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.
Rooftop-accurate rate calculation resolving state, county, city and special-district tax to the exact delivery address at checkout
Economic-nexus tracking that aggregates sales revenue and transaction counts per state against each state's current threshold
Threshold proximity alerts (for example 80% and 100%) delivered before you incur a registration obligation
Product taxability mapping using Streamlined Sales Tax (SST) categories, stored per SKU in Shopify product metafields
Marketplace-facilitator sales detection and exclusion so Amazon, Walmart, eBay and Etsy orders aren't double-remitted
Shopify Admin API webhook ingestion (orders/create, orders/updated, refunds/create) for real-time, refund-adjusted tax totals
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.
Sells nationwide from one or two warehouses and has crossed economic-nexus thresholds in several states without realizing it. Needs proactive alerts and accurate per-jurisdiction collection before an audit finds the gap.
Owns sales-tax compliance across Shopify and marketplaces. Needs marketplace-facilitator sales excluded, audit-ready reconciliation reports, and a reliable filing calendar instead of spreadsheets.
Growing fast across multiple locations and SKUs with mixed taxability. Needs rooftop-accurate rates, metafield-driven product tax categories, and automated filing that keeps pace as nexus expands.

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.
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.
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.
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.
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.
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.
