Find largest payee in a table

I have a finance tracker in excel with some sample data that I'm trying to find stats about.

each transaction has fields shown

How would I find the largest payee based on the amounts in column D (eg. who paid me the most money).

I can find the sum of one payee using index and sumif: (finances2019 being the transaction table)

=SUMIF(INDEX(Finances2019,,8),"Cisco",(INDEX(Finances2019,,4)))

But how can I search through the sum of each one and find the max?
