Computer Shop Billing Software with Serial Numbers and Service Jobs

Mark high-value items — laptops, desktops, monitors, printers, graphics cards, SSDs, UPS units — as tracked by serial number, with their warranty months. Scan the serials on the supplier bill; at the sale, pick the serial from the units in stock. The invoice prints the serial and the date its warranty ends.

Cables, mice and pen drives do not need serials and bill like any item. Search any serial later and see which supplier bill it came on, which customer bought it and whether it is still under warranty. Mark a faulty unit Defective while it is with the brand.

• Serial per unit on purchase and sale
• Warranty end printed on the bill
• Serial search with full history
• Warranty-ending report

Build a quotation line by line — processor, motherboard, RAM, SSD, cabinet, PSU, monitor, assembly charge — with GST per line and a validity date. When a price changes, duplicate the quote, change the line and send version two. On yes, convert it to an invoice. If the machines go to the office before the bill, record a sale order and send them on a delivery challan.

For offices, the invoice carries their GSTIN and place of supply; IGST is applied for out-of-state buyers. Credit limits and part payments keep corporate dues in check.

• Quotations with validity
• Duplicate to revise
• Quotation → invoice in one click
• B2B invoices with buyer GSTIN

Book a repair with a job card: the device, its serial, the fault, an estimate and an advance. If you sold it, the serial brings up the sale and the warranty. The printed slip carries a QR to a status page for the customer; the job moves from Received to Ready, and Bill and deliver applies the advance. Parts used come out of stock on the bill.

The bulk price update grid changes sale, wholesale and purchase prices for many items at once after a distributor's price list arrives. Annual maintenance contracts can be billed as recurring invoices on a monthly or quarterly schedule.

Every bill posts to real double-entry books as you sell: sales, GST output tax, cash, bank and the customer ledger. Purchases do the same on the input side, so GSTR-1, GSTR-3B and the HSN summary are ready for any month and your accountant gets a trial balance that balances.

We would rather you know before you sign up:

• Assembling a PC from components as one finished item (no bill of materials) — bill the parts as lines
• AMC visit schedules — the AMC can be billed as a recurring invoice, visits are not tracked
• A credit note does not put a returned serial back into stock automatically — mark it Returned on the unit
