A: Hi,
Yes, you can do that.
You need to configure Stripe.

You can configure Stripe invoices to allow clients to pay exclusively via ACH, without enabling credit card payments. Stripe provides the flexibility to customize payment methods for each invoice. Here's how you can set this up:

Disable Default Payment Methods: By default, Stripe enables several payment methods, including credit cards. To restrict payments to ACH only, you'll need to disable other payment methods in your Invoice template settings.

Enable ACH Direct Debit: Ensure that ACH Direct Debit is activated in your payment methods settings. This allows clients to pay invoices directly from their bank accounts.

Configure Individual Invoices: When creating an invoice, you can specify which payment methods are available. Set ACH Direct Debit as the sole payment option for that invoice.

By following these steps, your clients will receive invoices that permit payments exclusively through ACH, effectively disabling the credit card payment option.

Thank you
