Payment link
A payment link is a web address that opens a payment page for one amount, so you can collect money without a full shop.
In a simple example
You send a link to a customer on chat. They tap it, pay 15 dinars, and you see the payment.
Why it matters to you
It lets a very small business take online payments the same day, with no website.
Do not confuse with
A payment link is for one payment. It is not a whole online shop.
