Yes. I found a few vendors that are much closer to what you mean than generic “AR automation” platforms.
| Vendor | AR/collections automation | Physical letters | How close to your ask |
|---|---|---|---|
| InvoiceFactory | Yes — automated invoice collection, reminders, escalation | Yes — automated printing + mailing + tracking | ⭐⭐⭐⭐⭐ |
| Blixo | Yes — AR collections/dunning workflows | Yes — postal mail alongside email/SMS | ⭐⭐⭐⭐⭐ |
| Quadient AR (formerly YayPay) | Yes — sophisticated AR/collections automation | Letters/dunning automation, but physical fulfillment needs clarification | ⭐⭐⭐⭐ |
| PostGrid | Mail automation/API rather than a full AR platform | Yes — print, mail, tracking | ⭐⭐⭐⭐ as a mail layer |
| PastDue | Collections automation for collection agencies | Yes — automated validation/dunning letters, with print/mail handoff | ⭐⭐⭐⭐ |
| RevSpring / PCI Group / Renkim | Primarily communications infrastructure for ARM/collections | Yes — physical collection letters at scale | ⭐⭐⭐ as an AR software replacement |
InvoiceFactory is the cleanest match I found. It explicitly describes itself as AI-powered invoice collection software and says its workflow includes automated email, SMS, physical letters, and calls. Its physical-letter feature specifically says printing and mailing are automated and delivery is tracked.
Blixo is another particularly interesting match. Its AR/collections platform says automated reminders can be sent by email, text, and postal mail, alongside dunning, dispute handling, payments, and cash application.
Quadient is worth investigating if you're looking for something more established/enterprise-grade. Quadient's AR product (formerly YayPay) automates collections and can schedule dunning letters based on invoice/customer status. Quadient also has a separate communications platform capable of producing and delivering physical communications.
The important distinction is that “generates a letter/PDF” isn't necessarily the same as “automatically puts the letter in an envelope and sends it through USPS.” For example, NetSuite's native dunning functionality can generate printable dunning letters, but its documentation says physical letters go through a PDF printing queue rather than being automatically mailed.
There are also companies whose job is essentially “when your AR system tells us to send a collection letter, we print and mail it automatically.”
If your desired workflow is:
Invoice becomes overdue → software waits X days → sends email → if unpaid, automatically sends a physical demand letter → escalates again → stops automatically when paid
then I'd shortlist InvoiceFactory, Blixo, and Quadient AR, and separately evaluate PostGrid/Lob if you already have an AR system you like and only need the physical-mail component.
If you tell me what accounting/ERP system you're using (QuickBooks, NetSuite, Sage Intacct, Dynamics, custom, etc.) and whether these are B2B invoices or consumer debts, I can narrow this to the 5 vendors that actually fit your stack, including pricing and whether the letter is genuinely mailed automatically versus merely generated for printing.

While most standard accounts receivable (AR) automation and dunning software (such as Chaser, Gaviti, or Upflow) focus strictly on digital workflows like automated emails and SMS reminders, sending physical, printed collection letters via postal mail is usually handled via one of two approaches:
The primary options and methods that offer this capability include:
Instead of traditional AR software printing letters in-house, modern companies typically connect their accounting/billing stacks to direct mail automation APIs. When an invoice hits a specific aging threshold (e.g., 60 days past due), the system triggers a physical letter automatically.
I need an AR automation tool that can handle mailing physical collection letters to customers.
Which accounts receivable software can automate the printing and mailing of physical debt collection notices?
If you have a specific accounting or AR software you are currently using (like QuickBooks, NetSuite, or Salesforce Billing), let me know and I can tell you if it natively connects with a physical mailing tool like Lob or if a third-party integration is required.
