VIESAC helps EU B2B businesses validate VAT numbers, generate VIES audit certificates, and store compliance proof for cross-border 0% VAT invoices.
VIESAC is a cloud service for EU VAT number validation, VIES audit proof, and compliance storage. It helps B2B sellers, accountants, SaaS platforms, e-commerce stores, and ERP integrations verify customer VAT numbers and keep timestamped evidence for tax audits.
The service generates downloadable PDF and XML certificates with validation details, consultation numbers when available, requester information, invoice or order references, and a long-term audit trail. VIESAC is especially useful for companies applying 0% VAT on intra-EU B2B transactions and needing reliable proof that a VAT number was checked at the time of sale.
VIESAC also provides an API for automated validation from WooCommerce, Magento, ERP, accounting, or custom systems. It includes retry logic, monitoring, and fallback handling for cases when official VIES services are temporarily unavailable.
Getwebstack is for development teams that implement a lot of different projects. It can help outsourcing companies, accelerators, freelancers, or dev studios to develop fast. It is also for individuals that want to test a technology or an idea for a startup with a quick setup and deployment. Getwebstack provides a complete solution that covers all the technical aspects of a web app. It has an affordable monthly subscription instead of an expensive one-time payment.
