It is not an instant download — this is a build-to-order extension that ECOSIRE builds, installs and configures on your store. Typical delivery is roughly one working week depending on your edition, QBO region, chart-of-accounts complexity and order volume. We start on a staging copy, map your accounts and tax codes, run test syncs end to end, then cut over to production with you.

Every build includes a post-launch support window and a bug-fix warranty. Because the QuickBooks Online REST API v3 and OAuth credentials evolve, we offer an ongoing maintenance option that covers QBO API-version updates, Magento upgrade compatibility, and priority fixes. You own the source either way, so you are never locked to us.

Yes. The module is built against standard Magento 2 extension points — di.xml plugins, observers, service contracts, admin ACL and cron — so it runs on Magento Open Source and Adobe Commerce (cloud or on-prem). We confirm your exact version and edition before building and test on a matching staging environment.

Each Magento entity is matched to its QBO counterpart and tracked with an idempotency key and a stored QBO ID, so re-running a sync or a webhook retry updates the existing record instead of creating a duplicate. Customers are deduplicated by email, and the admin sync log shows exactly which Magento record maps to which QBO document.

Failed or throttled requests are queued and retried automatically with exponential backoff, and the Magento cron-based batch mode re-attempts any record that did not post in real time. Nothing is silently dropped — every failure is visible in the admin sync dashboard with the error detail and a one-click manual re-push.

Yes — that mapping is a core part of the build. During setup we connect to your QBO company, read your real accounts, tax codes and items, and map Magento orders, shipping, discounts, taxes and payment methods to the correct QBO targets, configurable per store view for multi-store setups.
