Mark Invoice Paid

Hello Everyone

Could the experts throw some light on this issue and if there are any workarounds to handle this scenario.  Is there a way we can have invoices marked paid without going thru actual payment and clearing cycle , we have intercompany invoices which are invoiced but since its between sister company payment /cash clearing is not required . In 11i we have Pay in Full functionality ,in R12 is there a method we can have invoices marked as paid so that they don't cause issue during period close

Thanks
