What businesses abroad send to Brazil

Mail that has to reach people in Brazil on paper, sent in batches or one by one as your system needs it.

  • Invoices and boletos

    Monthly invoices with the boleto payment slip for customers who pay on paper.

  • Collection notices

    Payment reminders and formal notices for overdue accounts.

  • Customer notices

    Contract changes, policy updates and notices your customers must receive in writing.

  • Reminders and relationship mail

    Appointment, service and renewal reminders, plus birthday and welcome letters, printed in your colors.

  • School communications

    Tuition boletos, academic notices and documents for students and parents.

  • Condominium notices

    Boletos, meeting calls and notices for every unit managed by a property manager.

Two ways to send in bulk

For example, a property manager sends the annual meeting call to every unit it manages, and a lender sends reminders as accounts fall behind.

Dashboard

Upload the PDFs and the addresses for the batch. Before you confirm, you review the recipients and the total. This suits periodic mailings such as a meeting call or a yearly statement.

API

Your system creates one mailing per document, at the moment it produces the document. This suits recurring mail such as invoices and reminders.

Your PDF, printed the way you designed it

Logos, colors and layout come out as they are in the file. You choose color or black and white, and each mailing arrives in a well-finished envelope.

A clinic, a car service shop or an insurer, for example, can send a color reminder with its own logo when an appointment, a service or a renewal is due.

Invoices for customers who pay on paper

Many customers in Brazil still pay with the boleto that arrives with their invoice. Your billing system creates the PDF, and CartaFlow prints and posts it to each customer every month.
