Payment Demand Packets

Why this topic matters

Invoice disputes and overdue-payment follow-ups are stronger when the recipient gets a clear demand, the invoices, and supporting records in the same packet. PostalForm helps turn those materials into a reviewable packet before mailing.

When to use these workflows

  • A customer has ignored emailed invoices and you need a mailed payment demand.
  • You want to include invoices, contracts, delivery records, or correspondence as exhibits.
  • You need a repeatable process for documenting payment-recovery mail.

How it works

  1. Choose the workflow that matches the packet you need to send
  2. Answer the guided questions and upload attachments when needed
  3. Review the generated PDF before checkout
  4. PostalForm prints and mails the packet through USPS
