Running a small business means making tough choices every day, and one of the biggest is deciding whether to go with free tools or invest in paid ones.
Free apps can be a lifesaver when budgets are tight, helping you get the basics (like team messaging and video conferencing) covered without adding to your expenses.
Paid apps, on the other hand, can give you access to advanced features, scalability, and dedicated support that free versions just cannot match.
In this article, we’ll share 14 of the best business apps across key categories so you can choose between free tools and paid solutions with confidence.
- Communications apps
- Finance apps
- File storage and sharing apps
- Payment processing apps
- Project management apps
- Customer management apps
- Other marketing apps
🔍 Still relying on a legacy communications platform? Check out this checklist to see what you’re missing out on for better employee and customer experiences.
Communications apps
Whether it is calls, messages, or video conferencing, communication should never be complicated. The right platform brings everything together so your team can focus on their work instead of wasting time and energy juggling multiple apps.
1. RingEX
RingEX is the business communications platform we recommend for small businesses that want to keep everything — calls, messages, video meetings, and even fax — in one place.
Why?
Because using separate tools for each type of communication leads to higher costs, messy workflows, and wasted time switching between apps.
With RingEX, you get a single, powerful platform that simplifies the way you connect with your team and your customers.
Its powerful AI features capture call notes, generate meeting summaries, and translate messages instantly, helping everyone stay focused and aligned.
With industry-leading reliability, enterprise-grade security, and seamless integrations with over 500 popular tools like Salesforce, Google Workspace, and Microsoft Teams, RingEX keeps your operations running smoothly.
And as your business grows, it scales with you — adding users, numbers, and locations is quick and simple.
At just $20 per user/month (annual billing), RingEX puts a powerful, all-in-one communications solution within reach for growing teams.
Free finance apps
If you’re looking for accounting apps or bookkeeping tools, here are some good small business apps:

Which business apps will you use?
Small businesses of all kinds can benefit hugely by switching to free business apps. Given the sheer range of options available, though, it pays to do some in-depth research into the best apps for businesses before making a choice.
Of course, don’t forget that since these apps are free, you’re not locking yourself in. You can afford to try them out and if they don’t work for your business, you can just get rid of them and try another one. But whatever app you choose, your bank account will thank you for it.
In the end, keeping in touch with your team and with your customers is key to the success of any venture, so we’d suggest prioritizing communications first and foremost.
