PaySec + Odoo: Open-Source ERP Meets Zero-Fee Payment Processing
How businesses running Odoo are integrating PaySec's Network Offset Pricing to eliminate credit card processing fees across sales, invoicing, and e-commerce.
Odoo's modular, open-source ERP gives businesses the flexibility to build exactly the system they need — from CRM and accounting to inventory, manufacturing, and e-commerce. With over 12 million users worldwide and a thriving ecosystem of community modules, Odoo has become the go-to platform for businesses that want enterprise-grade functionality without enterprise-grade licensing costs. But when it comes to payment processing, even the most customizable platform can't eliminate interchange fees. That's where PaySec comes in.
PaySec's Odoo integration brings Network Offset Pricing to every payment touchpoint in your Odoo ecosystem — invoicing, POS, and e-commerce — so your effective processing cost approaches zero.
How Network Offset Pricing Works with Odoo
Network Offset Pricing (NOP) displays two transparent prices to your customers whenever they make a payment. Whether paying an Odoo invoice online, checking out on your Odoo e-commerce store, or tapping a card at your POS, the customer sees both a cash/ACH price and a card price. The card price includes a small offset that covers the cost of card processing.
For example, on a $2,000 B2B invoice:
- ACH/wire payment: $2,000.00
- Credit card payment: $2,080.00
The customer chooses their preferred method. Either way, your business receives the full $2,000. This approach is legal in all 50 states, fully compliant with Visa and Mastercard rules, and PaySec requires no contracts or minimum volumes. Approval typically takes 3-5 business days.

Who Benefits Most?
While any Odoo user processing card payments will see savings, certain profiles benefit most from the PaySec integration:
- B2B manufacturers and distributors processing high-value invoices where a single card payment can carry $50-$500+ in processing fees
- E-commerce operators on Odoo Website where card payments dominate and margins are tight
- Retail businesses using Odoo POS with consistent daily card transaction volumes
- Subscription-based businesses running recurring billing through Odoo Subscriptions where fees compound across every billing cycle
- Multi-company organizations managing several entities in one Odoo instance, each generating card payment volume
If your Odoo instance processes more than $30,000/month in card payments, the annual savings with PaySec will be immediate and measurable.
