our call

Start with Anrok — highest vibe code, weakest moat.

Anrok

Building a basic UI to add state tax rates is easy, but maintaining compliance across 11,000+ US tax jurisdictions and handling automated state tax filings cannot be prompted into existence. You pay Anrok for regulatory accuracy, updated rate tables, and managed tax returns.

you can rebuild

  • Basic state revenue aggregation dashboard
  • Customer billing address state tagging
  • Simple nexus alert threshold notifications
  • Manual CSV export of transaction totals by state
  • B2B exemption status toggle on customer profiles

what you lose

  • Automated tax return preparation and remittance to state revenue departments
  • Real-time rooftop-level geocoding for 11,000+ US tax jurisdictions
  • Global VAT/GST calculation and compliance rules for SaaS
  • Audit support and legal liability indemnification
  • Continuous tracking of state-by-state economic nexus rule changes

real moats

  • Filing infrastructure and legal integrations with government state revenue departments
  • Dedicated team of tax attorneys tracking rate and taxability changes globally
  • Proprietary GIS boundary database mapping exact street addresses to tax districts

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

  • Regulatory compliance integrations with tax authorities worldwide
  • Proprietary geospatial tax boundary maps updated dynamically as laws change
