Ecommerce vs Sales Tax Software

Most ecommerce businesses think they need sales tax software, but the real question is whether they actually need it yet. The problem is not automation, it is not knowing where you owe tax. Without exposure clarity, software only increases cost and complexity.

The Real Decision

1. Exposure

  • Where you owe tax
  • When thresholds are crossed
  • Which states require filing

2. Automation

  • Tax calculation
  • Reporting
  • Filing

Most ecommerce businesses jump to automation. Without solving exposure. That leads to unnecessary cost.
