Our Enterprise Application Development Life Cycle

High Seas: Methodology


SaaS software development begins with information gathering that identifies and clarifies business goals, branding concerns, and the analysis of current market conditions and target audiences. The information uncovered guides which business, brand, and marketing problems we need to focus on and augment solutions for solving. 


We’ll set measurable goals and project expectations through interviews with stakeholders and customers, UX and CX research, as well as testing to evaluate the current state and functionalities of existing technologies.


Next comes the creation of Detail-Level wireframes and prototypes to determine what content will appear on each screen, how it’s organized, and how users will navigate. As part of Prototyping, our SaaS developers identify base-level user roles and functions, the intent and underlying system, and establish content, relationships, and pathways. Following these processes, interactive prototypes are built to test a concept or process to ensure we’re on the right course for each SaaS application development project.

4.Front-End Strategy & Dev

Front-End SaaS development starts with strategizing implementation with UX and Design teams, coordination with Content Management System (CMS) developers to inform project requirements, and technology assessments to implement the optimal technical architecture.

We then schedule the architecture development process, design a Javascript platform for React, Vue, and Angular libraries, and develop code for interactive, animated, and parallax elements.

The custom Front-End is then integrated with CMS platforms to set up information architecture, content blocks, and automated content flow. SCSS files are developed for all page elements from Mobile to Desktop, and iterative testing and quality control through each phase ensures each iteration functions correctly when added to the application.

5.Backend Dev

Our SaaS development company creates an application’s Backend with Full-stack web and mobile app development. We implement shared web, mobile, and native application backends with custom API and 3rd-party system integrations. Backend development also includes Plugin/Module setup or customized development, Bluetooth and Network connectivity and firmware update support for IoT, connected devices, and Wearables. High Seas Saas software development supports all major databases and data sources, including 3rd-party data integrations.


Choosing High Seas as your SaaS application development company means you’ll never receive a half-finished product. Before a new SaaS app is considered complete, it undergoes rigorous Quality Assurance testing that validates we’ve met all project goals, expectations, and business requirements. All design and development issues are resolved, and UX/UI is checked to ensure we’ve met all design and functionality expectations.


SaaS application development is never “fully complete;” the process is ongoing, requiring continuous updates, patches, and the refinement of features in subsequent software iterations. The hybrid iterative development cycle typically consists of one to two-week sprints focusing on implementing and refining subsets of features and software capabilities.

Each application iteration is guided by Usability Testing, A/B Testing, and Multivariate Testing that ensures we’re on course to achieving the most successful variations of a page or application with the best User Experience in the final iteration.


As your SaaS development company, we will perform app maintenance as needed, such as updates and patches. Upon request, the High Seas crew can provide ongoing software support to ensure it’s always optimally tuned.

What is our custom SaaS development process?

Our custom SaaS software engineering process consists of eight steps you can learn more about above. We begin with Discovery, then move through Defining, Prototyping, Front-End Strategy and Development, Backend Development, Delivery, Iterating, and Maintenance.

What is the cost to develop a custom SaaS application?

While the cost for SaaS development services can vary significantly depending on the complexity and scope of the project, we use a hybrid Agile approach that is great at working within your budget expectations.

What are the main challenges of SaaS development that your company might face?

There are four main SaaS software engineering challenges, but rest assured, challenges will be addressed and overcome with the help of an experienced SaaS development company.

  1. Custom third-party payment integration
    Payment functionalities are typically an essential component of SaaS applications. Our SaaS developers seamlessly create appropriate application parts such as services and facades to integrate external payment services. 
  2. Customizable System
    The entire SaaS system, from the interface up to the underlying system layers, needs to be fully customizable. When you need to customize a subdomain, layout, color scheme, templates, and more, it can be a challenging task, but if designed and tackled in an Agile, lean manner, it can benefit the system in the long run. 
  3. Guaranteeing Zero-Downtime Deployment
    Occasional frustration may arise during development because a system may not be fully accessible to a user when a new system version is released. However, our SaaS development company operates with a zero-downtime deployment strategy, meaning the application remains fully responsive at all times, even during the deployment process.
  4. Managing SaaS Subscription Lifecycle
    The best way to manage SaaS subscription systems is by using pre-built, ready-to-use solutions to organize and execute subscriptions, trailing, upgrading, canceling, and resubscribing processes. Proper management of the entire subscription lifecycle is the key to seamlessly integrating billing systems. 
Should you outsource the project to a SaaS application development company?

Choosing to outsource your SaaS project to a SaaS development company with years of experience, like High Seas, rather than pulling internal resources away from their core functions, almost always turns out better in the long run, both for costs and functionalities.

What is our custom SaaS development process?

Our custom SaaS software engineering process consists of eight steps you can learn more about above [Insert Jump Link]. We begin with Discovery, then move through Defining, Prototyping, Front-End Strategy and Development, Backend Development, Delivery, Iterating, and Maintenance.

How do we manage SaaS development projects?

We use a hybrid approach of Waterfall and Agile methodologies for most SaaS software development projects. Generally, UX and wireframes are necessary before we can begin the design phase. Design is necessary before we start development, but this ultimately depends on you and your project timeline.

If you approach us with an already functioning SaaS app that just needs to be updated, a Scrum-based Agile approach is typically the most appropriate. When we need to create a new app from scratch, a more linear approach is required.

Our Scrum-based Agile process consists of a series of one to two-week sprints. We target a different feature, component, functionality, or integration that goes through the entire design and development process during each sprint. After each two-week sprint, another functional increment is added to the application and can potentially be used immediately.

Every two weeks, you’ll have the opportunity to evaluate and reset project priorities, which is an expected and encouraged process. Our close collaboration with you throughout the development lifecycle ensures the High Seas crew provides the most beneficial technology, functionality, and design at each stage of development.
