Point-to-point connectors can be very convenient and cost-effective upfront, much like vendor-built integrations. They were usually domain-specific, however, and were not designed to handle broader business processes with versatility. Also with any conceivable permutation of business applications, it is difficult to build individual point-to-point connectors with thousands of cloud applications available today.

Anyone may create a core integration of their own. Custom integrations can be very effective through the leverage of code and APIs and are often the chosen route taken by many operating teams. However, since they need qualified technical services and are very time consuming, in a scalable, robust way, it is difficult for them. Integration, for example, includes essential features such as error handling and guaranteed data delivery, which are not easy to construct for each integration from scratch.

For growing enterprises, using an automation framework makes sense as it standardises how to track, retain, and upgrade processes through applications that are added and updated every day. Companies can incorporate applications into business processes easily, and they no longer need to reinvent the wheel with the functionality of building integration. With the right iPaaS, integration can be designed, controlled, and maintained by both line-of-business users ('citizen integrators') and technical users ('integration professionals').
