This solves a real pain: manual data entry from client documents is tedious and error-prone. The gap is that existing portals are generic or expensive for small firms. Hard part is distribution—convincing accountants to switch from email/secure upload to a new workflow. Also need to integrate with many tax software formats. For this to work, you need a champion firm to co-design and a simple integration with one major tax software (e.g., Drake, UltraTax) to start.

Accountants spend 30-50% of tax season on data entry. Existing portals like ShareFile lack AI parsing. Tax software vendors want to reduce friction for users.

Clear pain, existing budget Manual entry is hated

Why now

Heuristic scoring based on model judgment, not factual measurement.

AI parsing is production-ready Remote work drives portal need No AI-native portal for small firms

The market is ready for AI-powered document intake, but adoption hinges on ease of integration and price. Timing is good for a low-cost alternative, but distribution remains the bottleneck.
