No. This is a build-to-order app that ECOSIRE designs, builds and installs for your store. After purchase we scope your carriers, zones and order volume, then provision a dedicated app and complete the OAuth install on your Shopify org. You are buying bespoke software plus the install, not a self-serve download.

We start with a short scoping call to confirm your carrier accounts, shipping zones and warehouse workflow. A standard build typically lands within a few weeks; complex cross-border customs flows or many carrier integrations extend that. We give you a firm timeline in writing before development begins — no work starts until scope and lead time are agreed.

Every build includes a post-launch support window for fixes and tuning, plus handover documentation and a team walkthrough. Beyond that, ECOSIRE offers continued support and maintenance — carrier API changes, new shipping rules, added carriers and Shopify API-version upgrades — under an ongoing arrangement scoped to your needs. You are never left to maintain bespoke code alone.

Yes. Your own carrier account credentials are stored in a credential vault and used for rate shopping, so quotes reflect your negotiated rates rather than retail pricing. The rules engine then picks the cheapest or fastest compliant service per your configuration across the 170+ supported carriers.

Yes — that is a core focus. The app generates commercial invoices and CN22/CN23 customs declarations, and stores HS codes and country-of-origin on product metafields so the data is populated automatically at fulfillment. Carrier selection is zone-aware so cross-border parcels route through services that accept the destination and declared contents.
