Multi-tenancy
Every customer account isolated so one tenant can never see another tenant's data. The foundation of any SaaS, and the thing most prototypes get wrong.
Service · SaaS Development · Perth + Remote
Build your SaaS product, hardened by senior engineers.
Vibe coding makes a SaaS fast and cheap to start. It is also dangerous in authentication, payments and regulated data without senior oversight. Research finds AI-generated code carries roughly 1.7x more major issues and a 2.74x higher security-vulnerability rate. We build your multi-tenant, subscription product with AI assistance, then a senior engineer reviews every line and hardens it for real customers. Building internal tools and dashboards for your own team instead? That is App Development.

01Who it is for
For people turning an idea into a product they sell.
A SaaS product is something customers sign up to, log into and pay you for every month. That is a very different build to an internal tool.
We build customer-facing, multi-tenant, subscription products for founders, agencies and operators across Australia. Some are starting from a fresh idea. Some have a working internal tool that customers keep asking to buy, and want it turned into a sellable product. Either way the moment you charge external customers and store their data, the standard goes up. Multi-tenancy has to isolate every account. Billing has to reconcile. Auth has to hold. That is the work, and it is the work most no-code prototypes quietly skip.
Who we build SaaS fortypical
- ✓SaaS founders. You have an idea and want a real, sellable first version, not a demo that breaks on the second customer.
- ✓Agencies and studios. You need a productised platform under your brand, built once and resold across clients.
- ✓Operators with an internal tool. Something you built for your own team that customers keep asking to buy. We turn it into a product.
- ✓Vibe coders who hit a wall. You started in Lovable, Bolt or Replit, got 70% there, and the auth, billing or security is now the hard part.
02Scope
The parts of a SaaS that have to be done right.
Authentication and SSO
Sign-up, login, password reset, social and Google login, and SSO for business customers. Sessions, tokens and account recovery built to hold.
Stripe subscriptions and billing
Plans, trials, upgrades, downgrades, proration, failed-payment handling and invoices. Billing that reconciles and does not quietly lose revenue.
Roles and permissions
Owners, admins and members inside each customer account, with permissions that actually gate what people can do, not just hide buttons.
Admin dashboards
An internal control surface for you: see accounts, manage subscriptions, handle support, run reports and step into a tenant when needed.
Public API and webhooks
A documented API and webhook layer so your customers can integrate, plus the integrations your product needs to talk to other systems.
We host and run it too. Where the product lives, how it scales and how it stays up is AI Infrastructure, and we wire that in from the start rather than bolting it on later.
03Safety
Vibe coded for speed, reviewed for safety.
AI writes the code fast. A senior engineer reads every line before a single customer touches it.
The danger in a SaaS is concentrated in exactly the places AI gets wrong most often: an auth check that is missing, a tenant filter left off a query, a Stripe webhook that trusts the client, a secret committed to the repo. We treat the AI output as a fast first draft and harden it: authentication and tenant isolation tested, payment flows verified, secrets managed, dependencies checked. Australian Privacy Act obligations and the Essential Eight mitigations are designed in, not patched on. If you have already built something and want it checked or rescued, that is a Vibe Code Audit, and the deeper hardening work is AI Security.
Where unreviewed SaaS code breakshigh risk
- !Tenant data bleed. A missing tenant filter and one customer reads another customer's records.
- !Broken auth. An endpoint with no check. Anyone with the URL gets in.
- !Billing that does not reconcile. Webhooks trusted blindly, subscriptions out of sync, revenue lost quietly.
- !Leaked secrets. API keys and database credentials committed to the repo or shipped to the browser.
04Process
Scope, build, harden, launch and support.
01 · scope
Scope it first
We agree what the product is, who the customers are, the data it holds and the plan tiers. Fixed scope and figure in writing before any code.
02 · build
Build fast with AI
AI-assisted development drives the first version: multi-tenancy, auth, billing and core features, directed and steered the whole way.
03 · harden
Review and harden
A senior engineer reviews every line. Tenant isolation, auth and billing tested. Privacy Act and Essential Eight designed in.
04 · launch
Launch to customers
Hosting, monitoring and the production launch. Real sign-ups, real payments, real data, on infrastructure built to scale.
05 · support
Support and grow
We do not vanish at launch. Ongoing support, new features and the option to keep growing the product as you sign customers.
Want autonomous coding agents driving more of the build under senior direction? That is Agentic Coding, and we use it where it fits. We build in the platforms that suit the product, including Lovable, Bolt and Replit.

Frequently asked questions.
Pricing is on application because a SaaS varies enormously in scope. A focused first version with multi-tenancy, auth, Stripe billing and one core workflow sits at one end. A platform with SSO, a public API, multiple plan tiers and complex permissions sits well above that. To be honest about ranges: a genuine sellable first version typically lands in the low-to-mid five figures, and larger platforms run higher. We agree a fixed scope and figure in writing before any code is written, so there are no hourly surprises.
Most SaaS first versions are scoped, built and in front of real users within two to eight weeks. The simple end with one core workflow is faster. The slower end is multi-tenancy plus SSO, billing tiers and several connected features. We give you a clear timeline in the proposal before we start.
It is safe when the AI output is reviewed and hardened by a senior engineer, and unsafe when it is shipped raw. Research finds AI-generated code carries roughly 1.7x more major issues and a 2.74x higher security-vulnerability rate, and a SaaS concentrates risk in the worst places: authentication, multi-tenant data isolation and payments. We use AI for speed, then review every line and test the auth, tenant isolation and billing before a customer ever touches it.
SaaS Development is for a customer-facing, multi-tenant, subscription product that you sell to external customers, so it needs sign-up, billing, tenant isolation and an admin surface. App Development is for internal tools, dashboards and MVPs that your own team uses, where there is usually one tenant and no public billing. If customers will pay you a subscription and log in, it is SaaS. If your staff use it to run the business, it is an app.
Yes, and these are the parts we treat most carefully. Multi-tenancy with strict per-account data isolation, authentication including social login and SSO, and Stripe subscriptions with trials, upgrades, proration and failed-payment handling are core to every SaaS we build. They are tested specifically, not assumed to work.
Yes, completely. The code lives in your GitHub, on your infrastructure, under your accounts. You own one hundred percent of it. There is no lock-in to us, and another team could pick it up and keep going if you ever needed them to.
Yes. Plenty of founders get a SaaS to seventy percent in a tool like Lovable, Bolt or Replit and stall on the auth, billing, multi-tenancy or security. We start with a Vibe Code Audit to find what is broken, then fix and finish it. See the vibe-code-audit and fix-ai-app services for how the rescue work runs.
