The Problem

There are 13,000+ tax jurisdictions in the US, each with different rates and rules. Economic nexus laws mean sellers can owe sales tax in states where they've never set foot. Filing returns manually across 20+ states takes 40+ hours/month. Non-compliance penalties average $20K–$50K per state.

Why Now?

Economic nexus laws expanded after South Dakota v. Wayfair. States are actively auditing online sellers. Marketplace facilitator laws are creating new compliance requirements. E-commerce growth means more sellers crossing nexus thresholds.
