According to Forbes, 38% of SMBs (Small and Medium Businesses) go down because they run out of money. That’s because of poor financial management and less capital.

So, while investing in business software sounds like a winning deal, it’s a sinking ship in reality. For one, they have sky-high charges. Two, the more employees you have using them, the higher the cost.

So, what’s the solution? Open-source business applications!

Think about it: you could have a fully functional app or an eCommerce store running within a few hours. And that too without writing a single line of code.

That’s exactly what these tools do. And to top it off, they skip the high licensing fees and can be easily tailored to fit your business. 

It’s no surprise that 78% of businesses are turning to open-source software today.

But which are the top open-source business applications for SMBs and how do you pick the right one? That’s what we’ll learn in today’s post.

Benefits of Open-source Applications for SMBs

Running a small business can be tough on the wallet. That’s where open-source software can be a lifesaver.

Here’s how:

  1. No Big Licensing Bills

Salaries, marketing, and operational costs take a major portion of your budget. Adding pricey software licenses can be a real burden.

With open-source software, you don’t have to pay any licensing fees. You might need to pay for premium features, but it’s a lot cheaper than what you’d pay for proprietary software.

  1. Easy Customization

I believe it should be software that adapts to a business and not the other way around. That’s exactly what you get by going open-source.

You can modify the application to suit your daily operations. You can add more features to it and remove elements that you don’t like without diving deep into coding. Web Apps Generator

  1. Scalability

Proprietary software can become super restrictive as you expand your business. They’ll charge higher and even make it difficult for you to migrate to another solution.

With open-source software, there’s no vendor lock-in at all. In addition, you can easily scale them without any financial strain. 

  1. Added Security and Reliability

It’s a myth that open-source platforms aren’t secure. You’d rather be upgrading your business’ data privacy by switching to an open-source application.

Why? Since the code is publicly available, users quickly identify and address vulnerabilities by applying open-source security best practices—often faster than proprietary software, which can take some time.

Criteria for Choosing the Right Open-Source Application

I’ve jotted down six important considerations before choosing an open-source business application:

  1. Business Needs and Compatibility

Identify the specific challenges that you’re facing. Are you struggling with customer relationships, accounting, or project management?

Understanding your business needs and problems is the first step to choosing the right open-source application for your SMB.

  1. Customization

Not all open-source software is created equal. Thus, customization is a critical factor to consider.

Find out if you can tweak the software to fit your business needs. Or if you can add new features as you grow. Can you modify the interface, automate tasks, or integrate third-party plugins?

Go ahead if the software is flexible enough to adapt to your unique requirements.

  1. Community Support and Documentation

“A strong open-source community is essential for addressing technical challenges, sharing best practices, and understanding how to effectively use the software.”

— [ Ian Nicholls, Founder – AutomobilGarage.com ]

When choosing an open-source software, look for the size of community support and how active it is. A bigger community usually means quicker help and more frequent updates.

Also, check if the software has good documentation. You don’t want to get stuck in technical jargon, especially if dedicated support is not free.

  1. Ease of Use

Non-IT SMBs usually don’t have tech-savvy teams. Thus, it is necessary to pick software that’s user-friendly and has a minimal learning curve.

For example, prefer drag-and-drop and no-code functionality to quickly customize the software. Also, see if the application is responsive to different devices for maximum efficiency.

  1. Implementation and Maintenance Costs

While most open-source software is free, there can be additional costs involved. For example, implementation charges, hosting fees, premium features, enterprise solutions, dedicated support, etc.

So, choose wisely.

  1. Security Features

Open-source software can be as secure as proprietary tools. But it’s best to evaluate and verify their security measures.

Look for features like data encryptions, two-factor authentication, and RBAC. Most importantly, choose platforms that are compliant with global information security standards.

Conclusion

Open-source business applications are the MVPs of this digital transformation era. These tools not only save you money but also give SMBs room to grow without any limitations.

Choosing open-source software brings innovation, flexibility, and efficiency. It’s ideal for businesses aiming to succeed without high operational costs.
