Could you build this?
Partial The workflow UI (requests, tasks, status boards, and document linking) is vibe-codeable, but a credible version needs accounting and audit domain expertise, Excel and Word add-ins, and SOC 2 compliance. Its AI audit reasoning with source-linked citations is also hard to get right.
What it would actually take: The stack would be a multi-tenant web app with a task and workpaper data model, plus Office.js add-ins for Excel and Word and LLM pipelines that extract and cite evidence from client documents. The hard parts are audit-grade accuracy, reviewer sign-off workflows, and security certification. That requires audit practitioners to define the workflows, plus security and compliance engineers to pass SOC 2 and handle GDPR obligations.
