SaaS Web Development Services: What We Build

SaaS web development is building subscription software that customers use in a browser: multi-tenant architecture, sign-in and roles, billing, an admin console and integrations. As a SaaS development company, Groovy Web ships a SaaS MVP in 6-8 weeks from $30K and grows it into a full multi-tenant product.

Looking for a marketing website for your SaaS rather than the product itself? See our web development services.

Multi-Tenant Architecture

One codebase serving many customers, with each tenant's data kept separate by tenant-aware access rules at the database and API layers, and tested so one customer can never see another's data.

Auth, SSO & Roles

Email and OAuth sign-in, single sign-on (SSO) for business customers, team invites and role-based access control (RBAC) for every tenant.

Subscription Billing

Stripe Billing, Paddle or custom billing: plans, per-seat or tiered pricing, trials, upgrades and downgrades, invoices, a customer portal and automatic payment retries.

Usage Metering & Plan Limits

Track what each tenant uses (seats, API calls, AI credits), enforce plan limits in the product and pass the usage to billing for usage-based pricing.

Admin Console & Analytics

An internal admin panel to manage tenants, plans and support requests, plus product analytics and usage dashboards for your team and your customers.

API & Integrations

REST or GraphQL APIs with documentation, webhooks, and integrations with the CRMs, payment providers, calendars and messaging tools your customers already use.

Observability & Reliability

Logging, error tracking, uptime monitoring and alerts from the first release, with CI/CD and backups so you hear about a problem before your customers do.

Security & SOC 2 Readiness

Audit logs, encryption, least-privilege access and change management built in, so the platform can answer security questionnaires and support a SOC 2 audit.

AI Feature Integration

Large language model (LLM) features, AI agents and retrieval-augmented generation (RAG), added with evaluation and usage limits so margins hold as usage grows.

How these work in practice: Stripe pricing models, Stripe usage-based billing and the Stripe customer portal; AWS on tenant isolation; AICPA on SOC 2 reports.

AI SaaS

AI Features for Your SaaS Product

01

RAG Search & Q&A

Answers grounded in each customer's own data, with source citations and access rules per tenant.

Assistants that know each user's account and plan, and can explain, draft or take the next step inside your app.

Where you are today

Which SaaS stage are you at?

SaaS teams usually come to us at one of three moments. Pick the one that sounds like yours.

IDEA LIVE MVP IN 6-8 WEEKS

Building an MVP

You need one core workflow in front of paying users before the runway runs out, and agencies are quoting 4-6 months.

LEGACY Tenant A Tenant B Tenant C MULTI-TENANT, AUDIT-READY

Modernising a platform

Your platform is single-tenant, slow or hard to change, and enterprise customers are sending security questionnaires.

How Groovy solves it
  • Incremental modernisation, zero downtime as the target
  • Controls behind SOC 2, GDPR and HIPAA built in
  • Documentation and handover, no lock-in

Multi-Tenant Architecture Built for Audits

If your customers send security questionnaires, the architecture has to answer them. We build tenant isolation, audit logs, encryption and least-privilege access in from the first sprint, and prepare the evidence your auditor asks for. For payments, card data stays out of your systems through PCI DSS-compliant tokenised providers. A SOC 2 report is issued by an independent CPA firm after its examination, so no developer can hand you one.

SOC 2 B2B SaaS

Access control, change management, logging and monitoring controls built into the platform and pipeline.

GDPR EU customers

Data minimisation, consent, export and deletion flows per tenant.

HIPAA Health data

Encryption, audit trails and access logging for protected health information.

Architecture Decision

Single-Tenant vs Multi-Tenant SaaS: Which Do You Need?

Single-Tenant
Multi-Tenant
01 How It Works
Each customer gets their own app instance and database
All customers share one app, with data separated per tenant
02 Cost per Customer
Higher: every customer adds servers and upkeep
Low: shared infrastructure, adding a customer costs little
03 Updates
Each instance updated and tested separately
One release updates every customer at once
04 Isolation & Compliance
Strongest by default, often asked for by banks and hospitals
Strong when designed well: tenant isolation, per-tenant encryption, audit logs
05 Customisation
Deep per-customer changes, higher long-term cost
Configuration per tenant, one shared codebase
06 Best For
Enterprise deals that require dedicated infrastructure
Most B2B SaaS, startups and self-serve products
Multi-Tenant Our default for SaaS
1 Release Updates every tenant
Hybrid Dedicated instances for enterprise

Groovy has been a pleasure to work with. I have worked closely with them for many months now on a large and challenging project. From start to finish the communication has been great, they have worked on bugs and changes without issue and are just nice, hard working people. And most important of all, the end result is fantastic. I would not hesitate to recommend this company and am pretty sure I will be working with them on further projects in the near future

FAQ

SaaS Web Development FAQ

SaaS web development is building software that customers subscribe to and use in a browser, hosted and updated by you. It covers the product itself (multi-tenant architecture, sign-in and roles, billing, an admin console, integrations) and the cloud setup that keeps it running. It is different from building a marketing website for a SaaS company.
A SaaS MVP typically costs $30-60K, a full multi-tenant product with billing, auth and analytics $60-150K, and ongoing development $8-20K/month. Cost is driven by the number of core workflows, integrations, compliance needs and how much AI the product includes. See the full SaaS development cost breakdown or estimate your cost.
A focused MVP ships in 6-8 weeks: two weeks of scope and architecture, four weeks of build, a week of testing and hardening, then launch. A full multi-tenant product usually follows over the next few months, released in increments rather than one big launch. See what we build.
Yes, it is our default. Tenant isolation means every request is limited to the data of the tenant making it, which is separate from sign-in and permissions, so we enforce it at the database and API layers and test that one customer can never see another's data. For enterprise customers who need it, we can add dedicated instances. See single-tenant vs multi-tenant above.
We integrate Stripe Billing, Paddle or a custom setup. Stripe Billing supports flat-rate, per-seat, tiered and usage-based pricing, invoicing, smart payment retries and a customer portal for self-service plan changes. We also build the product side: plan limits, usage metering and per-tenant billing.
Ask for SaaS-specific proof (multi-tenancy, billing, SSO), not just web apps. Ask who owns the code, what happens after launch, and how pricing works: fixed scope suits a tightly defined MVP, a monthly team suits an ongoing roadmap. You can open our own SaaS products, read our case studies and check our Clutch reviews before you talk to us.
We build the technical controls an audit looks for, such as tenant isolation, audit logs, encryption, access control and change management, and prepare evidence for your auditor. SOC 2 is an attestation report issued by an independent CPA firm, not a certificate a development team can issue, so the report itself comes from your auditor. HIPAA and GDPR work follows the same approach.
You own 100% of the code and IP, with an NDA signed on day one. The code sits in your repository from the first commit, so you can move it in-house at any time with a full handover. Most clients continue with a monthly retainer for features and scaling, or hire SaaS developers as a dedicated team.
