Woocommerce Orders

Here is the issue. We raise grass fed livestock on our farm. We require a customer online to order livestock shares prior to the animal being butchered. Below is an example of a Beef Share. Purchase Options for a Beef Share Half Side – est 300 lbs. $5.25 lb. HW* Down Payment $400 Whole – est 600 lbs. $4.95 lb. HW* Down Payment $600 The problem is we want to show the price online as $4.95 to $5.25 lbs. From the drop down they can select Half or Whole and pay the "Down Payment" amount. We do not know until later down the road when the animal is processed what the actual wheigh will be. Once the animal is processed then we can fill what the exact pounds are at that time. We need to create a final invoice for the client showing the total pounds multiplied by the cost per pound minus the down payent amount. Example: 322 lbs x $5.25 = $1690.00 (Down Payment from Invoice) Invoice# - $ 400.00 Balance Due: $1290.00 We then need to collect that final payment either by email, applying a check, cash or credit card. When view reports we want to be able to see both the down payment and final payment under Beef Shares. You can see the site we have been working on by going to [login to view URL] . Please note there are several livestock shares we offer.
