Instead of determining the price of an item by quantity x unit price, you can use the second calculation factor to determine the total price of a document item by multiplying the unit price and two independent factors.

The function is available in the document types potential, offer, order, invoices and correction invoice.

The calculation factor can be activated via Master data > Billing > Edit billing settings . The unit of the calculation factor can be defined as the default value in the settings.

Example: Billing a subscription
A subscription with a price of €10 is to be billed for 12 months. The product is stored in the invoice with the quantity 2 (two subscriptions) and the calculation factor 12 (for 12 months). The calculation unit is months.

Example: Sale of wood in square metres
4 m² of wood is to be sold. The product wood is stored with a price of €4 per square metre. In the invoice, the length is stored as the quantity and the width as the calculation factor.

After activation, it is possible to enter the second factor in the line items of the document. When transferring documents (order → invoice), the calculation factor is adopted for the subsequent processes.

Placeholders are available for the calculation factor and the associated unit for output in the document layout, which you can find in the placeholder overview.
