SaaS Application Development

Software products built
for recurring growth
from day one

SaaS needs more than a codebase. It needs a strong product foundation — accounts, onboarding, subscription billing, and the internal workflows that keep the platform usable as your customer base scales from ten to ten thousand.

What We Build

SaaS products across
every vertical

A SaaS product is more than a web application with a subscription attached. It requires careful product thinking around user accounts, onboarding flows, recurring billing, workspace management, and the operational systems that keep the business running as it scales. Here is what we build most often.

B2B SaaS Platforms

Business-to-business tools that teams subscribe to monthly. We build with workspace isolation, team management, role-based access, and billing logic designed for organisational accounts from the start.

WorkspacesTeam RolesOrg BillingAdmin Panel

Vertical SaaS

Industry-specific platforms built for a single profession — logistics, healthcare, legal, recruitment, or education. Domain-specific workflows, compliance needs, and reporting requirements are built in from day one.

Custom WorkflowsReportingIntegrationsCompliance

API-First SaaS Products

Products where the API is the core deliverable — developer platforms, data services, or integrations. Built with versioning, API key management, usage tracking, rate limiting, and documentation from day one.

REST APIAPI KeysUsage LimitsPostman Docs

Subscription Billing Platforms

Products where monetisation is the core architecture. Plan tiers, feature gating, trial periods, upgrade/downgrade flows, invoice generation, and renewal management structured cleanly from the beginning.

Analytics & Intelligence Platforms

Data-driven SaaS tools that ingest, process, and surface insights. We structure the data pipeline, dashboards, export functionality, and scheduled reporting so users can act on what the platform shows them.

MVP to Production SaaS

Early-stage products that need to launch quickly without sacrificing the foundations that matter. We help founders move from validated idea to working SaaS in weeks, with the architecture in place to scale when traction arrives.

How We Architect It

Five layers every
SaaS product must get right

Most SaaS products fail not because of the core feature, but because the surrounding foundations — onboarding, billing, permissions, admin visibility — were added as afterthoughts. We design these in from the start, as first-class parts of the product architecture.

Onboarding Layer
Sign-up · First-run flows · Activation triggers

The first ten minutes of a user's experience determine whether they ever return. We design and build sign-up flows, email verification, guided first-run sequences, and activation checkpoints that move new users from registration to the moment they first experience your product's core value.

Email VerificationWelcome SequencesProgress ChecklistsFeature ToursActivation Events
Billing & Subscription Layer
Plans · Feature gates · Renewals · Invoices

Subscription logic is more complex than it appears. We build plan tiers with feature-level access control, trial period management, upgrade and downgrade flows, proration handling, failed payment recovery, invoice generation, and webhook processing — so your billing infrastructure is production-grade from launch.

Paystack / StripePlan TiersFeature GatingTrial ManagementInvoice PDFsWebhooks
Multi-tenancy & Accounts Layer
Workspaces · Teams · Roles · Permissions

For B2B SaaS, the account model — how organisations, teams, and individual users relate to each other — is one of the most important architectural decisions made early. We implement workspace isolation, invitations, team roles, and granular permission policies that scale cleanly as your customer accounts grow in size and complexity.

Workspace IsolationTeam InvitationsRBACSpatie PermissionsSSO-Ready
Admin & Operations Layer
Customer management · Visibility · Support tools

Your team needs to support customers, manage subscriptions, investigate issues, and track product health without needing a developer for every query. We build a Filament admin panel with full customer visibility, subscription overrides, activity logs, and the operational tools your team will actually use every day.

Filament 5 AdminCustomer ProfilesActivity LogsSubscription OverridesImpersonation
Infrastructure & Reliability Layer
Queues · Monitoring · CI/CD · Zero-downtime

A SaaS product is expected to be available every hour of every day. We deploy with zero-downtime release pipelines, configure background queue workers for emails and processing tasks, set up uptime monitoring and error tracking, and establish the infrastructure baseline so your platform behaves reliably as usage grows.

How We Work

Our SaaS delivery process

Building a SaaS product is not the same as building a website or a simple web application. The product decisions made in the first two weeks — account structure, billing model, permission design — will define what is easy or expensive to change for the next several years. Our process is built around making those decisions correctly before writing a line of code.

Five phases.
Zero guesswork.

Every milestone is documented and agreed before we begin. You always know what is being built, what it will cost, and when it will be ready.

01
Product Discovery & Scoping
Week 1–2

SaaS discovery goes deeper than a standard application brief. We map your target customer, their workflow, and the problem your product solves. From there we define your user types, subscription model, feature set by tier, onboarding sequence, and the admin workflows your team will need to operate the product.

The output is a Product Specification — a written document covering the account model, billing structure, feature list by plan, user journey maps, and technical constraints. This spec governs the entire build and makes scope changes explicit and transparent.

Product SpecAccount ModelBilling StructureUser Journey MapsFeature Matrix
02
Architecture & Data Modelling
Week 2–3

Before any code is written, we design the database schema, API structure, authentication model, permission matrix, subscription logic, and integration architecture. For SaaS products in particular, the data model is the most load-bearing decision in the entire project — a flawed schema creates cascading problems that become exponentially harder to fix after launch.

We review the architecture with you in a dedicated session and iterate until every relationship, constraint, and business rule is correctly represented. Only then do we begin development.

