our call
Start with TaxJar — highest vibe code, weakest moat.
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.
