Pro keeps your data sovereign. Forge automates your existing tax stack. Run both — and the Variance Engine starts comparing Sophicor's calculation against your tax software, every return, every cycle. The foundation for becoming the platform of record across all return types.
NexFile™ Pro is the firm's brain — every client, every document, every calculation. NexFile™ Forge is the firm's hands — populating your existing tax software without manual entry. Run them together and you get something neither product gives you alone: the Variance Engine, comparing the two calculations until your existing tax software is no longer load-bearing.
Sophia AI extracts every field from W-2s, 1099s, K-1s, 1098s, and all standard IRS forms. Inside your firm's own Google Workspace. Confidence-scored. Audit-trailed.
The local agent populates your existing tax software automatically. Hands-free workflow. Zero transcription errors. One-click export.
Sophicor calculates. Your tax software calculates. The Variance Engine tracks the delta — every return, every cycle. As variance approaches zero, the question of which platform is load-bearing answers itself.
The Variance Engine only exists when Pro and Forge run together. It is not sold separately. It is the strategic moat.
