# Warranty check by serial number

> Give a product a warranty period, type the serial or IMEI when you sell it, and later look up by serial, invoice, name or phone whether it is still covered.

If you sell items with a warranty, such as phones or electronics, use **Warranty check**. Give the product a warranty period, type each unit's serial or IMEI when you sell it, and when the customer comes back, look it up by serial, invoice number, name or phone to see whether it is still covered. The invoice prints the serial and the date the cover ends.

## Before you begin

- Warranty check is an optional feature and starts switched off. To turn it on, open **Settings** › **Features**, switch on **Warranty check** and press **Save**. The owner and Admins can do this. More in [Turn optional features on or off](https://tukri.bd/help/turn-features-on-or-off).
- Once on, **Warranty check** appears in the menu: under **Sell & Stock** on a computer, in **Menu** on a phone.
- Looking up a warranty needs "See sales history". All three roles (**Owner**, **Admin**, **Staff**) start with it, so staff at the counter can check without the owner.

## Give a product a warranty

1. Open the product from **Products** to edit it, and go to the **Selling** step at the top.
2. Turn on **Sold with a warranty**. It only shows while the feature is on.
3. Enter the **Warranty (months)** and choose who it is **Honoured by**: **This shop** or the **Manufacturer**.
4. If you like, fill in **What the warranty covers**; it prints under the warranty line on the invoice.
5. Tap **Save**.

## Record the serial when you sell

1. Add the product to the cart. On a phone, tap **Checkout** at the bottom to open the cart. The product's line has a serial box ("Type or scan the unit's serial") with the warranty months under it.
2. Tap into the box and type the serial, or keep the cursor in it and scan the unit's barcode with a scanner.

3. Take payment and complete the sale as usual. See [Make a sale at the till](https://tukri.bd/help/make-a-sale).

The serial is optional. Each cart line has one serial box, and adding the same product again only raises that line's quantity. So for two units of one product on one bill, type both serials in that box separated by a space (a lookup by either one finds the line), or sell each unit as its own sale. The cover ends the given number of months after the sale date.

## Check a warranty

1. Open **Warranty check** from the menu.
2. Type a serial, an invoice number, the customer's name or phone into "Serial, invoice no, name or phone".
3. Each matching item shows **Under warranty** or **Expired**, with the date and the sale it came from.

## Good to know

- The warranty is fixed at the moment of sale. Changing a product's warranty later does not change items already sold.
- Turning the feature off hides **Warranty check** and the warranty part of the product form; nothing is deleted. Products that already have a warranty period keep it, so their serial box still shows at the till and their warranty still prints. To stop that, turn off **Sold with a warranty** on those products while the feature is still on.

## If something goes wrong

**Warranty check is not in the menu.** The feature is off, or your role does not have "See sales history".

**"Nothing found"** Try the invoice number instead. Only items sold with a warranty period appear, and voided sales are left out.

**An item sold earlier shows no warranty.** The product had no warranty when it was sold; the warranty is taken from the product at the time of sale.

**There is no serial box in the cart.** The product has no warranty period.

**Scanning into the serial box adds a product instead.** Tap into the serial box first, then scan.
