Who this is for

U.S. and international Shopify stores selling into multiple U.S. states.

Who this is not for

Marketplace-only sellers, or stores selling in a single state with no nexus anywhere else.

What we handle

Every piece of Shopify sales tax.

One team for the whole job, from the first registration to the last notice. Prices are published, so you know before you talk to us.

Registrations

State registrations

We set up your sales tax account in every state where your store has nexus, in the right order, as part of onboarding.

From $49 per state

Filings

Returns filed & remitted

Monthly, quarterly, and annual returns prepared from your Shopify data and filed on time, every period.

$29 per filing

Nexus monitoring

Economic nexus monitoring

Tracked in your Shopify Tax reports through collaborator access, so we register you before you owe.

Included in the base fee

Reconciliations

Sales tax reconciliations

Tax collected in Shopify matched to tax remitted, jurisdiction by jurisdiction, so the numbers always tie out.

Included in the base fee

Transcripts

State transcript monitoring

We pull your state account transcripts to confirm every payment posted and every balance is clear.

Included in the base fee

Notices & audits

Notices & audit support

State letters triaged and answered for you, with representation if an audit ever lands.

From $29 per notice

Nexus monitoring

We watch every state, so you don’t find out at filing time.

Thresholds differ by state, some count orders as well as dollars, and each uses its own window. We track all of it in your Shopify Tax reports and register you before you owe, not a year after.

  • Every state’s dollar and order thresholds, reviewed each January
  • This year, last year, or trailing 12 months, per state
  • Inventory and 3PL states flagged as physical presence

How it works

Three steps, then we run it.

It starts with a conversation, not a checkout. You only pay once you’ve seen the plan and said yes.
