The Challenge & The Solution

Why Unchecked Invoices Threaten Your Bottom Line

Tax auditors focus heavily on incoming invoices during tax audits. A missing VAT ID, an incorrect address, or a math mismatch leads to retroactive rejection of input tax deductions – plus interest penalties.

⚠️

The Problem: Manual Inspection Fails

• 19% Cashflow Loss: Retroactive rejection of input tax claims by tax auditors.
• Blind Spots: Manual 100% inspection of thousands of invoices is impossible for accounting teams.
• Liability Trap: Missing VAT IDs or unverified foreign suppliers expose companies to tax fraud liabilities.

🛡️

The Solution: Digital Input Tax Shield

• Real-Time Verification: Hooks directly into email webhooks, REST APIs, or ERP systems.
• Audit-Proof Archiving: Instant BZSt JSON responses saved for tax audits (§ 18e German VAT Act).
• 1-Click Resolution: Generate automated vendor correction emails with precise legal references.
