AbleCommerce Shopping Cart Software

Hello,
we are in a situation where I will have to implement the following using AbleCommerce.

We have a website where differnet types of organization can create their profile. Anyone can sponsor them by purchasing their item. For this purpose I use Ablecommerce shopping cart.I use Authorize.Net as gateway and Paypal as payment method.The site owner use Authorize.net account and every organization must have a PayPal account.

Now we want to do the following.
When items are purchased, the full proceeds are deposited to website Authorize.net account. At regular intervals (e.g., monthly), 50% of the proceeds are paid to the sponsored organization Paypal account.When this 50% is paid, obviously, the revenues should be marked as “complete” so that further payments aren’t made on those revenues. The other 50% is to remain in website Authorize.net account.

I would really appreciate if you could provide some advice on how to accomplish the above.
Note: We were able to use the website mechanism you suggested before to call the AbleCommerce APIs, thanks a lot for your advise.
Thanks in advance for your help.

You can create a new order status from Administration > Configure > Order Statuses. Now when ever order is competed and you have paid organization then you can simple change order status to your custom order status to keep track that you have paid their share.
