Let me share insights about why your client's invoice payment is still in review.
If you're a new user, your first set of payments will be deposited in up to 5 business days. Since we are still setting up your account, it may take some time. Once the first payment is processed, subsequent payments will be deposited into your bank account much faster.
Payments processed before 3:00 p.m. PST in QuickBooks Online (QBO) will be deposited to your bank account the next business day, and those received after 3:00 p.m. PST will be deposited within two business days.
Payments made before 3 p.m. PST should be in your bank account in two business days if you don't have a next-day deposit. We'll start the deposit the next business day if you process payments after 3 p.m. PST.
I'd recommend contacting our Merchants Services Support Team if the payment is still not deposited within the specified time frame. Since they can request account information, this team is the best resource for such questions. They can also check the payment's status and investigate why it hasn't yet been placed into your account.
