Saved maintenance cost: as a third party, saas would save the maintenance cost, bugs and error removal cost during the usage of system.
Comfortability in deployment : the employees only have to get the system and initial access. They don’t have to waste time in its deployment. Until end of subscription, any employee according to status can access and use the system.
Accessibility: all employees and users need a good internet connection and browser to access the system. This is generally available on a wide range of devices and from anywhere in the world
Scalability: the company can change or adopt new subscription offers according to their needs.

Security : access management and the privacy of sensitive information is a major consideration around cloud and hosted services.
Connectivity problems : SaaS model is based on web delivery, if user’s internet service fails, they will lose access to software or data
Lack of control : the system is controlled by third party which is not good approach for the service department.
Performance : the performance can be reduced such as latency rate, speed and reliability by third party control.

Recommended in-house and reasoning of choosing it
I would highly recommend to choose in-house customized software because
The warehouse needs a highly customized design and system so designer and developers can make each screen and design according to their users.
Comfortable interface can be developed so that all the users, employees and managers learn to use the system.
The system has to schedule services and have to generate reports, knowledgeable experts can provide support in case of any technical issue in system.
