If I recall from a previous company, we used Stripe but would sometimes need to manually invoice a customer and they had the option to generate a unique link to a decent looking invoice page where the customer could fill it out, have everything logged and handled by Stripe, and that was the end of the story.

It seemed awfully convenient for one offs/corrections for large customers when things done need to be slick and automated.
