Oh Quickbook Reply Bullsh**it. Here's the truth. It all depends on (1) how knew you are with them (2) how much your transferring and what the payment is for. First thing you should never do is transfer large amounts of money using their payment service, thats going to be a large flag to have Intuit steal and/or hold your money for as long as they want giving you bs reasons for holding it. You should only do small under $50 transactions for the first 3-6 months. Never go into the thousands of dollars, thats a flag for getting your account locked. Wait for the customer to write you a check thats ceritified. Dont be so greedy and impatient to do anything electronically in large amounts. Doing any sort of transaction electronically only means it can be taken away from you at anytime until the money is in your bank account and after that. Whether is a credit card dispute or a bank ach dispute. You dont want to set yourself up for that. 

When you send an invoice don't include what the product or services is for because Intuit has access to looking at your invoice and see what its for. If they dont like what your doing you'll get your account locked. Intuit will always string you along to make you think it wasnt them when the whole time it is them. A bank transfer like Zelle Payments should be instant. When you use Zelle, the payment is instant. So if Zelle can do it, then PayPal should be able as well. Cut off time with Intuit is 3 pm Western time. The transfer should take NO LONGER than 3 business days. Anything after that, then Intuit is playing games. If they start to play their games, tell the customer to do a ACH dispute for non authorized and get a paid a different way.
