The Traditional Decision Framework
For years, the advice was simple: buy unless you have a compelling reason to build. Off-the-shelf SaaS was faster, cheaper, and less risky than custom development. But AI-assisted development has changed the equation.
When Buying Makes Sense
- The problem is common and well-understood across industries
- Multiple proven vendors exist with established track records
- Your workflow can adapt to the software without major disruption
- You need the solution immediately
- The total cost of ownership is predictable and acceptable
When Building Custom Makes Sense
- Your workflow is unique and provides competitive advantage
- Off-the-shelf tools require expensive workarounds or integrations
- You're paying for features you never use
- Data security or compliance requires full control
- The problem spans multiple tools that don't integrate well
- You want to own the solution, not rent it forever
How AI Changes the Calculation
In experienced hands, AI development tools sharply reduce custom build time and cost. Projects that used to take a year or more can now be delivered in months, often for much less. That makes custom development a lower-risk choice than it used to be.
The Hybrid Approach
You don't have to choose all-or-nothing. Many businesses use off-the-shelf SaaS for commodity functions (email, accounting) while building custom solutions for their unique operational workflows. This gives you the best of both worlds.
Questions to Ask Before Deciding
- Does this workflow differentiate our business?
- Are we forcing our process to fit the software, or vice versa?
- What's the true total cost of ownership over 3 to 5 years?
- How much time do we spend on workarounds?
- Do we have the internal capacity to manage this?
