our call
Start with Storecove — highest vibe code, weakest moat.
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
- Real-time updated rate tables across 10,000+ US jurisdictions and global VAT/GST rules
- Direct automated tax return generation and remittance filing to state and federal agencies
- Government-mandated Continuous Transaction Controls (CTC) and e-invoicing framework compliance
- Address geocoding down to latitude/longitude for composite tax district boundaries
- Audit liability protection and direct enterprise compliance guarantees
real moats
- Regulatory compliance integrations with tax authorities worldwide
- Proprietary geospatial tax boundary maps updated dynamically as laws change
- Financial liability coverage and legal indemnification for calculation errors

Storecove
Storecove provides regulatory compliance, PKI certificate signing, and certified access to closed networks like Peppol, Italy's SDI, Poland's KSeF, and Saudi Arabia's ZATCA. Generating an XML file from an order payload is easy, but passing government security audits and staying compliant across 40+ dynamic national legal mandates is not software you can build and forget. Attempting to self-host this stack introduces legal liabilities and immediate failure on international B2G/B2B mandates.

- JSON order to standard UBL 2.1 XML format transformation engine
- Basic PDF invoice parsing and rendering
- Storefront webhook listeners for invoice triggers
- Local dashboard for displaying sent invoice logs and delivery status

what you lose
- Certified Peppol Access Point transport via secure AS4 protocol
- Direct clearance integrations with mandatory state tax portals (SDI, KSeF, ZATCA, etc.)
- Legal compliance updates when international e-invoicing laws change
- Qualified electronic signatures (QES) and PKI certificate management
- Legally binding audit trails for tax authority inspection
