SaaS Architecture Settled Early

CreateITivity takes software from first release to mature platform: multi-tenant B2B apps, APIs, data and cloud setup. Our developers also handle technical SEO, so customer separation, monitoring and fast server-rendered pages are planned together, and the product can grow and be found.

  • Tenant separation and role-based access from day one
  • A tightly scoped first release on a codebase you keep
  • Page speed and indexability planned in the architecture

What does the CreateITivity SaaS architecture team build?

CreateITivity designs and builds SaaS products for Canadian founders and established companies: first releases, multi-tenant B2B platforms, APIs, data layers and cloud setup. Tenant separation, automated tests and monitoring are part of the build from the start, and because our team also does technical SEO, public pages are server-rendered and fast.

  • A first release scoped tightly enough to reach users quickly, on a codebase you can keep
  • Tenant isolation and role-based access designed in from the first data model
  • Server-side rendering and Core Web Vitals planned at the architecture stage
  • The repository, cloud accounts and IP are registered to you
Engagements

Every stage of a software product

Pick the card that matches where your product is today. Each one explains how that work is scoped.

SaaS MVP Development

A working product in weeks, built to last

Launch a usable MVP quickly, without the shortcuts that force a rebuild a few months later.

See the approach

Multi-Tenant Architecture

Isolation, roles and room to grow

The difficult part of SaaS done properly: safe separation between customers, roles and permissions, and a model that scales.

See the approach

API Development & Integrations

Typed APIs, webhooks and third-party links

REST and GraphQL APIs plus the integrations your product depends on, documented, versioned and secure.

See the approach

Cloud Infrastructure & DevOps

IaC, CI/CD, monitoring and cost control

Infrastructure as code, pipelines and monitoring that make releases routine and late-night alerts rare.

See the approach

Database & Data Architecture

Schemas, migrations and speed

Data models that stay fast as you grow, with careful schema design, safe migrations, indexes and caching.

See the approach

SaaS Product Design

UX, onboarding and a usable design system

Product design that gets users to value quickly, with clear flows, onboarding and components engineers can build from.

See the approach

Technical Due Diligence

For investors, acquirers and founders

A frank assessment of a codebase and team before you invest, buy or scale, covering risks, debt and repair costs.

See the approach
Phases

Plan it, release it, then strengthen it

Each phase is short and reviewed with you before the next one is booked.

  1. Scope & architectWe agree the smallest release worth shipping and an architecture that can grow past it. Nothing gets built until you approve the plan.
  2. Build the MVPLogin, data model and deployment pipeline are done properly, and real users get access as early as the scope allows.
  3. Harden & scaleAs usage grows we add isolation, test coverage, monitoring and spending limits on the same codebase.
Standards

Built into every project we ship

Secure by default

Authentication, role-based access, secret storage and minimal permissions are set up in the first sprint.

Tested

Unit, integration and end-to-end tests run in CI, and a failing test blocks the merge.

Observable

Logs, metrics, traces and alerts are wired up so problems show on a dashboard before a customer reports them.

Cost-aware

Infrastructure is sized to real load, with budget alerts so the monthly cloud invoice holds no surprises.

Fast & crawlable

Public pages are server-rendered and checked against Core Web Vitals, so marketing pages can rank once they launch.

Documented

Decision records, runbooks and API references mean a new developer can get oriented without a long handover.

Typical projects

Where clients usually come to us

Some arrive with an idea and a deadline. Others have a product that has outgrown its first build. The same developers handle both.

Founder MVPs (0 → 1)

For founders who need a working product in users' hands soon. We keep the feature list short and the foundations solid, so version two extends version one.

Multi-tenant B2B platforms

Separate data per customer, roles and permissions, admin screens and billing. These are the parts of B2B software that are hardest to add later, so we design them first.

Scaling past the prototype

Your product works for fifty customers and creaks at five hundred. We add isolation, tests, monitoring and cost controls in stages, avoiding a rewrite where we can.

Internal tools & portals

Operations dashboards, client portals and admin tools that retire spreadsheets and repeated manual steps.

APIs & integration platforms

Back ends that partners and other apps connect to, with REST or GraphQL endpoints, queues, webhooks and documentation developers can follow.

Technical due diligence

An experienced review of a codebase before an acquisition, investment or handover, covering what is sound, where the debt sits and what it would cost to continue.

