Where it usually starts
A small software vendor or a designer selling templates usually starts with a payment link and a file attached to an email.
- It works for the first hundred sales.
- Then a customer asks for the file again six months later and support has to find the original order; another forwards the download link to a forum and the file circulates freely; a third bought a single-site licence and is running it on twelve sites, and nobody can tell.
- A new version of the product ships and every past buyer has to be emailed by hand, with a fresh link, from a mailing list that was never quite in step with the order list.
