My customer tried to pay her invoice and QB wouldn't let her enter her bank information for an ACH payment. Is this a QB problem or something with her bank?

Let's ensure that the Pay Invoice feature is active when sending your invoices to your customers so they can pay instantly, Mdbrust.

Here's how:

1. Log in to your QBO account.
2. Go to the Gear Icon, then choose Account & Settings.
3. Navigate to the Sale tab.
4. Click Edit ✎ in the Online delivery section.
5. In the Additional email options for invoices ▼ dropdown, select Online invoice.
6. Click Save, then Done.

Afterward, send a new invoice to your customer. I recommend clearing your customer's browser cache to remove stored data that may be causing performance issues if they're still unable to enter their bank information. You can also suggest switching to a QBO-supported browser for better compatibility.

Also, guarantee that your customer uses the same currency in their bank account as on the invoice sent.

Speaking of payments, QuickBooks offers instant deposits, allowing you to transfer funds to your bank account in under 30 minutes. You can also schedule instant deposits to run automatically.
