Proposal to reintroduce the prepaid payment option

ZAP-Hosting used to offer the option of paying for servers and services not only via contract models, but also via a prepaid model. This feature was extremely attractive to many users (myself included) as it offered more flexibility and was ideal for occasional users or short-term purposes.

Why reintroducing prepaid would make sense:

1. flexibility for customers: Many users only want to use servers on a project-by-project or temporary basis without committing to a contract right away.

2. low barrier to entry: New or cautious customers prefer to test with prepaid instead of an ongoing contract. This can lead to more new customers.

3. customer satisfaction & retention: More choice generally increases satisfaction.

4. many customers have greatly appreciated the function in the past.
