Accurate Project Cost Estimation

"How much will this cost?" is the first question almost every founder asks, and the honest answer is always "it depends on scope" — but that's not useful on its own. This guide breaks down what actually drives software project costs, gives realistic ranges for websites, apps, and custom software, and covers what changes when you're building in Nigeria specifically versus hiring internationally.

The Short Answer: Typical Ranges

These are industry-wide ranges, not fixed prices — the same "mobile app" brief can land anywhere in that range depending on exactly what it needs to do. The rest of this guide explains why.

What Actually Drives Cost

• Number of unique screens/pages and user flows — a 5-screen app costs a fraction of a 40-screen app, roughly in proportion to the design and engineering work involved.
• Backend complexity — whether you need user accounts, a database, real-time features, or just static content changes the engineering effort substantially.
• Integrations — payment gateways, SMS/email providers, maps, third-party APIs — each one adds integration, testing, and error-handling work.
• Design ambition — highly custom, animated, brand-specific design takes longer than building within a proven, simpler design system.
• Where you hire — rates vary significantly by region and by whether you hire a freelancer, an agency, or an in-house team.

Building in Nigeria: What's Different

Business Gates is based in Ajah, Lagos State, and builds for clients across Nigeria and internationally. A few things are worth knowing if you're budgeting for a project built by a Nigeria-based team:

• Nigerian development rates are generally more competitive than US/UK/EU agency rates for comparable quality, which is one reason many international founders outsource to Nigerian and broader African development teams.
• Payment integration for a Nigeria-facing product typically means Paystack or Flutterwave rather than (or alongside) Stripe, since these are built around Nigerian bank rails and support Naira natively.
• If your product needs to serve both Nigerian and international customers, plan for dual payment processor support from the start — retrofitting a second processor later is more work than including it in the original scope.

How to Get an Accurate Estimate (Not Just a Guess)

• Write down every screen or page you expect the product to have, even roughly — vague scope produces vague estimates.
• List every third-party service you expect to integrate (payments, maps, notifications, analytics).
• Decide upfront whether you're building an MVP (core functionality only) or a fully-featured v1 — these can differ in cost by 3–5x for the same underlying idea.
• Get quotes from more than one team, and be wary of quotes that are dramatically lower than others for the same written scope — it usually means something in the scope was assumed away.
