EMI + device control for smartphone shops

Sell on EMI.
Stay in control.

LetzPay Locker records every deal your shop writes, tracks the instalments, and applies the lock the moment payment stops — while the customer's emergency calling stays open. One retailer app, one device app, one dashboard.

The retailer app

Everything the shop floor needs

Sixteen tiles on one home screen: record the customer, hand out keys, lock in bulk, keep the cashbook, and print a report without leaving the phone.

📷

Customer record with photo

Name, mobile number, a KYC photo, price, down payment, rate, tenure and start date — submitted in one screen. An enrol code comes back the moment it is created.

💰

Instalment plan, calculated

Enter the deal terms and the schedule is generated for you. The dashboard shows what is due, what is paid and what is overdue, per customer.

🔑

Keys & licence history

Available keys, consumed rows and full licence history with date-range downloads, so a dealer always knows what is left to hand out.

🔔

Bulk lock & unlock

Two dedicated tiles for the end-of-month sweep: select the shop's handsets and change their state together instead of tapping through them one by one.

📋

Cashbook

Total given, a four-figure daily summary and a portfolio row per customer — the ledger your collection routine actually runs on.

📄

A4 PDF reports

Two report buttons write a proper A4 PDF on the phone and hand it straight to Android's share sheet — for your own records or for the customer.

📱

App lock on every reopen

Optionally require your fingerprint or device credential each time the retailer app is reopened, so a handset left on the counter stays yours.

↻

Self-update

The app checks the version your deployment publishes and offers an in-place update — no re-scanning a QR every time something ships.

💬

Support inside the app

Contact Support, Dealer Feedback and Training Video tiles sit on the home screen and open straight to call, email or your own training link.

Who it is for

Built for people who finance handsets

Whether you sell five phones a week or run a channel of dealers, the flow is the same: record the deal, collect, lock when the money stops.

🏪

Mobile phone retailers

Sell on EMI from your own counter. Enrol the handset in under a minute and keep the lock/unlock button next to the customer's name.

💼

Dealers & distributors

Hand out enrol keys to the shops under you and watch which are consumed, pending or removed from your own screen.

🏢

Financiers running their own book

One dashboard for the whole portfolio: due dates, collection history, per-customer log, and a kill switch that needs exactly one click.

The control panel

What you can actually do to a financed handset

Every action below is a real, shipped capability — including the limits we deliberately built in.

⚡

One-click kill switch

From the dashboard, lock a device with a single confirmation. The action is recorded on that customer's timeline with who did it and when.

⏰

Automatic lock after grace

Miss the date and the grace period runs first (three days by default, configurable per deployment) before the lock applies.

📶

Works without internet

The lock time is held on the device itself with an offline clock, protected against clock-rewind and factory-reset tricks — so a phone with no data still locks on schedule.

📞

Emergency calling stays open

The emergency dial path is treated as untouchable. A locked handset can still reach emergency services — that is by design, not a gap.

🚨

SIM-change & security alerts

When a monitored handset swaps its SIM or trips a security condition, the alert goes to your shop over the configured SMS and WhatsApp channels — each alert sent once.

🔄

Unlock with a reprieve window

Release a handset and a twelve-hour reprieve window starts, giving the customer time to clear the due amount while the timeline keeps the record.

Limits we put in on purpose

  • ✓No Google-lock bypass. Factory-reset protection is armed, never circumvented. We do not remove or defeat Google’s protection on any device.
  • ✓Emergency dialling preserved. Emergency numbers stay reachable on a locked device.
  • ✓Every action is logged. Locks, unlocks and reminders land on the customer's own timeline.
  • ✓Your data stays yours. See the privacy policy
Three steps

How it works

From a blank phone to a protected sale, in the time it takes to fill the invoice.

Enrol the handset

Open Setup QR in the retailer app and scan it on the customer’s phone: the device app is installed from your own server and the running QR provisions it against your shop.

Record the deal

Photo, price, down payment, interest rate, tenure and start date. The instalment schedule is generated and an enrol code is issued for that customer.

Collect, or lock

Reminders go out, the dashboard tracks due dates. Pay and the handset is released with a reprieve window; don’t, and the lock applies after the grace period.

Safety first

What we will and will not do

A device-locking tool is only usable if its limits are written down. Here are ours.

🛡️

Consent at enrolment

The setup flow shows the customer what the shop is installing and links the privacy policy and terms before the device is linked to your account.

🔒

The retailer app protects itself

Optional app lock asks for your fingerprint or device credential every time the app is reopened, and sessions are bearer tokens rather than stored passwords.

💾

Your own deployment

The dashboard and API run on your server with your own database, your own admin password and your own domain — not a shared multi-tenant account.

Frequently asked questions

Is it legal to lock a customer’s phone?

You finance the handset and the customer agrees to the setup flow — including the published terms — before the device is linked. We supply the tooling: emergency calling is preserved, factory-reset protection is never bypassed, and every action is logged against the customer. Your own counsel should confirm the contract you sign with each buyer.

What happens if the customer’s phone has no internet?

The lock time is stored on the device with an offline clock, protected against clock-rewind and reset attempts, so the schedule still fires while the phone is offline. When it reconnects, the dashboard catches up with the device state.

Can the customer just uninstall it?

No. The device app is installed as the device owner, so normal Android uninstall does not apply — removing it is an action your shop takes from your own dashboard.

What happens when an instalment is missed?

Reminders go out first over the configured SMS and WhatsApp channels, then the grace period runs (three days by default). After that the lock applies — automatically or from the kill switch — and unlocking opens a twelve-hour reprieve window.

Which phones does it work on?

Android 8.0 (API 26) and above, from any brand that supports device-owner management. iPhones are not supported: device-owner enrolment is an Android capability.

How do I get started?

Call or email us and your shop account is set up with its own admin credentials and enrolment keys. Then install the device app with the Setup QR and add your first customer from the retailer app.

How much does LetzPay Locker cost?

Pricing depends on how many shops and handsets you run. Contact emi.letzshop1@gmail.com or +917002066184 for a quote.

Is my shop’s data secure?

Each deployment keeps its own database on its own server, behind HTTPS, with token-based sessions and an optional app lock on the retailer app. What we collect and why is set out in the privacy policy.

Who do I contact when something breaks?

Email emi.letzshop1@gmail.com or call +917002066184. The same contact is on the retailer app’s Contact Support tile, so help is one tap away from inside the app.

Get started

Ready to stop chasing payments?

Download the retailer app, sign in to your dashboard, or talk to a human first — whichever you prefer.

Both downloads come straight from your deployment, so the version you get is the version your server publishes.

EMI default protection for smartphone retailers

LetzPay Locker ties each financed handset to an instalment schedule. When a payment runs past its grace period the lock applies automatically or from one click in the dashboard, so a missed EMI stops being a phone call and starts being a solved problem.

Customer records, keys and a cashbook in one app

Every customer carries their photo, deal terms and enrol code; every key is accounted for in Available Keys, Key History and Licence History; and the Cashbook keeps total given and daily collections where the shop can see them.

Made for the way Indian shops actually work

Amounts in rupees, reminders over SMS and WhatsApp for customers who are not on email, an offline lock clock for patchy connectivity, PDF reports on the phone itself, and a phone number you can call for help.
