Exploring the Flexibility Behind Software-as-a-Service Platforms
One of the most common questions we hear from organizations considering a SaaS solution is: “Can we customize it to fit our unique needs?” The short answer? Yes, but how much flexibility you’ll have depends on how your SaaS platform is built, who owns it, and what level of control you’re looking for.
At Delta Systems, we specialize in building fully custom SaaS platforms and tailoring existing ones to better serve growing businesses. In this post, we’ll break down the levels of SaaS customization available, from off-the-shelf configurations to fully engineered solutions, so you can make an informed choice.
The Three Levels of SaaS Customization
SaaS customization typically falls into one of three categories:
1. Out-of-the-Box Configuration
This is the most basic level of customization, and the most limited.
What it includes:
- Adjusting user permissions and roles
- Choosing from pre-set themes or templates
- Configuring dashboards, fields, or notification preferences
- Turning specific features on or off
Best for: Teams that can adapt their workflow to fit a tool’s structure rather than the other way around. Think CRM systems like HubSpot or project tools like Asana.
Limitations: You’re restricted to the platform’s existing design. You can’t change functionality or add features that don’t already exist.
2. Platform-Level Customization (with APIs or Plug-ins)
This level involves extending an existing SaaS platform using the tools it provides, usually APIs, SDKs, or integration marketplaces.
What it includes:
- Integrating with third-party tools (Slack, Stripe, Salesforce, etc.)
- Creating custom workflows or automation
- Adding custom fields, rules, or reporting dashboards
- Building plug-ins, webhooks, or embeddable widgets
Best for: Businesses that like a particular SaaS platform but need to connect it to other systems or tailor specific functions.
Limitations: You’re still operating within the guardrails of someone else’s software. If the platform’s API doesn’t support what you need, or if the vendor removes functionality, you’re stuck.
3. Fully Custom SaaS Development
At this level, you control the platform. Every feature, integration, and interface is built around your business, not the other way around.
What it includes:
- Custom-built backend architecture and databases
- Personalized user interfaces for different roles
- Built-in logic, workflows, and reporting specific to your operations
- Direct access to all source code and cloud infrastructure
- Full control over feature updates, user management, and data ownership
Best for: Companies with complex workflows, security needs, or growth plans that off-the-shelf tools can’t support. Ideal for SaaS providers, enterprise apps, and organizations with proprietary processes.
Limitations: Custom SaaS takes more time and upfront investment, but the long-term ROI often outweighs the cost of constantly fighting a boxed-in tool.
Factors That Influence How Much You Can Customize a SaaS App
Even within these categories, your level of customization depends on:
Ownership and Licensing
If you’re using a subscription-based SaaS, you don’t own the software; you’re renting access. That limits how deeply you can change things. With a custom-built solution (especially if Delta Systems builds it for you), you retain full ownership and control.
Architecture and Flexibility
Some platforms are built modularly, allowing you to swap out or extend components. Others are rigid and monolithic, making customization costly or impossible without breaking something else.
Scalability Requirements
If your platform needs to scale alongside your customer base, customization must consider multi-tenancy, database optimization, and user-level access controls. That level of flexibility is often only achievable through custom development.
User Experience Goals
Want to deliver a branded, intuitive experience to multiple user types (e.g., admins, customers, partners)? That often requires building your own interface rather than modifying someone else’s.
