How can you get Payroll to Pay contractors if you have a large PO contract that requires fast payout?

Really struggling here- for several weeks I cannot get my payroll out effectively bc QB keeps capping the amount I can payout, despite whats in my bank account. Respectively, that same bank account has been attached to QBO for years and they are now putting me through hoops to turn in bank statements, etc, while payroll was due LAST WEEK. I am going to end up sued and or losing a major government contract for the technical delays on the QB Payroll end. Why does QB limit what we can pay out if the amount is right there in our bank account?
