As Senior Accounting Manager, B2B Revenue, you'll own revenue accounting for Function Health's contract-driven business: memberships offered through employers and organizations, brand and channel partnerships, and gift card programs, along with the direct costs tied to each. It's a lower-volume, higher-dollar business that the company is investing to grow, and it's a build role. You'll design how this business runs from contract to cash: how agreements are reviewed, how customers are onboarded and invoiced, and how much of it runs without manual effort.

The work sits upstream, closer to the deals and initiatives that shape what ends up on the books.

You will also bring an accounting perspective to new initiatives across the company. As Product, B2B, and Partnerships teams develop new programs, pricing models, and deal structures, each one benefits from accounting input before it's built. You'll review product requirements documents and agreements, assess the ASC 606 implications, flag operational risks, and offer a point of view on how an initiative could be structured to reduce manual effort.

You'll thrive here if you've built a B2B revenue process before, have worked through enough nonstandard contracts to recognize issues early, and instinctively look for creative ways to take manual work out of billing and collections.

You will report to the Senior Director, Revenue Accounting & Operations and operate as a senior leader within a lean, high-autonomy team. B2B revenue accounting is still being built, so you'll have real influence over how it works, from how contracts are structured and reviewed to the processes and systems that carry them through to invoicing and revenue, rather than stepping into a process someone else already defined.

It's a strong fit if you're energized by ambiguity, confident building relationships well outside of accounting, and motivated by the opportunity to build something meaningful in a fast-paced, high-growth environment.
