Software development
Should you buy existing software or build custom software for your business?
It is the 'rent or build your own house' debate, but for your business. One side says just subscribe, it is cheaper. The other says build yours, be free. Both sides are right, annoyingly. Here is how to know which one is right for you.
What is the difference between off-the-shelf and custom software?
Off-the-shelf software is a ready-made product built for thousands of businesses at once. You sign up, pay a subscription and start using it today. Think of accounting apps, popular CRMs and online store builders. It is the suit you buy off the rack: decent, available now, and made for an average body that is not exactly yours.
Custom software is built for one business: yours. It follows your steps, uses your terms and connects to the tools you already have. It is the fundi-made suit. It takes fittings and patience, and then it fits like nothing else.
Neither is 'better'. They solve different problems.
How do buying and building compare?
| Compare | Buy off-the-shelf | Build custom |
|---|---|---|
| Upfront cost | Low. Often a free trial | Higher. You pay for the build |
| Ongoing cost | Subscription forever, often per user | Hosting and optional support |
| Time to start | Same day | Weeks, depending on scope |
| Fit to your process | You adapt to the software | The software adapts to you |
| Flexibility | Limited to the vendor's settings | Change anything you can pay for |
| Scalability | Easy, but each new user costs more | Grows in stages you choose |
| Maintenance | The vendor handles it | You arrange it, usually a monthly plan |
| Ownership | You rent access | You own the system |
Which one costs more?
In month one, custom costs more. Over three years, it is a real contest, and here is why.
Subscriptions look small because they are quoted per user, per month, usually in dollars. Then you grow. Five staff become fifteen. You need the feature that lives in the 'Pro' plan. The shilling has a mood swing. The bill you barely noticed is now a line item with opinions.
Custom flips the pattern. You pay more at the start, then far less to keep it running. At CEKAL CREATIVES, a first version costs KSh 20,000 to 35,000, for example KSh 25,000 for an invoice and quotation system or KSh 30,000 for a basic CRM. Monthly support is KSh 5,000 to 8,000 if you want it. Hosting and third-party services are separate.

Which is more flexible?
Custom, by a distance. With ready-made software you get the features the vendor decided most customers need. If your business does something different, you bend your process to fit the tool, or you invent a workaround involving a spreadsheet and prayer.
This matters a lot in Kenya. Plenty of global products do not handle M-Pesa properly, do not understand how you quote and collect deposits, or have never heard of your industry's paperwork. Custom software can treat M-Pesa, WhatsApp and your exact approval steps as first-class citizens. See how we do that in quotations and payments.
Which one scales better as the business grows?
Both scale, in different ways. Off-the-shelf products are built to handle huge numbers of users, so they will not buckle. But the price scales with you, and you can hit a ceiling where the feature you need simply does not exist.
Custom software scales in the direction you choose. You start with a small first version, see what your team really uses, then add the next piece. The risk is building too much too early. The cure is starting small on purpose, which is how our product-minded execution works.
Who handles maintenance and updates?
With bought software, the vendor does. Updates, security and backups are included in the subscription. That is a genuine advantage, and it is what you are paying for every month. The flip side: the vendor can also raise prices, remove a feature you love or shut the product down, and you get an email about it.
With custom software, maintenance is your call. You can take a monthly plan or pay for changes as they come. Ask for this to be spelled out before the build starts, and make sure you receive the source code and access to the hosting. Ownership you cannot log in to is not ownership.
When does buying existing software make sense?
- Your needs are standard: basic bookkeeping, email, payroll, video calls.
- A product already fits how you work, and your team likes it.
- You need something running this week.
- You are still figuring out your process and it changes every month.
- The total subscription cost is small and will stay small.
If that is you, buy. Seriously. We build software for a living and we will still tell you not to build what you can rent for the price of lunch.
When does custom development make sense?
- Your process is unusual, and it is part of why customers choose you.
- You are paying for three or four tools that do not talk to each other, and staff retype the same data in each.
- Per-user fees are rising faster than your revenue.
- You need local integrations such as M-Pesa, WhatsApp or SMS to work exactly your way.
- Your data is sensitive and you want to control where it lives.
- You have tried the popular products and keep fighting them.
There is also a middle path, and it is underrated: buy the standard parts, and build only the piece that is unique to you. Keep the accounting app. Build the job-tracking system your industry does not have. See examples on our business systems page.
How do you decide? A five-question check
- Does a ready-made product cover at least 80% of what you need, without painful workarounds?
- Will the subscription still be affordable when your team doubles?
- Does it handle your payments, especially M-Pesa, the way your customers actually pay?
- Can you get your data out if you leave?
- Is the missing 20% a nice-to-have, or the thing that makes your business different?
Mostly yes, and the missing part is minor: buy. Several no's, or the missing part is your secret sauce: build, and start with a small first version. Still unsure what you even need? Begin with what business management software is.
Quick answers about buying vs building software
Is it cheaper to buy software or build it?
Buying is cheaper at the start. Building can be cheaper over several years, because subscriptions are charged per user every month while custom software is paid for mainly once. Compare the three-year totals for your team size.
What are the disadvantages of off-the-shelf software?
You adapt your process to the product, pay ongoing fees that rise with each user, depend on the vendor's pricing and roadmap, and may find that local needs such as M-Pesa are poorly supported.
What are the disadvantages of custom software?
It costs more upfront, takes weeks rather than hours to start using, and needs someone to maintain it. Starting with a small first version reduces all three risks.
How much does custom software cost in Kenya?
At CEKAL CREATIVES in Nairobi, a first version of a business system costs KSh 20,000 to 35,000. Software maintenance is KSh 5,000 per month, or KSh 8,000 per month with minor improvements. Hosting and third-party fees are separate.
How long does it take to build custom software?
It depends on the scope. A narrowly scoped first version is the fastest route, because it covers one workflow with an agreed feature list. The timeline is agreed in writing before work starts.
Can I start with bought software and switch to custom later?
Yes, and it is often the smartest path. Use a ready-made product while you learn what you need, then build custom once your process is stable. Check early that the product lets you export your data.
