building document extraction tool for wealth managers and trying to figure out pricing model option A: per-seat (e.g. $X per user per month) option B: usage-based (e.g. $X per document processed) option C: hybrid (base fee + overage charges) for context, the value prop is saving analysts 6-8 hours per week on manual document work im leaning toward usage-based because its easier for customers to start small and prove ROI, but ive heard enterprise buyers prefer predictable seat-based pricing what have you seen work in fintech / financial services SaaS?
