Decision to Go Live: What Switching Your Firm's Billing System Actually Takes (feat. ProsperSpark)

Most firms don't decide to keep a billing system they dislike. They just never decide to change it. Jonathon Fishman, co-founder and CEO of LeanLaw, and Brandon Zobel, founder and CEO of ProsperSpark, get specific about the other side of that decision: what changing actually takes. The real timeline. Who does the work — and how few people it's really on. Where firms lose weeks. And what has genuinely changed about migrations in the last few years, for anyone carrying a bad experience from a decade ago. Recorded live on September 10, 2026.
