Who this is for

  • Online stores, course sellers, and digital product businesses
  • Small SaaS companies selling to customers in multiple states
  • Founders who are not sure when sales tax software matters
  • Businesses comparing Quaderno, Stripe Tax, TaxJar, or accountant managed workflows

Core steps

  • Identify where the business has physical presence, employees, inventory, or offices.
  • Track sales by state so you can see whether economic nexus thresholds may be approaching.
  • Check whether the products or services you sell are taxable in each state.
  • Review marketplace facilitator rules if you sell through a platform.
  • Register before collecting sales tax in a state, and keep registration and filing dates organized.
  • Use software or professional help when manual tracking becomes risky.

Price and cost notes

Costs may include state registrations, filing support, accountant review, and sales tax software. Quaderno, TaxJar, Stripe Tax, and other providers price their tools differently, so use official pricing pages and match cost to your transaction volume and filing needs.

Pros

  • Early tracking prevents surprise nexus problems
  • Software can help monitor thresholds and collect location evidence
  • Clear registration timing avoids collecting tax before registration
  • Better records help if a state asks questions later

Cons

  • Rules vary by state and product type
  • Economic nexus thresholds can change
  • Software does not replace professional tax judgment
  • Very early businesses can overbuy tools before they have real exposure

Next step

Export sales by state for the last twelve months and mark any state where volume is growing quickly.
