Everything PhoneSell Pro does — on one page

Customer, phone brand and model, IMEI, installment plan, and a final review — five short steps put a phone on the Locker, and the installment contract is created along with it.

If the phone was already sold on installment from the shop’s POS, just pick that sale from the list and the customer and installment plan fill in on their own.

Keep the Enroll app on your own phone, connect the customer’s phone with an OTG cable or Wireless Debugging, and tap Enroll. The PhoneSell app is installed as Device Owner without a computer.

For phones where the Enroll app doesn’t work, plug the phone into a laptop with a USB cable and run the tool — one click installs the PhoneSell app and makes it Device Owner.

After enrolling, a QR appears in the panel. Open the PhoneSell app on the customer’s phone and scan the QR to log in — no number or password to type.

Each new phone you add to the Locker uses one device credit. How many credits are left, when and how many came in, and which phone used each one — it’s all written in the ledger.

Tap “Restrict” on the phone’s page or in the device list and the phone locks; tap “Restore” and it opens. If the phone is online, it happens in a few seconds.

You write what the locked phone’s screen says — for example “Installment overdue, please contact the shop”. It also shows the amount due and the shop’s contact details.

Once an installment date passes and the grace days you set are also over, the phone locks on its own. Every contract is checked automatically each day — you don’t have to tap anything.

When a payment is overdue: first a reminder notice, then a warning wallpaper and the camera turned off, and finally a full lock. Once paid, the phone goes back to normal step by step.

When you record an installment in the panel, or the customer pays online, the phone opens by itself as soon as the overdue amount is cleared — no need to tap unlock separately.

With the “Need more time” button on the lock screen, the customer can open the phone for a few days on their own. How many days and how many times — the shop sets those rules entirely.

Even without internet on the phone, as long as the SIM is active you can send a lock or unlock by SMS — to one phone, or filtered to many phones at once.

No internet, and SMS isn’t getting through either? The phone’s page has two 8-digit codes. Tell the customer the code over a call — they type it on the lock screen and the phone opens.

Which staff member gave out which phone’s code and when, which phone used a code, and when codes were changed — all in one list, with the customer’s name.

The phone keeps your lock rules stored on itself. So even with data off, a SIM removal or a reset attempt still locks it, and it picks up any new rules as soon as it’s back online.

Turn on the rule if you want — if the phone has no internet for longer than the hours you set, it locks itself, and opens again once it connects over the internet.

On an enrolled phone the PhoneSell app sits as Device Owner. The customer can’t uninstall or stop the app, or reset the phone from Settings, to break the lock.

If the customer takes out the SIM or puts in a different one, the phone locks right away — even without internet. Simply turning a SIM off and on in Settings does not lock it.

Many phones hide the SIM’s own number. The customer types the phone’s SIM number, a code is sent to that number, and the phone reads the code and matches it on its own — so you learn the real number.

The customer can use normal settings — Wi-Fi, brightness, ringtone — all of them. It only bounces them away from the pages that could break the lock (reset, app info and so on).

Rooting the phone, unlocking the bootloader, turning on developer mode or USB debugging, switching off the Locker’s permissions — when attempts like these are detected, they arrive in the panel as security alerts.

If a phone sends no news for a long time, that silence itself is treated as suspicious — the phone moves onto the security list, so you don’t mistakenly assume “all is well”.

While installments are running, the customer can’t log out of the app or turn off protection — that needs the shop’s secret PIN. Once you release the phone after the last installment, it’s no longer needed.

See each installment phone’s last position on a map, and tap “Locate” to make the phone send a fresh location right then. The history of past locations is kept too.

Set an area for a phone. If the phone goes outside that area it will lock — whether that’s switched on is up to you, in Lock Rules.

A page made to leave open on the shop’s TV or a big monitor — how many phones are online, today’s collections, which phones have alerts, and a map of all phones, updating by itself.

The first page you see in the Locker shows total customers, installment phones, how many are locked, total overdue, credits left and phone status — with a map of all phones below.

SIM changes, reset attempts, attempts to stop the app — every alert collects on the Security page. If you like, they also reach the shop’s own Telegram instantly.

If a customer’s phone is stolen or lost, mark it “Lost” from the phone’s page — the phone moves into a separate status, and its location and records stay in your hands.

Each phone has its own page with the customer, IMEI, battery, last online time, location, installment contract and command history — plus every control button.

Send a plain notice to the customer’s phone, or a pop-up that won’t go away until a button is tapped, or an alarm with sound — remind them without locking.