ER DiagramPermission MatrixBilling ModelAPI SpecIntegration Map
03
UI/UX Design in Figma
Week 3–4

High-fidelity designs are produced for every key screen — the marketing site, onboarding flow, user dashboard, settings, billing portal, and admin panel. For SaaS products, we pay particular attention to the onboarding experience: the design of those first three screens determines your activation rate more than any other product decision.

Interactive Figma prototypes let you experience the product flows before a component is built. Design sign-off gates the development phase — we do not build what has not been approved.

SaaS Development
Week 4–14 (scope-dependent)

We build in two-week sprints on a private staging environment, with a demo at the end of every sprint. Development proceeds in layers: authentication and account model first, then billing infrastructure, then core product features, then admin panel, and finally onboarding and notification systems.

Payment integrations are built and tested in sandbox before any production billing is enabled. Every sprint is demoed before work on the next begins — you have continuous visibility into what is being built and how it behaves.

05
Launch, Handover & Post-launch Support
Week 14–16

Production deployment is zero-downtime via GitHub Actions CI/CD. We configure the server environment, queue workers, scheduled tasks, monitoring, and alerting before the first user lands. You receive the full source code on GitHub, a technical documentation pack, and a 90-day post-launch support window covering bug fixes, performance monitoring, and minor feature adjustments as you get real users using the product.

What You Get

Everything included
in every SaaS build

These are not optional extras. They are standard deliverables on every SaaS project we take on. We believe the foundations of a serious software product should always be complete — regardless of project budget.

Multi-tenant Account Architecture

Workspaces, team accounts, individual seats, and organisation-level billing are designed as first-class entities — not bolted on after the first paying customer asks for them.

Activation-Focused Onboarding

Sign-up, email verification, first-run guidance, and progress checklists designed to move new users from registration to the core value of your product before they lose interest.

Subscription Billing Engine

Plan tiers, feature gates, trial periods, upgrade/downgrade flows, invoice generation, and failed payment recovery — built to handle real subscription behaviour at scale.

Role-Based Access Control

Granular permission policies using Spatie Permissions — defining what each user role can see, create, edit, and delete across every part of the application. Unit-tested from day one.

Filament Admin Panel

A fully-featured admin interface for your team to manage customers, subscriptions, feature overrides, support queries, and product operations — without needing developer involvement for daily tasks.

REST API with Documentation

Every SaaS product includes a versioned REST API with consistent JSON responses, authentication via Laravel Sanctum, rate limiting, and Postman documentation delivered on handover.

Background Jobs & Notification System

Queued jobs for emails, renewal processing, report generation, and integrations — plus a full notification system for in-app, email, and push messages tied to product events.

CI/CD Pipeline & Zero-Downtime Deployment

Automated testing and zero-downtime deployment to production via GitHub Actions. Your SaaS platform is never taken offline for a release — updates happen invisibly while users are active.

Client Reviews

What clients say about
our SaaS work

★★★★★

"The onboarding flow alone was worth the engagement. We saw a 60% increase in activation rate compared to our previous product. i2Medier understood that the first three minutes in a SaaS product are everything — and built accordingly."

Founder
B2B SaaS Platform
★★★★★

"We had tried two other agencies before i2Medier. Neither understood that subscription billing is not just Stripe — it is a whole set of business rules around upgrades, dunning, proration, and reporting. They got it right from the start."

CTO
Vertical SaaS Product
★★★★★

"The Filament admin panel means our support team can manage customers, override subscriptions, and investigate issues without a developer. That alone has saved us hours every week and made our customer response time far faster."

A SaaS product has recurring business complexity that a standard application does not: subscription billing with trials and renewals, multi-tenant account isolation, feature gating per plan, onboarding flows designed for activation, and the admin tools your team needs to support customers at scale. These are not add-ons — they are core to the product. Building them properly from the start is what separates a product that scales from one that needs a full rewrite at 500 customers.
It depends on your product model. If your customers are organisations with multiple users sharing data within a workspace — yes, you need multi-tenancy. If your product is individual-user focused with no team collaboration, a simpler account model may be sufficient. We diagnose this during discovery and recommend the right architecture for your specific product, rather than applying a default multi-tenant template to everything.
We integrate Paystack for Nigerian naira subscriptions and Stripe for international billing. Both are implemented with full subscription support — recurring charges, plan upgrades, downgrades, trial periods, failed payment recovery (dunning), and invoice generation. We also integrate Flutterwave when the payment mix requires it. All integrations are tested thoroughly in sandbox before any production billing is enabled.
MVP SaaS products with core billing and onboarding typically take 8–10 weeks from design sign-off. Full-featured platforms with multi-tenancy, team accounts, feature gating, and a complete admin panel range from 12–16 weeks. Enterprise-grade SaaS with complex integrations and high-traffic requirements can take 20+ weeks. We provide a detailed, milestone-by-milestone timeline during discovery — you know exactly what is happening and when before any commitment is made.
Yes — but we will first conduct a codebase audit to understand the current quality, architecture decisions, and technical debt. For some projects, building on the existing code is the right call. For others, the debt is significant enough that starting fresh is faster and cheaper in the medium term. We will give you an honest assessment with a clear recommendation and cost comparison before any work begins.
SaaS MVP products start from ₦1.2 million. Full-featured platforms with multi-tenancy, subscription billing, and a complete admin panel typically range from ₦2M to ₦5M. Enterprise SaaS is quoted based on scope. All projects receive a written, itemised proposal after a free discovery session — you know exactly what you are paying for before any commitment is made. There are no hidden costs and no scope changes that are not agreed in writing first.
