Should I use custom software or off-the-shelf software?

The build-vs-buy decision is one of the most consequential technology choices a business makes. Here is a structured framework for making it correctly.

When Off-the-Shelf Wins

• The process is commodity -- HR benefits administration, general ledger, basic CRM
• The platform handles 85%+ of your use case without significant configuration
• The vendor ecosystem provides the integrations you need
• Your team does not have the bandwidth for software procurement and implementation
• Speed to launch is more important than perfect fit

When Custom Software Wins

• The process is a source of competitive advantage -- your workflow is better than competitors' and the software should reflect that
• Off-the-shelf licensing exceeds $50,000/year for the capabilities you need
• Data ownership is a compliance requirement (HIPAA, defense contracting, financial regulation)
• You have evaluated 3-5 platforms and all of them require significant workarounds
• The process involves AI automation that off-the-shelf tools cannot handle

The Hidden Cost of Off-the-Shelf

SaaS platform costs compound: per-seat licensing, add-on modules, integration middleware, and annual increases. A platform that costs $30,000/year at launch often reaches $80,000-$150,000/year at scale. A custom-built equivalent paid for once at $150,000 with $10,000/year in maintenance frequently delivers a lower total cost of ownership over a 5-year horizon.
