What You Get With Our SaaS Development Services

🏗️

How do you architect a SaaS product that scales to thousands of customers?

We use multi-tenant architecture with logical or physical tenant isolation, stateless services, horizontal scaling, and a shared-nothing data model. Load testing is performed before launch to validate the platform against your projected customer growth curve.

💳

How is subscription billing and plan management handled?

Stripe or Chargebee integration manages subscription plans, trial periods, metered usage billing, plan upgrades/downgrades, proration, invoicing, and failed payment recovery. Customers manage their own subscriptions from a self-service billing portal.

🔐

How do you prevent one tenant's data from leaking to another?

We implement row-level security in PostgreSQL, scoped API keys, tenant-aware middleware that injects tenantId into every database query, and automated test suites that specifically verify cross-tenant data isolation after every deployment.

🔗

Can enterprise customers use their own SSO to log in?

Yes — SAML 2.0 and OAuth 2.0 integration allows enterprise tenants to use their own identity provider (Okta, Azure AD, Google Workspace) for single sign-on. Provisioning and deprovisioning via SCIM is also available for large enterprise customers.

📊

What analytics can we see about how customers use the SaaS product?

A built-in product analytics layer tracks feature adoption, session data, conversion funnels, and churn indicators per tenant. This data feeds into a founder dashboard showing which features drive retention and which are ignored — essential for product prioritisation decisions.

🌏

Can the SaaS product be sold to international customers, not just Australian?

Yes — we build internationalisation (i18n) and localisation (l10n) support from day one, with multi-currency billing, locale-aware date/number formatting, and timezone handling. Customers outside Australia receive billing in their own currency with localised tax treatment.

🔒

What security certifications can the SaaS product achieve?

We design SaaS products to meet SOC 2 Type II and ISO 27001 requirements — implementing the controls required for certification during development rather than retroactively. We also support Australian Privacy Act compliance and, for healthcare SaaS, HIPAA and My Health Record integration standards.

📈

How do we handle database performance as the number of tenants grows?

Database partitioning, read replicas, connection pooling (PgBouncer), query optimisation, and Redis caching are implemented proactively based on your projected growth. We set performance budgets and monitor query times as tenant count scales so degradation is caught before customers notice.

Our SaaS Development Process

01

Product Strategy & Technical Blueprint

We workshop your target customer, core use case, pricing model, and competitive positioning — then translate that into a technical architecture blueprint covering multi-tenancy, billing, and integration requirements before writing code.

02

MVP Scoping & Fixed-Price Proposal

We identify the minimum feature set needed to validate your market and deliver a fixed-price proposal with a launch timeline. MVP scope is deliberately constrained — we help you avoid over-building before you have paying customers.

03

Agile Development & Beta Programme

Two-week sprints deliver working SaaS features from week three. A closed beta with 5–10 design partners runs during the final sprints — real user feedback shapes the final product before public launch.

04

Launch, Hypercare & Growth Development

Public launch is managed with monitoring, alerting, and on-call support for the first two weeks. Post-launch, we move into a continuous feature delivery cadence prioritised by your product analytics and customer feedback.

SaaS Development FAQs

Common questions about our saas development services.

Ask Us Anything →
How much does SaaS development cost in Australia?
SaaS MVP development in Australia starts from AUD $40,000 for a focused single-use-case product with subscription billing and user management. A full-featured multi-tenant SaaS with enterprise SSO, advanced analytics, and complex business logic typically ranges from AUD $100,000 to $300,000+. OpenMalo provides a fixed-price MVP proposal after a free discovery session.
How long does it take to build and launch a SaaS product?
A well-scoped SaaS MVP takes 10–16 weeks from kick-off to public launch. A comprehensive enterprise SaaS with SSO, complex integrations, and advanced reporting takes 6–12 months. We use design partners during the beta phase to validate the product before full public launch.
What is multi-tenant architecture and why does my SaaS need it?
Multi-tenancy means all your customers share the same application infrastructure, but each customer's data is completely isolated from others. This allows you to scale efficiently — adding customers doesn't require deploying separate infrastructure for each one. It's the standard architecture for commercially successful SaaS businesses, enabling economies of scale in hosting and maintenance.
How do you handle different subscription plans and pricing tiers?
Pricing logic is defined in your Stripe or Chargebee configuration and mirrored in the application's feature flag system. Customers on different plans see different features, usage limits, and UI elements. Upgrades and downgrades are handled instantly via Stripe's plan migration API with correct proration calculations.
Can the SaaS product integrate with tools our enterprise customers already use?
Yes — enterprise SaaS products commonly need to integrate with Salesforce, Microsoft 365, Google Workspace, Slack, Jira, and industry-specific tools. We build a public API and webhook system as standard so enterprise customers can connect your SaaS to their own internal systems without requiring custom development from your side.
How do you protect the SaaS from security vulnerabilities?
We implement OWASP Top 10 mitigations, automated SAST scanning in CI/CD, dependency vulnerability monitoring, penetration testing before launch, and rate limiting on all public endpoints. Multi-tenant data isolation is verified by automated test suites. For enterprise SaaS, we produce SOC 2 and ISO 27001 documentation.
Who owns the SaaS product code after development?
You own 100% of the source code and intellectual property. Upon project completion we transfer the complete codebase, infrastructure scripts, CI/CD configuration, and all documentation. OpenMalo retains no licensing rights and you are free to have any team maintain or extend the product.
What happens if the SaaS product needs to scale rapidly after launch?
We design for scale from the beginning: stateless application services, database read replicas, Redis caching, CDN-delivered assets, and Kubernetes-based auto-scaling. If you experience a rapid growth event, our DevOps team can respond within hours to provision additional capacity and resolve any bottlenecks.
Can you help us design the SaaS pricing model before development starts?
Yes — pricing strategy is part of our product strategy workshop. We analyse your target market, competitive pricing benchmarks, and unit economics to recommend a pricing model (per seat, per usage, per feature tier, or hybrid). Getting pricing right before building subscription logic saves significant rework later.
Do you provide ongoing development after the SaaS launches?
Yes — we offer post-launch SaaS development retainers from AUD $5,000/month. These include a dedicated feature development team, infrastructure management, security monitoring, and product analytics review. Most SaaS founders retain us for 12–24 months post-launch as the product grows and evolves.
