Subscription software built to be billed, supported and trusted.
We develop SaaS products that include accounts, teams, subscription billing, permissions, dashboards, and admin tools. Our work spans MVPs to complete subscription platforms. From the outset, we address key issues such as data ownership, payment roles, and system recovery.
What do you need to decide before building a SaaS product?
Before estimating a SaaS product, clarify these five areas: tenant and user separation, role permissions, plan and billing setup, main workflows, and post-launch processes. These decisions significantly impact architecture, security, and testing, so address them before proceeding to design or pricing.
Estimating from a feature list alone hides most of the real work, which sits in accounts, billing, permissions, operations and recovery. Because these decisions are made first, the estimate that follows has fewer surprises, and any change in scope can be tied back to one of them in plain terms.
Five decisions that shape the whole build.
A feature list tells you what users see. These decisions tell you how hard the product will be to build, run and change.
What we settle with you first
- Identity and tenancy. How organisations, invitations, roles, impersonation and data isolation work. Mistakes here are the hardest to fix later.
- Commercial model. Plans, trials, entitlements, usage metering, invoices, taxes, cancellations and what happens after a failed payment.
- Operations. Admin tools, audit logs, support access, exports, notices and how the team recovers from failures.
- Evolution. API contracts, migrations, feature flags, monitoring and who owns the product once it is live.

Keeping every customer's data apart.
Customers trust you with their records. One leak between accounts can end a young product, so isolation is designed at the data layer.
Options we weigh with you
- Shared tables with a tenant key. Simple and efficient. Every query is scoped automatically, and automated tests try to break the boundary.
- Separate schema per customer. Stronger separation and easier per-customer export, with more work for migrations as the count grows.
- Separate database per customer. The most isolation, suited to strict clients, at higher cost and operational effort.
- Interface checks are not isolation. Hiding a button does not protect data. Scoping must hold even if someone sends a request directly.
Private areas for outside users are covered by our customer and staff portals page.
How billing is built so it stays correct.
Billing looks simple in a demo and becomes complex in production. We build it as a small state machine with clear rules.
- 01
Define plans and limits
Plans, trial length, seat or usage limits, add-ons and what each plan is allowed to do are written in one table.
- 02
Connect the provider
Stripe or a similar provider holds the card and the schedule. Your app stores references, never card numbers.
- 03
Handle webhooks
Provider events are signature-checked, applied once even if repeated and safe to receive out of order.
- 04
Link billing to access
A single entitlement check decides what a customer may use, so billing status and features never drift apart.
- 05
Cover the unhappy paths
Failed cards, retries, grace periods, upgrades, downgrades, refunds, tax and cancellation are all designed and tested.
- 06
Report and reconcile
Finance sees revenue, churn and failed payments, and a regular check compares provider records with your database.
From a small first release to a full platform.
Most clients start with a minimum release. A minimum product should reduce uncertainty. It should never skip authorisation or data protection.
How the product grows
- Release one. One complete journey for one user type, with sign-in, permissions, simple billing and basic usage tracking.
- Release two. What real users asked for: teams, more plans, integrations, better reports and tidier admin tools.
- Platform work. An API, webhooks, audit logs, role editing, export and deletion, and stronger monitoring as customers depend on you.
- Hardening. Load tests on realistic data, a disaster recovery rehearsal and security review before larger customers sign.
Founders can see how this works in practice on our full-stack web apps page.
Tools we use to build SaaS products.
We pick a small set of proven tools and explain why. The aim is a stack your next developer can read and trust.
Next.js and React
Fast interfaces and marketing pages in one codebase, with good support for search and accessibility.
Laravel and PHP
Queues, scheduled jobs, roles and admin tools arrive early, which suits subscription products with plenty of back-office needs.
Node.js and TypeScript
Good where a team prefers one language end to end or needs real-time features and many integrations.
PostgreSQL and MySQL
Relational data with strict constraints, which matter when billing and permissions rely on correct records.
