Usman that is a deep rabbit hole to go down.  There is no easy or "Always" do it this way answer.

If you only ever take one payment - that would probably be over kill.  If you receive multiple payments then it is definitely the way to go.

I see in your courses you are up to Beginner 2.  I don't know your experience outside of what I see here.  I recommend continuing at least through Expert 1 or 2 before you jump into your project.  Get the basics down first.

There is also a ton of free video resources in the TechHelp. Even better is the Silver or Gold Membership.  Those take you beyond and more into the deeper levels of what you can accomplish.

If you have specific questions ask away, we're here to help.

Thanks, I got a feel from your answer.

Nevertheless, when you're ready, partial payments are covered in Access Developer 7.
