    Building SaaS is different from building an app for one company. Every customer is a tenant whose data must never leak to another; pricing and plans change; onboarding has to work without a salesperson; and support, billing failures and usage limits are features, not afterthoughts.

    Our team builds and operates its own SaaS products - including a cloud ERP for construction contractors and a WhatsApp-first billing platform - so the unglamorous parts are designed in from the first sprint.

    See it working

    Many customers on one platform, and data that never mixes.

    See how a SaaS product signs up a new customer on its own, keeps every tenant's data isolated, bills through Stripe and gives your team safe support tools. Scroll through it, or run an event yourself.

    Live system
    1. 01 / 05

      Sign-up, workspace setup, sample data and in-app guidance let a new customer reach value without a demo call. Each new workspace becomes its own tenant from the first click.

    2. 02 / 05

      All customers share one app and one database, but row-level tenant isolation means one customer's records can never appear in another's account. Roles and permissions hold up under audit.

    3. 03 / 05

      Plans, trials, seats and usage-based pricing run on Stripe Billing, with dunning, invoices and a customer billing portal. Billing and tenancy are built first, so neither is an afterthought.

    4. 04 / 05

      Your team gets a back office to see usage, adjust plans and view an account safely when a customer asks for help, with every action scoped to one tenant and logged.

    5. 05 / 05

      Webhooks, API keys and the integrations customers ask for, such as QuickBooks, Google, Microsoft and WhatsApp, let the product fit into their stack as they grow.

    What we build

    SaaS Development: what it looks like in practice.

    Multi-tenant foundations

    Tenant isolation, per-workspace settings, invitations, roles and permissions that hold up under audit.

    Subscription billing

    Plans, trials, seats and usage-based pricing on Stripe Billing, with dunning, invoices and a customer billing portal.

    Self-serve onboarding

    Sign-up, workspace setup, sample data and in-app guidance so customers reach value without a demo call.

    Admin & support tooling

    An internal back office to impersonate safely, adjust plans, see usage and resolve tickets fast.

    Integrations & public API

    Webhooks, API keys and integrations your customers ask for - QuickBooks, Google, Microsoft, WhatsApp.

    Vertical SaaS

    Industry products with domain logic baked in - construction, property, memberships, field services.

    Pricing

    What it costs, in real numbers.

    SaaS budgets depend on how much of the platform layer (tenancy, billing, admin) you need on day one versus later. Typical ranges:

    SaaS MVP

    From $20k

    Auth, tenant workspaces, Stripe subscriptions, the core workflow and an admin panel - enough to sell to first customers.

    8–14 weeks

    Launch-ready v1

    $45k–$120k

    Roles, onboarding, integrations, analytics, audit logs and support tooling for a broader launch.

    3–6 months

    Scale-up work

    Quoted per phase

    SSO/SAML, usage-based billing, data exports, performance work and enterprise requirements.

    Ongoing phases

    Plan for cloud hosting that scales with customers, payment processing fees at Stripe's published rates, transactional email, error monitoring and backups. We model these per customer so your pricing covers them.

    How it works

    From first call to launch, no surprises.

    A written scope and a fixed price before any work starts, a working demo every week, and a clean handoff at the end.

    1. Step 011 week

      Product & pricing discovery

      Who pays, what they pay for, and which workflow must be excellent at launch.

    2. Step 021 week

      Architecture & fixed scope

      Tenancy model, billing model, data model and v1 scope with a fixed price.

    3. Step 032–3 weeks

      Design system & prototype

      Core screens and onboarding prototyped and tested with target customers.

    4. Step 04Bulk of timeline

      Build in sprints

      Weekly demos on staging, with billing and tenancy built first so they're never bolted on.

    5. Step 052 weeks + ongoing

      Launch & iterate

      Production launch, monitoring, and a post-launch sprint driven by real usage data.

    Is this right for you?

    An honest fit check.

    A strong fit if…

    • You've validated the problem with real prospects, or have a pilot customer lined up.
    • You want an engineering partner who has operated SaaS in production.
    • You need billing, tenancy and admin done right from the start.

    Probably not the right move if…

    • You haven't spoken to potential customers yet - start with a [prototype and validation sprint](/services/mvp-development).
    • You need a regulated fintech or medical platform certified at launch.
    Expert notes

    What we'd tell you on the first call.

    Single database or one per tenant?

    For most B2B SaaS, a shared database with strict row-level tenant isolation is cheaper to run and easier to evolve. Separate databases make sense for customers with contractual data-residency or isolation requirements. We decide this in the architecture phase, in writing, because it's expensive to change later.

    What a SaaS MVP really needs

    Sign-up, a workspace, one core workflow that's genuinely good, a way to pay, and an admin view for you. Not a settings page with 40 toggles. Our SaaS MVP cost guide breaks down where the money goes.

    Proof

    Software our team built and runs.

    We don't just build for clients - we operate our own SaaS products in production, so we design for the unglamorous parts: billing, support, uptime and change.

    FAQ

    SaaS Development: questions buyers ask.

    How much does it cost to build a SaaS product?

    Our SaaS MVPs start around $20k; a launch-ready v1 with roles, onboarding and integrations typically runs $45k–$120k. Scale-up work is quoted per phase.

    Have you built SaaS products yourselves?

    Yes. Our team builds and operates its own products, including a cloud ERP for construction contractors and a WhatsApp-first billing and collections platform.

    Do you handle subscription billing?

    Yes - Stripe Billing with plans, trials, seats or usage pricing, failed-payment recovery and a customer billing portal.

    Who owns the IP?

    You do. Code, infrastructure and data are in your accounts from day one.

    Can you help after launch?

    Yes. Most SaaS clients keep us on for iteration sprints and infrastructure care; others hire in-house and we hand over with documentation.

    Do you work with non-technical founders?

    Often. We translate the business model into a technical plan and explain every trade-off in plain English.
