SaaS Development For Startups, SMEs, MNCs and Product Founders.
SaaS development is the process of building a cloud-hosted software product that multiple organisations access via subscription. A SaaS platform uses multi-tenant architecture: one application serves many client organisations, each with their own isolated data, users and settings. Unlike a custom web application built for internal use, a SaaS product is a revenue-generating software business built to scale.
UNO is a SaaS development company in Malaysia that builds custom SaaS platforms from MVP to enterprise scale. We design the architecture, build the multi-tenant backend, handle subscription billing, onboarding and integrations, and support the platform post-launch. With 21+ years of experience and 900+ projects delivered, we help founders and businesses turn a product idea into a live, paying SaaS.
Build a SaaS Platform That Other Businesses Pay to Use
Most businesses have domain expertise that could be productised: a workflow they've mastered, a system they've built internally, a process that others in their industry still do manually. A SaaS platform turns that expertise into recurring software revenue.
UNO helps you define the product, design the architecture, build the application, set up subscription billing and launch to your first paying customers. We plan for multi-tenancy from day one so your platform can scale without expensive rewrites later.
Custom SaaS Development Services
We design and develop SaaS platforms for B2B software products, subscription-based portals, industry-specific tools, multi-tenant business systems and cloud-hosted applications.
Multi-Tenant SaaS Architecture
Purpose-built multi-tenant platforms where each client organisation has isolated data, their own user accounts and customisable settings. All on shared infrastructure.
Subscription Billing & Plan Management
Recurring billing, free trials, usage-based pricing, plan upgrades and downgrades, invoice generation and payment gateway integration for SaaS subscription models.
Customer Onboarding & Self-Service
Guided onboarding flows, self-registration, workspace setup, account invitations and in-app tutorials that let new tenants start using your SaaS without manual intervention.

Marketplace & Platform SaaS
Two-sided marketplace platforms, booking engines and aggregator tools where suppliers and buyers interact on a managed subscription or transaction-fee model.
SaaS vs Custom Web Application: Key Differences
Both are web-based software, but the purpose, architecture and business model are different. Understanding the distinction helps you choose the right approach for your project.
| Criteria | Custom Web Application | SaaS Platform |
|---|---|---|
| Who uses it | One organisation (internal team or customers) | Multiple organisations (tenants) on subscription |
| Architecture | Single-tenant (one database per client) | Multi-tenant (shared infrastructure, isolated data) |
| Revenue model | One-time build cost; internal tool | Monthly or annual subscription per tenant |
| User management | Users within one organisation | Multiple organisations, each with their own users |
| Billing features | Not required | Subscription plans, trials, invoices, upgrades |
| Onboarding | Deployed once for the client | Self-serve registration and tenant setup |
| Malaysia cost range | RM 30,000 – RM 120,000+ | RM 50,000 – RM 200,000+ |
| Build timeline | 3 – 12 months | 4 – 12 months (MVP to full platform) |

Why Build Your SaaS With UNO?
SaaS development requires more than coding. It requires product thinking: defining the tenant model, pricing structure, onboarding journey and data isolation strategy before a single line of code is written. UNO brings both technical depth and product experience to help you build something that works at launch and scales as you grow.
Multi-Tenancy from Day One
We architect your platform for multi-tenancy from the start, so you avoid the expensive rework of retrofitting it later.
Full-Stack In-House Team
Strategy, UI/UX design, backend, frontend, DevOps, testing and support. All handled by UNO's in-house Malaysian team.
MVP-First Approach
We help you launch a focused MVP quickly, gather real user feedback, then expand features based on what your customers actually need.
Post-Launch Growth Support
After launch, UNO stays on as your development partner, adding features, scaling infrastructure and integrating new systems as your user base grows.
Our SaaS Development Process
Every SaaS project starts with product definition, not code. We map the tenant model, user journeys and feature scope before design begins, so the architecture supports your business model and not just the MVP.
Product Definition & Tenant Modelling
We define your SaaS product: who the tenants are, what each user role can do, how data is isolated, which features are in the MVP, and how the subscription model works. This becomes the blueprint for everything that follows.
UI/UX Design for SaaS
We design user interfaces for each user role: tenant admin, end users and super admin. Onboarding flows, subscription upgrade prompts, empty states and in-app navigation are designed to reduce friction and improve activation.
Multi-Tenant Backend Development
We build the multi-tenant architecture with data isolation per tenant, role-based access control, subscription plan enforcement, API development and cloud database design. Security and scalability are built in from the start.
Billing, Onboarding & Integrations
We integrate subscription billing (recurring payments, trials, plan management), build tenant self-registration and onboarding flows, and connect your SaaS with the third-party tools your customers already use.
Testing, Cloud Deployment & Launch
We test across all user roles and tenant scenarios before deploying to cloud infrastructure. Go-live includes performance testing, security review, DNS setup and a staged rollout plan to your first customers.
Post-Launch Support & Feature Iteration
We stay on after launch, monitoring the platform, resolving issues, scaling infrastructure as users grow, and building the next iteration of features based on real customer feedback and usage data.
Frequently Asked Questions
What is SaaS development?
SaaS development is the process of building a cloud-hosted software product that users access via a web browser on a subscription basis. SaaS platforms use multi-tenant architecture, where one application serves multiple client organisations, each with isolated data and configurable settings. The SaaS vendor manages infrastructure, security and updates; customers simply log in and use the product.
How much does SaaS development cost in Malaysia?
Custom SaaS development in Malaysia starts from RM 50,000 for a focused MVP and ranges to RM 200,000 or more for enterprise multi-tenant platforms. Cost depends on the number of user roles, tenant isolation complexity, subscription billing features, integrations and expected concurrent users. See UNO's indicative pricing.
How long does it take to build a SaaS platform?
A SaaS MVP typically takes 3 to 5 months. A full-featured platform with subscription billing, onboarding flows, super-admin controls and multiple integrations takes 6 to 12 months. Timeline depends on feature scope, integration complexity and how many user roles must be supported across tenants.
What is multi-tenant architecture?
Multi-tenant means a single SaaS application serves multiple customer organisations from one codebase and infrastructure, while keeping each organisation's data completely isolated. Each tenant can have their own users, settings and branding. This makes SaaS platforms cost-efficient to run and easy to update across all customers at once, rather than maintaining a separate deployment per client.
Can UNO build a SaaS MVP for my startup?
Yes. UNO works with founders and product owners to scope, design and build SaaS MVPs that can be launched quickly and iterated on after launch. We help you prioritise the right features, design for activation, and build an architecture that supports growth so you're not rewriting the platform when your first 50 customers sign up.
What is the difference between a SaaS and a custom web app?
A custom web application is built for one organisation to manage its internal processes. A SaaS platform is a software product sold to many organisations on a subscription basis. SaaS requires multi-tenancy, subscription billing, self-service onboarding and a super-admin layer for the SaaS operator. None of which are typically needed in a single-tenant custom web app. See our custom web application page for comparison.
