SaaS platforms

Multi-tenant products with billing, roles, onboarding and analytics built in from day one.

Engagement
Phased build with a named team
Typical timeline
14–16 weeks to first commercial release
Starts with
A decision session on pricing, because the billing model dictates the architecture.
01The situation

You have paying customers on a product that was never designed to have more than one. Every new account means a manual set-up, a spreadsheet recording who is on which price, and an invoice somebody raises by hand.

Why it matters

A product you can sell subscriptions to, not a demo.

The surface that sells, engineered like software.

What we build

Concrete artefacts, handed over and documented.

  1. 01

    A tenancy model enforced in the database, so one customer cannot read another’s data even if the application has a bug

  2. 02

    Billing on Stripe: plans, trials, proration, failed-payment recovery, and the tax treatment for each region you sell in

  3. 03

    Self-serve onboarding, sign-up, workspace creation, invitations, a useful first-run state, so a customer can start without you

  4. 04

    Roles and permissions, including the internal admin view your own support team needs on day one

  5. 05

    Product event instrumentation from the first release, because the retention questions arrive in month nine and need history

  6. 06

    A release pipeline with staging, feature flags and rollback, so shipping stops being an occasion

What changes

01

A customer can sign up, pay and reach value without anyone on your team touching the account

02

Failed cards recover automatically rather than turning into churn nobody noticed

03

You can say which accounts use which feature, which is the conversation renewals depend on

How it runs

  1. Weeks 1–3

    01Architecture and billing model

    Pricing decisions come first, because whether you charge per seat, per workspace or per usage changes the database.

  2. Weeks 4–12

    02Core platform

    Tenancy, authentication, permissions, billing and the product surface, released to a staging tenant continuously.

  3. Weeks 13–16

    03Onboarding, analytics and launch

    The self-serve path, the instrumentation behind it, and a controlled launch to your first cohort of accounts.
