About this Product

USPS Shipping for Magento 2 is a build-to-order carrier extension that gives US merchants accurate USPS rates at checkout plus a full back-office label, SCAN-form and tracking workflow — without the per-shipment fees of a hosted shipping app.

This is not an instant Adobe Commerce Marketplace download. ECOSIRE builds the module to fit your store, installs it on your environment, and supports it after go-live. The extension ships as a proper module under app/code/Ecosire/UspsShipping, registering a custom online carrier model that implements Magento\Shipping\Model\Carrier\AbstractCarrierOnline and CarrierInterface. Rate requests are collected through the standard collectRates() flow so USPS quotes appear natively alongside your other methods in the cart and checkout, fully compatible with Open Source (CE) and Adobe Commerce (EE/Cloud).

We wire USPS authentication and endpoints into admin system configuration (system.xml + config.xml) under Stores → Configuration → Sales → Shipping Methods, with credentials stored encrypted. A Commercial/retail pricing toggle requests the correct USPS price tier per service. Label generation, SCAN-form creation and tracking-number write-back are implemented via service contracts and admin controllers gated by granular ACL resources (acl.xml), so only authorized roles can buy postage. Plugins/interceptors (di.xml) and observers extend order shipment creation cleanly without core edits, and a cron job can batch SCAN forms and refresh tracking statuses.

Everything is delivered with REST/GraphQL-friendly extension attributes where you need rates or tracking exposed to a headless or PWA frontend. You get the source, install on staging then production, and an honest delivery timeline up front.

What you get

Custom Magento 2 module Ecosire_UspsShipping delivered as source under app/code (or a Composer package on request)

Installation and configuration on your staging environment, then production cutover with rollback notes

Admin configuration walkthrough: USPS credentials, Commercial/retail toggle, enabled services and box mappings

Setup and Upgrade scripts (declarative schema where needed) plus di.xml, system.xml, config.xml, acl.xml and cron wiring

Short admin guide covering rate config, label printing, SCAN-form generation and tracking

Compatibility validation against your Magento line (Open Source or Adobe Commerce) and PHP version

Post-launch support window with bug fixes and a USPS API-change update path

Who this is for

US Magento merchant shipping domestic parcels

Sells physical goods to US customers and relies on USPS Priority, Ground Advantage and Flat-Rate boxes; needs accurate checkout rates and one-click labels instead of re-keying orders into Click-N-Ship.

Operations / fulfillment lead

Runs daily pick-pack-ship and wants batched SCAN forms, tracking write-back into Magento, and ACL controls so only warehouse roles can buy postage.

Store owner with negotiated Commercial rates

Qualifies for USPS Commercial pricing and needs the storefront to quote the discounted tier so margins are protected and checkout matches the actual postage paid.

Frequently Asked Questions about USPS Shipping for Magento 2

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. ECOSIRE builds the module to match your Magento line and USPS account, installs it on your staging then production environment, and supports it afterward. There is no instant Marketplace download or self-serve install link.

How long until it is live on my store?

Typical delivery is about 1 to 2 weeks from the time we have your USPS API credentials, environment access and a confirmed Magento/PHP version. Simpler single-store setups land faster; heavily customized or multi-website stores with extra box rules or headless frontends take a little longer. We confirm a firm timeline before starting.

What ongoing support and updates do I get?

Every build includes a post-launch support window for bug fixes. Because USPS periodically changes its rate API and pricing, we offer an update path to keep the integration working against API changes and to track Magento minor upgrades. We can also set up a longer support and maintenance retainer if you want guaranteed response times.

Does it work with both Open Source and Adobe Commerce (including Cloud)?

Yes. The carrier model uses standard Magento shipping service contracts and the collectRates() flow, so it runs on Magento Open Source (CE) and Adobe Commerce (EE and Cloud). We validate against your exact version and PHP release as part of delivery.

Will it support USPS Commercial pricing and Flat-Rate / Regional-Rate boxes?

Yes. A Commercial/retail toggle requests the correct USPS price tier so quotes reflect your negotiated rates. Flat-Rate and Regional-Rate boxes are mapped to the right USPS products with per-box weight and dimension settings so the cart quotes and the printed label agree.

Does it avoid core edits and survive upgrades?

Yes. All behavior is added through a dedicated module using di.xml plugins/interceptors, observers and service contracts — no app/code/Magento core files are modified. This keeps the extension upgrade-safe across Magento minor releases.
