Buy software when it fits. Build it when it doesn't.
How to decide whether to use existing software, connect your tools or build something custom.
Start with off-the-shelf software.
It's tested, supported and cheaper when it fits how you work. It stops making sense when the workarounds become the job: staff copy data between systems, key steps live in one person's head and costs keep rising. Sometimes the fix is just connecting two tools.
Build custom when the current setup costs more than building something that fits.
Where to start
List the workarounds and what they cost you when they fail.
Check whether an existing tool or a simple connection fixes it.
Only build custom if the gap is still there.
What you'll take away
How to tell a real gap from a messy process.
Questions to ask before buying anything.
Smaller options than replacing everything.
What you should own if you build.
Quick answers
When is off-the-shelf the better choice?
When your process is common and the software already does what you need. Adapting is usually cheaper than building.
Can we just connect our tools instead?
Often, yes. Connecting your CRM, accounting or forms can stop double entry without replacing anything.
What do we own if we build custom?
The code, the data and the documentation. You can keep working with us or take it elsewhere.
