SaaS development
SaaS products engineered for the second year, not just the launch.
Multi-tenancy, billing, teams, roles and analytics designed so the first customers and the thousandth run on the same foundation.
- Tenant isolation testedCross-tenant access is covered by automated tests.
- Billing tested with provider sandboxesRenewals and failures are exercised before launch.
- Audit trail for staff accessSupport actions on customer data are recorded.
Decisions that are cheap now and costly later
Tenancy bolted on after launch
Retrofitting isolation into a single-customer design usually means touching every query.
Billing logic scattered in code
Plan limits and entitlements checked in dozens of places make pricing changes risky.
No view of how customers use it
Without event data, roadmap decisions depend on whoever shouts loudest.
Support has no safe tooling
Staff need to see and fix customer data, but without roles and audit trails that is a liability.
What goes into a SaaS product
MVP and first release
A narrow product that proves value with real customers, built on foundations you will not throw away.
Learn more about MVP and first releaseMulti-tenancy
Tenant isolation at the data and permission level, with a model chosen for your customer profile.
Billing and subscriptions
Plans, trials, upgrades, invoices, taxes and failed-payment handling through a billing provider.
Teams and onboarding
Invitations, workspaces, seat management and first-run flows that get users to value.
Roles and permissions
Role-based access for customer admins and members, plus internal support tools with audit trails.
Product analytics
Activation, retention and feature usage measured with consent and without leaking personal data.
Scaling and reliability
Background jobs, caching, rate limiting, monitoring and backups sized for the growth you expect.
Reference architecture for a SaaS product
We adapt this to your case. Most products start as a modular monolith and split only when load or team size demands it.
Web app and marketing site
Public pages rendered for search, authenticated app for customers.
Application API
Typed endpoints, tenant-aware authorisation and rate limits.
Billing and entitlements
A single place that decides what each plan can do, fed by billing-provider webhooks.
Jobs and events
Queued work for emails, exports and syncs, with idempotent handlers.
Data and analytics
Relational storage per tenant model, plus an event stream for product analytics.
Operations
Logging, metrics, alerting, backups and staged deployments.

From concept to a running service
Product and architecture workshop
Target customer, core workflow, pricing model and tenancy approach are settled together.
Build the core loop
Sign-up, the central workflow and billing come first, so the product can be sold early.
Private beta
A small group of real users exercises it while we watch usage and fix friction.
Public launch
Monitoring, support tooling and onboarding are in place before marketing starts.
Scale and expand
Roadmap decisions follow usage data, with performance work scheduled rather than reactive.
Typical phases for a SaaS build
Typical durations for this kind of work. Real timing depends on scope, integrations and how quickly decisions are made.
Step 1: Workshop and scope
1 to 3 weeks
Core workflow, pricing model, tenancy and technical plan.
Step 2: Core product
8 to 16 weeks
Authentication, tenancy, the main workflow and billing.
Step 3: Beta
4 to 8 weeks
Real-user feedback, fixes and onboarding improvements.
Step 4: Launch and growth
Ongoing
Release cadence and scaling work by priority.

Questions about SaaS development
Still have questions? Tell us about your project and we will answer in one business day.
Book a callShould we start with multi-tenancy?
Yes, at least at the data model level. Adding tenant boundaries later is expensive. We pick a model that matches your customers: shared schema with strict scoping is common, separate databases suit stricter isolation needs.
Can you build just the MVP first?
That is how we usually start. The first release covers one core workflow and billing, built on structure that supports the rest, so you do not rebuild when it works.
Which billing provider do you use?
Usually Stripe, though Paddle and others work depending on tax and merchant-of-record needs. We keep entitlements in your own system so changing providers is possible.
How do you handle customer data and privacy?
We design for data minimisation, role-based access and deletion workflows, and keep analytics free of personal data. Legal requirements for your market must be confirmed with your own counsel.
