The WooCommerce Invoice Gateway is a free plugin designed for WordPress, enhancing the WooCommerce experience by providing an invoice payment option. This gateway is particularly beneficial for B2B transactions where immediate digital payments might not be feasible. Users can select from various WooCommerce order statuses, such as On Hold, Pending Payment, Processing, or Completed, ensuring that order management remains streamlined. The plugin also allows for customization, enabling the restriction of the gateway to specific WordPress user roles, which adds an extra layer of control for site administrators.

It is important to note that while the WooCommerce Invoice Gateway facilitates order processing, it does not generate customer invoices. Users will still need to rely on external accounting software such as Quickbooks for invoicing. The plugin supports the WooCommerce block-based checkout and HPOS, making it a versatile option for those looking to integrate invoice payments into their online store.
