3. Timely sending of electronic invoices
During the collection process, it is essential to provide the client with timely notices so that they are aware of each new payment cycle and thus avoid delays in the payment of their installments. In addition to timely sending of electronic invoices, there are a series of additional notices that must also be made, such as payment reminders before the due date (preventive collection), overdue invoices (which can be sent via direct mail, email or via SMS with a link or WhatsApp), payment reminders.

In each case, different means can be used to notify customers, whether by telephone with an agent call, or a robocall (also called a "call blaster"), by email or by means of an SMS text message, an MMS multimedia message, a WhatsApp message or an RCS message.
