New client for me.

in 2023, 22K W-2, one child, single.  EIC and child credits resulted in a refund of 7K. Tax prep was $850 + $39 refund transfer fee.

While his partner, same basic situation, with similar refund was charged $400

There is expertise and we know it when we see it. But is $850 for preparing a simple W-2 about right, exorbitant, or a value?
