This question comes up in almost every conversation I have with business owners. And most of the time, they're asking the wrong version of it. The real question isn't "should I hire a developer or buy SaaS?" — it's "does this problem require a custom solution, or has someone already built one?"
That reframe changes everything. Here's the framework.
Start with the SaaS assumption
Default to existing software first, always. Before you consider hiring a developer for anything, spend two hours searching for a tool that already does what you need. Chances are, it exists. Software development is expensive, slow, and creates ongoing maintenance costs that most business owners don't account for up front.
A rule of thumb: if your problem is common, there's a SaaS for it. Invoicing, scheduling, CRM, project management, email marketing — these are solved problems. Don't rebuild them.
When SaaS genuinely doesn't work
There are real situations where custom development is the right call:
Build custom when:
- The process is genuinely unique to your business model
- You've outgrown existing tools and switching costs are real
- The competitive advantage is in the software itself
- You need deep integration between 3+ systems that no tool supports
- The cumulative cost of SaaS tools exceeds the build cost within 18 months
Buy SaaS when:
- The problem is common across industries
- Your team needs to be up and running in days, not months
- You don't have technical staff to maintain custom code
- You're still finding product-market fit
- The budget for development exceeds $10k and ROI is unclear
The hidden cost of custom development
Most business owners only think about the build cost. But custom software has four cost components: build, maintain, update, and replace. A $20,000 project that costs $2,000/month to maintain and needs a major update every 18 months is actually an $80,000 investment over three years.
"Custom code is a liability as much as it is an asset. Make sure the asset is worth the liability."
What about no-code and low-code?
The middle ground — tools like Bubble, Webflow, Glide, and Retool — has expanded dramatically. For many use cases, these platforms give you 80% of the flexibility of custom development at 20% of the cost and time. Before you hire a developer, explore whether a no-code platform solves your problem.
The caveat: no-code platforms have limits. As your scale grows, you may hit those limits. Build with a clear understanding of what happens when you do.
