For anything over $50,000, go with a Bank Wire Transfers.

Banks (Best for Business). 

Not Credit Unions (Great for Personal).

A Bank will charge you about 1% of the Amount, which will get you a much better deal than DirectPay (at 3%).

Shop around for Banks to find the cheapest Wire Transfer Fee. 

Make SURE these Transactions are going into your Business Bank Account and NOT your Personal Bank Account.
