TECHNICAL DEEP-DIVE

The Five-Stage Pipeline.

How Sophicor processes tax documents from upload to export. Security-first design. Sophia AI at each stage. Human professionals always in control.

The Pipeline

Document upload through automated export

STAGE 01

Intake

Secure upload portal. Client or staff uploads PDF. Virus scan. Encryption starts immediately.

STAGE 02

Extraction

Google Vision AI reads spatial data. Confidence scores assigned. Variance verification (in development).

STAGE 03

Validation

Logic checks run. Relationships verified. Low-confidence items flagged for review.

STAGE 04

Review

Preparer reviews only flagged items. All changes logged. Audit trail complete.

STAGE 05

Export

Validated data exports to your tax software or custom endpoint. Zero transcription errors.

Three Engines

The Vault — Security Engine

Full SSN values are stored in Google Cloud Secret Manager via our GAS workflow integration — your firm's data sheet contains only secret resource references, never the SSN itself. Sensitive fields are sanitized from API responses on the workflow path. Tax content lives in your firm's own Google Workspace, encrypted at rest by Google's standard encryption.

  • AES-256 encryption (government-standard)
  • Keys managed by you, not Sophicor
  • Zero data sharing with third parties
  • Private cloud residency by default

The Eye — Intelligence Engine

Powered by Google Vision AI. Reads documents spatially (not just text). Maps field locations, validates layout consistency, detects form variants, and auto-corrects for skew and rotation. Confidence scoring on every extracted field.

  • Spatial field mapping (not OCR alone)
  • W-2, 1099 variants auto-detected
  • Variance verification (in development)
  • Adaptive learning from corrections

The Robot — Automation Engine

Orchestrates the full workflow. Validates extracted data against business rules. Populates target tax software with zero manual handoff. Handles retries, error logging, and audit trails.

  • End-to-end orchestration
  • Multi-target export (tax software, API, custom endpoints)
  • Zero transcription errors
  • Complete audit logging
Sophia AI
Guides each stage of the pipeline

§7216 Compliance by Architecture

How Sophicor satisfies tax professional disclosure restrictions

Data Residency

Tax content stays in your firm's Google Workspace, not in Sophicor's storage. No shared servers. No multi-tenant database. Residency is a property of the system architecture, not a policy decision that can change.

Access Control

You manage who accesses what. Role-based access controls. Granular permissions. Audit trails showing every user action. No third-party override.

Encryption

Encryption at rest and in transit using Google's standard (AES-256). Tax content stays in your firm's Google Workspace — not in Sophicor's storage. SSN values are stored in Google Cloud Secret Manager; sensitive fields are sanitized from API responses on the workflow path.

Audit Trails

Complete logging of all access, modifications, and exports. Retention policies are yours to set. Ready for IRS examination or third-party audit at any time.

Technology Stack

Core Infrastructure

  • Google Cloud Platform (private deployment)
  • Cloud Functions (serverless compute)
  • Cloud Storage (encrypted at rest)
  • Secret Manager (key management)

AI & Document Processing

  • Google Vision API (spatial OCR)
  • Document AI (form parsing)
  • Variance engine for verification at scale (in development)
  • Custom algorithms (tax-specific validation)
