’s Inside the Auto Parts Store Management System

📊 Auto Parts Store Management System vs. Manual Spreadsheets vs. Paid Billing SaaS

For shops that want proper GST billing and stock control without paying every month per user, the Auto Parts Store Management System sits in the sweet spot.

👥 Who This Template Is For — and Who It’s Not For

✅ This template is built for:

• Retail and wholesale auto parts & spare-parts shops that need GST invoices.
• Garages with a parts counter selling to mechanics and walk-in customers.
• Small distributors who track supplier and customer credit ledgers.
• Owners who want to own their data on Google Drive instead of renting SaaS.

❌ This template is NOT for:

• Large chains needing barcode hardware integration and warehouse WMS.
• Businesses that require offline desktop billing with no internet.
• Teams needing statutory GST e-filing built in (this provides a GST summary for accountant support, not direct filing).

⚙️ How to Use the Auto Parts Store Management System

1. Create a new Google Apps Script project and paste the provided Code into Code.gs.
2. Add an HTML file named exactly Index and paste the Index code.
3. Run setup once to build the Google Sheets database with sample data.
4. Deploy as a web app (Execute as Me, access Anyone) and open the URL.
5. Sign in with the default Admin login, then set your store profile and GSTIN in Settings.

💼 Real-World Use Cases

Ramesh runs a spare-parts counter in Pune. He bills walk-in customers and mechanics on the POS screen, prints a 3-inch thermal receipt, and the stock reduces automatically — no more end-of-day counting mismatches.

Anita supplies parts to three garages on credit. She uses customer ledgers and credit limits to track dues, records receipts against invoices, and pulls the Customer Outstanding report every week.

A two-branch distributor gives the Cashier role to counter staff and keeps purchase prices and supplier settings for the Manager and Admin, so pricing stays protected while billing stays fast.

❓ Frequently Asked Questions

What is the Auto Parts Store Management System?

The Auto Parts Store Management System is a Google Apps Script web app that handles GST counter billing, parts inventory with vehicle compatibility, purchases, returns, payments, customer and supplier ledgers, and 14 reports for an auto spare-parts shop.

How long does setup take?

Setup takes under 15 minutes: paste the code into a Google Apps Script project, name the HTML file Index, run setup once, and deploy as a web app. A step-by-step deployment video is included.

Does it handle GST correctly?

Yes. The Auto Parts Store Management System splits GST into CGST + SGST for in-state customers and IGST for inter-state customers based on the customer’s state, and uses HSN codes and configurable GST rates.

How does this compare to Vyapar or Zoho Inventory?

Unlike monthly SaaS, the Auto Parts Store Management System is a one-time purchase you own on your own Google Drive, with no per-user fees — while still giving GST billing, stock ledgers and role-based multi-user access.

Can multiple staff use it at the same time?

Yes. Share the web app link and each person signs in with their own Admin, Manager or Cashier account; the system hides and disables actions each role is not allowed to use.

Will my stock stay accurate?

Yes. Every movement is written to a stock ledger, so purchases add, sales reduce, and returns or adjustments correct stock — current stock always reconciles with the ledger.
