SaaS Platforms & Internal Systems

Generic Software Is Costing You More Than You Think

You're paying S$200–S$500 a month for project management software that has features your team will never use and doesn't have the workflow automation that would actually save them an hour a day. You've got three different tools that each handle one part of a process that should be one seamless operation. You're paying subscription fees every month for the privilege of working around software that wasn't built for how you actually work.

At some point, the cost of fighting generic software exceeds the cost of building something that fits. That crossover happens earlier than most Singapore SMEs expect — and when it does, the ROI on a custom SaaS platform or internal system is often compelling within 18–24 months.

At NICKTUNG, we build SaaS platforms for companies bringing a product to market and internal systems for companies that need operational software designed around their actual workflows — not a category.

Two Very Different Products, One Discipline

SaaS platforms are customer-facing products your business sells to others as subscriptions. They need multi-tenant architecture, subscription billing, role-based access, onboarding flows, usage tracking, and the scalability to serve many customers without performance degrading as the user base grows.

Internal systems are operational software built for your team. They don't need to impress customers — they need to be fast, precise, and exactly fitted to the workflow they serve. A field operations app for your service team. A procurement approval system. An ops dashboard that aggregates data from four different sources into one view. A client portal with the exact functionality your account management team needs and nothing they don't.

We build both, and we bring the same architectural rigour to each: data model designed for the use case, performance built in from the start, security appropriate to the data involved.

What Multi-Tenant SaaS Architecture Actually Requires

Building a SaaS platform that can grow from 10 customers to 1,000 without a rebuild requires getting multi-tenancy right from the start. The key decisions:

• Data isolation model — separate schemas per tenant, shared schema with tenant ID, or separate databases. Each has different cost, security, and scalability profiles.
• Row-level security — ensuring that queries at the database level, not just the application level, are scoped to the correct tenant. Critical for compliance and security.
• Subscription and billing integration — connecting your application to Stripe or another billing provider, handling subscription state changes, trial expirations, and failed payments gracefully
• Feature flagging — rolling out features to subsets of customers, implementing plan-based feature gating, and testing in production without affecting all customers
• Usage metering — tracking what each customer is consuming so you can enforce limits, optimise your pricing, and identify high-value customers

Getting these decisions right early prevents expensive rewrites later. We've seen SaaS platforms need complete data layer rebuilds because the original tenant isolation strategy couldn't scale — work that costs more than the original build.

Build vs. Buy: The Honest Framework

We don't recommend custom builds when off-the-shelf software is genuinely the right answer. Here's the framework we use:

• Build when your workflow is genuinely differentiated and that differentiation is a competitive advantage; when no off-the-shelf solution fits without extensive customisation; when the total cost of licensing and workarounds over 3 years exceeds the build cost
• Buy when the workflow is standard and the software category is mature; when configuration can get you 90% of the way there; when the cost of custom development can't be justified by the productivity gain

When we do recommend building, we scope conservatively — building exactly what the workflow requires and no more. Over-featured internal tools are almost as bad as under-featured generic ones.

EDG Grants for SaaS and Internal System Development

Custom software development that builds new business capabilities or creates a new digital product qualifies for Singapore's Enterprise Development Grant (EDG), which co-funds up to 50% of costs.

Projects in this category typically range from S$40,000 to S$200,000. NICKTUNG helps structure the project scope and EDG application to maximise the funding available while delivering the technical outcome you need.

What to Expect After We Build It

Software doesn't get maintained by magic. NICKTUNG delivers documentation, infrastructure runbooks, and the codebase in a state your team can own. We offer ongoing maintenance and enhancement retainers for clients who want continued support — but we don't make you dependent on us. The product is yours.

Frequently Asked Questions

How long does it take to build a custom internal system?

Simple internal tools (10–20 screens, well-defined workflows) typically take 6–10 weeks. More complex systems with integrations, reporting, and role-based access take 3–5 months. SaaS platforms with multi-tenant architecture and billing integration typically take 4–6 months for the initial product. We scope accurately before we start.

What happens if our requirements change mid-build?

We work in 2-week sprints with review checkpoints, so you see working software every two weeks and can redirect priorities as your understanding develops. We manage scope changes transparently — new work is estimated, communicated, and approved before it's started. No surprise invoices.

We're worried about vendor lock-in. What happens if we ever need to move away from NICKTUNG?

Everything we build uses standard open-source technology stacks. The codebase is yours, documented, and deployable by any competent development team. We deliberately avoid proprietary deployment platforms or infrastructure that would create dependency. You can take the code and run it anywhere.
