Billing software for an electronics or home appliance shop

Serial-numbered batches of one, the maker's model code on every invoice, add-ons like installation and extended warranty on the bill, and dealer purchases off the MRP. NegoBill was built with these shops at the counter.

Updated 26 Sept 2026 · Applies to NegoBill V5

The day at an electronics shop

A television arrives as a batch of one with its serial number. The customer knows the model code from the advertisement. Installation is charged, an extended warranty is offered, and the dealer’s price is “MRP less 22%”. Two salesmen, one cashier, and the owner who alone should see the margin.

How NegoBill handles it

  • Product code: the maker’s code on the product, found by search, printed on the tax invoice.
  • Batches of one: each unit with its buying price, serial in the batch number, sold from that batch.
  • Add-ons on the product: installation, extended warranty, a stand — ticked per sale, each its own line.
  • Buying price from the dealer’s discount: type the MRP and the discount; the buying price and the minimum sale price follow (Business and above).
  • Permissions: salesmen bill, the cashier collects, only the owner sees buying prices and profit.
  • Job Cards: warranty and paid repairs with parts, advances and status.

Questions people ask

Can the invoice show the manufacturer's model code?

Yes. A product carries the maker's product code beside your own barcode; search finds it by either and the invoice prints it.

Can I add installation or a warranty on the same bill?

Yes. A product can carry add-on options such as installation or an extended warranty; ticking one on the sale adds its line under the product.

How do I handle a repair under warranty?

Job Cards (₹299 a year): intake with the serial number, status, parts, and a bill of zero or of the parts.
