This is the same question as when should you build, written for teams already comparing quotes. Off-the-shelf is better when you can adopt the vendor’s process. Custom is better when adopting their process would erase how you make money or stay compliant.
A blunt comparison
| Off-the-shelf | Custom | |
|---|---|---|
| Time to first use | Usually faster | Slower by design |
| Fit | You adapt | It adapts |
| Ongoing cost | Licences + workarounds | Ownership + change |
| Differentiation | Low | High if you fund it |
| Exit | Export quality varies | You own the source if the contract says so |
A school choosing ERP vs a narrow app is a specialised version of this — school ERP vs school management software.
FAQ
Is a heavily customised package “custom software”?
It is often the most expensive hybrid: you still pay licences and you now own a fork the vendor will not support cleanly. Prefer configuration, or a true custom boundary.
If you need software built around a real workflow — not a stack of disconnected tools — see Devzin application development or start a conversation.
