SaaS is an operating commitment, not just software. We build multi-tenant platforms with the billing, onboarding, administration and telemetry that let a growing product stay operable and supportable. ## Fit For founders validating a SaaS idea, businesses productising an internal tool, and teams whose platform has outgrown its first architecture. ## Scope - **Multi-tenant architecture:** Tenant isolation, roles and data boundaries designed in from the first schema — the costliest thing to retrofit in a SaaS product. - **Subscriptions & billing:** Plan structures, trials, upgrades, proration and invoicing wired to a billing provider, with the edge cases — failed payments, cancellations — handled deliberately. - **Onboarding & self-serve:** Signup, workspace setup and first-value journeys that let customers succeed without a hand-holding call, with human support designed in where it matters. - **Administration & telemetry:** Admin tools for your team, usage metering, audit logs and the operational views that make support and capacity decisions evidence-based. ## Process 1. **Prove the loop:** Define the tenant journey from signup to renewed subscription, and what minimum product serves it. 2. **Build the spine first:** Tenancy, billing and roles before feature breadth — the parts that are painful to change later. 3. **Operate like a product:** Launch with telemetry, support tooling and a release process; review usage before adding scope. ## Examples ### A first SaaS release - Challenge: A validated problem needs a paid product with subscriptions, but the team must not over-build before revenue. - Approach: Scope one tenant journey end to end — signup, first value, payment — and defer everything that does not serve that loop. - Deliverable: A launched MVP with billing, onboarding and a documented growth backlog. ### Productising an internal tool - Challenge: An internal system works well and outsiders keep asking to buy it. - Approach: Separate tenant data from your own, add signup, billing and self-serve onboarding, and decide what stays internal. - Deliverable: A sellable multi-tenant product with a migration path for your own data. ### A scaling platform - Challenge: Early customers are happy; performance, support workload and manual operations grow faster than revenue. - Approach: Instrument the system, remove the operational bottlenecks — admin tooling, automation, data boundaries — and re-architect the hot paths. - Deliverable: A platform with telemetry, self-serve administration and a scaling plan tied to usage. ## FAQ ### Which billing providers do you work with? We integrate with established providers such as Stripe or Razorpay based on your market and entity. The provider account remains yours; the integration, edge cases and reporting are built to your plan structure. ### Can you take over an existing SaaS codebase? Yes, starting with a review of tenancy, billing, deployment and test coverage. That review determines whether incremental work or a phased rework is the honest recommendation. ### How do you price SaaS development? Per project, after scope is agreed. A first release and a full platform are different sizes of work, and the pricing page explains how quotes are prepared. ## Reference architecture A reference SaaS structure. Tenancy, billing and administration are the spine; features attach to it rather than growing around it. ### Tenancy Isolated records → Roles & invitations Keep every customer's data and access boundaries explicit, from the first schema onwards. Review: Test cross-tenant access attempts, role escalation and what deleted tenants leave behind. ### Commercial Plans & billing → Onboarding flow Turn signups into subscribed, successful tenants with trials, upgrades and failed-payment handling. Review: Check upgrade, downgrade, cancellation and refund paths against the billing provider's real behaviour. ### Operations Admin tooling → Usage & telemetry Give your team the views and tools to support customers and size capacity from evidence. Review: Verify support tasks — impersonation with consent, data export, plan fixes — are possible without direct database access. Illustrative planning model; scope and deliverables are agreed per project. ## Technology choices Tenancy and billing are the spine ### Platform Multi-tenant data model · Role-based access Establish tenant isolation and roles in the schema before feature work begins. ### Commercial Billing provider integration · Plan & entitlement logic Wire plans, trials, proration and dunning to the provider's real behaviour, including failed payments. ### Operations Admin console · Usage metering · Audit logs Give your team evidence for support, billing disputes and capacity decisions. ## Quality checks before handover ### Isolation verified Attempt cross-tenant reads and writes as every role; confirm nothing leaks through exports or logs. ### Billing edge cases Test upgrades, downgrades, cancellations, refunds and failed payments against the agreed policy. ### Support capability Confirm common support tasks are possible from the admin console with consent, without direct database access. ## Preparing for a project Bring the problem and target customer, expected pricing shape, competitor references and any existing code, data or design assets.
