Oxygen MyData for WooCommerce


The WooCommerce Oxygen Suite extension allows you to automatically create your customers in WooCommerce as Clients in Oxygen Suite, and to create invoices (or draft invoices) for orders. View or download all invoices as PDFs and manage your order status easily.

By having all your data entered into Oxygen Suite automatically upon order, you save hours of manual entry every day, your customers will have immediate access to download PDF invoices, and you can even send invoices automatically.

An account with https://www.pelatologio.gr/ is required.
