Start with Complyt — highest vibe code, weakest moat.

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.

- 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

open source escape hatches