Common traps

Four reasons software projects stall

These come up again and again when a project lands on our desk mid-flight. Our builds are planned to avoid each one.

Built to scale before it works

Some teams design for a million users on day one and launch a year late. We build the simplest architecture that is correct for today and leave clear seams for later growth.

Multi-tenancy retrofitted late

Adding per-customer isolation to an app built for one customer is a costly rebuild, and it tends to arrive just as sales pick up. We put tenant boundaries and access rules into the first migration.

Shipped without observability

Without logs and alerts, a bug can sit in production for weeks until a client complains. Monitoring is installed with the first deployment.

SEO bolted on at the end

Whether a front end can rank is decided by how it renders. We choose server-side rendering and test page speed during the build, which avoids an expensive retrofit after launch.

Terms

Phased quotes and full ownership

Buyers worry most about runaway hourly bills and being tied to a vendor. Our terms address both up front.

Scoped, phased pricing

Work is split into phases, each with a defined scope and deliverable. You sign off on one phase before the next begins, and you can pause between them.

You own all of it

Code repositories, cloud accounts and intellectual property sit in your name from the start. We build inside your infrastructure.

Rolling terms after MVP

After the first release, we move to month-to-month terms. Keep us on for maintenance and new features, or hand the documented code to your own developers.

SaaS Architecture work at CreateITivity

Our commitments

When a company asks us to build its platform

Much of what makes a SaaS product costly to run is decided in its first two weeks, usually in a hurry. These are the choices we make on purpose, and what you own when we are done.

The decision we will not defer
Tenancy. How customer data is separated is the one choice that is painful to change later, so we settle it in the first week, on paper, with the cost of each option spelled out.
What "production-grade" means
Automated tests in the pipeline, logging and monitoring set up before launch, written runbooks, and a deployment your own developers can run without us.
Who writes the code
Engineers you can look up by name, not a revolving pool or a subcontractor you are never introduced to. About CreateITivity
What you own at the end
The repository, the cloud accounts, the credentials and the documentation. Nothing proprietary that you must pay us to keep running, and a live handover rather than a zip file.
What it costs
Discovery and architecture come first and are credited against the build. Delivery is then priced per phase in Canadian dollars, so each stage has its own number. How pricing works
The sequence

Settle the costly decisions while they are cheap

Platforms become expensive around year two because of choices made in the first week. So the hard-to-reverse decisions are made deliberately and documented before feature work begins.

  1. Week 1Discovery and the tenancy model
  2. Week 1–2Architecture documented with trade-offs
  3. Weeks 2–4A thin slice working end to end

Weigh it first

Choices that are costly to undo and the terms behind them

Founder questions

What to ask before a build starts

Useful whether you write code yourself or have never opened a repository.

Do you write the code yourselves?
Yes. Our developers build and ship the software. We can start with a due-diligence review or take over an existing codebase, but the engagement ends in working software.
Which technologies do you use?
Mainstream, well-supported choices: TypeScript, Node, Angular or React, Postgres and one of the major cloud providers. We pick tools your future hires will already know.
Will you take over a product someone else built?
Often. We begin with a short review so both sides know what is there, then stabilize and document it before adding features. Rewrites are a last resort.
How do you approach multi-tenancy and security?
Tenant boundaries, role-based access and per-customer limits are designed in the first data model. Adding them later costs far more, so we treat them as day-one requirements.
How long does an MVP take?
It depends on scope, which is why we cut scope hard. A focused first release on proper foundations can usually reach real users within a few months, and often sooner.
Can you look after SEO for the product as well?
Yes. CreateITivity runs technical SEO alongside development, so rendering, page speed and site structure are planned with the architecture and your marketing pages launch ready to be indexed.
How is a build priced?
Phase by phase. Each phase has a fixed scope and a deliverable, quoted in Canadian dollars before it starts. After the first release we work month to month, so you control spend.
Who owns the code and infrastructure?
You do. Repositories, cloud accounts and IP are in your name. Where you prefer, we build inside your own cloud account, including Canadian regions for data residency.
Do you support the product after launch?
If you want us to. We can hand a documented codebase to your team, or stay on for monitoring, maintenance and new work, including keeping page speed and search visibility from slipping.
How do you stop an MVP turning into technical debt?
Keep the scope small and the foundations real. Typed code, tests, a CI pipeline and a sensible data model go in from the first sprint, so the first release becomes the base of the product rather than something thrown away a year later.
