Online sellers struggle to track economic nexus and file sales tax across many states without a clear obligations dashboard
Sellers and SaaS founders repeatedly hit the multi-state sales tax wall: every state has different nexus thresholds, registrations, and filing cadences, and most discover obligations only after crossing a threshold. The 'Amazon Sellers Brood as States Come Calling for Taxes' thread (160 pts) and a Mar-2025 Ask HN on handling VAT/sales tax as B2C SaaS (97 pts) show this is a recurring, unresolved operator pain. Avoid competing head-on with Avalara/TaxJar on full automation; the differentiated sub-problem is a lightweight obligations-tracking dashboard that warns sellers before they trip a nexus threshold and tells them exactly where to register.

Avalara, TaxJar, Stripe Tax handle calculation and filing but are heavy and priced for scale; small sellers want a cheaper early-warning nexus tracker. Differentiated angle: pre-threshold nexus monitoring and registration guidance for small multi-channel sellers.
