# How should platforms communicate with their connected accounts regarding the ACH Direct Debits migration?

As a platform, the ACH Direct Debit migration will impact both your main platform account and all connected accounts. Your connected accounts don't need to understand the technical implementation details, but they should be informed about how this change affects their day-to-day operations.
We suggest sending a clear update to your connected accounts that focuses on [key differences](https://docs.stripe.com/payments/ach-direct-debit/migrating-to-new-apis#new-features) between legacy ACH Direct Debits and the new APIs such as:
* Changes to [Settlement timing](https://docs.stripe.com/payments/ach-direct-debit#timing) and funds availability
* [Bank Account Verification Updates](https://docs.stripe.com/payments/ach-direct-debit#timing): Outline any differences in how bank accounts will be verified going forward
* [Mandate Email Process Modifications](https://docs.stripe.com/payments/ach-direct-debit#mandates): Describe changes to how authorization emails work.
