SaaS development for products customers renew without thinking about it.
Multi-tenancy, billing, roles, audit trails and the admin tools your own team lives in, built properly the first time, because every one of them is painful to retrofit.
- Multi-tenant from day one
- Billing that reconciles
- Built for your support team too
The moments a product needs SaaS foundations.
Most SaaS scaling problems trace back to decisions made in the first month. These are the points where getting them right pays off.
- 01
You're about to sell to many customers
One codebase has to serve every account safely, with each customer's data kept apart.
- 02
Every client has their own copy
You deploy a version per customer, and every fix has to be shipped five times.
- 03
Pricing is stuck in a spreadsheet
Plans, trials and upgrades are handled by hand, and invoices don't match what people were charged.
- 04
Enterprise deals keep stalling
Buyers ask for SSO, audit logs and role-based access, and the product doesn't have them.
- 05
Support runs on database queries
Your team can't see a customer's account or fix a problem without an engineer.
- 06
An internal tool could be a product
Something you built for yourselves is good enough that others would pay for it.
A new SaaS product and a modernisation are different jobs.
One is about getting the foundations right while it's still cheap. The other is about changing the engine without stopping the car.
| Consideration | New SaaS product | Existing app to SaaS |
|---|---|---|
| Starting point | New SaaS productAn idea or a validated MVP | Existing app to SaaSA working app, single-tenant or internal |
| First focus | New SaaS productTenancy and permissions before features | Existing app to SaaSAn audit of what's worth keeping |
| Billing | New SaaS productWired early, so pricing can change later | Existing app to SaaSMoved off manual invoicing in stages |
| Risk to manage | New SaaS productBuilding features before the spine | Existing app to SaaSDowntime and data migration |
| How it ships | New SaaS productFoundations, then features in sprints | Existing app to SaaSIncrementally, customers moved in batches |
Either way, tenancy, billing and permissions get designed in the first weeks. They're far cheaper to build at the start than to add once customers depend on the product.
The parts of a SaaS product that decide whether it scales.
Features win demos. Tenancy, billing and permissions decide whether you can still ship in year two. We build both, in the right order.
- 01
Multi-tenant foundations
Workspace and organisation models, invitations, seat management and hard data isolation between customers.
- Workspaces
- Invitations
- Seats
- Data isolation
- 02
Subscriptions and billing
Plans, trials, upgrades, proration, failed-payment recovery and invoices that match what the customer was actually charged.
- Plans and trials
- Proration
- Dunning
- Invoices
- 03
Roles and permissions
Granular access control your customers' admins manage themselves, without a support ticket for every change.
- Role-based access
- SSO
- SCIM
- Audit logs
- 04
Integrations and public APIs
Webhooks, OAuth apps, REST and GraphQL surfaces, and the documentation that makes them usable by someone else.
- REST
- GraphQL
- Webhooks
- API docs
- 05
Admin and internal tooling
Impersonation, usage dashboards and support tools. The product your own team uses all day is part of the product.
- Usage dashboards
- Impersonation
- Support tools
- 06
Modernisation
Taking a single-tenant app, an internal tool or an ageing codebase and turning it into something you can sell again and again.
- Audit
- Tenant migration
- Strangler rollout
From the first workspace to a product that runs itself.
The spine goes in first: auth, tenancy, permissions and billing. Features are quick once it's right, and slow if it isn't.
- 01
Model the domain
Tenants, users, roles and objects worked out before any code. Nearly every SaaS scaling problem starts here.
You get- Domain model
- Permissions matrix
- 02
Design the system
A component library and the core flows: onboarding, settings and billing, designed once and reused everywhere.
You get- Design system
- Core flows
- 03
Build the spine
Auth, tenancy, permissions and billing first, so every feature that follows inherits them for free.
You get- Auth and tenancy
- Billing live
- 04
Ship features in sprints
Two-week sprints on a staging environment you can use, with a demo and a decision at the end of each.
