Automatically add credit on sale

Hi there. Amazing plugin! Is it possible to add credit to a customer account automatically when a sale goes through? An example:

I sell a chair for ￡50. The chair maker has an account which I would like to pay ￡45 into when the chair is sold.

Currently I have a cost of goods plugin so have the cost price (￡45) and retail price (￡50) set up. Ideally I would like to automatically use the cost price as the amount added to the wallet. Is this possible?
