Mobile resellers need a different kind of point-of-sale system from a shop that sells only fast-moving packaged goods. A handset can have a high value, a unique IMEI or serial number, a warranty record and an accessory sale attached to it. One incorrect stock movement can therefore create a customer-service problem long after the counter sale is finished.
This guide explains how to assess a mobile reseller POS in Sri Lanka. It is useful for shops selling phones, tablets, accessories and related services, whether they operate one counter or move stock between several locations.
Start with the sales journey, not the product list
Map a normal sale before comparing software. A customer chooses a handset, asks about the warranty, adds a case and screen protector, pays by one or more methods and expects a clear invoice. The team should be able to find the sale later without relying on a handwritten note or a staff member’s memory.
Ask a supplier to demonstrate the real journey with a serialised device, not a generic sample item. The demonstration should include receiving the phone, entering or scanning the serial, selecting it during a sale, producing a bill and locating that sale later. If your store also handles repairs, make that a separate demonstration: selling, warranty work and repair intake are connected but are not the same workflow.
Serial and IMEI control is a core requirement
For serial-tracked products, Distribook can record serial numbers during goods receiving and keep them connected to the product and stock location. The system validates that the serial count matches the received quantity and prevents duplicate serial entries. That is more useful than a spreadsheet when several people receive and sell devices.
Your operating rule still matters. Decide who may correct a serial, who may reverse a return, and what must be checked before a device leaves the counter. A good system supports the process; it does not replace it.
Receive devices with enough context
Receiving is where future stock accuracy starts. A proper goods-received workflow should let the team record the supplier, quantity, unit cost, selling price, serials and any relevant batch information. Check whether a posted receipt creates an auditable stock movement instead of silently changing a quantity.
For a reseller with a central store and branches, also ask how transfers work. A transfer should identify the sending and receiving location, preserve the device identity where serial tracking is enabled and leave a history that staff can investigate later.
Make warranties and repairs explicit
Customers expect a mobile shop to find warranty details quickly. Distribook includes warranty and repair workflows for configurations where that module is enabled. The useful test is practical: can a staff member search the device identifier, see the related sale and handle the claim with the right permission?
Do not promise a warranty period that the product, distributor or policy does not support. Record the commercial terms clearly on the invoice and train staff to distinguish a manufacturer warranty, shop warranty and paid repair.
Protect counter and stock decisions
Handsets make permission design important. Separate the ability to sell from the ability to change a price, cancel a bill, edit a serial or adjust stock. Review reports for stock movement, sold serials, returns and open repair work. These controls are as important in a single shop as they are in a multi-branch reseller.
Questions to ask in a demo
- Can we receive and sell serialised devices without retyping the same identifier?
- What happens when a serial is duplicated, returned or moved to another branch?
- Can a supervisor see a history of the sale, warranty and later repair activity?
- Which permissions control price changes, cancellations and stock adjustment?
- How are accessories, non-stock services and mixed payment handled?
For a broader workflow overview, read the mobile shop POS guide and the phone repair workload guide. A demonstration should use your own product types and real edge cases before you commit to a rollout.
Frequently asked questions
Does every mobile item need a serial number?
No. Chargers, cables and cases may be quantity-tracked rather than serial-tracked. High-value devices are the obvious place to use serial control.
Can a mobile shop use the same POS for sales and repairs?
It can when the enabled configuration includes the necessary warranty or repair workflow. Confirm the exact scope, staff roles and handoff process during the demo.
What is the first implementation step?
Clean the product list, decide the serial rule and test receiving, sale, return and warranty lookup using a small set of real devices.