You get- Working build
- Sprint notes
- 05
Harden and launch
Load testing, security review, backups and runbooks before real customers depend on it.
You get- Security review
- Runbooks
- 06
Operate and extend
Monitoring, cost tuning, onboarding improvements and the roadmap, guided by what your usage data shows.
You get- Monitoring
- Roadmap
What we build is yours. In writing.
Software you'll run for years shouldn't tie you to the people who wrote it. Once the work is paid for it's yours outright, handed over in accounts you control.
- 01
Code and IP
Full ownership of the code and design files passes to you on payment. No licence fees, ever.
- 02
Your own accounts
Repositories, hosting, stores and domains are handed over in your name, not kept in ours.
- 03
Documentation
Setup guides, architecture notes and a record of key decisions, so any capable team can pick it up.
- 04
Confidentiality
We sign an NDA before you share anything sensitive, and treat your data that way throughout.
The things customers only notice when they're missing.
Every one of these is far cheaper to build at the start than to add once you have paying customers and real data to migrate.
- Isolation
Tenant isolation
Enforced at the database, not just in application code, so a bug can't leak one customer's data to another.
- Trust
Audit trails
Who changed what, and when. The first thing an enterprise buyer asks for, and the hardest to backfill.
- Growth
Self-serve onboarding
Sign up, invite a team and reach value without a call. The difference between selling and being bought.
- Revenue
Billing that reconciles
Webhooks, retries and edge cases handled, so revenue in your dashboard matches revenue in the bank.
- Fairness
Rate limits and quotas
Usage caps and fair-use protection, so one heavy customer can't slow it down for everyone else.
- Security
Security posture
Encryption, secret management and dependency scanning: the groundwork for a SOC 2 conversation later.
Boring where it counts, modern where it pays.
SaaS lives for years. We choose technology you can hire for and that will still be maintained when your product is on version five.

Recent work from the studio.
A look at what we've designed, built and launched recently.
Not quite a SaaS product?
If one of these describes where you are better, start there.
- MVP DevelopmentYou haven't confirmed people will pay yet, and need the smallest test first.
- Custom Software DevelopmentIt's a system for one business rather than a product sold to many.
- Product ModernisationThe product exists but the codebase is slowing every release down.
- AI SolutionsYou want AI features inside the product, with evaluations behind them.
- Ongoing Product EngineeringYou're live and need a steady team shipping the roadmap.
- UI/UX Product DesignThe experience needs redesigning before more gets built on top.
Questions
The things people
ask us first.
If yours isn’t here, send it over. We reply within 1 hour, guaranteed, and you’ll get a straight answer rather than a brochure.
What does multi-tenant actually mean for my product?
+
Every customer's data lives in one system but is strictly separated, so you deploy and improve one product rather than a copy per client. It affects the database, authentication and almost every query, which is why it belongs in the first week of design rather than the second year.
Can you convert our single-tenant app into a real SaaS product?
+
Yes, and it's a common reason people come to us. We start with an audit, then migrate incrementally: introducing a tenant model, moving customers across in batches and keeping the existing system running until the last one is over.
Which payment provider should we use?
+
For Indian customers, Razorpay handles UPI, cards and mandates well. For global subscriptions, Stripe Billing is usually the fastest path. If you sell worldwide and want tax handled for you, a merchant of record like Paddle is worth considering. We recommend based on where your customers actually are.
Do you handle SSO and enterprise requirements?
+
Yes. SAML and OIDC single sign-on, SCIM provisioning, audit logs, role-based access and data residency questions. These are what unblock larger deals, and they're much easier to design for than to retrofit.
Can you work alongside our engineering team?
+
Yes. We can own a workstream, pair with your engineers in the same repository, or build the foundations while your team builds features on top. We agree the split before we start.
What about ongoing maintenance?
+
SaaS is never finished. We offer ongoing support covering monitoring, dependency and security updates, cost tuning and feature work, either as a retainer or in agreed blocks.
