our call
Start with Complyt — highest vibe code, weakest moat.
Complyt
Building a script to count state sales volume against static nexus thresholds takes a few hours. However, maintaining updated rate databases across 12,000+ local tax jurisdictions, product taxability codes, and state-level legal liability makes DIY code a massive financial risk.
you can rebuild
- State sales volume and order count aggregation per state
- Economic nexus progress bars and threshold warning alerts
- Shopify REST/GraphQL webhook order sync and historical sync
- Basic email alerts when reaching state threshold milestones
- State registration status tracking and internal notes dashboard
what you lose
- Automated dynamic tax rate calculations across 12,000+ US jurisdictions
- Product category taxability matrices and exemption rule engine
- State tax audit indemnification and professional CPA oversight
- Direct electronic tax return filing to individual state tax portals
- Physical nexus tracking tied to remote employees and 3PL fulfillment locations
real moats
- Continuous maintenance of state and local tax rate boundary tables
- Legal indemnification for calculation errors during state tax audits
- Direct API integrations and filing workflows for state tax department portals

TaxCloud
TaxCloud handles dynamic calculations across 13,000+ US tax jurisdictions, tracks economic nexus thresholds, and remits tax returns directly to state tax authorities. Building the UI is simple, but maintaining GIS tax boundary datasets and holding state filing legal authorization cannot be replaced with custom code.
you can rebuild
- Basic tax rate calculation UI
- Economic nexus threshold monitoring alerts
- Exemption certificate document upload portal
- Order line item tax logging dashboard
- CSV sales tax report export for manual filing
what you lose
- Automated monthly/quarterly tax return filing to state revenue departments
- GIS address matching for 13,000+ US local tax jurisdictions
- Streamlined Sales Tax (SST) program subsidization and legal audit defense
- Real-time updates to changing state tax laws and product taxability rules
- Power of attorney execution for state-level remittance
