The problem
Credit sales grow revenue — and quietly destroy margin.
Every dealer knows the cycle. The phone leaves the shop, the payments slow down, and recovery costs more than the handset is worth.
Chasing replaces selling
Staff spend their week on phone calls and door visits instead of moving stock. Follow-up is manual, undocumented and easy to skip.
No leverage after the sale
Once the handset walks out, the only pressure you have is goodwill. A customer who stops answering has already won.
Books that don't agree
Schedules in one notebook, payments in another, and no single answer to "how much is actually outstanding this month?"
How it works
Four steps from shop floor to secured loan.
No new hardware, no custom ROM. Any modern Android handset becomes a managed device before the customer leaves the counter.
-
01
Scan to enroll
Generate a QR from the dashboard and scan it on a factory-reset phone. The device provisions itself as a managed device and enrolls automatically.
-
02
Set the loan
Enter deposit, term and flat interest. Linda builds the instalment schedule, tracks every payment and flags overdue accounts on its own.
-
03
Remind, then enforce
SMS reminders go out before the due date. If an account stays overdue, the handset locks to a payment screen — calls to emergency numbers still work.
-
04
Paid means unlocked
A confirmed ClickPesa payment releases the device within seconds — no staff action, no call to the shop, no argument at the counter.
The platform
Everything the loan book needs, in one place.
A staff dashboard, a device agent and a collector app — designed together, so what you see on screen is what is actually happening on the handset.
Instant delivery, offline tolerant
Push notifications trigger an immediate check-in. If the phone is off or out of coverage, the command is waiting the moment it reconnects.
Mobile money that closes the loop
ClickPesa collections post straight to the instalment schedule. Verified webhooks mean a payment updates the loan and the device without anyone re-typing it.
Automatic SMS reminders
Beem-powered reminders and warnings fire on schedule in the language your customers read. Most accounts settle before enforcement is ever needed.
Multi-shop by design
Run several branches or franchises from one account. Each shop's customers, devices and money stay strictly separated — enforced at the database, not just the screen.
Reports you can act on
Outstanding balance, collection rate, ageing buckets and staff performance — daily, monthly and annual, filtered by branch or agent.

Let our call centre do it.
Subscribe to Managed Collections and trained platform collectors work your overdue cases for you. You keep the customer relationship, the loan and the lock controls — we supply the follow-up capacity.
-
Every contact is proven. Calls and SMS are started from the system and verified against the device log — no free-typed "I called them".
-
Promise-to-pay tracking. Each commitment is logged with a date and followed up automatically when it slips.
-
Your cases stay yours. Collectors see only the cases assigned to them, and never another dealer's book.
-
Unlock stays with you. Collectors can note, promise and escalate — releasing a device remains your decision or an automatic result of payment.

Security & trust
You are holding customers' devices. We treat that seriously.
Locking a phone is a powerful action. Every part of the system is built so it can only happen for the right device, from the right shop, for the right reason.
Hardware-backed credentials
Each device's token is sealed in the Android Keystore. Nothing useful sits in plain storage on the handset.
Strict shop isolation
Every record carries its shop identity and is filtered at the database layer, so one dealer can never read another's book.
Roles that match your org
Owner, manager and agent permissions are enforced server-side — an agent cannot release a device just by finding the URL.
Signed payment webhooks
Payment callbacks are checksum-verified before they can mark an instalment paid or unlock a handset. Forged notifications are rejected.
Tamper-resistant agent
Provisioned as a device owner with a verified signing checksum, the agent cannot simply be uninstalled by the customer.
Complete audit trail
Who issued a lock, when it was delivered and when the device acknowledged it — recorded for every command, permanently.
A locked phone is not a dead phone. Emergency calling stays available, and the lock screen shows the customer exactly what is owed and how to pay it — so recovery is a payment, not a confrontation.

Questions dealers ask
Still unsure? Book a demo and we'll walk through your exact setup.
Can the customer remove the lock app?
No. The agent is installed as an Android device owner during provisioning, which blocks uninstalling it and stops a factory reset from returning the phone to an unmanaged state.
What if the phone is switched off or has no internet?
Commands sit in a queue on the server. The moment the handset reconnects it checks in and applies whatever is pending — a lock issued yesterday still lands today. Devices also check in periodically on their own, so nothing depends on the customer cooperating.
Does a locked phone still make emergency calls?
Yes. The lock screen restricts normal use but keeps emergency dialling available, and it clearly shows the outstanding amount plus how to pay — so the customer can resolve it themselves.
How fast does a device unlock after payment?
A verified ClickPesa confirmation triggers the unlock immediately and a push notification wakes the device to collect it — typically under a minute on a connected handset. No staff member has to be at the shop.
Can I run more than one shop on one account?
Yes. Linda is multi-tenant from the ground up. Each shop has its own customers, devices, loans and staff, and owners can see across their branches while agents only see their own.
Which handsets are supported?
Any modern Android phone that supports Android Enterprise provisioning — including the Tecno, Infinix, Samsung and Xiaomi models most commonly sold on credit. Enrollment happens from the factory-reset setup screen via QR code.
