how add orders manually or via API ?

Hi @sia0368,

Thank you for reaching out.

While your thought process is well mapped out, you may find it useful to consider hiring a professional developer or freelancer who specializes in WooCommerce. They can provide you with expert guidance to ensure your project achieves its required functionality.

While WooCommerce is highly robust, achieving this desired level of detail may involve the use of additional plugins or some custom code for a tailored solution.

The WooCommerce community is filled with talented open-source developers, and many of them are active on the channels listed below:

• WooCommerce Developer Resources Portal
• WooCommerce Advanced Facebook group
• WooCommerce Developer Slack Channel
• Hire a?WooCommerce Expert

Hope this helps!
