SaaS Platform Development & Consulting

Launch, scale, and modernize multi-tenant SaaS with confidence.

We design and implement multi-tenant SaaS platforms from MVP to enterprise scale — and provide SaaS consulting for startups and established products alike. Whether you need startup SaaS development or SaaS modernization of an existing platform, our teams handle product architecture, subscription billing, tenant isolation, admin tooling, and the operational foundations required for recurring-revenue software businesses.

What is multi-tenant SaaS development?

Multi-tenant SaaS development is building one product that many customers subscribe to, with isolated data, shared infrastructure, billing, and onboarding. Reorigin does that as product engineering from Istanbul — new MVPs and modernization of platforms that already have tenants.

A SaaS that cannot take a paying customer’s card, invite a second user, or keep one tenant from reading another’s rows is not a product yet. The first release we aim at is the smallest system that can: an account, authentication, a plan, a bill, and the core workflow the customer pays for. Everything else is a later increment. We design tenancy during architecture. Retrofitting tenant isolation onto a single-customer schema is how MVPs become rewrites.

Startups usually need the MVP path: 10–16 weeks, often in the $40,000–$120,000 band depending on integrations and compliance, scoped after discovery. Established products come for modernization — tenant isolation that was implied rather than enforced, billing that cannot express usage, onboarding that needs an engineer on a call. We stay after launch when metering, plans, and scale are still moving. Delivery is in English and Turkish, on European hours, without a staffing-agency layer.

Single-tenant stacks still have a place: strict enterprise isolation, on-premises deployment, or a regulated workload that cannot share a process with other customers. We will recommend that when it is the cheaper way to pass a security review. The default for a subscription product is still one codebase, isolated tenant data, and shared infrastructure you can observe.

What you get

  • A tenancy model: shared schema, schema-per-tenant, or a documented hybrid
  • Authentication, invites, and roles inside a tenant
  • Plans, subscriptions, and a billing integration such as Stripe or Paddle
  • Onboarding that a new customer can finish without a founder on the call
  • Admin and customer views of usage, if the price depends on it
  • Tenant-aware logs and a way to see which customer an error belongs to
  • A production deploy with CI and a rollback path
  • A written note of what the next release should not break

Timeline and budget bands

A production-ready SaaS MVP with accounts, authentication, and billing is planned at 10–16 weeks and often $40,000–$120,000. The proposal after discovery is the number you can sign.

How we architect a SaaS

Name the tenant boundary

Every table, cache key, and background job names the tenant. A missing filter is a data leak, not a bug ticket for later.

Bill what you can meter

If the price is per seat, per site, or per API call, the meter exists in the first release. Packaging can change; the event should not be invented afterwards.

Onboard without us

The first customer after launch should be able to sign up, invite a colleague, and hit the empty state you designed. If that needs a Zoom, the product is not ready.

Keep a single-tenant door

Enterprise deals sometimes need a dedicated stack. We leave that as a deployment choice, not a fork of the product.

FAQ

Do you help with SaaS product strategy as well as engineering?

Yes. We support discovery, MVP scoping, technical architecture, and roadmap planning alongside full-stack implementation.

Which billing providers do you integrate with?

We commonly integrate Stripe, Paddle, and custom billing workflows depending on your business model and regions.

Can you scale a SaaS platform after launch?

Absolutely. We design for growth with modular services, monitoring, performance optimization, and ongoing feature delivery.

Do you offer SaaS consulting for startups?

Yes. We provide SaaS consulting for startups covering product-market fit, multi-tenant architecture, and a phased roadmap for startup SaaS development.

Can you modernize an existing SaaS platform?

Yes. Our SaaS modernization engagements re-architect legacy codebases, improve tenant isolation, upgrade billing and onboarding, and migrate to cloud-native infrastructure.

How much does it cost to build a SaaS MVP?

A production-ready SaaS MVP with multi-tenant accounts, authentication, and billing typically takes 10–16 weeks and often falls in the $40,000–$120,000 range depending on integrations and compliance. We scope after discovery so the first release can actually onboard paying customers.

Multi-tenant SaaS vs single-tenant — which is right?

Multi-tenant is the default for cost-efficient SaaS growth: one codebase, isolated tenant data, shared infrastructure. Single-tenant (or dedicated stacks) fits strict enterprise isolation, on-prem, or regulated workloads. Reorigin designs the tenancy model during architecture — not as an afterthought.

Why work with an Istanbul-based SaaS development team?

You get European-hour overlap, bilingual product delivery, and cloud-native engineering (Cloudflare, AWS, GCP) without a staffing-agency markup. Reorigin stays on as a product engineering partner after launch — billing, metering, and scale included.
