The most popular purpose an organization creates or gets a custom product is that it's special to their organization and if the software is designed effectively it will improve the business' productivity and create its own competitiveness edge.
Moreover, creating a custom software requires a great upfront cost and it also takes a long time to build a proper one.

There would be maintenance costs in the long run but it wouldn't be as enormous as it was in the building and the process of creation. But, the more significant than cost, is the long-term benefit it brings to the business.
A specific application will improve the workflow of the company, allow the company to retain space with the rate and volume expansion, all of which would help bring financial benefits and distinguish the business from other competitors.
