Overview

What does this module do?

This module extends the Odoo 18 Stripe payment provider to automatically calculate and collect a configurable processing fee when a customer pays by credit or debit card. The fee is computed in real time on the payment portal, displayed as a dedicated line item so customers always know exactly what they will be charged before confirming, and then reconciled back into the sale order as a separate order line once payment is confirmed via Stripe webhook. Bank transfers and ACH payments are fee-free.

Example Payment Summary (Card)
Order Subtotal$100.00
Stripe Processing Fee 2.9% + $0.30$3.20
Total Charged$103.20
✅
Transparent by design Customers see the exact fee before confirming payment — no hidden charges, no surprises after checkout.

Key Features

Everything you need to collect and reconcile Stripe processing fees transparently.

⚡
Real-time Fee Calculation
Fee is computed and shown instantly on the payment portal the moment the customer selects a card payment method.
⚙️
Configurable Rate
Set your own percentage and fixed amount per payment provider directly in Odoo settings — no code change required.
🧾
Separate Line Item
The fee appears as a dedicated order line on the sale order and linked invoice, keeping accounting clean and auditable.
💳
Card-only Trigger
Fee panel shown only when a card method is selected. Bank transfers and ACH payments remain fee-free automatically.
🛡️
Idempotency Safe
Duplicate fee lines are prevented even if Odoo's payment cron retries a transaction multiple times.
🔗
Webhook Integration
Fee order line is auto-created on payment confirmation via the Stripe webhook using a safe sudo pattern.
📋
Portal Transparency
Full fee breakdown (subtotal, fee, total) shown to customers before they confirm — no surprises.
💾
Saved Card Support
Fee breakdown also appears correctly when customers pay with a saved card on file in the Odoo portal.

Step-by-Step Setup Guide

From installation through live fee collection.

  1. Install the Module

    Go to Apps → Search “Stripe Processing Fee Extension” → Install.

    💡
    Prerequisites Requires payment_stripe, sale, and website_sale. The Stripe provider must be configured and active first.

  2. Verify Auto-created Fee Product

    After install, a Stripe Processing Fee product is auto-created under Sales → Products. This product is used as the fee order line — do not delete it.

  1. Open Stripe Provider Settings

    Go to Accounting → Configuration → Payment Providers → Stripe.

  2. Set the Fee Rate

    FieldDescriptionDefault
    Fee PercentageVariable part as % of order total2.9%
    Fixed FeeFlat amount added per card transaction$0.30
    Fee ProductOdoo product for the fee order lineAuto-created

  1. Verify Stripe Webhook is Active

    The fee order line is created when Stripe confirms payment via webhook. Confirm the webhook URL is registered in your Stripe Dashboard under Developers → Webhooks.

    ⚠️
    Important Without an active webhook, the fee line will not be added to the sale order after payment. Ensure payment_intent.succeeded event is enabled.

  2. Test with Stripe Test Mode

    Use Stripe's test card 4242 4242 4242 4242 to simulate a card payment and verify the fee line appears on the sale order.

  1. Customer Checkout Experience

    When a customer selects a card method, the fee breakdown block appears automatically showing Order Subtotal, Processing Fee, and Total Charged.

  2. Review the Fee on the Sale Order

    After successful payment, open the sale order in Sales → Orders. The fee appears as a dedicated order line and is included in the invoice automatically.
