Things to consider when you invest in a SaaS

To select a suitable SaaS vendor you need to consider vital criteria such as privacy and security, support and service, and transparency.

Find out if the provider can be trusted with data security and privacy. Do they have processes in place to safeguard your private information and data? Find about the security processes they use. This is an important aspect of a SaaS application that cannot be over-emphasized.

It is crucial that the provider offers reliable support to resolve any concerns quickly. Ask your potential vendors the following queries: Do they provide consulting and training services to assist your staff members to utilize the solution effectively? Do they have an online support center that has helpful articles and training resources? What channels of support do they offer? Do they monitor problems till they are resolved? Is customer satisfaction measured?

Does the SaaS vendor conduct their business in a transparent and open manner? You can find out by requesting them for references you can contact. Talk to existing users of the system to know about the quality of service provided. Does the vendor make public the algorithms they use in the program? Ask these questions to find a SaaS provider whom you can trust with your sensitive customer and business data.
