From $7,490

This is Avalara's published list price, shown as a floor rather than an exact figure. Avalara publishes the per-state rate but not the transaction limits, included return counts, or overage rates behind it, and its own pricing-page FAQ still says cost factors include transaction volume and integration footprint. +7 more
