You should consider having a free Melio account to sync with QBO as an alternate option. While Melio doesn't restrict payment amounts, your bank may have its own limits on the amount of money you can pay. It's important to check with your bank before making a big payment to avoid any setbacks. You can also get a $100 cashback to pay the first bill.
