Build vs Buy Software: How to Decide
Build when the software is a competitive advantage or nothing off-the-shelf fits; buy when a mature product solves a common need well. The real cost of building isn't just the build, it's the ongoing ownership, so build deliberately and buy the rest.
Build vs Buy
| Build | Buy | |
|---|---|---|
| Speed | Slower to first value | Fast |
| Fit | Exact to your needs | As close as the product gets |
| Cost shape | Upfront build + maintenance | Recurring subscription |
| Control | Full | Vendor-dependent |
| Best for | Differentiators, odd workflows | Commodity needs |
| Risk | Execution risk | Lock-in and roadmap risk |
Build when
- It's a competitive advantage, not a commodity.
- No off-the-shelf tool fits without painful workarounds.
- You need to own the data, IP, or integrations.
- Subscription costs no longer make sense at your scale.
Buy when
- A proven product already does it well.
- It's a commodity need, not a differentiator.
- Speed matters more than a perfect fit.
- You don't want to own maintenance.
Frequently asked questions
What's the hidden cost of building?
Ownership: maintenance, security, hosting, and the team time to keep it healthy. We factor that into any build-vs-buy conversation honestly.
Can we do both?
Almost always, and you should: build the differentiators, buy the commodities. Few companies should build their own email or calendar.
Will Laxaar tell us to buy?
Yes, when buying is smarter. We'd rather give you the right answer than sell a build you'll regret.
