Pay Suppliers only when the related Customers pay the Business

Hello,

We have a requirement and not sure on how to achieve the solution i.e Supplier should only get paid when the related Customer pays the business.

To explain with an example, ABC is a supplier and XYZ is a customer to the business and due to some requirement business must make sure before paying ABC they are paid from XYZ, if business owes $1000 to ABC, the business should make sure that they have received the same amount from XYZ before paying ABC.

How to make sure if the related Customer(XYZ) has paid the business before paying the supplier(ABC). Is there a way to achieve this requirement.
