Some possibilities

Buyers' interest is automatically structured

When potential buyers go to the payment form, your referral user_id is remembered in their browser.
If they want to sell their products or accept donations using the system, they will delete the data after the slash in the address bar in order to go to the main domain and register.
When registering, all these people will register with you at your first level and will end up in your personal referral structure.

Their referrals or referrals already their referrals up to level 10 will become, including your referrals, and their referral sales or internal purchases will begin to bring you instant referral income.

This can be a very large flow. Sometimes just one interested person may be enough. Starting from it, you can automatically create a colossal structure and referral income from a variety of products, including from the products of your competitors, if you have them.
Using regular payment acceptance services, you always miss this flow. Free and unnoticed, you give it to others, developing other people's services.

Fateful recommendation

You can significantly speed up the above process by sending your referral link to one or more people who already accept donations, sell products or just want to start.

Remember, if they use third-party resources, they miss out on money and huge structures for themselves, each time giving them to others.
Any published link to purchase a product or donation is an advertisement of the domain and free advertising of the service.
Using SetHubble - the main domain of the payment acceptance site will not be available to interested people. So that they do not lose people - the transition to the main domain will be available only after they go to the payment form.

Own Company

Not only a 10-level network is structured. The system also has an infinite binary system, thanks to which you can create your own company for the sale of material and digital products, indicating cash payments + point payments for your distributors.
The binary system includes spillover and all the functions that you and your distributors will need for successful work.

You will always be in the black, even if they simultaneously start selling their products with the referral program enabled. You and your network will earn not only from your products, but also from a variety of products of their referrals up to level 10 in money + in an infinite level binary system in a point equivalent, accumulating them symmetrically and receiving money from points.
Thus, your company can eventually have millions of products.

Identify sales by Telegram messenger

Sometimes it happens that you need to sell products or access to closed Telegram chats only to Telegram users.

Using SetHubble you can easily do this by selecting the appropriate item when adding a product or donation, allowing payment only after confirming their Telegram account, which is done in a few seconds.

Use a simple API to sync sales with your system or do it manually from payment history, or Telegram notifications.
