Real-revenue cases
A WordPress theme business running since 2009 that has accumulated 45,000+ historical paying customers; it booked $13.7k revenue and $13.4k profit over the last 12 months and is now being sold together with its source code, domains and email list.

Customers pay for WordPress theme licenses — one-off or per-product digital goods — with payments collected through Stripe.
