Customers shouldn’t have to explain their problem more than once. Your team shouldn’t have to log every call manually. And you shouldn’t be losing sales because of clunky communication tools.

But that’s what happens when you use a traditional phone system that isn’t built for the pace of modern work. Your agents waste time on repetitive tasks, customers get frustrated when they have to repeat themselves, your sales process stalls because of manual data entry and delayed communication, and growth slows down fast.

The best business phone system will optimize voice-first communications, provide features that help your agents provide better service and make more sales, and plug into the tools your team already uses.

This comparison guide is built for decision-makers evaluating cloud phone systems. It looks at the top five solutions for growing businesses, and provides key information to help remote and customer-facing teams find a tool that balances price, features, support, and integrations. 

TL;DR

Tips for choosing a business phone system

When considering what to look for in a business phone system, think first about what your team needs the most help with. 

Do agents struggle keeping up with growing call volume and productivity demands? Have to deal with disconnected workflows across phone, SMS, and chat? Lack coaching and performance improvement opportunities due to inaccurate or limited tracking and reporting?

Look for features that boost productivity, automate routine tasks, centralize communication, and integrate with the tools you already use. The right business phone system will free up your team to spend more time making sales and cultivating lasting customer relationships and less time chasing down information or handling avoidable bottlenecks.

Finally, “if you’re looking to choose the right phone system or call center software, my biggest tip is to test the system’s scalability,” emphasizes Oliver Morrisey, Owner and Director of Empower Wills & Estate Lawyers. “Will it grow with your business? Ensure the platform can handle increased call volumes and integrate with other systems as your business evolves.”

Here are a few questions to ask yourself when doing your research.
