Lassie is a fast-growing, venture-backed AI billing platform whose agents work inside your practice management system to post payments and work denials. It is a genuinely different model to a done-for-you team, so the right alternative depends on whether you want to keep billing in-house or hand it off entirely. Here is an honest comparison.

Practices choose a service when they want billing off their plate entirely rather than supervising software.

If you want billing handled for you rather than automated in-house, a done-for-you service like PracticeAlpha is the natural alternative.

Lassie is AI billing software: its agents work inside your practice management system while your team supervises. A service like PracticeAlpha is the opposite model, a team that runs billing for you. That distinction is the main thing to weigh.
If you have staff to oversee automation and want to keep billing in-house, AI software can work well. If you want billing off your plate with someone accountable for the result, a dedicated service fits better. A free AR analysis on your numbers makes the trade-off concrete.
