Custom Internal Tools vs. SaaS ROI.
The "Build vs. Buy" framework for modern enterprise: When to buy SaaS and when custom internal tools provide the 10x ROI.
One of the most frequent questions I encounter from business leaders is: "Should we buy an off-the-shelf SaaS or build this ourselves?" In an era of SaaS proliferation, the default answer is often "Buy." However, for businesses with unique industrial workflows or specialized data management needs, "Buy" can lead to a "feature gap" that stifles growth. This framework helps you identify where custom software is an investment, not a cost.
Core: Activities that differentiate your company and provide competitive advantage. (Example: A proprietary quoting algorithm). Build these.
Context: Necessary activities that do not differentiate you. (Example: Email, Payroll, CRM). Buy these.
The cost of SaaS is more than just the monthly subscription. It includes integration effort, data export risks, and the cost of "workflow workarounds."
- Build Cost: Dev time + Maintenance.
- Buy Cost: License + Integration + Workflow Loss.
If a custom tool can reduce a critical business process from hours to minutes, or eliminate a high-frequency manual error, it provides a "Strategic Edge."
For industrial companies, this often looks like custom CPQ (Configure, Price, Quote) tools that integrate directly with their PDM and ERP systems.
“SaaS provides the foundation; custom tools provide the edge. Excellence is knowing where the foundation ends and the edge begins.”
