SaaS wins for standard business capabilities
Accounting, email, help desks, analytics, and many collaboration needs are usually served best by mature products. They provide faster implementation, known pricing, support, security investment, and established integrations without the burden of owning every technical decision.
Custom software earns its place through differentiation
Custom engineering is justified when the workflow is unique, central to customer value, constrained by repeated workarounds, or difficult to coordinate across generic tools. The business must be willing to own product decisions, maintenance, security, and continued improvement.
Compare total operating impact, not licence price alone
Model setup, subscriptions, customization, migration, training, manual work, integration, change management, maintenance, and the value of faster or better operations. A staged prototype can test assumptions before committing to a larger build.
Practical checklist.
- Map the workflow and non-negotiable requirements
- Audit credible SaaS options first
- Estimate workarounds and integration cost
- Define ownership, security, and maintenance
- Prototype the highest-risk assumption
- Choose the option with the clearest long-term operating value