Remotely set an installment warning as the phone’s wallpaper, and put the old one back later. If needed, turn off the camera to add pressure, and turn it back on once they pay.

From the list of apps on the phone, tap any app to lock it — games or social media, for example. You can apply pressure without shutting down the whole phone.

Restart the phone remotely, and when needed set or clear a PIN on the phone’s screen lock — without bringing the customer to the shop.

The shop’s general Lock Rules apply to everyone, but if you want a different rule on one particular phone, change it from that phone’s page — the others aren’t affected.

Enter the price, down payment, profit %, number of installments and type, and every installment’s date and amount is created — with the option to round to whole numbers.

Keep the customer’s NID, address, photo, and photos of both sides of the NID card. Add the guarantor’s name, phone and NID to the contract — they appear on the printed agreement too.

Print each contract’s agreement with one tap, ready for the customer to sign. Set up the shop name and terms your way once.

If a customer falls on hard times, rearrange the dates and split of the remaining installments. Both the old and the new schedule are kept on record.

All contracts in one list — how many installments are paid (e.g. 3/6), how much is left, how many days late. Print a statement for each contract and for each customer’s transactions.

When the customer pays, record the payment from the contract or customer page and pick which account (cash/bKash/bank) it went into. The receipt prints or shares, and the amount due goes down.

All installment collections in one list — how much came in, who paid, when. Recorded one by mistake? Tap “Reverse” and the amount due goes back to what it was.

With online payments switched on, the customer can pay the installment with bKash straight from the locked phone. Once the money arrives the phone opens in a few seconds, and the money goes into your Wallet.

The customer sends money by bKash, Nagad, Rocket, Upay or bank and submits the transaction ID or a screenshot from the app. Once you check and approve it, the installment is credited and the phone opens.

When an installment falls due or goes overdue, the customer automatically gets an SMS with a link — tapping it shows their own balance and lets them pay online.

When you receive the last installment, tap “Release device” — the Locker’s control is removed from the phone cleanly and the phone belongs fully to the customer. If it was a mistake, the record can be reactivated.

Installment collections, overdue installments, defaulters, down payments, contract list, phone status, command log, security events — every Locker report, by date.

Every Locker task in the shopkeeper’s Android app — the phone list, adding new phones, lock and unlock, contracts, collections, Live Wall, Lock Rules, alerts and credits.

The customer’s app lives on the installment phone itself — amount due, next date, installment schedule and payment history. From there they can pay installments and message the shop.

Two ways to enroll a phone — the Enroll app on your own phone (OTG or Wireless Debugging), or the tool on a Windows/Mac laptop. Both can be downloaded from the apps page.

Without installing anything, log in from your phone’s browser and do all your shop and Locker work — the pages adapt to a small screen.

A website of the shop’s own, where customers browse products and place orders. Products and stock come straight from the shop software — nothing to upload separately.

Customers order with their name, phone and address — no login needed. Orders arrive in the panel — confirm one and stock goes down just like a sale; when it’s ready, the customer gets an SMS.

A private link for every customer — sent by SMS. Without logging in, the customer sees their own dues and can pay online from there.

Installment receipts, expense vouchers and invoices — each has an online link you can send by WhatsApp or SMS. Proof without paper.

New models, Eid offers, the shop being closed — write once and send to selected customers or staff. Write {name} and each person sees their own name.

Thanks for a purchase, payment received, installment paid, contract completed, phone locked or unlocked, every repair stage, orders, warranty, salary — as soon as it happens, an SMS goes out.

Send notifications straight to the phones of customers who have the app — with no SMS cost. You can also see how many received and opened them.

Customers message the shop from the customer app or the lock screen, and you reply in the panel’s inbox. New messages announce themselves with a sound.

Each branch keeps its own stock, cash and staff. Send goods from one branch to another with a record, and the owner sees every branch from one place.

Give every staff member their own login, and use roles to decide who sees or does what — sales only and not accounts, for example. A Locker-only shop sees only Locker permissions.

The panel, the shopkeeper app and the customer app run in Bangla, English, Urdu and Nepali. Each user picks their own language.

After logging in, choose whether today is Locker work or shop work. Even once inside, tap the button at the top to switch to the other section. Reorder the menu and star your favourite pages.

Who did what and when — important actions like locking, unlocking, giving out codes and deleting — are written in the audit log. See which devices your account is signed in on, and sign them out.

If a larger business has its own software, connect it to PhoneSell Pro with API keys, and use Webhooks to receive events like locks and payments straight into your own system.

For those who sell the software to shop after shop, a separate dealer panel — your shops, credits, bills and statements; under your own name, logo and domain.
