Customer doesnt know how to build.

In a business, customer dont tell the correct production amount as what is wrote in the contract.

I think Patrick is correct when he mentioned that the only way to get the information is with remote attestation. But that can become complicated and if the customer is determined they may break the scheme.

Can you describe the business model in more detail? It appears that you have a royalty-based agreement with the customer, but the customer is being dishonest. Maybe others have a better idea of what kind of business arrangements can work better in the future - Upfront payment for porting, time-based support contract, etc.
