Notion Tech builds subscription software (SaaS) for founders and businesses in Australia: multi-tenant platforms with sign-up, billing, roles and admin tools. We build and operate two SaaS products ourselves, Rostery and AuditCore, so we know what it takes after launch day too.

one platform
The product is only half of a SaaS business. We build the other half too.
Each customer’s data kept fully separate, with the security rules enforced in the database.
Self-service sign-up, guided setup and sample data so new customers see value on day one.
Stripe plans, trials, upgrades, invoices and Australian GST handled correctly.
Owner, admin and staff roles, feature gating by plan and a full audit log.
Your own back office to manage customers, plans, support and usage.
Assistants, document reading and insights that are part of the product, not an add-on.
Shipping a SaaS product is the easy part. Keeping it fast, secure and supported for paying customers is where products succeed or fail. Rostery and AuditCore taught us where the real work is: data separation between customers, billing edge cases, onboarding that does not need a phone call, and releases that never interrupt a working day.
When we build SaaS for a client, those lessons are built in from the first sprint. You get an architecture that has already carried real customers, not one we are trying for the first time on your budget.
Data separation enforced in the database
Staged releases with no downtime
Monitoring, backups and alerts from day one
Help content and in-app guidance
We start with the smallest version that a customer would pay for: one core job done well, sign-up and billing. That goes live in weeks. Real usage then decides what comes next, which keeps the budget on features that customers actually use.
As the product grows we add the pieces that make a SaaS business run: plan limits, usage reports, integrations, mobile apps and an admin console for your support team.
Rostery serves care providers with rostering, a worker app on iOS and Android, NDIS claims, invoicing and payroll exports, on one multi-tenant platform with Stripe subscriptions.
We designed, built and run every part of it.
Fixed scope, fortnightly demos, no surprises on price.

It depends on the core feature, the number of user roles and whether you need mobile apps. We scope an MVP first and quote it as a fixed price in AUD, then plan later stages from real feedback.
Most MVPs take 8 to 14 weeks, including sign-up, subscriptions and the core feature.
One platform that serves many customers, with each customer’s data kept separate. It is cheaper to run and easier to update than a separate copy for every customer.
