1. A/R invoices must be generated from the A/R system and sent with necessary supporting documents to all debtors as per the pre-defined time schedule (ie within 2 days of checkout or monthly for some travel agents).
2. The date of mailing out the A/R invoice must be recorded. Alternatively, emailing invoices in a PDF format should be considered.
3. A copy of the A/R invoices must always be kept in debtors’ filing until full payment has been received.
