Baffled at reseller salaries

Posting this to see if others have a similar experience.

I work at a reseller in the UK here. One of the largest globally. I’ve always wanted to get into account management but the AMs here are paid a base of……

26k GBP + comms (10% of GP). So you’d need to do 2.5 revenue (300k GP average) to earn 46k.

Currently they are advertising roles for account management which are so tempting but I just can’t take such a pay cut

To earn good money is the best bet a vendor? Those who stay here for a decade earn loads but Tuesdays gone there I believe I’m not a graduate

Is this normal?!
