Two developers quote you for what sounds like the same app. One says ₦900,000. The other says ₦4.5 million. Same screens, same idea, same three-month timeline. Naturally, the cheaper quote wins.
Eighteen months later, it is usually the cheaper quote that has cost more.
We say usually deliberately. A low quote is not automatically a bad one. Sometimes a lean quote is exactly right: a narrow MVP, one platform, no unnecessary features. The problem starts when a quote is cheap because the scope is invisible, not because the scope is disciplined. The real danger in a cheap app quote is not the price. It is the cost of everything the quote leaves out — and the cost of owning the app after it is built.
Two quotes for the same app are rarely the same app
A quote is a price attached to a set of assumptions you never get to see. Which platforms will it run on? Is there a real backend behind it, or a screen-deep prototype that looks like an app in a demo? Who owns the source code when it is done? What happens the day after launch?
A lower number usually means a narrower set of assumptions — not a sharper pencil. The cheap quote is often cheaper because it quietly leaves out the things that keep an app alive once real users touch it.
The decision hiding inside the quote: native or cross-platform
This is usually the biggest cost decision inside an app quote, and many quotes hide it.
Native means the app is built separately for each platform — Swift for iPhone, Kotlin for Android — as two distinct codebases. It offers the best performance, the smoothest animation, and the deepest access to device features.
Cross-platform means one codebase — built with a framework like Flutter or React Native — that runs on both iPhone and Android. It is often cheaper to build and maintain because one team works from one shared codebase instead of rebuilding every feature twice.
Neither is better in the abstract. Native earns its premium for graphics-heavy or performance-critical apps — think real-time animation, gaming, or heavy hardware use. For the apps most Nigerian SMEs and early startups actually need — a booking tool, a store, a service marketplace, an internal operations app — cross-platform is usually the rational default.
The question is not which technology is fashionable. It is what your business can afford to build, maintain, and improve. A quote that does not say which route it takes, and why, is hiding one of the most expensive decisions in the project.
How much should a mobile app cost in Nigeria?
There is no authoritative market average for this, so treat the figures below with care. They reflect the ranges Nigerian agencies and freelancers publicly advertise — orientation, not a price list, and not market averages. Real cost swings enormously with scope, team, and complexity.
- Basic / MVP: a few screens, simple logic, one platform or cross-platform — publicly advertised range: ₦300,000–₦1,500,000.
- Mid-complexity: user accounts, payments, chat, dashboards — publicly advertised range: ₦2,000,000–₦8,000,000.
- Fintech / complex: wallets, KYC, security layers, heavy integrations, compliance — publicly advertised range: ₦10,000,000–₦20,000,000+.
One thing the table hides: the same app built natively for both iOS and Android sits at the higher end of its band, because it is effectively two builds wearing one brief.
The cost that never appears on the quote
Here is the part that catches founders out. The build price is a down payment. Across three to five years, the cost of owning a working app often matches or exceeds the cost of building it:
- Maintenance. A common vendor rule of thumb is 15–20% of the build cost every year, just to keep the app functioning — bug fixes, library updates, breakages. Treat it as a starting figure, not a law: software-maintenance research shows upkeep can consume a far larger share of a product's lifecycle cost as it ages and grows in complexity. Nigerian studios often quote maintenance at roughly ₦20,000 to ₦300,000 per month depending on the app.
- Operating-system updates. Apple and Google ship a major OS version every year. An app left untouched may fail new OS requirements, break on newer devices, or eventually face store-compliance issues.
- Store presence. The Apple Developer Program currently costs about $99 per year, recurring; a Google Play developer account is about $25, one-time. Small, but dollar-denominated and easy to forget.
- Backend and hosting. Servers, database, notifications — a monthly cost that grows with your users.
- Iteration. Your first version is a hypothesis. The version that actually works for customers comes from the changes you make after launch.
A ₦900,000 app with no maintenance plan, no real backend, and no clear owner of the code is not cheaper. It is unfinished — and you discover that the first time it breaks and the person who built it has moved on.
Where a cheap quote quietly costs you
The failure modes we see most often:
- The hostage situation: you do not own the source code, so you cannot move to another developer without paying to rebuild. Real ownership means administrative access to the version-control repository, such as GitHub, and complete documentation — not a zipped folder of code on a flash drive.
- The house of cards: there was no real backend — the app was a demo that falls over on live data. A real backend means scalable server infrastructure, a managed or headless setup, or a Backend-as-a-Service platform such as Supabase, rather than a hard-coded shortcut that buckles the moment traffic is real.
- Half your market: it is one platform only, so you pay a second time later to reach the other half of your customers.
- The dead end: the freelancer becomes unreachable, and no one else can read the undocumented code.
- The translation tax: nothing was documented, so the next developer charges you just to understand it before fixing anything.
The Nigeria-specific realities
Most serious development tooling and the app stores themselves are dollar-denominated, so a naira quote shields you from exchange-rate exposure only until renewal. Local talent is genuinely strong, but it is mobile — retention and handover matter, which is why code ownership and documentation belong in the contract, in writing. And your users sit on a wide range of low-to-mid Android devices on metered data, so app size and performance are business concerns, not engineering vanity — another reason the native-versus-cross-platform question deserves a real answer rather than a default.
The questions a good quote should answer
Before you sign anything, send these back to your developer:
- Which platforms, native or cross-platform — and why is that the right call for my app?
- Is there a real backend, and what will it cost per month to run?
- Do I own the source code and all accounts outright — with admin access to the code repository and full documentation, not just a zipped folder? Get it in writing.
- What is the post-launch plan, and what is the monthly maintenance cost?
- What recurring third-party costs will I carry — stores, hosting, SMS, maps, notifications?
- Who maintains the app if you become unavailable?
A developer who can answer these cleanly is already worth more than one who cannot.
What to do now
The cheapest quote and the most expensive quote are both easy to choose for the wrong reason. The right number is the one attached to the fullest, most honest set of assumptions — the cost of owning a working app for three years, not the price of handing over a build. Ask for that number. The cheap quote only wins if it stays cheap after launch.
Before you accept the quote, ask what it will cost to own the app for three years. If you want a second opinion, Inventrium can review the quote with you: see how we approach mobile app development or book a free 30-minute conversation.
