Building a script to calculate EU VAT and track the €10,000 OSS threshold takes a weekend. However, legally filing returns, holding power of attorney, and communicating with national tax offices across 27 EU countries requires humans and regulatory licenses.

Sovos
Sovos is not software you buy for its UI; you pay for tax liability offloading, maintained rate tables, and automated regulatory filings across tens of thousands of global tax authorities. While writing code to multiply subtotal by a tax rate is trivial, maintaining real-time tax law compliance across changing municipal boundaries is impossible for a single engineering team. Custom implementations leave your business exposed to severe tax audit penalties and personal liability.
