# Compliance Automation

> Ensure tax compliance with automated document tracking and validation

## Overview

Maintain regulatory compliance by automatically monitoring, extracting, and validating tax documents from SAT. Stay ahead of compliance requirements with real-time document tracking and automated validation workflows.

## Compliance Challenges

    Ensure all required tax documents are collected and stored properly.
  </Card>

  <Card title="Deadline Management" icon="calendar-clock">
    Track filing deadlines and ensure timely submission of tax documents.
  </Card>

  <Card title="Data Accuracy" icon="magnifying-glass">

## Automated Compliance Workflow

<Steps>
  <Step title="Continuous Monitoring">
    Set up scheduled extractions to monitor SAT for new documents regularly.
  </Step>

  <Step title="Document Classification">
    Automatically categorize documents by type, date, and compliance requirements.
  </Step>

  <Step title="Validation & Review">
    Run automated checks to validate document completeness and accuracy.
  </Step>

  <Step title="Alert & Reporting">
    Generate compliance reports and alerts for missing or problematic documents.
  </Step>

  <Step title="Archive & Retention">
    Store documents in compliance with legal retention requirements.
  </Step>
</Steps>

## Key Features

### Document Tracking

Track all tax documents across different categories:

* **CFDI Invoices**: Inbound and outbound invoices
* **Tax Status Certificates**: CSF documents
* **Tax Retention Documents**: Withholding certificates
* **Complement Documents**: Additional tax forms

### Compliance Validation

    * Check for missing invoice sequences
    * Validate document date ranges
  </Accordion>

  <Accordion title="Data Integrity" icon="shield-check">
    * Cross-reference document amounts with accounting records
    * Validate RFC and tax ID consistency
    * Check digital signature validity
  </Accordion>

  <Accordion title="Regulatory Requirements" icon="gavel">
