VIESAC turns Google Sheets™ into a VAT compliance workspace for accountants and finance teams. Validate EU VAT numbers, create traceable audits for new rows, and reopen existing VIESAC references without consuming another audit credit. Run an explicit recheck when fresh evidence is required. Each audit can link to a PDF certificate and XML evidence record. Use VIESAC formulas for validation and the sidebar to manage rows, audit status, and evidence links.
