SaaS Product Development
We are a SaaS development company, and your product is designed and built new for you. The tenancy model, the billing and the permissions are decided before anybody draws a screen. The price and the launch date are agreed in writing first, and most first releases go live in about 30 days.

Build the product your customers subscribe to.
Software sold by subscription earns every month instead of once. The work is in the parts nobody sees from outside: keeping one customer's data away from another's, charging the right amount on the right day, and letting an admin hand out access without calling you.
Revenue that repeats
Subscriptions bill themselves every month, so growth compounds rather than restarting.
One codebase, every customer
Each tenant gets their own data and settings from a single deployment you maintain once.
Priced how you sell
Per seat, by usage, in tiers, or a mix, changed later without a rebuild.
Yours to sell or raise on
The code, the data and the customer relationships stay with your company.

The product, the console and the way in.
A SaaS is four things that have to agree with each other. Pick one to see what goes into it.
App 01 of 04
Customer web app
The product itself, in the browser. It loads fast on a laptop in an office and still works on a phone in a car park.
- Sign-up and trialSelf-serve registration, email verification and a trial that ends without a support ticket.
- WorkspacesA customer invites their colleagues, and everyone sees the same data under one account.
- Roles and permissionsOwner, admin and member, with the fine-grained rules your product needs on top.
- Plan and usageWhat they are on, what they have used, and what happens at the limit.
- Search and reportingThe views a customer opens daily, built to stay quick as their data grows.
- NotificationsEmail, in-app and digest alerts, with per-user settings that stick.
App 02 of 04
Admin console
Your own back office. Support answers a question here without a developer opening a database.
- Every tenant in one listPlan, usage, health and last activity, searchable and filterable.
- Impersonation, loggedSee what a customer sees to reproduce a problem, with every session recorded.
- Plans and pricingCreate plans, move a customer between them and apply a discount without a deploy.
- Invoices and dunningFailed payments, retries and what was actually collected this month.
- Feature flagsSwitch a capability on for one tenant, a group, or everybody.
- Revenue reportingRecurring revenue, churn and expansion, reported from your own data.
App 03 of 04
Tenant admin portal
The screens a customer's own IT or ops lead needs, so onboarding twenty of their staff never reaches your inbox.
- Invite and remove peopleTheir administrator adds colleagues and revokes access the day somebody leaves.
- Single sign-onSAML or OIDC against the identity provider they already run.
- BrandingTheir logo, colours and sending domain on what their staff and customers see.
- Billing self-serviceCard on file, invoices to download and a plan they upgrade themselves.
- Their own audit trailWho changed what, exportable when their auditor asks.
- Data exportTheir records out in a readable format, whenever they want them.
App 04 of 04
API and mobile
The product other software talks to, plus a phone app when the work happens away from a desk.
- Documented REST APIVersioned endpoints with keys, scopes and limits, documented as they are built.
- WebhooksYour customers' systems hear about an event the moment it happens.
- IntegrationsThe tools your market already runs, wired in during the first release or after it.
- Mobile companionAn iOS and Android app for the parts that belong on a phone, when your product needs one.
- Import and migrationA new customer brings their spreadsheet and starts the same afternoon.
- SandboxA safe environment for a customer's developers to build against.
From sign-up to a paid subscription.
The path every customer walks, and the parts of it that decide whether they stay.
- 01
Your customer
They sign up
A trial starts in under a minute, with no call booked and no card taken.
- 02
Your product
The workspace is created
A tenant is provisioned with its own data, settings and starting roles.
- 03
Your customer
They bring their team and data
Colleagues are invited, records are imported, and the product fills with their own work.
- 04
Your product
Usage is metered
Seats, events or storage are counted as they go, and shown to them before any bill arrives.
- 05
Your customer
The trial converts
A plan is chosen, a card is stored and the first invoice is raised automatically.
- 06
You
You watch and support
Your team sees usage, health and revenue in the console, and steps in early when something stalls.
The modules a SaaS is built from.
Your costed plan names which of these go into the first release, and which follow it.
- Multi-tenant architectureOne deployment, strict separation. A query written today cannot read another tenant's rows tomorrow.
- Subscription billingPlans, trials, upgrades, proration and failed-payment retries, through Stripe or a gateway your market uses.
- Usage meteringSeats, events, storage or API calls counted accurately, then shown to the customer before it becomes a bill.
- Role-based access controlRoles, groups and per-object permissions, enforced on the server rather than hidden in the interface.
- Tenant onboardingSelf-serve sign-up, workspace creation, data import and an invite flow that works without you.
- Security and complianceEncryption, audit logging, data residency and the evidence a customer's security review asks for.
- Single sign-on and SCIMSAML, OIDC and automatic provisioning, the three letters that unlock larger customers.
- API and webhooksA documented public API with keys and rate limits, plus events your customers subscribe to.
- Admin and support toolingLogged impersonation, feature flags and plan changes, so support never needs a developer.
- Analytics for your customerDashboards inside the product that show them the value they are paying for.
- AI integrationWhere your product genuinely needs a model, we wire one in: drafting, classification, search over a customer's own data.
- Notifications and emailTransactional mail, in-app alerts and digests, on infrastructure that reaches the inbox.
Ways to charge for it.
Use one or combine them. The billing module handles the arithmetic and the admin console handles the exceptions.
- Per seatA price for each user in the workspace, counted as they invite colleagues.
- Usage basedCustomers pay for what they consume: events, storage, API calls or minutes.
- Tiered plansGood, better, best. Features and limits differ, and an upgrade takes one click.
- Annual contractsA year paid upfront at a discount, invoiced rather than charged to a card.
- Free trial or freemiumA limited free tier or a timed trial, with the upgrade prompt where it belongs.
- Add-ons and overageExtra seats, storage or modules billed on top, with clear limits before the charge.
Example month
52 paying workspaces, three plans
- 40 × Starter, $29 a month
- $1,160
- 12 × Growth, $79 a month
- $948
- Metered usage above plan limits
- $214
- 2 annual contracts, recognised monthly
- $500
Recurring, so next month starts here rather than at zero. Figures are an example: you set every plan and every rate.
Built for your kind of software business.
Tell us who subscribes and how they pay, and the product is designed around that rather than around a template.

