VIESAC introduces Bulk Audit—a scalable solution for mass VAT validation built to meet strict ViDA (VAT in the Digital Age) expectations and simplify tax data hygiene for EU enterprises. Whether you are closing a quarter, onboarding a partner list, or refining master data ahead of EU digital reporting reform (incl. 2026 ViDA milestones), checking VAT IDs one by one does not scale. Bulk Audit in VIESAC is a European VAT validation tool at list scale—turning that grind into a single workflow toward a single source of truth for VAT.
Why it matters now — real-time tax governance: With the EU moving towards real-time digital reporting, maintaining tax data hygiene is no longer optional. You supply the VAT IDs; we run the same official VIES pipeline as every other check—complete with VIES validation certificate output where status allows, full history, and optional monitoring. That is future-proofing for ViDA in day-to-day operations.
No separate rules, no shadow database: every queued row becomes a real audit in your account—an audit-ready evidence trail aligned with what you build via single checks and the API, yielding AI-ready structured tax data (time-stamped, consistent fields) for analytics and downstream automation. It is your bridge to continuous compliance and closing the compliance gap between spreadsheets and what tax authorities expect.

Closing the compliance gapManual work vs Bulk Audit
A side-by-side look at why teams graduate from ad-hoc lookups to Bulk Audit inside VIESAC—and start eliminating ghost VAT IDs that linger in CRM and ERP exports.
| Feature | Manual VIES check | VIESAC Bulk Audit |
|---|---|---|
| Speed | 1–2 minutes per ID (copy, paste, wait, screenshot…) | Hundreds queued in seconds |
| Audit trail | Browser screenshots, notes in Excel—if nothing gets lost | Audit-ready evidence trail—time-stamped certificates & history in one place |
| Reliability | Human-error prone (typos, wrong country, missed rows) | Smart input normalization, delimiters & row-level status |
| Ghost VAT IDs | Stale spreadsheets hide deactivated or never-valid numbers | Eliminating ghost VAT IDs—live VIES batch processing exposes invalid rows immediately |
| ViDA readiness | ❌ Poor — hard to prove continuous due diligence | ✅ Ready for digital reporting — same ViDA-grade pipeline as every audit |
Stack fit: Bulk Audit and CSV uploads sit alongside everything else in your account. Teams on SAP, Oracle, Salesforce, or Odoo typically export partner VATs from the ERP or CRM, run them through Bulk Audit or the REST API, and land the same certificates in VAT Validation & Audit. WooCommerce merchants get checkout-grade validation via our storefront extension; Make users wire VIESAC into existing automations without writing middleware.
1Single source of truth for VAT— what Bulk Audit delivers
Bulk Audit is future-proofing for ViDA at operational speed: teams that treat VAT as risk, not paperwork, get one place where VIES batch processing results land beside API and manual checks. You focus on the list; VIESAC applies smart input normalization, enforces plan limits, queues work, and returns per-row status so finance and engineering share the same audit-ready evidence trail.
| Capability | What you get |
|---|---|
| Official VIES checks | Each queued row runs through the same validation engine as single VAT checks—including evidence you can show in an audit. |
| Batch-friendly input | Paste one VAT per line or upload a CSV (comma or semicolon) up to 5 MB—ideal for exports from ERP, spreadsheets, or ticket systems. |
| Row-level transparency | See which rows were queued, skipped as invalid, or deferred when your monthly allowance is reached—no silent drops. |
| Optional monitoring | From CSV, attach a monitoring period per row so critical partners stay on your radar after the first successful check. |
| Email when the run finishes | Turn on completion email to close the loop without refreshing the dashboard. |
2Smart input normalization— paste, CSV, verify partner VAT IDs at scale
Check EU VAT numbers in bulk without hand-fixing every cell: quick mode accepts full VAT numbers (with country prefix), one per line. CSV mode auto-detects comma or semicolon, maps headers, and falls back to a fixed column order when no header row is present—classic VAT data cleansing guardrails before a single mass VIES audit job fires. Together, that is smart input normalization that keeps AI-ready structured tax data consistent for whatever consumes your exports next.
| Column (CSV) | Purpose |
|---|---|
vat | Full VAT with country prefix, or number + separate country column. |
country | ISO country code when the VAT cell has no prefix (optional if VAT includes country). |
monitoring | day, week, month, quarter, year, or none—links to VIESAC monitoring after validation. |
invoice / order | Your internal references—carried into the audit trail for traceability. |
comment | Free-text context for your team (not sent to VIES). |

3Real-time tax governance— fair queuing & ViDA-ready scale
Bulk Audit respects your subscription the same way manual checks do—transparent real-time tax governance for capacity: if a list holds more valid rows than your remaining monthly validations, VIESAC processes the first tranche immediately, labels the remainder, and keeps you in control of ViDA compliance spend—upgrade or resume next cycle without guesswork.
Malformed lines are surfaced as skipped rows before they touch your allowance.
Large jobs run asynchronously—your team can keep working while audits complete.
Everything lands in VAT Validation & Audit with certificates where status allows—aligned with SAP, Oracle, Salesforce, and Odoo via the API, with ready-made paths for WooCommerce and Make.
Mass EU VAT validation — close the compliance gap in one run
VIESAC turns list chaos into an audit-ready evidence trail: one upload, hundreds of official checks, eliminating ghost VAT IDs that quietly poison CRM and ERP exports—future-proofing for ViDA without sacrificing speed.
