# Sell on due and take part payment

> Attach a customer while selling and leave the whole bill, or what is left of it, as due in their খাতা. Taking part now and the rest later works the same way.

If a customer will not pay the whole bill now, attach them to the cart while selling, type what they paid, and choose **Mark remainder as due**. The rest goes straight into their খাতা as **Sale on due**. If they pay nothing now, the whole bill is left on due.

## Before you begin

- A due can only be left with a customer attached. If they are not in Tukri yet, you can add them while selling (below).
- If you have not sold on Tukri before, start with [Make a sale at the till](https://tukri.bd/help/make-a-sale).

## Sell on due

1. Put the products in the cart on the till.
2. Attach the customer:

**On a computer:**
Click **Walk-in customer · tap to attach** at the top of **Current sale** on the right.

**On a phone or tablet:**
Tap the **Checkout** bar at the bottom to open the cart, then tap **Attach customer**.

3. In **Select customer**, type a name or phone number and choose the customer. Anything they already owe is shown beside them. For a new customer, tap **New customer** and enter a name and phone.
   ![Select customer: searching by phone number, with the customer's existing due beside them](https://tukri.bd/help-center/en/sell-on-due/pick-customer-phone.webp)
4. The cart now shows the customer's name and current due. Tap **Take payment**.

5. Type what the customer paid now, or leave it empty if they paid nothing. **Remaining** shows how much is left.
6. Tap **Mark remainder as due**. The remainder turns amber and reads **Due**.
   ![Payment: a total of 265 taka, 100 in cash, 165 due, and Mark remainder as due chosen](https://tukri.bd/help-center/en/sell-on-due/payment-due-phone.webp)
7. Tap **Complete sale**. The receipt shows what was paid and what is left on due, and for whom.

## What happens next

- The due part is added to the customer's খাতা as **Sale on due**: [The Due Book](https://tukri.bd/help/due-book).
- What they paid goes into the account you chose, and the goods sold leave your stock.
- When the customer pays later, record it in the খাতা: [Collect a customer's due](https://tukri.bd/help/collect-due).

## If something goes wrong

**It will not let me leave a due.** No customer is attached. A walk-in customer cannot owe; attach a customer first.

**A due limit warning appears.** The customer's total due would go past their **Due limit**. It is only a warning: you can still complete the sale.

**The customer paid later, but the sale still shows as due.** Recording the payment in the খাতা lowers the customer's due, but the sale in the **Sales** list keeps its original due. The customer's real balance is in their খাতা.
