Private project for Toinnisfree - Part 2 -- 2

I have a WooCommerce Subscriptions install needing customising. I need two fields of meta data added to the User Meta when an order is completed that is a Subscription product. ONE of the meta fields must be modified when the subscription EXPIRES. ALSO: Currently the Pro-Rata Calculation of the payment process is set to calculate the price remaining based on days and amortising the amount across the rest of the subscription. I need this changed to charge a FLAT FEE. This is NOT as simple as it sounds. The site is set to ANNUAL RENEWAL date - however this separates the payment from the expiry of the subscription. I need these to match exactly - in other words the EXPIRY of the SUBSCRIPTION must be the day before the ANNUAL RENEWAL - these need to match. If you have experience with WooCommerce and WooCommerce Subscriptions please quote as this is an immediate hire. You will need to have ADVANCED experience with Woo as this takes the product out of it's original scope. Further Requirements: ---------------------------- Wordpress Groups. WooCommerce for Groups. WooCommerce Subscriptions. Currently when manually adding an Order to a User via the WooCommerce Orders interface the Subscription is not changing the Group. This needs to happen when editing or creating an Order.
