When custom software beats off-the-shelf

Off-the-shelf wins when your workflow matches the product's assumptions. Custom wins when your differentiation lives in the workflow itself.

Configure before you customize. Extend before you rewrite. Build when the cost of fitting a square peg into a round hole exceeds building the right shape.

Total cost of ownership includes integration, migration, training, and the features you will never use but still pay for.

If three competitors could use the same SaaS and your advantage disappears, the software is probably not where your moat lives.
