85% of Fortune 500 companies choose Fintua

Managing client indirect tax compliance at scale is complex
Every client is different
Source data varies by ERP, marketplace and file format, manual consolidation doesn’t scale
Many regimes, many calendars
VAT, OSS/IOSS, eInvoicing, VIES/EC Sales and Intrastat have different periods, deadlines and files to generate
Handoffs and cover
Reviewer and approver chains vary by client, while holiday cover and escalations are easily missed in email
Evidence on demand
Clients and authorities expect invoice level traceability and quick, defensible responses
Margin pressure
Spreadsheets and ad hoc scripts consume capacity and increase rework risk
