Vibe coding, a developer or off-the-shelf software? How South African SMEs should choose
Three ways to get software. Each is the right answer for some problems and the wrong one for others.
Every growing business reaches the point where spreadsheets and WhatsApp groups stop working. You have three broad options: buy off-the-shelf software, hire a developer or agency to build it, or build it yourself with AI tools, which is vibe coding. Here is how to choose.
Off-the-shelf software
Accounting, payroll, point of sale, email and most CRMs are solved problems. Mature products exist, they are tested by thousands of businesses, and they handle the hard parts such as tax rules and security for you.
Choose it when your process is standard, the product fits at least 80% of what you need, and getting it wrong would be costly (payroll, accounting, payments).
Watch out for per-user pricing that grows with your team, subscriptions billed in US dollars, features you pay for but don't use, and bending your business to fit the software.
Hiring a developer or agency
A good developer or agency builds exactly what you need, takes responsibility for quality and security, and can handle complex logic, integrations and scale.
Choose it when the system is core to how you make money, it handles payments or sensitive information at scale, it needs complex integrations, or it must be reliable for many users from day one.
Watch out for cost and timelines, depending on one person who knows the code, and briefs that are too vague. A clear written plan reduces all three.
Vibe coding it yourself
AI app builders and coding assistants let a business owner or a small team build custom software quickly and cheaply, especially the internal tools that off-the-shelf products don't quite fit: job cards, bookings, stock trackers, approvals, client portals and dashboards.
Choose it when your process is specific to your business, the tool is mainly for your own team, you want to try an idea quickly, or the alternative is another spreadsheet.
Watch out for credits spent on prompting again and again, missing permissions, POPIA gaps, and nobody owning the app once it is live. See how to stop burning credits and the POPIA checklist.
A quick way to decide
Ask these questions in order:
- Is there a mature product that fits? If yes, buy it. Don't rebuild accounting or payroll.
- Does it move money or hold sensitive information at scale? If yes, use a developer, or at least have one review what you build.
- Is it specific to how your business works, and mainly used by your team? Vibe coding is often the fastest, cheapest route.
- Not sure? Vibe code a first version to learn what you actually need, then decide whether to keep it, buy something or brief a developer. That first version makes a far better brief.
The approaches combine well
Most businesses end up mixing them: off-the-shelf accounting, a vibe-coded job card app for the team, and an automation tool connecting the two. And a growing number of developers now use AI tools themselves, so a clear plan helps whichever route you choose.
The common thread is the plan. Whether you hand it to an app builder, a developer or a software vendor's sales team, knowing your roles, records, screens, rules and automations is what gets you the right system.
Questions
Is vibe coding cheaper than hiring a developer?
For small internal tools it usually is, especially with a clear plan that keeps credits low. For complex, high-risk or large-scale systems, a developer's experience is worth the cost.
Can a developer take over an app I vibe coded?
Often, yes, if the tool lets you export the code and your data is in your own database account. A written plan or spec makes the handover much easier.
Should I vibe code my accounting or payroll?
No. Use established accounting and payroll software that keeps up with South African tax rules. Vibe coding is better suited to tools specific to how your business works.
