custom software by Purple Moon Designs
5 April

We’ve been working with businesses to create custom software that works for them for years. Based in Glasgow we specialise in designing and building tailored web and mobile applications that streamline operations, reduce overheads and remove the unnecessary friction found in off-the-shelf systems. This is a guide, a knowledge resource and a bit of behind the scenes into our approach to custom software development.

What Is Custom Software and Why Should You Care?

Custom software is software built for your business, your needs and your workflows. Unlike pre-packaged platforms that try to fit everyone into the same mould, custom software adapts to you. It’s efficient, it’s lean and it often pays for itself in the time it saves and the confusion it removes. Not to be mistaken with web design and development which focuses on the front-end and to showcase your features to the visitors and potential customers.

We’ve seen this time and again—especially with our SWES Project Management Software, built for electrical contractors. It helped teams get on board quickly with minimal training, offered clear task visibility and just worked. No bells and whistles—just practical, easy to use functionality built around the people who use it.


Why Businesses Choose Custom Software

1. It Just Makes Sense

When you’re juggling tools that don’t talk to each other, software systems with per-user fees and support that never quite gets what you do – custom software development is the obvious solution. We’ve seen businesses cut down hours of admin, avoid duplication of effort and reduce mistakes just by switching to tools made for them, ensuring compatibility with various operating systems. Yes, you can use tools like Monday.com or another great one ClickUp. But with these tools you are down to learning how to use them, teach your team and you’ll most likely won’t have a need for half of the features you pay for.

2. You Save More Than You Think

While the upfront cost of developing software can be higher than buying something off the shelf, the long term savings are significant. No per-user costs, no surprise charges and no need to constantly retrain staff to fit new systems. Everything’s built around what you already know.

3. Growth Without Growing Pains

Custom software scales naturally with your business. Whether you’re adding team members, expanding locations or introducing new services your system grows with you. And since we’re not tied into expensive licensing models, growth doesn’t mean higher fees.

Real-World Benefits We’ve Delivered

SWES Project Management SoftwareWe built a simple system for electrical contractors who needed a reliable, user-friendly project management tool. Features included:

  • Task allocation and progress tracking
  • Mobile friendly interfaces for site based teams
  • Minimal training required for adoption

This is the kind of project that shows why bespoke software works. The guys on-site didn’t need to learn new processes—they just used the tool naturally.

Less Maintenance, Less Stress

Our clients comment regularly on how little time they spend maintaining their software systems after launch. With clear documentation, support that understands your business and software that’s clean and modular there’s less firefighting and more forward planning.


What to Know Before Starting a Custom Software Project

Know Your Needs First

Before writing a line of code know what your biggest bottlenecks and goals are. Custom software isn’t just about replacing what you do—it’s about improving it.

Don’t Overcomplicate It

One of our core values is to build tools that are easy to use. Too many features can confuse users and increase the chance of errors. Start simple. You can always build on it later (and we often do as part of further development).

Choose the Right Development Team

Look for a software developer who listens. Someone who wants to understand your business before they build. At Purple Moon Designs we take time to learn how our clients operate before making any technical suggestions, so each project is overseen by an experienced software engineer.

The Role of Software Developers in Custom Software Development

Software developers are the backbone of custom software development. They design, develop and test software applications tailored to meet the unique needs of a business. This requires a deep understanding of the client’s requirements and the ability to translate those needs into functional and efficient software solutions.

Developing bespoke software involves using a variety of programming languages and technologies whether for web or mobile applications. Software developers must be well versed in software engineering principles including design patterns, testing and deployment. Their technical expertise ensures the software solutions they create are robust, scalable and maintainable.

Beyond technical skills effective communication and project management are key. Software developers work closely with clients to understand their needs, provide regular updates and ensure the final product aligns with the client’s vision. This collaborative approach helps deliver software solutions that truly make a difference.

Software Engineering Principles

Software engineering principles are key to building good custom software. These principles provide a framework for creating software systems that are efficient, scalable and easy to maintain. Here are some of them:

  • Modularity: Breaking down complex projects into smaller, more manageable components makes the development process easier and the software easier to understand and maintain.
  • Reusability: Designing software components that can be reused across different applications saves time and resources making the development process more efficient.
  • Scalability: Ensuring software applications can grow with the business is critical. Scalable software can handle increased load and new features without significant rework.
  • Maintainability: Software should be designed to be easy to update and maintain. This reduces the long term costs and effort required to keep the software running smoothly.
  • Testability: Developing software that is easy to test ensures any issues can be found and fixed quickly leading to more reliable and robust applications.

By following these principles software developers can build custom software that meets the immediate needs of their clients and stands the test of time.

Before You Start Your Custom Software Project

Know the Problem You’re Solving

Don’t chase features. Focus on solving real, everyday problems for your team.

Think Long Term

Build with tomorrow in mind. Even if you start small make sure your software solution can evolve.

Communicate Clearly

You don’t need a computing science background, but it helps to be clear about what success looks like. We translate the tech stuff—so you don’t have to.


Things to Watch Out For### Hidden Fees

Be careful of platforms that charge per user, per month or per update. These costs add up fast. With custom software you own it. You’re not renting it.

Feature Creep

Some projects stall because they try to do too much too soon. Focus on the 80/20: what’s the 20% of features that will give 80% of the benefit?

Poor Handover or Documentation

If your system breaks and only one person knows how it works you’re in trouble. We ensure clear documentation and structure so your software stays maintainable.


Common Issues in Custom Software Development

Custom software development is a complex process with its own set of problems. Understanding these problems is the first step in solving them and delivering good software.

  • Understanding Client Requirements: One of the biggest problems is getting a deep understanding of the client’s needs. This requires good communication and a thorough discovery phase so the final product matches the client’s vision.
  • Managing Project Scope: Custom software projects can get complex fast. Managing the project scope is key to keeping the project on track and within budget. This means setting clear goals and milestones and regular progress reviews.
  • Software Quality: Good software is critical to client satisfaction. This means testing and validation throughout the development process to ensure the software is reliable and works as expected.
  • Cost Management: Custom software development can be expensive. Good cost management is key to keeping the project within budget. This means planning, monitoring and adjusting as you go.

By knowing these problems you can develop strategies to overcome them and deliver custom software projects.

Measuring Success in Custom Software Development

Measuring custom software development success is key to ensuring the software meets the client’s needs and provides a good return on investment. Here are some key metrics:

  • Client Satisfaction: Feedback through surveys and direct communication helps gauge how well the software meets the client’s expectations and needs.
  • Software Quality: Testing and validation is key to ensuring the software is reliable, works well and has no bugs.
  • Project Timeline: Monitoring the project timeline helps ensure the software is delivered on time. Delays impact client satisfaction and cost.* Cost: Keeping the project within budget is key. Regularly reviewing expenses and adjusting as needed helps manage costs.
  • Return on Investment: Ultimately the software should provide a good return on investment. This can be measured by improvements in efficiency, cost savings and other business benefits.

By focusing on these metrics software developers can deliver successful custom software projects that add real value to their clients.

Technologies We Use
