I think scaling with revenue is appropriate (as you're aligning incentives), as long as it has a ceiling near the monthly fully loaded cost of a Controller role (which is right around ~$12,500 in the US). At that point (having a need for a Controller role), the customer should be doing between $40MM-$50MM in ARR/annual turnover. With that said, Finmark should expect to have to provide more value to a customer than a single Controller role would. This also might help with encouraging CFOs not to attempt to build finance fiefdoms (tools > headcount).
