Toegang voor teams
API keys are stored strictly in Apps Script Document Properties, never in cell contents. Uses least-privilege Google OAuth scopes limited to the current spreadsheet.
Handleiding Google Sheets-formules
VIESAC provides two high-performance custom functions built specifically for Google Sheets syntax.
| Syntaxis | Functie | Voorbeeld |
|---|---|---|
| =VIESAC(A2:A50, "status") | Returns validation status (VALID, INVALID, NOT_FOUND) for a range of VAT numbers. | VALID |
| =VIESAC(A2:A50, "valid") | Returns a boolean TRUE or FALSE. Perfect for IF() statements and conditional formatting. | TRUE |
| =VIESAC(A2:A50, "source") | Returns the official registry consulted: VIES, HMRC, UID, or BRREG. | VIES (DE) |
| =VIESAC(A2:A50, "checked_at", $Z$1) | Returns the ISO timestamp of the validation. Supports an optional deterministic refresh key cell. | 2026-09-23T10:15:00Z |
| =VIESAC_RATE("DE", "standard_rate") | Looks up the statutory VAT rate for any EU or partner country (standard, reduced, super-reduced). | 19.00% |

Waarom btw-validatie in bulk in Google Sheets financiële teams helpt
For finance managers, tax accountants, and billing operations, Google Sheets and Excel remain the undisputed nerve centers for managing master customer lists, vendor onboarding, and monthly VAT returns. However, verifying hundreds of cross-border VAT identifiers manually through the European Commission ec.europa.eu portal is notoriously inefficient: it requires solving reCAPTCHAs, typing one identifier at a time, and taking manual screenshots for proof.
Under European tax jurisprudence and national legislation (such as German UStG § 6a or French CGI Art. 262 ter), a business applying 0% VAT on intra-community supplies bears the legal burden of proof. If a foreign B2B buyer's VAT number was deregistered or invalid on the invoice date, tax authorities can retroactively assess the unpaid tax plus severe penalties against the seller during an audit.
The VIESAC Google Sheets Add-on bridges this compliance gap. By bringing direct API connectivity into Google Workspace, finance professionals can perform batch validations across 27 EU member states, the United Kingdom, Switzerland, and Norway in seconds. Unlike generic regex checkers, VIESAC communicates directly with upstream governmental endpoints, obtaining official consultation reference numbers.
Het EU-pakket VAT in the Digital Age (ViDA) maakt grensoverschrijdende btw-rapportage vanaf 2030 volledig digitaal. Een tijdgestempeld auditspoor in uw sheets biedt vindbaar bewijs voor interne beoordeling en belastingcontroles.
Veelgestelde vragen over btw-validatie in Google Sheets
Verbruikt =VIESAC() mijn certificaattegoed?
Nee. =VIESAC() voert een lichte controle uit en maakt geen audit aan. Credits worden alleen gebruikt wanneer u vanuit de zijbalk bewust een nieuw audit aanmaakt.
Is de API-sleutel veilig in een gedeelde sheet?
De sleutel staat niet in cellen of formules. Documenteigenschappen delen de verbinding met add-ongebruikers in dit document; gebruik daarom per team of klant een eigen intrekbare sleutel.
How does the 90-day recheck recommendation work?
European tax auditors expect ongoing verification of active trade partners. When an audit row is older than your configured threshold (default 90 days), the add-on highlights the status as "Recheck recommended". Crucially, re-auditing preserves the previous audit record and certificate URL in the "VIESAC History" sheet so past evidence is never erased.
Welke landen en registers worden ondersteund?
De add-on gebruikt VIES voor de 27 EU-lidstaten, HMRC voor Groot-Brittannië, Swiss UID en Brønnøysundregistrene voor Noorwegen.
