SaaS Development

Custom software built for your exact workflow

Existing software gets you 80% of the way. When that remaining 20% is core to how your business operates and no existing product covers it, we build the software that does.

The problem

No existing product does exactly what your business needs

You have looked at the options. There is always a gap. A workflow your team has to do manually because no integration covers it, a report that requires three exports and a spreadsheet because no single tool generates it, or a client facing feature that every SaaS product treats as a premium extra.

Custom SaaS development is not always the answer. We will tell you when an existing product or integration covers your needs better. But when the gap is real, we build software that fits your process exactly, scales with your business, and does not require workarounds to use.

What You Get

Design, development, and deployment. Complete.

Every project includes technical design, UI/UX, development, QA, and production deployment.

SaaS Platform Design

Multi-tenant SaaS products with proper data isolation per organisation, subscription billing via Stripe, role based access control, and a foundation that scales without rebuilding from scratch. We design the full system before writing code.

Admin Dashboards and Internal Tools

Operations dashboards, CRM replacements, inventory management systems, HR portals, and reporting platforms built for internal teams. Often the highest ROI digital investment a growing service business can make.

API Development

REST and GraphQL APIs with versioning, authentication, rate limiting, webhook support, and OpenAPI documentation. Every endpoint documented with a sandbox environment for integration partners.

Cloud Hosting and Deployment

Vercel or AWS deployment configured for your traffic profile. CI/CD pipelines via GitHub Actions, staging and production environments, 99.9% uptime SLA, automated backups, and zero downtime deployments from day one.

Security and Compliance

HTTPS enforcement, input validation, SQL injection protection via parameterised queries, CSRF protection, rate limiting, role based access control, and OWASP Top 10 compliance. Security is built in from the data model, not added later.

How We Work

From brief to production in six steps

A defined process that keeps scope, budget, and timelines under control across the full build.

01

Requirements and Scoping

Define the exact feature set, user roles, data model, and third-party integrations. We write a detailed specification and provide a fixed-price quote before any code is written.

02

Technical Design

Database schema, API structure, authentication model, third-party integrations, and deployment planning documented before development starts. You see the full technical plan and approve it.

03

UI/UX Design

Figma wireframes for every screen and user flow, then high-fidelity mockups. Design is approved before development begins. This prevents expensive mid-build rewrites when requirements surface in the build phase.

04

Development in Agile Sprints

Two week sprints with a working demo at the end of each. TypeScript strict mode throughout, peer code reviews on every pull request, and automated tests for critical paths.

05

QA and Security Testing

Load testing under realistic traffic conditions, OWASP Top 10 review, penetration testing on authentication and data access paths, and a full staging environment review before production deployment.

06

Deployment and Handover

Production deployment with monitoring configured for uptime, errors, and performance. Full technical documentation, deployment runbooks, and a knowledge transfer session for your team.

Technology Stack

Production-proven tools, no experiments

Every tool in our stack has been used in multiple production deployments and is well documented for future developers.

How we approach SaaS builds differently

Scope defined before a single line of code

We write a detailed specification and provide a fixed-price quote. No rough estimates, no scope creep surprises halfway through the build.

Plan before you build

Database schema, API structure, and authentication model designed and approved before UI design starts. This prevents expensive rework when technical constraints surface mid-build.

Working demos every two weeks

Agile sprints with real working software at the end of each. You see progress throughout the build, not a reveal at the end.

You own everything on completion

Source code, database schemas, deployment configuration, and documentation, all transferred to you on final payment. No ongoing dependency on us.

FAQ

SaaS development questions, direct answers

When does it make sense to build custom software instead of buying existing tools?

When the gap between what you need and what any existing product provides is large enough that workarounds cost more than building. This usually happens when your workflow has a specific step that no existing tool handles, when you need to integrate systems in a way that existing integrations do not support, or when a subscription to multiple tools would cost more than a one time build at scale.

How much does custom SaaS development cost?

A focused MVP with three to five core features typically starts in the range of $25,000 to $60,000 AUD. A full SaaS product with multi-tenant setup, subscription billing, admin dashboards, and third-party integrations runs $80,000 to $200,000+ depending on scope. We scope every project thoroughly before quoting. No rough estimates that turn into surprises.

How long does a SaaS build take?

A focused MVP typically takes 8 to 14 weeks from design sign-off to production deployment. A full featured SaaS product with advanced permissions, billing, and integrations runs 16 to 24 weeks. We work in 2 week sprints with working demos throughout, so you see real progress rather than a reveal at the end.

Do you do ongoing feature development after launch?

Yes. Most clients retain us monthly after launch for feature development, performance optimisation, security patches, and system management. The same team that built the product continues working on it. No onboarding cost, no context loss.

What tech stack do you use?

Next.js App Router with TypeScript for the frontend and API layer, PostgreSQL for the primary database, Supabase or Prisma for the data access layer, NextAuth or Clerk for authentication, and Stripe for subscription billing. We deploy on Vercel or AWS depending on your requirements. This stack is production-proven, well-documented, and easy to onboard future developers onto.

Do you handle hosting and DevOps?

Yes. We set up the full deployment stack: CI/CD pipelines, staging and production environments, uptime monitoring, error tracking via Sentry, automated backups, and scaling configuration. We hand over full credentials and runbooks at project end. You own the code and deployment.

Can you integrate with our existing systems?

Yes. We have built integrations with Salesforce, HubSpot, SAP, Zoho, Xero, QuickBooks, Stripe, and many other systems via REST APIs, GraphQL, and webhook connections. If the system has an API, we can connect to it.

Do we own the source code?

Yes. 100%. On final payment, all source code, database schemas, deployment configuration, and documentation transfer to you with no licensing fees or vendor dependency. Your team can maintain and extend the application independently after handover.
