Quick Start: Fix E-Invoice Errors
Invoice Navigator's Fixer tool automatically corrects technical errors in your e-invoices, making them compliant in seconds.
The Fixer tool works in four simple steps:
- Upload - Drop your invoice XML file (no signup needed to try)
- We Find Issues - We validate against all rules and categorize errors
- We Fix Them - Auto-fixable errors are corrected automatically. If we need info, we ask simple questions.
- Download - Get your compliant invoice plus a full Evidence Pack
What Happens to Your Data?
Your invoice is processed in secure EU servers. After processing:
- Fixed invoice: Available for download immediately
- Evidence Pack: Stored securely for retrieval (Pro/Business)
- Original file: Deleted after processing
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.

Frequently Asked Questions
- What errors can you fix automatically?
- We auto-fix technical errors like date format issues (DD-MM-YYYY → YYYY-MM-DD), missing scheme identifiers, invalid code values, and XML structure problems. See E-Invoice Remediation for the full list.
- What if you need information from me?
- For some errors, we need data that isn't in the invoice—like a buyer reference or payment terms. We'll ask you simple questions (no XML editing) and apply the fix for you.
- Can you change amounts or VAT?
- No, never. We only fix technical/formatting errors. If your invoice has calculation errors, those need to be fixed in your source system.
- Is my data secure?
- Yes. Processing happens on secure EU servers. Your original file is deleted after processing. Fixed invoices and Evidence Packs are stored securely for retrieval.
- How much does it cost?
- Checking, previewing and fixing are free and need no account. The first verified download every 30 days is free. After that a verified download is €1.90 per invoice, or €9 a month for as many as you send. See Pricing for details.
