Is there a way to have an automatic paid tag applied after successful manual payment

When processing credit card purchases, I have the system automatically add a paid tag as soon as the transaction goes through. When processing manual payments (i.e., check payments) I cant figure out how to have the system automatically added a paid tag. Is there a way?

I am assuming here that you are making an order on the contact record.

You can have a product purchase goal listen for that particular product and apply a tag.

Make sure that in the product purchase goal you tick all the options.
