IMEI Tracking from Purchase to Sale
IMEI tracking is the difference between "I think we sold it in March" and "Bill INV-0412, 14 March, Suresh, 98450…". In TripleBill every handset is entered by IMEI on the purchase bill, picked by IMEI on the sale, and can never be sold twice. Search any IMEI later and the whole history is there.

IMEIs in on the purchase bill
Turn on mobiles & electronics mode and tick "Track each unit by IMEI / serial number" on a phone model. When the supplier's stock arrives, enter the purchase bill and type or scan one IMEI per handset on that line. A USB or Bluetooth scanner types the number from the box label like a keyboard.
Only those units are now in stock. If a supplier invoices ten handsets and you scan nine, the shop holds nine. A purchase bill whose handsets have already been sold cannot be changed, so the history cannot be rewritten after the fact.
- IMEI per unit on the purchase bill
- Scanner-friendly IMEI fields
- Units on the shelf can be added from the IMEI page
- Purchase bills with sold units are locked
IMEIs out on the sale
On an invoice or at the POS, pick the model and choose the IMEI from the units in stock. With "IMEI required on sale" on, the bill cannot be saved without one. The unit turns Sold and disappears from the picker. Cancel or edit the bill and the IMEI goes back into stock.
The invoice, the thermal receipt and the shared invoice link print the IMEI and the date the warranty ends, from the warranty months set on the model (12 by default).
- In-stock IMEI picker on invoice and POS
- A unit can be sold only once
- IMEI and warranty end printed on the bill
- Cancel or edit puts the IMEI back
Search any IMEI
The IMEI / Serial numbers page lists every unit with its status — In stock, Sold, Returned or Defective. Open one and you see the supplier and purchase bill it came in on, the customer and invoice it went out on, and the warranty end. When a customer walks in with a phone and no bill, type the last digits and the answer is on screen in seconds.
A worked example
A shop buys 5 units of a ₹14,999 phone from its distributor and scans the five IMEIs on the purchase bill. Stock shows 5. On Saturday it sells two — the cashier picks IMEI …4417 and …4425 — each at ₹15,499 with a ₹499 tempered glass on the same bill. Stock now shows 3, and those two IMEIs cannot be picked again.
Eight months later a customer brings back …4425 with a charging fault. A search shows the bill date, the customer and "Warranty ends 12 Nov" — still under cover — and the counter books a repair job from that IMEI in one step.
Sample figures.
Reports
- Stock by IMEI — every unit on hand, by model
- IMEI sales register — who bought which unit
- Warranty ending — customers coming up to the end of cover
- Sales without IMEI — bills that slipped through, to fix later
Used phones and exchanges
Buying a used phone from a walk-in seller or taking one in exchange? Add the seller as a supplier, enter a purchase bill for the handset with its IMEI and the price you paid, and the phone is in stock like any other unit. When you sell it, the IMEI is picked on the bill and the history shows both the purchase and the sale.
For an exchange, bill the new phone and record the old one as a purchase from the same person; the difference is what they pay. Both IMEIs are on record if either phone comes back.
- Used phone bought on a purchase bill with its IMEI
- Exchange recorded as a sale plus a purchase
- Full history for both handsets
What it does not do (yet)
- A credit note (sales return) does not put the IMEI back into stock automatically — mark the unit Returned from its page
- Checking IMEIs against a stolen-phone register
- Separate fields for a second IMEI on dual-SIM phones — record the primary IMEI

Frequently asked questions
Can I scan IMEIs from the box?
Yes. IMEI fields accept a USB or Bluetooth barcode scanner, which types the number in. The Android app can also scan IMEIs.
What stops the same IMEI being sold twice?
Each IMEI is one unit in stock. Once it is on a sale it is no longer available to pick, until that sale is cancelled or edited.
I already have phones on the shelf. Do I need to re-enter a purchase bill?
No. Add the units on hand from the IMEI / Serial numbers page, then sell them like any other.
What if a sale is made on the phone without an IMEI?
It is accepted so the counter never stops, and it appears in the Sales without IMEI report so you can fix it.
Does it work for accessories?
Accessories do not need IMEIs. Leave tracking off on them and they bill like any item, on the same bill as the handset.
Which plan includes IMEI tracking?
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.
