The billwerk accounting export offers the possibility to automatically create deferred income and dissolve it over time.
The setting "Include deferrals" under "Settings > Accounts" controls this process:
How are deferred income items created in billwerk?
The deferrals are formed based on the net amount of a receivable, since the value-added tax for the entire receivable is due immediately.
The net amount of each invoice line is distributed evenly over the delivery period.
The portion that falls in the month of invoicing and in the past is not deferred.
The deferrals are always aggregated for the entire invoice, even if the posting are generated per lineitem.
Different delivery periods of different invoice lines are correctly processed when resolving the deferrals.
The deferrals are dated to the respective date of the bill.
How are the deferred income items on the liabilities side reversed in billwerk?
When the deferrals are created, postings that dissolve the deferrals are also created in the posting journal. These are then inserted into the financial accounting export with every new month and are dated to the last day of the respective month.
The deferral resolution per month is calculated based on the share of the month on the total deferral period.
What happens if an invoice for which deferrals were created is reversed?
If unresolved deferrals still exists at the time of the reversal, it is corrected accordingly. This also applies to the deferral resolutions.
