The Short Answer

What Is SaaS Development?

SaaS development is the process of building software delivered over the internet as a subscription service rather than installed and licensed per machine. One codebase serves many customers, each seeing only their own data, and the provider handles hosting, updates, security and availability centrally.

SaaS vs. Custom Software vs. On-premise

SaaS

Best at

Serving many customers from one product, recurring revenue, fast iteration

Trade-off

Stops where you set the boundary, then escalates.

Custom Software

Best at

Solving one organisation's problem exactly

Trade-off

No route to selling the same product repeatedly.

On-Premise

Best at

Buyers who require software inside their own infrastructure

Trade-off

Per-customer deployment, versioning and support overhead.

Establish the business model, target customer, pricing approach and the workflow the product must nail. Produce a scoped first release with an explicit out-of-scope list.

2
Architect

Architect

Settle tenancy, data model, permissions, billing structure, stack and deployment approach - documented with reasoning, before application code begins.

3
Design

Design

Interface design for the core workflow and the onboarding path, delivered as a component system the engineering team builds against directly.

4
Build in Sprints

Build in Sprints

Two-week increments ending in a deployed, usable build. Scope changes are traded against the plan rather than added to it.

5
Secure and Test

Secure and Test

Analytics, audit logging, error monitoring, access control testing and tenant isolation testing alongside functional and usability QA.

6
Launch

Launch

Deploy to production with staged rollout, onboard your first customers, and confirm billing and measurement work under real conditions.

FAQs

SaaS Development FAQs

SaaS development services cover building software delivered as a subscription over the internet. A full engagement includes architecture and tenancy design, application development, subscription billing, authentication and access control, self-service onboarding, analytics instrumentation, deployment and ongoing development.
Cost depends on the first release, tenancy model, billing complexity, integrations, compliance requirements and whether the work is a fixed phase or an ongoing product team. A useful estimate starts with a scoped release and documented assumptions, then separates discovery, build, infrastructure and support.
Timing depends on the workflow the product must nail, the number of roles, billing and onboarding scope, and how quickly decisions are made. A scoped first release is faster than a complete platform. After discovery, AB Ark can set milestones and the assumptions behind them.
Multi-tenant architecture runs many customers on one codebase and shared infrastructure, while keeping each customer's data, configuration and permissions isolated. It is what lets a subscription product onboard new customers without deploying a separate system for each one.
Multi-tenant fits a product you intend to sell repeatedly, with shared updates and self-service onboarding. Single-tenant, or a dedicated deployment, fits buyers who need the software inside their own infrastructure. The choice should be settled in architecture, before application code begins.
Yes. Migration can be phased: tenancy and data isolation, authentication, billing, onboarding, then a cutover that keeps the current product available until the subscription version is ready. The plan depends on how the existing system stores data and how customers are deployed today.
Code ownership follows the terms agreed for the engagement, and handover is planned from the start. AB Ark signs an NDA before discovery when the product, data or commercial model needs to stay confidential.
