SaaS products with tenancy, roles and a path to charge for value
A SaaS product is a business model sitting on engineering: isolation between customers, onboarding, permissions, usage, and a release cadence that does not break tenants. Hirvex Technologies builds multi-tenant web products and the operational habits around them. We do not pretend a single-tenant custom app is SaaS by renaming it.
Who this is for. Founders and product owners who intend to sell the same product to many organisations.
Problems we typically meet
These are the patterns that show up before a useful first release—not abstract “digital transformation” language.
- The “SaaS” codebase still clones a database per customer by hand.
- Permissions were designed for one company and collapse at the second tenant.
- There is no audit trail for who changed what in a shared environment.
- Billing, trials and plan limits were left as a later surprise.
How we approach the work
We design tenancy, identity and data boundaries first. Then onboarding, empty states and admin-for-your-admin. Billing integrations are added when the commercial model is known; we do not hard-wire a payment provider into the core if you are still pricing. Observability is part of the first production release.
What a serious first release can include
Scope is confirmed in discovery. This is the shape of work we are equipped to deliver—not a menu you must buy in full.
- Multi-tenant architecture and data isolation strategy
- Organisation, seat and role models
- Subscription-ready application structure
- Tenant admin and super-admin consoles
- Public marketing site plus authenticated product
- API access for your customers’ integrators
- Cloud deployment, staging and release discipline
What we need from you
A useful brief is better than a long one. If you can answer most of the following, we can propose a first slice instead of a theatre estimate.
- Who will use this, and what must they finish in a session?
- Which systems must stay (accounting, payments, identity, a shop)?
- What is already live that we should not break?
- Any hosting region, language or compliance rule that is non-negotiable?
- The date that actually matters—and why.
How an engagement runs
Four steps. No mystery bench.
Scope
We reply with clarifying questions and a first-release outline: modules, roles, integrations and what “done” means.
Build
Named engineers work in visible increments, with staging you can click and a weekly written status.
Run
Launch, handover and a support path. The system is yours to operate—not a black box we disappear from.
Questions we are asked
Can you take a custom app and turn it into SaaS?
Sometimes. If the domain logic is sound, we extract tenancy and identity. If the app assumed one company everywhere, that is a redesign, and we will say so before you fund it.
Do you handle payments and tax?
We integrate established billing providers. Tax, payouts and merchant accounts remain your commercial and legal responsibility.
How do you keep tenants from seeing each other’s data?
Through explicit tenancy in the data model, query discipline, tests around isolation, and reviews. It is not a middleware afterthought.
