A "kiszámlázás" angolul "invoicing", esetleg "billing". Az "időszak" "period", a "könyvelési időszak" "accounting period", a "számlázási időszak" pedig "billing period". A "több időszakra szóló kiszámlázás" szerintem - invoicing for multiple periods" vagy - szövegkörnyezettől függően - "invoices that span more than one period".

"Use invoicing rules to determine when to recognize your receivable for invoices that span more than one accounting period. You can only assign one invoicing rule to an invoice.
Oracle Receivables provides the following invoicing rules:
•Bill In Advance: Use this rule to recognize your receivable immediately.
•Bill In Arrears: Use this rule if you want to record the receivable at the end of the revenue recognition schedule.
Oracle Receivables will treat all Invoices as being invoiced In Advance and with immediate revenue recognition, unless specified on the Invoice.
An example of where a Rules designation would be required would be an Invoice with Service Lines, where revenue would be recognized over a certain period, but not all at once."