A price and a date you can plan around.
- 01 · Before we start
Free costed plan
Tell us what the product does and who pays for it. You get the scope, a fixed price and a launch date in writing, free, whether you go ahead or not.
- 02 · Week 1
Tenancy and data model
How customers are separated, what a role is allowed to do and what gets metered. These decisions are expensive to change later, so they come first.
- 03 · Weeks 2 to 4
Build and test
Our team builds the product while testers work through every permission and billing path. A new version reaches your staging environment each week.
- 04 · From about day 30
Launch and support
We deploy to your own infrastructure, hand over the accounts and the documentation, then keep it patched, monitored and current.
Most first releases go live in about 30 days. A product with heavy compliance or many integrations takes longer, and your costed plan fixes the scope and the exact date.
What goes live first, and what follows.
Your costed plan splits the build into releases, each with its own fixed price and date. The first one is what a paying customer needs on the day you open.

What sets the price.
There is no price list, because no two products need the same build. Your fixed price comes from the scope in your costed plan, and these are the things that move it.
Get your fixed priceHow much product
The screens and workflows a customer pays for, and which are first-release.
Billing complexity
Flat plans are quick. Usage metering, proration and annual invoicing take longer.
Permission depth
Three fixed roles, or per-object rules a customer configures themselves.
Identity and compliance
Single sign-on, provisioning, audit trails and residency requirements.
Integrations
Each outside system you connect, and whether it has a usable API.
Design depth
A clean standard interface, or a fully custom design system.
The hard parts are decided before we build.
Your product is designed and built new for your business. What we bring is the order the decisions go in: tenancy before the data model, permissions before the screens, metering before the pricing page. Products that skip that order end up rewriting their database the year they find their first large customer, and that is the rewrite the fixed price and the fixed date are protecting you from.
After launch, we stay.
A SaaS is never finished. Customers arrive, dependencies age and somebody eventually asks for a security review.
Updates and patches
Frameworks, libraries and databases all publish security fixes, and a product left alone for a year accumulates every one of them. We keep your dependencies current, test each update against your product and release it, so nothing breaks quietly between one customer signing up and the next.
Monitoring
We watch the servers, the queues, the payments and the error rate around the clock. When something slows or fails we see it first and start on it, usually before a customer opens a ticket about it.
Billing support
Payment problems cost money directly, so they go first. Failed charges, stuck upgrades and invoices that disagree with usage are ours to chase. We deal with your payment gateway ourselves rather than passing their questions on to you.
New features
Your customers will ask for things, and the roadmap should answer them. Each addition is scoped, priced and dated in writing before work starts, exactly like your first release, so there are no open-ended bills.
Security reviews
Larger customers send questionnaires, and some of them send auditors. We keep the architecture documentation, the access controls and the audit trails ready, so answering takes days instead of weeks.

The product is yours, and so is everything needed to run it. Your team gets the code, the infrastructure, the deployment process and written documentation. Carry on with us, or bring in your own developers, whenever you decide to.

How much does it cost to build a SaaS?
It depends on the scope: how much product, how complicated the billing is, how deep the permissions go and which outside systems you connect. You get a fixed price in a free costed plan before any work starts, and it does not move unless you change the scope.
How long does it take to build a SaaS product?
Most first releases go live in about 30 days. A product with heavy compliance requirements or many integrations takes longer, and your costed plan fixes the scope and the exact date before we begin.
Single tenant or multi-tenant architecture?
Multi-tenant for almost every product: one deployment serving every customer, with their data separated in the database. You maintain one version instead of fifty, and a fix reaches everybody at once. Single tenant makes sense when a customer's contract demands their own isolated instance, and we build that as a deliberate exception rather than the default.
What tech stack do you use for SaaS?
Python with FastAPI and PostgreSQL on the server, React and Next.js in the browser, Redis for queues and caching, deployed in your own cloud account. We pick what suits your product and what your own developers could pick up later, and the choice is written into your costed plan before we start.
Can you add AI features to our product?
Yes, where your product genuinely needs them. Drafting, classification and search across a customer's own data are the usual ones. It is an integration inside your product rather than a separate offer, and the costed plan prices it like any other module.
Who owns the code and the customer data?
You do, both of them. The product is deployed into your own cloud account, the code is handed over with documentation, and your customers' data never sits anywhere you do not control.
Can you take over a SaaS somebody else built?
Often, yes. We start by reading the code and the infrastructure, then report back honestly on what is there and scope the work as fixed-price releases like any other build. Sometimes the answer is that a rebuild costs less than the repairs, and we say so even though it is the slower sale.
Do we get a mobile app as well?
Only if your product needs one. Most SaaS first releases are web, because that is where the work happens. When a phone app earns its place we build it for iOS and Android and publish it to both stores, priced separately in your costed plan.
Will it handle growth?
Yes. The tenancy model, the database indexes and the queues are built for thousands of tenants from the start, and we tune them as your numbers climb. Getting that wrong at the beginning is the rewrite that kills products, which is why it is settled in week one.
