Universal billing?

Question

Billing systems

Perhaps I want something strange
. Billing is required, but not the one that counts traffic or phone calls, but something more universal.
For example, there is some kind of service. He provides certain services for money. Services have tariffs (for example, a day costs so much, a month costs so much).
There is a user. He has a personal account. Money is debited from this personal account and services are activated or deactivated for a certain time. After the paid period, the services are disabled.
So.
We need some kind of universal billing that can:
* Keep personal accounts of users
* Have an interface in which employees can work
* Save the history of financial relationships (transactions)
* Manage the status of services (activated / not activated)
* Have an api (so that you can integrate it into the service itself)
Ideally
* Be able to communicate with all sorts of 1s and other systems
* Generate accounts for legal entities * Be able to connect with all
sorts of robocash and other kiwi
