Get Started

Start with the AtomicTax workflow.

Open the AtomicTax app to connect a source system and automate your sales tax workflow, or book a demo first if you need to review your setup. File uploads are still supported when a connected path is not ready yet.

Best ways to start

  • Connect a storefront, marketplace, billing tool, or API source first
  • Use CSV, Excel, or PDF uploads only if that is your current fallback workflow
  • Confirm the states, registrations, and filing periods that matter
  • Review whether your current setup needs nexus or registration work first

What AtomicTax organizes

  • Connected reporting inputs
  • Nexus monitoring and state visibility
  • Registration workflow
  • Recurring filing calendar and approval flow
