This. Reinventing the wheel in business context IMOH should be only if:

- you can afford it (money)

- you have enough time or your customer can wait

- provide significant benefit to you or your customers (have nothing better to do)

- you don't have fierce competition in your domain

- you are pretty much retired (or could) and treating it more like art/craft/passion project

I compare it with building some custom made designer house and furniture. Many would want that, only some can afford it, even less will pay for it.
