Greek Compliance & AADE Integration
This skill transforms OpenClaw into a Greek accounting compliance specialist, handling AADE submissions, VAT calculations, payroll processing, social security contributions, and regulatory deadlines specific to Greek business operations.
Setup
# 1. Set data directory export OPENCLAW_DATA_DIR="/data" # 2. AADE credentials (required only for submitting filings — preparation works offline) export AADE_USERNAME="your-aade-username" export AADE_PASSWORD="your-aade-password" # 3. Ensure dependencies which jq curl || sudo apt install jq curl # 4. Create compliance directories mkdir -p $OPENCLAW_DATA_DIR/compliance/{vat,efka,mydata,e1,e3} Security notes: AADE credentials are only used when submitting filings to the government portal All submissions require human approval (four-eyes workflow: preparer ≠ approver) Filing preparation, VAT calculation, and report generation work fully offline Credentials are never stored on disk — always use environment variables

Common AADE Integration Issues
Connection_Errors: symptoms: "TAXIS login failures" solutions: - "Check internet connectivity" - "Verify tax credentials" - "Check 2FA token validity" - "Retry with exponential backoff" Validation_Errors: symptoms: "XML submission rejected" solutions: - "Validate against current AADE schema" - "Check all mandatory fields" - "Verify VAT calculations" - "Confirm digital signature validity" Rate_Limiting: symptoms: "Too many requests error" solutions: - "Implement request queuing" - "Batch multiple submissions" - "Spread submissions across day" - "Use off-peak hours for bulk operations"
Payroll Calculation Issues
Hour_Tracking_Errors: symptoms: "Overtime calculations incorrect" solutions: - "Verify Greek labor law compliance" - "Check holiday calendar updates" - "Validate employee contract terms" - "Review collective agreement rules" Social_Security_Errors: symptoms: "EFKA contribution mismatch" solutions: - "Update contribution rates quarterly" - "Check salary caps and thresholds" - "Verify employee insurance category" - "Review disability/age adjustments"
Success Criteria
A successful Greek compliance system should achieve: ✅ 100% AADE deadline compliance ✅ 99.9% VAT calculation accuracy ✅ Real-time myDATA invoice submission ✅ Zero payroll calculation errors ✅ Complete audit trail for all transactions ✅ 80% reduction in manual compliance work ✅ Integration with all major Greek banks ✅ Automated social security submissions
Professional Responsibility
This skill assists with Greek tax compliance but does not replace professional accounting advice Users must verify all calculations against current Greek tax law Regular updates required as Greek tax regulations change Professional liability insurance recommended for accounting firms Final responsibility for tax compliance remains with the business owner/accountant
Regulatory Updates
Greek tax law changes frequently - skill requires regular updates AADE may change API specifications or requirements Social security rates and thresholds change annually Municipal tax rules vary by locality and change regularly Users must monitor official government announcements Remember: This skill enhances accuracy and efficiency but professional oversight remains essential for Greek tax compliance.
