SaaS development services for multi-tenant B2B platforms.
RAITHub's SaaS development service builds multi-tenant B2B products where one customer can never see another customer's data, and tests prove it on every build. Tenant isolation, permission-based roles, Stripe billing and an audit log go into the first release, because retrofitting them after customers arrive is slow and risky.
What's included
- Organisations, memberships and invites, with rate-limited sign-in
- Roles built from permissions, not hard-coded admin checks
- Tenant isolation in PostgreSQL, with row-level security where it fits
- Stripe subscriptions, metering, invoices and dunning
- An append-only audit log each tenant admin can view and export
- Error tracking, structured logs and alerting
How it works.
Every phase ends with something you can read, run or check, and you decide before the next one starts.
Technical audit
A free 15-minute call about the product, the users and the constraints. You hear honestly whether RAITHub fits.
Architecture spec
Scope, data model and screens written down and reviewed by the founder. Nothing is built until you sign it.
Build, weekly demos
Working software every Friday. Every pull request gets a branch preview and must pass the test suite in CI.
Hardening + handover
Security, load and regression checks, then launch on accounts you own and a walkthrough of the runbooks.
Proof from systems RAITHub built.
Numbers are counted from the repositories, not estimated.
Sundor Skin
12 staff roles from 88 permission codes, row-level security on buyer-scoped tables, and a security suite that tries to read other buyers' data.
PropDesk
Property-management SaaS with 4 user roles, Stripe rent collection and 5 daily automation jobs.
TheSkinProof
5 role-based portals in the founder's own marketplace venture, built and run by RAITHub.
Fixed scope or a dedicated team. No published rates.
Every engagement starts with a free 15-minute technical audit and ends in a fixed, written quote. For market ranges, read what it costs. The pricing page explains both models.
A first release is fixed-scope at a fixed price. Once the product is live and the roadmap keeps moving, most SaaS work suits a dedicated monthly team: the same people, a predictable rate, month-to-month. Either way you get a written estimate with its assumptions after the free audit.
When RAITHub is not the right fit.
Saying no early is cheaper for both sides than a project that was never going to fit.
Your enterprise buyers require your vendor to hold SOC 2 or ISO 27001. RAITHub is not certified, though it builds the controls your own auditor tests.
The product is a regulated fintech or health platform and you have no compliance partner.
The main product is a native mobile app. RAITHub builds web apps and PWAs.
You want engineers embedded under your own management. RAITHub does not offer staff augmentation.
SaaS Development questions
Straight answers to what buyers ask before they book a call.
What does RAITHub's SaaS development service include? +
Tenant isolation, organisations and invites, permission-based roles, Stripe billing, an audit log, observability, tests and CI, plus runbooks at handover. The scope is fixed in a signed architecture spec before production code starts.
How do you stop one tenant from seeing another tenant's data? +
Every query is scoped to the tenant, PostgreSQL row-level security backs it up where it fits, and CI runs tests that deliberately try to read another tenant's records. On Sundor Skin, CI fails if a buyer-scoped table has no row-level-security policy.
How long does it take to build a SaaS product? +
A focused first release typically takes 4 to 6 weeks at a fixed scope. Platforms with several portals or heavy integrations take longer and are delivered in phases, often by a dedicated monthly team.
How much does SaaS development cost? +
RAITHub publishes no rates. After a free 15-minute technical audit you receive a fixed quote, or a monthly dedicated-team rate, with the assumptions written down. The SaaS MVP cost breakdown covers market ranges.
Can you help us pass a SOC 2 audit? +
RAITHub can build the controls an auditor tests, such as access control, audit logs and change management. The SOC 2 report covers your company, not your development partner, and RAITHub itself is not certified.
Can you take over an existing SaaS codebase? +
Yes. That starts as a code rescue: a 2-week diagnostic, a written risk register and a fixed-scope plan, so the foundations are stable before new features go on top.
