How to keep track of orders from the site and checks at the cash desk at the same time?

Question

PHP

Is it possible to go through orders and checks at the cash desk at the same time?
Task:
You need to remove the product from the site if the product is in the check or in the order.
Is there asynchronous behavior? I understand to create two different functions parsing by checks and parsing by orders, and run both functions by cron. Maybe there is another way?
Or just sichron?
