USPS Shipping Connector for Odoo

This is a build-to-order module, not an instant apps.odoo.com download. After purchase, ECOSIRE scopes your USPS account, services and warehouse workflow, then builds, installs and tests the connector on your Odoo instance. Typical delivery is 2-4 weeks depending on the number of USPS services, international requirements and any address-validation or checkout customizations. You get a firm timeline at the end of onboarding.

Every build includes a post-go-live support window for bug fixes and adjustments within the delivered scope — the exact duration is confirmed in your quote. Because USPS periodically changes its rating/label APIs and service names, we also offer ongoing maintenance to keep the connector current. You own the source code, so you can extend it in-house or bring us back for enhancements at any time.

We build for Odoo 17.0, 18.0 and 19.0, on both Community and Enterprise. The connector extends standard delivery.carrier and stock.picking models, so it works with core Inventory, Sales and eCommerce. Tell us your version and edition during onboarding and we target it precisely; when you upgrade Odoo later, we provide a documented migration path.

The module registers a USPS delivery method that calls the USPS Domestic/International rating API using package weight, dimensions and destination. Rates appear as a selectable shipping option on the sale order and on the Odoo eCommerce checkout, so customers and sales reps see accurate USPS pricing before confirming. API errors (bad address, over-weight service) are surfaced inline rather than failing silently.

Yes. We support USPS international services with label generation and customs declaration data (CN22/CN23-style fields) drawn from product weight, value and origin/HS fields already in Odoo. The exact international services and customs fields are confirmed during scoping so the labels match what your carrier and destination countries require.

Yes — you provide your USPS Business/API account (for example a USPS Web Tools or current USPS API account with rating and label permissions). We wire those credentials securely onto your company record in Odoo (never hardcoded in the module) and map your enabled services. If you don't yet have API access, we'll guide you through requesting it as part of onboarding.

No. The connector is a self-contained module that extends standard shipping models and adds its own views, security rules and scheduled action. We install and test on a staging database first, verify rating, label purchase, SCAN form and tracking sync, then promote to production. Access to credentials and label actions is restricted via ir.model.access.csv and record rules to authorized roles only.
