Custom software development in Lagos — built right the first time.
Gsoft Interactive Systems is a Lagos-based custom software development company building enterprise web platforms, multi-tenant SaaS, internal tools, and APIs for Nigerian fintech, government, and high-growth businesses since 2017.
What we mean by "custom software development"
Every Nigerian business hits a point where off-the-shelf software stops fitting. Excel can only model so much; SaaS subscriptions add up; vendor roadmaps don't include your edge cases. Custom software is the answer when your business logic is the competitive advantage — and you need a system that captures it precisely, owns the data, and grows with you.
We build that software. From the first whiteboard sketch through architecture, build, launch, and 24/7 support — handled by one team that stays with you.
Our software development services
Enterprise web platforms
Multi-user, role-based platforms with serious workflow logic — claims processing, loan origination, healthcare records, supply chain. Built on Laravel or Node.js with audit trails, encryption, and compliance baked in from day one.
Multi-tenant SaaS products
If you're building a product, not just a tool, we know multi-tenancy. Row-level isolation, per-tenant branding, billing integration, and the architectural patterns that prevent one customer's data ever touching another's. See Growzen and Every27.
API & backend services
RESTful and GraphQL APIs that other teams (yours or third-party) consume. OpenAPI documentation, versioning, rate limiting, authentication standards (OAuth 2.0, Sanctum, JWT), and deployment pipelines with full observability.
Internal tools & admin platforms
The dashboards and ops tools that nobody sees but everybody depends on. Filament, Retool-style internal apps, custom-built admin panels — the kind of software that quietly runs your operations.
DevOps, deployment & cloud
CI/CD on GitHub Actions, infrastructure on AWS / DigitalOcean / Hetzner / cPanel as the project demands, monitoring with Sentry and uptime checks, automated backups, and disaster recovery playbooks. If we build it, we keep it running.
System integrations
Payment gateways (Paystack, Flutterwave, Stripe), KYC vendors (Smile ID, Verify Me, Premblee), SMS & OTP (Termii), accounting (QuickBooks, Sage, Zoho), and any internal legacy system worth integrating to.
Our development process
1. Discovery & scoping
A focused workshop — usually 1 week — where we map your goals, constraints, and the business logic that matters. You leave with a written scope, fixed-price proposal, and architecture sketch.
2. Design & architecture
Wireframes through high-fidelity UI in Figma, plus architecture diagrams covering data, services, integrations, and deployment. Sign-off before any code is written.
3. Build in milestones
Weekly demos, fortnightly milestones, payment tied to deliverables. You see progress every week and can redirect within the agreed scope.
4. Launch
Staged rollout: staging, UAT, production. We handle DNS, SSL, CDN, and all the launch-week details. Including the post-launch firefighting nobody likes to talk about.
5. Maintain
Optional retainer for ongoing maintenance — security updates, feature additions, monitoring, and 24/7 incident response. Most of our clients stay on retainer because the team that built it is the team that knows it best.

Frequently asked questions
How much does custom software development cost in Nigeria?
Scope-dependent. A typical small-business MVP starts from ₦4–8M; mid-size SaaS platforms from ₦15M; enterprise builds from ₦30M+. We give a fixed-price proposal after the discovery week.
What technology stack does Gsoft use?
We default to Laravel and Node.js on the backend, Vue/React/Inertia.js or Next.js on the frontend, Flutter for mobile, and PostgreSQL or MySQL for data. We pick the stack to fit the problem.
Who owns the code?
You do. On full payment, we transfer the code to a repository you own and remove our access if you want us to. (Most clients don't — we end up maintaining what we built.)
Do you sign NDAs?
Always — at first contact if needed. We also handle data protection, NDPR compliance, and any sector-specific compliance you require.
