I want my invoices to automatically have the ACH payment button on but it won't let me do it in settings. Help

I'm here to help you turn on the ACH payment button in your invoices, @erin39.

To show the pay invoice button, you have to link your ACH payments account to QBO and choose the payment method on the invoice. If you haven't already, you'll need to sign up for QuickBooks Online Payments. If you already have, you only need to connect your existing account in QBO. 

The process will take about 24-28 hours, and you'll be notified via email once it's approved. From there, you can start sending invoices with the Pay Now button. 

Then, here's how to turn on and send online invoices in QBO:

1. Click the Gear icon.
2. Select Account and Settings.
3. Choose Sales on the left.
4. Pick within Online delivery
5. Hit the drop-down under Additional email options for invoices and choose Online invoice.
6. Tick Save.

For more details, about the process, please see this article: Take and process payments in QuickBooks Online.

Also, to know when QuickBooks deposits customer payments into your bank account, you may check out our deposit times for QuickBooks Payments page. 

Let me know how it goes and leave a reply below if you have further concerns about invoice payments. I want to make sure you're taken care of, and I'm here to help you anytime. Take care always.

Is there a setting to get this checkbox selected by default as opposed to having to click it manually on every invoice?

Good morning, @JardumCEO.
