About Odoo

Odoo is a full suite of business applications that includes a dedicated billing and accounting module. It handles invoicing, payment reconciliation, recurring subscriptions, and automated payment reminders. The billing system connects directly to inventory, sales, and project management modules, so invoices reflect real-time data without manual entry. Odoo can generate quotes, convert them to invoices, and handle multi-currency transactions.

Odoo runs on Linux, Windows, and as a cloud service. It integrates with payment gateways like PayPal, Stripe, and Adyen, and supports SEPA direct debits. The billing module includes tax reporting for multiple jurisdictions. The company behind it, Odoo S.A., releases the Community Edition under the LGPL license, while the Enterprise version adds advanced reporting and cloud hosting options.
