Letvægts brugerdefinerede formler
Use =VIESAC(A2:A50, "status") or =VIESAC_RATE("DE", "standard_rate") for on-the-fly verification that never consumes your immutable audit certificate quota.
Audits i batch
Audit up to 200 selected rows per run. The sidebar automatically groups API requests into batches of 25 to respect Google Apps Script execution timeouts and rate limits.
Referencer og certifikater
Every audit creation requests an official tax authority consultation number and generates a cryptographic SHA-256 sealed PDF certificate for tax audit defence.
90-dages kontrol og historik
Configurable age policy flags rows needing re-verification without overwriting past proof. Old certificate links are automatically preserved in the VIESAC History tab.
Adgang for 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.

| =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 |

Hvorfor momsvalidering i massevis hjælper økonomiteams
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.
EU-pakken VAT in the Digital Age (ViDA) digitaliserer grænseoverskridende momsrapportering fuldt ud fra 2030. Et tidsstemplet auditspor i regneark giver søgbar dokumentation til intern gennemgang og skattekontrol.
Ofte stillede spørgsmål om momsvalidering i Google Sheets
Bruger =VIESAC() mit certifikatforbrug?
Nej. =VIESAC() udfører en let kontrol og opretter ikke en audit. Credits bruges kun ved bevidst oprettelse af en ny audit i sidepanelet.
Er API-nøglen sikker i et delt ark?
Nøglen skrives ikke i celler eller formler. Dokumentegenskaber deler dog forbindelsen med tilføjelsesbrugere i dokumentet; brug en separat nøgle, der kan tilbagekaldes, pr. team eller kunde.
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.
Hvilke lande og registre understøttes?
Tilføjelsen bruger VIES for EU’s 27 medlemsstater, HMRC for Storbritannien, Swiss UID og Brønnøysundregistrene for Norge.
