Dutch and Belgian shoppers overwhelmingly expect to pay with iDEAL and Bancontact — and if your Odoo store only offers cards, you leak conversions at the exact moment of purchase. ECOSIRE builds you a first-class, native Odoo payment provider that adds an iDEAL issuing-bank selector and a Bancontact bank-redirect / QR flow directly into your eCommerce and Sales checkout, wired to the PSP you already use.

This is a build-to-order engagement, not a generic apps.odoo.com download. We scaffold a proper Odoo module — a clean __manifest__.py declaring dependencies on payment, website_sale and account; a payment.provider extension (models.Model inheriting the core provider) plus a payment.method for iDEAL and Bancontact; and a payment.transaction subclass that handles the redirect handshake and the asynchronous status callback. Amounts, currency and the customer's chosen issuing bank flow through the standard Odoo payment abstraction, so nothing about your existing quotations, sale orders or invoices changes.

Because iDEAL and Bancontact are bank-redirect methods, correctness lives in the webhook. We implement a hardened controller that receives your PSP's asynchronous notification, verifies the signature/HMAC, is idempotent against duplicate deliveries, and reconciles the transaction back to the sale order and invoice — flipping the order to paid only on a confirmed settlement, never on the browser redirect alone. That closes the classic gap where a shopper closes the tab mid-redirect and the order is left in limbo.

The provider is PSP-agnostic by design. Whether you settle through Mollie, Stripe, Adyen, Buckaroo, MultiSafepay or another Benelux acquirer, we map your credentials, endpoints and method identifiers into a single Odoo provider configuration with clean test/live toggles — so you are never locked to one gateway. EUR localization, correct Dutch/Flemish/French labelling, VAT-consistent amounts and Benelux-appropriate checkout copy are handled as part of the build.

Everything ships the Odoo way: access controlled via ir.model.access.csv and record rules so only Billing/Accounting roles touch provider secrets; configuration exposed through standard Settings views (XML/OWL) rather than code edits; QWeb-rendered payment status on the order and portal; automated actions to chase or auto-cancel stale pending transactions; and optional XML-RPC/JSON-RPC hooks so back-office or headless systems can read transaction state. It runs on Odoo Community or Enterprise and we deliver against your exact version — 17, 18 or 19.

ECOSIRE builds it, installs it on your server or Odoo.sh, tests real bank-redirect and refund flows in sandbox and production, hands over documentation and training, and stands behind it with a support window. Typical delivery is 2–4 weeks depending on your PSP and edge cases.
