Per-piece-based product can be used for software licences, payslips or entries. For example, the number of entries changes from month to month, and it depends on the per-piece price.
First, a task field with 'Number' type should be created.
Select a task field from which the amount will be taken, and if needed, define ranges.
PS! If you want to bill based on the task field, review the settings for when the service will be billed. For example, you would like it to be billed at the end of the service when the task is finished.
Sum all matching rows - if this setting is on, the prices of all applicable ranges will be summed. If it is not turned on, the range in which the value falls is applied when pricing.
It is also possible to create more pricing periods, so that when the date arrives, the new prices are automatically used in the calculation.
The number from the task field will be considered for the invoice row calculation.
