Retail and hospitality teams running Odoo POS routinely end up with two disconnected systems at the counter: the POS session on one screen and a standalone card terminal that the cashier keys the amount into by hand. That manual re-keying is where the money leaks — mistyped amounts, tenders marked "paid" in Odoo that never actually cleared on the terminal, tips and partial payments that don't map back to the order, and end-of-day cash-ups where the POS account.bank.statement never agrees with the acquirer's settlement report. Odoo Community POS ships generic payment methods and, on Enterprise, integrations for a specific set of first-party terminals, but out of the box it has no driver for an arbitrary acquirer's terminal, no automatic amount push, and no way to write the acquirer's transaction reference back onto the POS order line.

ECOSIRE builds a made-to-order payment-terminal connector for Odoo POS that closes that loop. Technically, we register a new payment method backed by a custom pos.payment.method variant and an OWL frontend payment interface that the POS screen calls when the cashier selects the terminal tender. The interface pushes the exact order total (and, where the terminal supports it, tip and cashback prompts) to the reader over its documented local network, cloud, or SDK transport, then waits on the transaction result. On approval it stamps the acquirer reference, card scheme, and authorization code onto the pos.payment record via new fields declared with fields.Char/fields.Monetary and persisted through the ORM, so every settled tender carries a machine-readable trace back to the terminal. Declined, cancelled, and timed-out transactions are surfaced back into the POS UI as a clean retry rather than a silent mismatch. Server-side Python (models.Model, @api.depends computes for reconciliation status) handles the accounting hand-off, and access is locked down through ir.model.access.csv plus record rules so terminal configuration and transaction logs respect POS-manager versus cashier roles.

Because it is built on the standard POS and accounting models, the integration reconciles the way Odoo expects: terminal captures flow into the POS session's payment lines, close into the session's account.move/statement, and can be matched against the acquirer settlement using the stored reference — no spreadsheet gymnastics. We wire optional automated actions for refund/void handling and expose the transaction log through Odoo's own views and QWeb so finance can pull a reconciliation report without touching the terminal portal. Where your workflow needs it, the connector can be driven headlessly through Odoo's XML-RPC/JSON-RPC API for kiosk or self-checkout scenarios. We target Odoo 17.0, 18.0, and 19.0, and we account for Community-versus-Enterprise differences in the POS payment framework so the build matches the edition you actually run.

Delivery is build-to-order, not an instant download. After a short scoping call we confirm your Odoo version and edition, your exact terminal model and its supported transport (local IP, cloud, or vendor SDK), your acquirer's settlement/refund flow, and any tip/multi-currency/multi-company requirements. We then build the module, prove it on a staging copy of your database through UAT, and deploy to production with a rollback plan. Typical delivery is 2–4 weeks from confirmed scope. Pricing starts from $249 (indicative, single-company base scope); additional terminal models, multi-company or multi-currency reconciliation, self-checkout/kiosk transports, and deeper acquirer refund-and-settlement automation increase the quoted scope. You receive a fixed quote after the scoping call — never a surprise.
