This happens A LOT with developers and development teams. This has happened to me a number of times. Here’s the deal with this, you must go through the process of validation and especially the process of fully understanding your costs. Very often a SaaS will have ongoing operational costs as well as hard costs, that can wrack up fast. You’ll have developers, integrations that change regularly that you have to keep up with, compliance to laws, insurance, the cost of support, legal fees, and much more. Even if you have the system built, you need to remember that you have costs that you will incur on a monthly basis just to keep things moving, so you’re going to need sales. So you still need to do a full validation process.
