Industries/Tax advisory
A fifty-person tax firm in Shinjuku where the expertise that would have gone into a specification went straight into the application instead.
The situation
A tax practice runs on judgement encoded into repeatable work: estimating an inheritance liability, simulating an incorporation, quoting a retainer, tracking a withholding special case. Every firm does these slightly differently, and the difference is the firm's expertise.
Commissioning that as software means writing the specification — which means an adviser explaining tax law to a developer, then checking whether the developer understood. For a fifty-person firm, that translation cost is usually more than the software is worth.
So the advisers skipped it. They built the tools themselves.
Who built it
Five practising tax accountants
Not a digital team, not an intern — advisers with live client work, building between meetings. The person who knows what the tool should do turned out to be the person best placed to build it.
Twelve applications in the first months on the platform, with no specification written and no developer to brief.
What they built
Professional firms lose most of the value in translation. This removes the translation step.
