VIESAC VS ShellNewHandler

VIESAC's answer

VIESAC goes beyond basic VAT number validation by combining real-time checks, resilient fallback routing, and audit-ready evidence in one platform.

Unlike standard VAT lookup tools, VIESAC can automatically use alternative official registries when VIES is unavailable, helping businesses keep validation workflows running without interruption.

Each verification can be stored with timestamped evidence and generated as a professional PDF or XML certificate for audits, tax reviews, and internal compliance.

VIESAC also supports API integrations, WooCommerce, Google Sheets, EORI validation, monitoring, and country-specific business registries — making it suitable for both occasional checks and automated high-volume compliance workflows.

The focus is not only on answering “Is this VAT number valid?” but on providing reliable, reusable proof of the verification.

VIESAC's answer

VIESAC is built for businesses that need more than a simple VAT lookup.

It combines VAT and EORI validation, SmartRouter™ fallback checks, audit-ready PDF/XML certificates, monitoring, API access, and integrations in one platform.

A key advantage is reliability: when VIES is unavailable, VIESAC can use alternative official sources where supported, reducing failed checks and interruptions.

It also keeps structured evidence of each verification, so businesses can demonstrate when and how a VAT number was checked during audits, tax reviews, or internal compliance processes.

Compared with basic validation services, VIESAC focuses on the complete compliance workflow — from verification to evidence, monitoring, and automation — while remaining simple enough for occasional manual use.

VIESAC's answer

VIESAC is primarily designed for businesses that regularly sell to, buy from, or verify companies across borders and need reliable VAT compliance evidence.

Typical users include e-commerce businesses, wholesalers, logistics companies, automotive traders, accounting and tax teams, procurement departments, universities, public-sector organizations, and software platforms that need automated VAT or EORI validation.

It is especially useful for companies handling EU B2B transactions, reverse-charge sales, supplier onboarding, customer verification, or recurring compliance checks.

VIESAC serves both small businesses that need occasional verified checks and larger organizations that require API integrations, monitoring, audit trails, and higher-volume automated workflows.

VIESAC's answer

VIESAC started from a simple problem: VAT validation is easy when everything works, but real-world compliance is much more complicated.

Businesses need to know not only whether a VAT number is valid, but also when it was checked, which source confirmed it, what happened if VIES was unavailable, and whether they can prove the verification later during an audit.

VIESAC was built to solve that gap.

What began as a reliable VAT validation service gradually evolved into a broader compliance platform with audit-ready evidence, PDF and XML certificates, monitoring, API access, EORI validation, country-specific registries, and integrations for business workflows.

The goal has remained the same from the beginning: make cross-border VAT verification more reliable, easier to automate, and easier to prove.

VIESAC's answer

VIESAC is built around modern web and integration technologies, including REST APIs, webhooks, OAuth-based integrations, structured JSON/XML data exchange, and cloud-based automation.

The platform connects with official VAT, EORI, tax, and business registries and supports integrations with e-commerce, spreadsheets, automation platforms, and other business systems.

VIESAC is designed to work both as a standalone web application and as an API-first compliance service that can be embedded into existing business workflows.

VIESAC's answer

VIESAC is used by businesses and organizations across several sectors, including automotive and vehicle trading, logistics and freight, wholesale and distribution, e-commerce, accounting and tax advisory, legal services, universities, and public-sector organizations.

The platform is particularly relevant for companies that handle frequent cross-border B2B transactions and need reliable VAT or EORI validation together with audit-ready evidence.

VIESAC is also used by larger organizations evaluating API-based or automated compliance workflows for higher-volume verification.
