Choosing between a custom ERP and an off-the-shelf product is one of the biggest decisions a growing company faces. Packaged solutions launch fast but may impose workflows that don't fit your business, while a custom system matches your operations exactly at a higher cost and timeline.
A practical rule: buy what is standard (accounting, payroll) and build what represents your unique competitive edge. Often the best answer is a hybrid that connects packaged tools to custom modules through APIs.
