Custom Software: When It Pays Off – and When Off-the-Shelf Is the Better Decision
Custom software is built for one specific client, not an anonymous market. It pays off when a process explains your margin, when three or more systems have to stay in sync, or when many people use it: license costs scale per head, development costs do not. For non-differentiating processes, off-the-shelf wins clearly.
