Thanks to YITH Request a Quote for WooCommerce you can offer users the chance to ask for a quote for one or more products in your shop. Once the request is received, the admin can reply to the offer and send it back to the customer.
Using it in combination with the YITH WooCommerce Deposits / Down Payments plugin, the admin can enable a percentage deposit that the customer will have to pay when accepting the quote. The payment of the balance order will be managed by YITH Deposits / Down Payments.
The customer will add product(s) to the quote as usual. When the quote is created the admin can choose if the customer should pay a deposit.
If the admins decide to add a deposit to the quote, they can set this option from the backend by editing the quote (WooCommerce > Orders).
The admin can enable the option and set a percentage of the deposit that will be calculated from the quote total. The customer, after accepting the quote, will need to pay the deposit.
The payment of the balance order will be then managed by YITH Deposits / Down Payments, that is the customer will be able to complete the payment from the My Account page as usual.
