この製品について
US Sales Tax Automation & Nexus Tracker is a Shopify app ECOSIRE custom-builds, installs and maintains for your store — it is not a one-click App Store download. After purchase, our engineers build it against your catalog, ship-from locations and sales history, then install it as a private/custom Shopify app on your store.
What it does. The app registers Shopify Admin API webhooks (orders/create, orders/updated, refunds/create, app/uninstalled) and uses Shopify's GraphQL Admin API to read fulfillment locations, multi-location inventory and order line items. At checkout it returns rooftop-accurate rates resolved to the delivery address — state, county, city and special-district — applying the correct product taxability rules (Streamlined Sales Tax / SST categories) per SKU. Each SKU's tax category is stored in Shopify metafields so taxability travels with the product.
Who it's for. US-based and US-selling Shopify merchants who have crossed — or are about to cross — economic-nexus thresholds in multiple states and need to stop guessing. The built-in Nexus Tracker rolls up your sales and transaction counts per state, compares them to each state's threshold, and alerts you before you trip a registration obligation. It also correctly excludes marketplace-facilitator sales (Amazon, Walmart, eBay, Etsy) so you don't over-count or double-remit.
How it's delivered. OAuth-scoped, installed by ECOSIRE, configured to your nexus footprint, and handed over with a filing calendar and audit-ready reports. Ongoing support, state-rate updates and threshold-rule changes are covered by ECOSIRE so the app stays correct as state laws shift.

US Sales Tax Automation & Nexus Tracker に関するよくある質問
Is this a free app I install instantly from the Shopify App Store?
No. This is a build-to-order app that ECOSIRE custom-builds for your store and installs as a private/custom Shopify app via OAuth. There is no public App Store listing or instant download — it's configured to your specific catalog, ship-from locations and nexus footprint.
How long does delivery take after I purchase?
Typical build, configuration and installation takes about 10 to 15 business days, depending on the size of your catalog, the number of states in your nexus footprint, and how much taxability mapping your SKUs need. We confirm a firm timeline during onboarding before work starts.
What ongoing support and updates are included?
ECOSIRE provides ongoing support that covers bug fixes, Shopify Admin API/webhook compatibility, state rate updates, and economic-nexus threshold-rule changes as state laws evolve. Because US tax rules change frequently, this app is maintained — not a one-time delivery you're left to keep current yourself.
Does it handle marketplace sales like Amazon and Walmart?
Yes. The app detects marketplace-facilitator orders and excludes them from your nexus aggregation and remittance, since those platforms collect and remit on your behalf. This prevents double-counting toward thresholds and double-remitting tax.
How does it know which products are taxable in each state?
Each SKU is assigned a Streamlined Sales Tax (SST) product-tax category, stored in Shopify product metafields during the build. The app applies the correct state-specific taxability rule for that category at checkout, so items like apparel, groceries or digital goods are taxed correctly where rules differ by state.
Can it actually file returns, or just calculate tax?
It does both. Beyond rooftop-accurate calculation, ECOSIRE configures automated state registration assistance and scheduled return filing for the states where you have nexus, plus a per-state filing calendar and audit-ready reconciliation reports so each return ties back to collected tax.