Stripe and webhooks
Payments, invoices and tax handled by a provider, connected to your app through tested, verified events.
Observability
Error tracking, logs, uptime checks and cost alerts so a fault is seen before a customer writes in.
What goes wrong in rushed SaaS builds.
These patterns appear again and again in products we are asked to rescue. Each has a cheaper early fix.
| Criteria | What we do instead | What often happens |
|---|---|---|
| Billing status | One entitlement check used everywhere | Plan flags copied into many places and drifting |
| Payment events | Verified, repeat-safe, order-aware | Trusting the browser return, losing upgrades |
| Tenant isolation | Scoped at the data layer and tested | Hidden buttons and hope |
| Data export and deletion | Built early and tested | Discovered during a compliance request |
| Admin tools | Planned alongside the product | Engineers editing the database by hand |
Factors that decide effort and timeline.
We quote only after scoping. These are the factors that change the amount of work, and none of them is visible in a feature list.
User types and roles
Each additional role multiplies screens, rules and tests. Fewer, clearer roles make the product cheaper and easier to learn.
Billing complexity
One plan with a trial is simple. Usage metering, seat changes, regional tax and annual contracts need much more design.
Integrations
Accounting, CRM, email and customer tools each need mapping, error handling and monitoring on both sides.
Compliance and security
Medical, financial or enterprise customers may need audit trails, stricter hosting and security reviews before signing.
Migration
Moving customers from spreadsheets or another product means cleaning data and rehearsing the move more than once.
Design depth
A clear, tested interface takes time. Skipping testing with real users usually costs more later in support.
The admin tools a real SaaS needs.
Operations decide whether you can support customers after launch. These tools are small and save hours every week.
What goes into the admin side
- Account search and view. Support finds any customer, sees their plan, usage and recent errors, and acts without asking engineering.
- Safe impersonation. Staff can see what a customer sees, with a visible banner and an audit record of every action taken.
- Data export and deletion. Customers can leave with their data, and your team can erase accounts cleanly and prove it.
- Feature flags. New features roll out to a few accounts first and can be switched off in seconds if something is wrong.
Systems that have outgrown their first build may need legacy modernization instead of a new start.
SaaS development, answered.
Answers below cover the questions founders and product owners ask before they approve a SaaS budget.
How do you estimate a SaaS product?
We run a short scoping phase to settle tenancy, roles, billing, core workflows, integrations and operations. The estimate follows from those decisions. Without them, any number is a guess that will change once the hard parts appear.
What is a good SaaS MVP scope?
One complete journey for one type of user, correct sign-in and permissions, simple billing and a way to see usage and fix data. Breadth of features waits until real users prove which ones matter.
Do you integrate Stripe or other payment providers?
Yes. We connect Stripe and comparable providers for subscriptions, invoices and tax, with verified, repeat-safe webhooks. Where customers need local payment methods, we assess what each provider supports.
How do you protect customer data between accounts?
Tenant scoping is enforced in the data layer, tests deliberately try to cross the boundary, access is logged and every sensitive export is recorded. Interface checks are an extra layer, not the main protection.
Can I take over development later?
Yes. The code is in your repository with documentation, automated tests and a deployment guide. A new developer or team should be able to run it locally on their first day.
Can you improve a SaaS that someone else built?
Yes. We start with a review of code, data model, billing logic and deployment, then rank risks. The result may be targeted repairs, staged modernization or, with evidence, a rebuild of one part.
What affects timeline and cost?
The number of user roles, billing complexity, integrations, compliance needs, data migration, design depth and the level of testing. We describe timelines as ranges tied to those factors and avoid promising dates before scoping.
Turn your product idea into a service customers pay for.
Describe the product, the customers and how you plan to charge. You will get a short written scope that settles the key decisions and shows what drives the cost. The scope you receive names every assumption, so changes later are discussed openly against the original plan.
