I know there exist monolithic programs out there for running your entire business. But they often require you to run your business their way. Little tailoring is possible. Maybe you'd like to maintain control of your own business, and not spend three years of agonizing changeover to the new miracle. Look at plumbing, autos, and armaments for examples.
Costs only go down, and reliability up, when manufacture is controlled and reduced in variety.
This looks much like Track 5 here, on collaborative processes. It might be the most important venture you have going. The IEEE, ACM, and other professional societies should mostly quit the books business and serve as guides and repository agents for software piece parts. Have them bring the whole world into the act. Have your credit card ready to buy a chunk of program off the shelf, doing what you want to do.
