Odoo POS Integration with Cardlink, epay, NBG, Nexi & More | Methodoos

One Odoo. Multiple Payment Providers. One Seamless Payment Experience.

Methodoos is proud to introduce its expanded Odoo ERP and Point of Sale payment integration solutions, enabling businesses in Greece to connect their Odoo environment with payment terminals from multiple leading providers.

Through our integration with Mellon's WebECR infrastructure, alongside our dedicated epay integration, businesses can streamline electronic payments directly from Odoo, eliminating manual amount entry and simplifying everyday transactions.

Our solutions support a wide range of payment providers, including Cardlink (Worldline), NBG PAY, Nexi, myPOS, COSMOTE payzy, PBT, JCC, Credia, Tora, and epay, subject to terminal compatibility and provider configuration.

One Odoo Integration, Multiple Payment Providers

Businesses often operate with payment terminals from different banks and payment service providers.

Rather than maintaining disconnected payment processes, Methodoos brings terminal communication directly into Odoo through two integration approaches.

Mellon WebECR Integration

Our Mellon-based integration enables Odoo to communicate with compatible payment terminals across multiple payment providers using the supported WebECR infrastructure.

This approach provides businesses with greater flexibility when selecting or managing their payment terminals, without requiring a completely different Odoo workflow for each provider.

Dedicated epay Integration

Methodoos has also developed an integration connecting Odoo Point of Sale with epay payment terminals.

The integration allows transactions to be initiated directly from Odoo, automatically transfers payment amounts to the terminal, and returns the payment result to the Point of Sale interface.

Both solutions focus on creating a connected, efficient, and user-friendly payment experience.

Supported Payment Providers & POS Terminals

Our Mellon-based solution is designed for integration with a broad range of terminal models and payment providers.

Our solutions support a wide range of payment providers, including Cardlink (Worldline), NBG PAY, Nexi, myPOS, COSMOTE payzy, PBT, JCC, Credia, Tora, and epay, subject to terminal compatibility and provider configuration.

For the indicative compatibility list of supported terminal models, see Supported Payment Providers & POS Terminals. Final compatibility depends on the provider, terminal software version, enabled interconnection protocol, and merchant configuration.

How the Integration Works

With Methodoos payment integrations, the entire payment process is initiated and managed through Odoo.

Odoo ERP / Point of Sale → Payment Integration → POS Terminal → Customer Payment → Transaction Response → Odoo

  1. Payment Initiation: The cashier or ERP user selects the configured payment method in Odoo.
  2. Automatic Amount Transfer: The transaction amount is sent to the payment terminal.
  3. Customer Payment: The customer completes the card transaction using the connected terminal or compatible SoftPOS application.
  4. Transaction Confirmation: The payment result is communicated back to Odoo.
  5. Automatic Update: Odoo receives the transaction status, allowing the user to continue the corresponding sales or payment workflow.

This eliminates the need to manually enter amounts on the terminal and reduces unnecessary interaction between separate systems.

Supporting the Greek Payment Ecosystem

Electronic payment integration is an essential part of business operations in Greece, particularly following the introduction of mandatory interconnection requirements between payment terminals and ERP or cash register systems.

Methodoos develops its solutions with the Greek electronic payments ecosystem in mind, supporting relevant AADE ERP-to-POS interconnection requirements through applicable communication protocols.

The use of WebECR and provider-specific integrations enables businesses to establish connected payment workflows while accommodating different terminal infrastructures.

Specific compliance requirements and terminal compatibility are evaluated during implementation.

Flexible Payment Solutions for Odoo

Every business has different requirements.

Some organizations use a single payment provider, while others operate multiple stores, terminals, and payment service providers.

With Methodoos integrations, businesses can choose the payment connectivity solution that best fits their existing infrastructure.

Our goal is to make electronic payments a natural extension of Odoo rather than a separate operational process.
