Why Quick Start: Fix E-Invoice Errors Matters
Stop Wasting Time on XML
Without our Fixer, when you get validation errors you need to:
- Understand what each error code means
- Open the XML in a text editor
- Find the right element to change
- Know the correct format/code to use
- Re-validate to check if it worked
This can take hours if you're not an XML expert. Our Fixer does it in seconds.
We Never Change Business Data
Our Safety Promise: We only fix technical errors. We will NEVER change:
- Amounts, totals, or VAT calculations
- VAT IDs or company registration numbers
- Bank details (IBAN, BIC)
- Dates that affect legal obligations
Full Audit Trail
Every fix is logged. You get a complete Evidence Pack showing exactly what changed, with before/after values and SHA-256 verification hashes.

How the Fixer works under the hood
The Fixer classifies every error into three categories: auto-fix (structural issues corrected automatically), input-required (missing data that needs your input), and blocked (financial fields never modified). After remediation, the result is revalidated through KoSIT to confirm genuine compliance.
