Dates of performed services visible when editing the document

In the case of issuing invoices for services, the realization of which is long-term, e.g. subscription, you can, while generating such a document, set dates on which the services should be provided.
Often those are the dates of conclusion and termination of the agreement in force between the Seller and the Buyer.
To activate this function, go to Settings> Account settings> Configuration> Invoices and documents> Use date of payment on invoices.



After saving the changes in settings and attempting to create a document, two windows will appear in the See more options section, named: Paid from, Paid till. Choose there the appropriate dates.


                                                                                                                                                                                                                                          

Note.
