How much does Sphere cost? The Starter plan is $100/month. Higher tiers aren't published; you'll need a quote for those.

Typical Sphere pricing

Headline prices like “starts at $X” rarely match what a real ecommerce brand pays. Here's what Sphere costs for two typical profiles. Both assume Shopify, monthly filing cadence, annual billing, and a typical $120 AOV. Plug in your own numbers in the calculator.

SMB

50K orders · 120 filings · 10 states · 5 SST · Shopify

From $12,000/ year

Recommended plan: Starter

Subscription
$12,000
Filings
$0

What this estimate assumes

  • At 10 regions you are past Sphere's published Starter tier, which covers fewer than 10 regions. Sphere routes 10+ regions to a quote-only Growth tier with no published price, so this figure is the Starter rate extended as a floor, not a quote.
  • No per-transaction fees below 50,000 transactions/month across active regions.
  • State-level registration fees may pass through (e.g., states that charge a permit fee).
  • Sphere is not an SST CSP.

Mid-Market

250K orders · 200 filings · 20 states · 10 SST · Shopify

From $24,000/ year

Recommended plan: Starter

Subscription
$24,000
Filings
$0

Pricing transparency

Partial

Some plans are public, others are quote-only. You can budget the bottom tier; everything else takes a call.

Downgraded from transparent 2026-08-18. The headline $100/region/month rate is still published, along with the 50,000-transaction threshold, but Sphere now caps that Starter tier at under 10 regions and routes anything larger to a quote-only Growth tier. The overage rate above 50,000 transactions has never been published, and no annual pricing is published at all. Sphere is still the most transparent vendor in the set at the low end; it just no longer publishes a price for every customer it serves.
