The term to achieve different business needs in the same process [closed]

     We are going to design a software system。 It will have access to many customer, and it will be a multi tenant model。
     Different customers may have different requirements for the same restful interface or the same business logic。      For example, for a payment action, customer A may need to “check” whether the amount is more than $10, and customer B may need to check whether the amount is more than $100。
     If it's just this problem, it's easy to solve。The difficulty is that with the use of the system, changes and differences will appear anytime, anywhere。
     Technically, we know that technologies like Java, spring IOC are all used to solve these problems。Layered mode or DDD mode can also solve some of these problems。
     In general, I want to know if there are any special books to solve these problems。
