1. Do you have a screenshot please?

2. Try this CSS:

#wpinv_country_box,  #wpinv_state_box, #wpinv-wpinv_phone-wrap, #wpinv-wpinv_zip-wrap {display:none}
label[for="wpinv_phone"], label[for="wpinv_zip"] {display:none}

3. I cannot replicate that on my test site. What browser are you using?
Can we get your URL and WP admin details in a private reply so we can check?

Thanks

Easiest are PayPal [Standard] and Stripe.

Refund policy can be found here: https://wpinvoicing.com/refund-policy/

GD packages can only be added to the cart by submitting a listing.
I had missed that part of the question first.

Go to Invoicing in the backend, and edit the invoice.
Change the Invoice Status to “Refunded”.
Then use the refund process of the gateway that was used.

If you’d like to give a credit instead, then you can create a discount code for the same amount, that can be used only once.

Thanks

You may be able to create a basic shopping experience using this addon: https://wpinvoicing.com/downloads/contact-form-7/

You will have to create a different form for each option that people can order.

Thanks

Please check now. I un-installed Invoicing and re-installed it.
It looks like the folder name of the plugin was changed, but I am not sure.
Let us know. Thanks

Why do you use Invoicing and WooCommerce at the same time.
Can you describe for which customer actions you use Invoicing and for which ones you use WooCommerce?

Also post your URL and WP admin details in a private reply so we can have a look at your settings. Thanks
