Service performance period on customer invoice

[d_weinberg]

Nowadays many ByDesign using companies are managing long term customer contracts that are invoiced by an invoice schedule. E.g. in the areas of licensees or rental services this is often the case. When invoicing is due they face the natural requirement of having the correspondent time period visible on the invoice document. But this is currently not possible within the ByDesign standard, because the generated invoice request does not know anything about the service performance period that is invoiced by the invoice schedule.

To address this issue we plan to develop an Add-On with which the user can specify the service performance period for an invoice schedule entry. The Add-On then maps customer invoice requests onto the corresponding invoice schedule entry by invoice date and amount. Having that connection established we are capable of writing the performance period to the customer information field, which can then be printed on the invoice form.
