About this Gig
Your ViDA / KSeF invoice just got rejected by the tax portal. You have 48 hours to file or face 500+ in daily penalties. Your ERP exported 2,000 invoices, but validation errors are blocking submission.
Real-time tax systems reject messy data. Issues: invalid VAT IDs, date mismatches, tax code errors, duplicates, incompatible XML formats.
Penalties compound daily. Tax authorities freeze VAT recovery, halt B2B sales, trigger audits. Compliance is mandatory.

FAQ
How do I know you understand ViDA/KSeF validation?
I specialize in real-time tax system validation. I've cleaned 5,000+ invoices across ViDA, KSeF, and Peppol. Message me and I'll share anonymized portfolio examples showing before/after errors. Happy to jump on a quick call to discuss your specific validation issues.
What if my ERP exports a format you don't recognize?
Common export formats: CSV, Excel, XML, JSON. If your ERP uses an unusual format, message me with a sample file (no real data needed). I can handle most formats. If it's truly custom, I'll let you know upfront—no surprises. Most clients send CSV or XML and we're good to go in 5 minutes.
Will the tax portal accept the file after you clean it?
I validate against official ViDA/KSeF/Peppol schema. 95% of files pass portal validation after cleaning. Standard package includes a 'validation guarantee' if rejected after my cleaning, I re-check free. Bottom line: I've never had a buyer need that guarantee, but it's there to remove your risk.
How long does 12-hour delivery actually take? Can you be faster?
12 hours = thorough without rushing. I audit every row; accuracy matters more than speed. If you're urgent (filing in 6 hours?), message me FIRST. I can sometimes do 6-hour expedited for +€10. But 12 hours is fast enough for most filing deadlines; you'll have your file by next morning.
Do you handle XML schema conversion (e.g., SAP to KSeF)?
Yes. If your ERP exports one schema and your tax authority requires another, I map and convert. Examples: SAP Peppol, Oracle KSeF. Standard and Premium packages include this. Basic is CSV-only. Message me with your source + target schema and I'll confirm the scope.
