Good morning, @jz590873.
I hope you're enjoying your day so far.
There is a %1 fee if a customer pays through an invoice using ACH bank transfer. The maximum amount you can accept per day is $2,000. You can check out Accept Credit Card Payments for more details about our fees and rates.
Additionally, if you're new to payments, your first payments may take a bit longer while your accounts are being set up. Going forward, the payment process is much faster. See the details outlined in: Take and process payments in QuickBooks Online.
Please let me know if you have further questions or concerns. I'll be here to guide you back to business every step of the way. You can always count on the Community anytime you need assistance. Take care!
