A Comprehensive List of ACH Error Codes and Resolutions

Anyone using the Automated Clearing House (ACH) may encounter an error code, also referred to as an ACH return code. In this knowledge base, we will cover potential errors that someone using ACH may encounter. We’ll cover all these error codes. Explain what each one means, its impact on you, your funding source, and how you can resolve the error.

Although using ACH for commercial real estate rent payments and collections offers convenience, significant time savings, automation, security, and reliability, sometimes errors can occur. Some factors are beyond our control, while others may come from unintentional actions we take. Understanding errors can help mitigate these issues.

Best Practices

To ensure a seamless experience, we recommend the following best practices.

1. Enable two-factor authentication to add an extra layer of security to your account.
2. Do not share your login information with anyone.
3. Monitor your transactions regularly and ensure that your correct payment amounts are always entered.
4. Do not mark the stratafolio.com domain as spam. This could prevent you from receiving important alerts we send out.
5. Landlord: Ensure invoices are always created prior to the ACH transaction due date.
6. Tenant: Set up your autopay and leave the amount blank to ensure you are paying the full invoice amounts. If you add an amount, ensure you update it when your lease escalations take effect to avoid underpaying your rent.

We hope this information provides you with the necessary details to ensure a pleasant ACH experience.
