# What do I do if a POS customer wants to buy more stock than is available?

KB578.htm

## Overview

Normally when selling items to a point of sale customer, you will raise a POS invoice for the transaction.

However, if the customer wants to purchase more items than you have available, this is technically no longer a point of sale transaction and is more appropriate entered as a Sales order.

## Process

If there is not enough in stock for a point of sale transaction, that means the customer arrived at the counter with some stock and presumably asked for more.

For example, a customer wants to buy 15 items of which you only have 10 in stock, and they want to pay for them all and will collect the remaining 5 at a later date.

Because you are now performing a pre-sale, this is fundamentally no longer a POS sale.

You should record this sale using the Sales order function with a partial dispatch of the items you have available.
