Serial Number Tracking with Warranty Dates
Serial number tracking is how an electronics shop answers warranty questions without digging through bill books. TripleBill records the serial of every TV, washing machine, laptop, inverter or battery when it arrives, prints it with the warranty end date on the bill, and finds it again in seconds when the customer comes back.

Why serials matter beyond phones
Brands ask for the serial number on every warranty claim, and so does the customer's insurer. Appliances also get exchanged: if the serial on the replacement unit is not on record, the next claim becomes an argument. Tracking each unit makes the bill the single proof everyone accepts.
In TripleBill, serials and IMEIs run on the same engine — "Track each unit by IMEI / serial number" on the item — so a shop that sells phones and appliances keeps one list.
Warranty set per item, printed per unit
Give each item its warranty months — 12 for a mixer grinder, 24 for a refrigerator, 60 for an inverter battery if that is what the brand gives. A shop-wide default (12 months) covers new items. When the unit is sold, the bill prints the serial and the exact date its warranty ends, calculated from the sale date.
- Warranty months per item, with a default
- Serial and warranty end on invoice, receipt and share link
- Warranty-ending report for follow-ups
Units with a status you can trust
| Status | Meaning |
|---|---|
| In stock | Received on a purchase bill (or added as stock on hand) and not sold |
| Sold | On a sale; cannot be picked again until that sale is cancelled or edited |
| Returned | Came back from a customer; set from the unit's page |
| Defective | Kept aside for the brand or service centre; not offered for sale |
A worked example: a laptop and an inverter
A computer shop sells a laptop at ₹52,000 with a 12-month warranty and a 600 VA UPS at ₹3,400 with 24 months. Both are serial-tracked, so the cashier picks the two serials at billing. The invoice prints "SN 5CD3…, warranty ends 10 Nov 2027" for the laptop and the UPS serial with a 2028 date.
Eleven months later the warranty-ending report lists the laptop customer. The shop calls with an extended-warranty offer. When the UPS fails in month 15, a search by serial shows the bill, the date and that it is still covered; the unit is marked Defective while it goes to the service centre.

Repairs and service on the same record
Book a repair job from a serial and the device, customer and warranty fill in from the sale. The job slip carries a QR to a status page for the customer, and when the job is delivered it is billed with the advance applied. See Repair job cards for the full flow.
Which items to track by serial
Track the items where a warranty claim or a theft would cost you: laptops, desktops, monitors, printers, TVs, refrigerators, washing machines, air conditioners, inverters, batteries, CCTV recorders and power tools. Leave serial tracking off for cables, remotes, bulbs and accessories; they bill by quantity as usual.
A shop that is unsure can start with its ten most expensive models and add more later — turning serial tracking on for an item only changes how new stock of that item is received and sold.
- High-value and warranty items: track by serial
- Accessories and consumables: track by quantity
- Start with a few models and add more later
What it does not do (yet)
- A credit note does not put the serial back into stock automatically — mark it Returned on the unit page
- Brand warranty registration — TripleBill does not file claims with manufacturers
- Annual maintenance contracts (AMC) with visit schedules
How to track serial numbers and warranty in TripleBill
- 1
Mark the item
Switch on Mobiles & electronics in Settings, tick serial tracking on the item and enter its warranty months.
- 2
Receive with serials
On the supplier bill, type or scan the serial of each unit on its line so stock holds exactly those units.
- 3
Sell by serial
Pick the serial at billing; the invoice prints it with the warranty end date worked out from the sale date.
- 4
Look it up for a claim
Search the serial on the IMEI / Serial numbers page to see the bill, the customer and whether it is still covered.
Frequently asked questions
Is this the same as IMEI tracking?
Yes, the same feature: each unit is tracked by an IMEI or a serial number. Phones use the IMEI; appliances and computers use the serial.
Can different items have different warranty periods?
Yes. Set warranty months on each item; new items take the shop default of 12 months until you change it.
Can I add serials for stock I already have?
Yes. Add the units on hand from the IMEI / Serial numbers page without a purchase bill.
Does the customer get the serial on the bill?
Yes. The A4 invoice, the thermal receipt and the shared link all print the serial and the warranty end date.
Can I see whose warranty is about to end?
Yes. The warranty-ending report lists customers whose cover ends in the coming weeks.
Which plan includes serial tracking?
Serial and IMEI tracking, warranty and repair job cards are on the Pro plan (₹499/month, ₹4,999/year or ₹9,999 for 3 years). Every new business gets a 7-day free trial with everything unlocked.
