In a nutshell, we’ll use the same WooCommerce cart/checkout flow, rename a few strings and buttons, enable an offline payment gateway (so there is no actual payment), let the admin revise the order and send back the final invoice, and finally get the customer to pay for their order.
Enjoy!
You’re looking at the WooCommerce Checkout page, with the only difference being the “PLACE ORDER” button, the page title and the fact the only possible payment method is “cheque” (renamed to “Pay Later”). The customer creates the order, the admin revises it, and sends back the customer to the “Order Pay” page so that they can finally pay for the final invoice.
Setup Info
In order for the quote system to work you must:
Rename the Checkout page to “Quote”, “Your Quote” etc. and possibly, remove the Cart page all together.
Enable “cheque” payment method, hoping you are not already using it for accepting actual checks… Rename it to “Get a Quote”, “Pay Later” or similar. This will be the only visible payment method on the Checkout page.
Take a note of all your online payment gateway IDs e.g. “paypal”, “stripe”, etc., as we need to show these only when the customer receives the invoice back from the admin, on the “Order Pay” page. Besides, these same gateways must be hidden on the default checkout/quote page.
Know that the admin, once they receive the unpaid order, can edit the order from the dashboard (add shipping, revise product prices, add fees, etc.) and set it to “Pending Payment”. This will generate an “Order Pay” URL that can be sent to the customer via the relevant order action i.e. “Send customer invoice”.
