How to make a transaction control tool between legal entities?

Question

Law in IT

We are doing a project in which there will be billing between legal entities.. For example, a person can buy a service from another, issue an invoice. in our report, reduce the amount by several times than it actually is.

Maybe there are some tools?

Since this is not online billing, it will probably not be possible to control by API

Answer 1

No way. You can only enter into an agreement with them and engage in control within your platform. Any operations to spy on your clients outside of your platform will be considered illegal and you will only be able to find out and prove it in court if someone "leaks" the relevant information with evidence to you

Answer 2

blockchain helps a lot in this))
copy the principle of an online cash desk - everything about transactions is sent to your server
there is no Internet - the code is archived with your key, etc.
in short, programmatically, you can come up with a lot of things, but what's the point - if you are legally and physically weak

Answer 3

The first option is through the blockchain.
The second - through an intermediary in the form of an Escrow service

Answer 4

No way.
You don't have anything yet. You would take care that at least some companies begin to use you and not worry about who will throw whom

Answer 5

Obviously, within the framework of the contract that you enter into with everyone who joins your platform. The only question is - what for are you? If two legal entities can agree without you, they will agree without you, and this is not a scam, but an ordinary normal business.

Answer 6

It’s hard to say without knowing the product itself, but I see two schemes - either you ensure the security of the transaction, protecting both legal entities from the fact that another legal entity will throw it, or you give some unique amenities and benefits that they will lose by leaving your platform.
Companies cannot be prohibited from operating directly.
Work through the carrot, not through the stick.
