You need software to run part of your business. Maybe you've already tried a few tools and nothing quite fits. Maybe you're drowning in spreadsheets. Maybe a well-meaning friend said "just get a developer to build it."
The answer isn't always custom software. Sometimes it is. And sometimes the right answer is somewhere in between. Here's a practical framework for deciding.
Every business software decision falls into one of three buckets:
None of these is inherently better than the others. The right choice depends on your problem, your budget, and where you are as a business.
If your problem is common, the solution probably already exists — and it's probably good. Thousands of businesses have the same need, so a vendor has built a polished product, hired a support team, and spread the cost across all of them.
Buy when:
Good examples: Xero for accounting. Mailchimp or ConvertKit for email. HubSpot or Pipedrive for sales CRM. Monday.com or Asana for project management. Shopify for e-commerce. These are solved problems — you'd be wasting money building your own version.
Honestly, if a well-known SaaS tool does 80% of what you need and the other 20% isn't critical, just use the SaaS tool. Pay the subscription. Move on to the parts of your business that actually need your attention.
No-code sits in a useful middle ground. You get more flexibility than off-the-shelf SaaS without the cost and commitment of custom development. It's particularly good for testing ideas.
Build-lite when:
The limitations: No-code tools hit a ceiling. Complex business logic gets messy. Performance slows as data grows. You're still dependent on the platform — if Airtable changes their pricing or API, your "custom" solution changes too. And the per-seat costs for tools like Airtable can climb quickly once you have more than a handful of users.
Think of no-code as a proving ground. It's a great way to figure out what you actually need before you invest in building it properly.
Custom software makes sense when your needs are specific enough that nothing off the shelf fits well, and significant enough that the investment pays for itself.
Build when:
Work through these questions in order:
The smartest businesses don't go all-in on one approach. They buy for the common stuff and build for the parts that make them different.
Use Xero for accounting — nobody needs custom accounting software. Use Mailchimp for newsletters. Use Shopify for your storefront. But that client portal your customers keep asking for? The commission tracker that doesn't exist for your industry? The internal dashboard that pulls data from all your other tools? Build those.
Custom software doesn't mean replacing everything. It means filling the gaps that off-the-shelf tools can't reach.
Here's a realistic comparison for a small business with 10 users needing a workflow management solution:
The numbers shift depending on complexity and team size, but the pattern is consistent: SaaS has the lowest entry cost but the highest long-term cost. Custom has the highest upfront cost but flattens out. No-code sits in between — cheaper to start, but can get expensive and fragile as you scale.
There's a gap in the market that most businesses fall into. You're too complex for off-the-shelf SaaS — your workflows don't fit neatly into any product. But you're too small for the big development agencies who charge £50,000+ for a project and want a six-month timeline.
This is the missing middle. Businesses with real software needs but realistic budgets.
That's exactly where solo developers and small studios operate. We build focused, purpose-built tools without the overhead of a 20-person agency. Fixed prices. Clear scope. Software that does exactly what you need and nothing you don't.
You don't need an enterprise solution. You need a tool that fits your business the way your business actually works.
If you're reading this, you probably already know that off-the-shelf isn't quite working. Maybe you've been living with workarounds for months. Maybe you've tried three different SaaS tools and none of them stuck.
Here's what I'd suggest: don't start by looking at software. Start by writing down the process. What actually happens, step by step, when you do the thing that needs to be better? That's the brief. That's what tells you whether to buy, build-lite, or build.
