Pay per Credit Card manually (not linked with a shop)

Hi,

I have a special question and hope you can help me.

I have implemented an auction platform where users can sell and buy items. Once an auction has finished, I like to charge the sellers a commission as he found a buyer thanks to my platform.

The default payment set up of the auction platform is that the buyer has to pay the commission. For my business case, that doesn’t make sense. It should be the seller. Therefore, I look for another solution.

Once the auction has finished, I send manually a link to the seller. When he opens the link, he gets to a page where a short description explains him about the sold product and what kind of commission he has to pay. (I have to save each time manually the description and amount). He then can pay by credit card. After this, I see in a backend that this user has paid and can close the issue.

– With which plugin / software / tool etc. can I implement a solution like described above?
– Can I edit Stripe so that it works like needed?

I look forward to your answer.

Regards,
Philipp
