Sales counter

Sell a phone by its code, and take an old one in trade

Every phone has its own code, so the counter sells that exact phone. An old phone can also be part of the payment for a new one.

8 things it does

Scan a phone's IMEI and it goes straight onto the sale

Professional only

Can I sell a phone by scanning its IMEI or serial number? Scan a device's code in the main entry box and that device is added to the cart at its own price. There is no product search and no capture window.

Without it

A customer wants a phone. You search for the model, open it, then find which of the phones in stock is the one in the case. The queue waits while you hunt.

With it

Scan the phone's code in the main box, and that exact phone goes into the cart at its own price. There is no search and no extra window to fill in.

Put the phone's code in the main entry box and press Enter. Either its IMEI or its serial number finds the phone, including a phone with two SIM slots, so you do not scan twice. If the phone is not in stock here, or was already sold, the till says so.

Other ways people ask this
  • sell a phone by scanning its IMEI
  • IMEI tracking software for a mobile shop
  • mobile shop POS software

See each phone's condition and warranty on the sale line before you sell it

Professional only

What does the cart show about a device I am selling? The cart line shows the device's code, condition, approval status and the end date of each cover. A device with its locks not cleared gets a quiet note that informs the buyer and never stops the sale.

Without it

A customer asks what they are buying. You look for the paper, or answer from memory, and the answer may not match the phone in your hand.

With it

The line shows the phone's code, its condition, its approval status and the end date of each cover. The customer display shows the same facts, never the cost.

The customer display shows the same facts, but not your cost.

Other ways people ask this
  • phone warranty tracking at the till
  • see a used phone's condition before you sell it
  • warranty dates on a phone sale line

Stop a discount from taking a used phone below its lowest price

Professional only

Is there a lowest price I can discount a device to? Yes. A device's own minimum price is the floor for a discount at the counter, and the product's minimum price applies when the device has none.

Without it

A customer asks for a better price on a phone. You want to close the sale, so you keep going lower, and the phone may sell for less than you meant to take.

With it

A phone can have its own lowest price. A discount at the counter stops at that price, so you can offer a fair deal without giving the phone away.

A device can have its own lowest price, and that price is the floor for a discount at the counter. The floor works on discounts only. A price you type in by hand is not checked against it, so look at the price before you confirm the sale.

Other ways people ask this
  • set a lowest price for each used phone
  • stop a discount going below a phone's minimum
  • limit discounts on second-hand phones

Take back a phone only when it is the one you sold

Professional only

How do I return a phone that a customer bought from me? On the return, a line sold with a device asks for one of the codes it was sold under, and then shows what the device was when it was sold. A different device is refused, with both numbers named, and the counter cannot override it.

Without it

A customer brings back a phone. You are not sure it is the one they bought, and a swapped phone throws your stock out. Checking by memory in a busy shop is easy to get wrong.

With it

On the return, the phone's code must match one of the codes it was sold under. A different phone is refused, with both codes shown, and the counter cannot override it.

Type it or scan it. The screen then shows what the phone was when it was sold, such as its condition, its battery and its warranty covers. A phone sold without a receipt is not taken back this way; buy it back on the purchase screen instead.

Other ways people ask this
  • return a phone by scanning its IMEI
  • check a returned phone is the one sold
  • serial number tracking for a shop

A returned phone goes back on the shelf at the cost you paid for it

Professional only

Where does a returned device go, and at what cost? A returned device that is sellable goes back into stock at the cost it left at. A defective one goes to To check at that same cost, and its refund needs a manager.

Without it

A phone comes back, and you put it back at the price on the shelf instead of the cost you paid. Later the phone's profit looks wrong, and you cannot say why.

With it

The phone goes back in stock at the cost it left at. A phone that is not fit to sell goes to To check at that same cost, so the figures agree.

A returned phone that you can sell goes back into stock at the cost it left the shop at. The phone comes back as the same unit, so its own history stays with it. A phone keeps its own cost, and is not averaged with other phones of the same model.

Other ways people ask this
  • used phone cost after a customer returns it
  • returned phone back in stock at cost
  • return a phone and keep its cost right

Let a customer pay part of a sale with their old phone

Professional only

Can a customer pay for a sale by trading in an old phone, tablet or laptop? Yes. The cashier chooses Trade-in on the payment step, scans the old device and fills in one form. The sale keeps its full price, and the shop buys the device into stock at the agreed value.

Without it

A customer wants the new phone but has an old one in a bag. Without a way to use the old phone, the sale may walk out of the shop.

With it

On the payment step you choose Trade-in, scan the old phone and fill in one form. The sale keeps its full price, and the old phone goes into your stock at the agreed value.

One form opens: its exact model, each code it has, its condition and checks, the seller and the value you agreed. The old device is bought from its seller and goes into your stock with no price of its own, until you set one. Only phones, tablets and laptops can be taken in trade.

Other ways people ask this
  • phone trade-in at the POS
  • take a customer's old phone as payment
  • old phone exchange billing

When the old phone is worth more, the customer is paid the difference

Professional only

What happens when the old device is worth more than the sale? The surplus is paid out in cash, or by bank or wallet as the cashier chooses. It is never given as store credit.

Without it

Sometimes the old phone is worth more than the sale. The customer wants the difference in their hand, not as a voucher to spend another day.

With it

The difference is paid out in cash, or from your bank or wallet, whichever you choose. It is never given as store credit.

If the old device is worth more than the sale, the till shows the amount to pay the customer. You choose how it is paid: cash, bank or wallet. Each device's payout is kept with its own trade-in, so the figures match what you handed over.

Other ways people ask this
  • trade-in value paid out in cash
  • old phone exchange software
  • pay back the difference on an old phone

Know who sold you each old phone, with their details on file

Professional only

What details do I need from the person selling the old device? The seller's national ID number is filled in from their customer record and shown in full on the form. Receipts and printed invoices show each trade-in with one code and any payout, never the national ID number.

Without it

A seller brings in an old phone, and you write their details on a scrap of paper. Later you cannot find who gave you the phone, or whether the details are right.

With it

The seller's details come from their customer record, so you do not type them twice. Each trade-in prints on the receipt with one code and any payout.

The seller's national ID number is filled in from their customer record, and the whole number is shown on the form, so you can check it against their card. The box is named after your country's own identity document. They never print the national ID number.

Other ways people ask this
  • record the seller of a used phone at the till
  • old phone exchange billing with seller details
  • phone trade-in receipt at the POS
