To add the same item (e.g. with different prices) as separate lines in a manual order, you need to change a setting in the corresponding order type.

Change setting for separate lines

If you currently add an item that already exists in the order, by default only the quantity of the existing line is increased. Here is how to change this behaviour:

1. Navigate in your system to Order » Order types » Order.
2. Look for the option Display of added items in the shopping cart.
3. Change the setting from Create as one order line, quantities are increased to Create as separate order lines.

Afterwards, you can add the same item multiple times as its own line to the order and adjust the prices individually.

Important note

Please note that this setting applies to all new orders that you create manually via this order type.
