Build in-house or commission BTO: the real cost comparison
Every Lagos operator with a technical problem faces this decision. Hire a developer and build it yourself, or bring in a team that has built it before. Here is the numbers-based comparison.
Side-by-side comparison
| Metric | Build In-House | Commission BTO | Better |
|---|---|---|---|
| Initial cost | ₦500,000-₦2,500,000 (developer hire or freelance) | ₦249,900 audit (credited back on build) + scoped build cost | BTO wins |
| Time to first working system | 4-12 weeks (hiring, onboarding, building) | 5 working days for audit; 2-6 weeks for build | BTO wins |
| Maintenance | Continuous. AI APIs change. Workflows break. You own it. | 2 weeks post-launch support included. System documented for your team. | BTO wins |
| Hiring risk | Developer may leave. Knowledge walks out the door. | System is documented. Your team can run it. No single point of failure. | BTO wins |
| Lagos operational context | Depends on the developer. Most are not Lagos-business-native. | Lagos-first. Built for WhatsApp, bank transfers, mobile-first workflows. | BTO wins |
| Tool selection | Developer picks what they know. May not be optimal. | Tool-agnostic. We pick what fits your stack, not what is easiest for us. | BTO wins |
| Ongoing cost | Salary, benefits, tooling subscriptions, cloud hosting | Zero after handover. You own the system. No retainer. | BTO wins |
| Full control over code | Yes. You own the source code. | Yes. You own everything we build. Full source code, full documentation. | Tie |
| Speed of iteration | Faster for small changes if developer is in-house | Requires a new engagement for major changes | Build wins |
The hidden costs of building in-house
Hiring a developer looks straightforward on paper: find someone competent, pay a salary, get your system built. In practice, the hidden costs stack up quickly. Recruitment takes weeks. Onboarding takes more weeks. AI development requires specialised knowledge of LLM APIs, prompt engineering, workflow orchestration, and integration patterns that most generalist developers do not have on day one.
Then there is retention. Lagos developer turnover is high. When your developer leaves, they take the undocumented knowledge of how your system works with them. Your automation goes from an asset to a liability overnight. BTO documents everything and hands over source code, playbooks, and runbooks. There is no single person whose departure breaks your system.
When building in-house makes sense
Building in-house can be the right call if you meet all three of these conditions: (1) you already have an experienced developer on your team who has built AI integrations before, (2) your automation needs are narrow and well-defined, and (3) you have the appetite to own ongoing maintenance, API updates, and workflow debugging indefinitely.
If any of those conditions is false, commissioning BTO is likely faster, cheaper, and lower risk. The audit answers this definitively: we map exactly what needs building and tell you honestly whether it is a build-it-yourself job or a commission-us job.
The BTO difference: you still own everything
A common misconception is that commissioning an agency means giving up control. With BTO, you own every line of code, every workflow, every integration. The system is built in tools your team can access and modify. Documentation is written for your staff, not for engineers. There is no vendor lock-in, no proprietary platform you cannot leave, and no ongoing retainer.
We build the system, document it, train your team, and step back. You run it. If you want changes later, you can make them yourself or engage us again. The choice is yours.
