our call
Start with LOVAT — highest vibe code, weakest moat.
LOVAT
Rebuilding the order aggregation dashboard and VAT threshold alerts takes less than a week with AI agents. However, LOVAT's core value is filing official returns directly with government tax portals across dozens of countries, which requires legal tax representation and specialized authorization. Building a dashboard is trivial; replacing the regulatory gateway is not.

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.
you can rebuild
- Basic percentage-based sales tax calculation API
- Exemption certificate file storage dashboard
- Simple order tax breakdown reporting for admin UI
- Static ZIP code to tax rate lookup table
- CSV transaction exporter for manual CPA review
what you lose
