Should I use Power Apps?
Microsoft Power Apps is a solid choice if you have immediate needs to address and semi-technical users who are interested in learning and using Power Apps. The relative speed and ease of Power Apps allows you to deploy applications with minimum hassle and strain on internal teams.
Power Apps fosters collaboration among team members, enabling them to work together to achieve innovation and celebrate collective achievements.
Even if you don’t have a concrete idea of an application’s requirements, Power Apps can act as a great starting solution that helps you establish the actual requirements you are trying to fulfil. They’re also a quick and easy way to modernise your legacy technology.
What are the drawbacks of Power Apps?
While Power Apps’ pre-built templates-style approach allows developers to build applications quickly, the downside is that the functionality of those apps is limited to the features available. For example, there are limited customizations available in Power Apps builds in terms of UX, unlike in custom-built applications. Additionally, the lack of premium features in these pre-built templates can restrict the app’s capabilities, making it challenging to achieve significant return on investment (ROI) and support broader digital transformation efforts.
If you want your app to have a feature that isn’t there, or if you need scalable solutions that can adequately support your business as it grows, Power Apps might hold you back.
That said, the drawbacks are just as much about the people involved as they are technical. For example, the original authors of your apps might not be available or even willing to offer you the level of support you need over time, which can put mission-critical functions at risk.
What’s more, as these proprietary stacks evolve, there is a constant need to keep up to date. Citizen developers may struggle to keep up with demand as applications become more complicated and stray away from the required governance processes. For these reasons, they can begin to hinder operational efficiency, make it harder to scale the business, and put greater strain on internal teams.

SaaS
This software distribution model gives you access to cloud-based applications at a fraction of the cost of custom builds. SaaS applications can provide essential resources, such as links to policy guides and contact information, which are crucial for a smooth onboarding experience. But short of finding the perfect SaaS application, you’ll be investing a lot of work, money and time into a proprietary solution.
Why are businesses opting for SaaS?
The SaaS market, although not new technology, is continuing to grow at a rapid rate. In fact, the cloud application market is expected to hit a value of $168.6 billion by 2025.2
Considering that SaaS customers essentially “rent” a pre-built application’s capabilities via a licence rather than owning them outright, plenty of businesses opt for this to save upfront and maintenance costs, as well as reduce the amount of time it takes to get an application up and running. This makes SaaS a very attractive option for younger businesses on tighter turnarounds.
Since data is stored by the third party, you’re guaranteed secure data storage, saving costs and setup for a young business. Additionally, businesses can tap into various Microsoft 365 services to access and integrate data, enhancing processes like employee onboarding.
Should I use SaaS?
The SaaS model has exploded in recent years, thanks to its accessibility, cost-effectiveness, and simplicity. In an environment where companies need to move fast and streamline business processes, SaaS solutions are primarily focused on providing quick access to quality products. It’s no surprise that SaaS products like Slack, Zoom, Office 365, and Salesforce are so popular.
Simply put, if there’s a SaaS product that completely fulfils all your requirements — and is within your budget — then this is likely the best, most effective solution for your business.
This is especially true for fast-moving startups, which should only ever consider building their own business applications once they have outgrown a SaaS product’s capabilities.
What are the drawbacks of SaaS?
What you gain in convenience, you lose in control and visibility. SaaS vendors handle everything to do with their products, including updates and new features. End users are at their mercy, with close to zero say in the direction the product takes. In some cases, SaaS companies can fail and their products can be decommissioned altogether, leaving your business in the lurch.
Because you don’t own the SaaS products you use, there are limited options for customization. Additionally, slower speeds than custom-built apps can become an issue over time. This has major ramifications for the following:
- Scalability.
- Operational efficiency.
- Strain on your internal teams.
With all this in mind, if a SaaS product isn’t a perfect fit in terms of requirements, the drawbacks likely outweigh the potential benefits.
Custom-built applications
Although they’re a big financial investment, these applications are designed to fit your every need, both immediately and long-term.
Custom-built applications can help businesses manage operations across multiple locations, efficiently tracking visitor counts and equipment maintenance to meet unique operational challenges.
Why are businesses opting for custom-built applications?
Because custom application development involves designing, building, and implementing software applications from scratch, plenty of businesses feel they get more control over the final product.
A custom-built system provides a structured approach for managing data and operations, ensuring that key business processes are tracked and managed effectively.
Additionally, the fact that they’re designed with the aim to fulfil your specific business requirements makes them a far better solution than their competitors in terms of scalability. These applications can be accessed on various platforms, including Windows devices, ensuring versatility and broad accessibility.
While custom applications are a substantial financial investment, their ability to fully support operational efficiency makes them an attractive option for many businesses.
According to Forbes, one of the biggest advantages of custom-built applications to businesses is their flexibility. They say, “sometimes a one-of-a-kind solution can be deployed anywhere, can allow for more integrations and can offer more independence in terms of design and features.”
Should I use custom-built applications?
When it comes to performance and suitability, nothing can compete with a custom app, for the very reason that it is designed specifically with your business needs in mind. What’s more, custom business applications can be built with the intended environment in mind, lowering the overall cost of integration.
In regards to long-term benefits, custom applications built through a third party provide access to a development team that can enable change at speed, helping you to scale fast and stay ahead of the market.
Unlike SaaS products, you are involved at every step of your application’s development, providing full control over the final product. And, where justified, you can even acquire the IP rights, which can sometimes be classed as a business asset that increases the value of your organisation.
If your goal is a scalable solution that meets business goals and is optimised to be as efficient as possible, then custom-built applications are the way to go.
Drawbacks of custom-built applications
Building an application from scratch is a greater undertaking than simply paying for a SaaS product licence. It also represents a greater expense — at least at the outset. This could quite rightly put off some businesses, especially new startups that don’t yet have the resources to make this work.
Custom-built applications also require a lot of expertise to build, implement, and maintain. Many businesses don’t have this expertise in-house. As a result, they may fail to get the most out of their custom applications, turning a potential investment into a money pit. This is where businesses would benefit from third-party application management if they lack the resources in-house.
