Woo Checkout
WooCheckout Overview
Woo Checkout is used to charge the clients through WooCommerce Checkout. This option is useful when there is no way to make transactions via PayPal or Stripe in your country.

You should first create your own special Calculator Product using the WooCommerce plugin to use WooCommerce Payments. So you can assign your Calculator Product to the specific calculator form to be redirected to the Cart or Checkout page. To do this navigate to Products and click Add New:
The product that we are creating should be Simple type and do not forget to put a price:
The price of the Calculator product will be changed to the price of the Total Summary of Calculator Form.
The setting of the product image is optional. You can hide the product from the catalog in order to not display it on the WooCommerce Shop page:

After creating the WooCommerce Product we can start configuring the Calculator. Open the Cost Calculator dashboard and edit the selected calculator:
Then, to sell your service/product configured by the calculator on your website you can enable Woo Checkout from the Settings of the calculator:
After enabling the Woo Checkout option, the list of your WooCommerce products will appear. We need to choose the Calculator product we have previously created.
After choosing your proper Calculator product from the list, you should also choose whether you would like to redirect the visitors directly to the Cart or Checkout page after filling out the Calculator form.
In the next option, you will need to select the total field to charge the customers.
By default, it is for a calculator with a single Formula element.
However, in case you have a calculator form with more than one total element, you need to summarize them using an additional Formula element.
To make more clear this field, let's see another example of the calculator. In this example, we have four total elements:
In this calculator, there are a total element for the loan amount, annual interest rate, total months, and the total summary which sums ups all three totals.
In the main total summary field, the loan amount, annual interest rate, and the total months are summed up. That is why we will use the last total element in our Woo Checkout:
In the next step, go to your Calculator form page, fill out your form, and then click the Add to cart button to see your Calculator form on the Cart page or Checkout Page.
The string “Add to cart” comes from the Cost Calculator Builder PRO plugin and can be translated using the Loco translate plugin.
Redirection to the Cart page after submitting:
As you can see, the price of the Calculator Product is changed to the price of the Total Summary of Calculator Form.
Redirection to the Checkout page after submitting:
Customers should fill out the Billing details form and click Place order. After that the page with WooCommerce order details opens:
Please make sure that the default WooCommerce pages (Cart, Checkout, etc.) are configured and set under WooCommerce Settings > Advanced tools
The orders appear on the WooCommerce orders section:
By opening the order, you can find details of all selected options from the calculator:
