I need your help for dunning interest, I need to put different interest indicator for the open invoices, if invoice is overdue after expiry of FLEXIBLE REAL ESTATE contract. For e.g.
FLEXIBLE REAL ESTATE contract validity 01/01/2006 to 31/12/2006
-if any rental invoice of contract is over due during above period i.e. 01/01/2006 to 31/12/2006 interest should be calculated at 18%.
- if any rental invoice of contract is over due after expiry of contract i.e. after 31/12/2006 interest should be calculated at 12%.
give your expert advice.
