What do you need for an online store?

Question

Online shopping

I want to open an online store of articles (my website on the WordPress engine).
Please tell me the following:
- How to make a payment WITHOUT registering on the site itself?
- After payment, the download button should appear. How to implement?
- What is the best cash register to use? Example: Yandex.Checkout

Answer 1

You need billing. This is also called a paid subscription. Or look for solutions to sell digital goods.
It's that simple, right?
Only without registration it will turn out crooked. How will you identify the client?

Answer 2

Regarding the cash desk, depending on what territorial audience you are targeting .. I use payment aggregators - Interkassa and Free-kassa. There are many payment options out there.
