Spent tonight reading and commenting on 3 more invoice threads on IH, and the pattern was weirdly consistent. Nobody wanted more accounting features, they were stuck on the moment an invoice goes overdue and the next email starts feeling personal.
That is the narrow slice I'm building ChaseFlow around. If you want to see it, https://chaseflow-ten.vercel.app?utm_source=ih&utm_medium=post&utm_campaign=ih-roundup-2026-06-02
Curious if other founders see the same thing, invoice creation gets automated first, overdue followup still sits on the founder's to-do list.
