Hello Vincent, into the Netherlands your explanation is not allowed.
Payments are mostly done via bank and have a bank transaction date that should match in ERP too. Data entry in ERP for Bank and Cash transactions can be booked in e.g. Januari with period 12 and a date in period 12 e.g. 30 December.
If you have Payment transaction done in Januari for e.g. the December work done of your external accountant, one can make a reservation in December for that amount without tax and when payment is done contrabook the reservation. That way the costs will be taken in december and your financial administration will keep clean. Taxes are in the right period, namely the Januari where you received the invoice.

So in my opinion period and date should ALWAYS match.
