Context

A.Tax is where companies run financial and tax calculation together rather than mailing workbooks around. It carries a formula engine at Excel's level of expressiveness, live collaboration between people working in the same numbers, and an audit trail behind every value on the screen.

I advise on its technical architecture. That audit trail is the reason the product exists: in tax work, a number nobody can trace is not a number, it is a liability.


Working on something like this?

Thirty minutes, no charge. If I am not the right person for it I will say so on the call.
