Serial Numbers, Warranty & Returns

For phones, appliances and anything under warranty, *how many* isn't enough — you need to know which one. Track each unit by its IMEI or serial and you can answer, months later, whether a specific handset came from you, when, to whom and at what price.

Turn on serial tracking

Edit the item in Product Catalog and tick Each unit has an IMEI / serial. Set Warranty (months) at the same time if the item carries one. Turning serials on also turns on stock tracking — you can't identify units of something you aren't counting.

Record serials as they arrive

1. 1Go to Profile → Stock, Purchases & Expenses → Stock.
2. 2Find the item and tap the barcode icon.
3. 3Scan or type the serials — one per line, or separated by commas.
4. 4Save.

Sell a specific unit

On the invoice, a line for a serialised item shows an extra field for the IMEI / serial numbers being handed over. Enter them (comma separated, or scan straight in). When the invoice is issued, those exact units are marked sold and tied to that invoice and customer.

Look up a unit

This is the reason the whole feature exists. At the top of the Stock tab, type or scan a serial into Look up an IMEI / serial and you get that unit's whole life:

• Which item it is, and whether it's in stock, sold or returned.
• Warranty — covered until when, and how many days are left.
• Where it came from: the supplier bill and date.
• Where it went: the invoice number, date and the customer who bought it.

How warranty is counted

Warranty runs from the date you sold it, not from when it arrived in your shop. A handset that sat in the display case for four months hasn't used any of its cover. Months are calendar months, so twelve months from 15 March is 15 March the following year.

Handle a return

Look the unit up, then tap Record a return. You'll be asked why it came back, how much you refunded (leave it at zero for a straight swap), and whether it goes back on the shelf.
