TripleBill for Mobile shop
Mobile Shop Billing Software with IMEI Tracking
A mobile shop sells three different things over one counter: handsets that must be traced by IMEI, accessories that sell by the dozen, and repairs that come back days later. TripleBill handles all three in one app, with GST invoices and the accounts kept for you.

What gets in the way
- A customer comes back with a phone and nobody can say which bill it was sold on
- The same IMEI gets typed on two bills, or a handset that was never received shows as sold
- Warranty disputes because the purchase date and model are not on the bill
- Repairs tracked in a notebook, customers calling every day to ask if the phone is ready
- Accessories, recharges and repairs mixed up in one cash drawer with no clear profit
Every handset traced by IMEI, from supplier to customer
Switch on mobiles & electronics mode and mark a phone model as tracked by IMEI or serial. When the stock arrives you enter or scan each IMEI on the purchase bill, so the shop only ever holds units it actually received.
At the counter, the invoice lets you pick from the IMEIs in stock for that model. A unit cannot be sold twice, a purchase bill whose handsets have already been sold cannot be changed, and cancelling or editing a sale puts the IMEI back into stock. Search any IMEI later and you see where it came from, who bought it and on which bill.
- IMEI / serial entry on purchase bills
- In-stock IMEI picker on the invoice
- IMEI search with full history
- Stock-by-IMEI and IMEI sales register reports
Warranty printed where the customer will look for it
Give each model its warranty period once. Every invoice, thermal receipt and shared invoice link then prints the IMEI and the date the warranty ends, so a warranty claim starts from the bill instead of an argument.
The warranty-ending report shows which customers are coming up to the end of cover — a natural moment to offer an extended plan or an upgrade.
- IMEI and warranty end on the PDF, receipt and share link
- Warranty-ending report
- Brand and model on every item
Repair job cards the customer can follow
Book a repair with a job card: type the IMEI and the device and warranty fill in from your records. The job moves through clear steps — received, diagnosing, waiting for parts, in repair, ready, delivered — and the printed slip carries a QR code that opens a public status page for the customer.
Send the update on WhatsApp from your own number. When the customer collects, bill the job and the advance they paid is applied automatically.
- Job card with device, fault and estimate
- A5 two-copy or 80 mm slip with QR
- Public status page per job
- Bill-and-deliver with the advance applied
Accessories at counter speed
Covers, chargers and earphones do not need IMEIs. Bill them from the POS with barcode scanning or photo tiles, alongside a handset on the same bill, and take cash, UPI or a split payment. Low-stock alerts tell you when the fast-moving accessories need reordering.
- Barcode and tap-to-add billing
- Split cash / UPI / card payments
- Low-stock alerts and reorder levels
- Barcode labels for loose accessories
Mobile shop: what you need and how TripleBill does it
| What a mobile shop needs | How TripleBill handles it |
|---|---|
| IMEI on every handset sold | IMEI entered on the purchase bill, picked on the invoice, printed on the bill |
| No duplicate or phantom IMEIs | A unit can only be sold once and only if it was received |
| Warranty proof | Warranty end date printed with the IMEI; warranty-ending report |
| Repairs | Job cards with status steps, QR slip and a customer status page |
| Accessories | POS billing with barcodes, split payments and low-stock alerts |
| GST | CGST / SGST or IGST from the place of supply, HSN per line, GSTR-1 and 3B figures |
GST and the books, done underneath
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.

Frequently asked questions
Can I scan IMEIs with a barcode scanner?
Yes. IMEI fields accept a USB or Bluetooth barcode scanner, which types the number in like a keyboard, so you can scan the box label on the purchase bill and on the invoice.
What stops the same IMEI being sold twice?
Each IMEI is a unit in stock. Once it is on a sale it is no longer available to pick. Cancelling or editing that sale releases it back into stock, and a purchase bill whose units have been sold cannot be changed.
What if I sell from the Android app without entering an IMEI?
The sale is accepted so the counter never stops, and it appears in the "Sales without IMEI" report so you can fix it later.
Does the customer see the repair status without calling?
Yes. The job slip has a QR code and a link to a status page for that job only. You can also send the update on WhatsApp with one tap.
Can I bill a repair and an accessory together?
Yes. When you deliver the job you bill it like any other sale, add accessories to the same bill, and the advance taken at booking is deducted.
Is it free for a single shop?
Not free, but every new business gets a 7-day free trial with everything unlocked, and no card is needed. After that, IMEI tracking, warranty and repair job cards are part of the Pro plan (₹499/month, ₹4,999/year or ₹9,999 for 3 years). Starter (₹299/month, ₹2,999/year or ₹6,999 for 3 years) covers billing and stock for accessories, GST reports, purchases and the books.
