Phone systems for small businesses

In this 2023 buyer’s guide for business phone systems for small businesses, we will identify the features you should look for, how much these systems cost, the best virtual phone providers in the market and what you need to know about them.

Why do you need a business phone system?

A small business needs a business phone system to provide an effective communication tool for the team, customers and clients. Having a number specifically for customers, clients and colleagues also makes you look professional and credible.

Getting the right phone system for small businesses will also give you access to features such as call forwarding, voicemail, auto-attendant, virtual faxing, music on hold and conferencing. All of these features can help a small business stay organised and increase its customer satisfaction.

A business phone system elevates customer experiences

Put together, this is the most important benefit of phone systems for small businesses: Collectively, all the features in phone systems for small businesses enable you to provide unified and seamless customer experiences. And that’s crucial.

A message from your business can reach customers and potential clients in several ways. Some may see it on Google’s search results whereas others may find you through your Instagram Reels. If they’re interested in your service or if they have a complaint or query, they may choose to contact you across these platforms.

But a business phone system is the most immediate and fastest way for anyone to reach a business. If they’re looking for a solution, sending an email or talking to a chatbot on a website may not provide instant relief. A phone call or text is more direct and personal.

Whether it’s a potential user or an aggrieved customer, a phone call is a crucial part of their customer experience. With phone systems for small businesses, you can have a centralised hub for all customer and client interactions.

So, how did it all begin? Understanding the evolution of phone systems for small businesses will help us place the technology in context and help you choose the right solution.

A potted history of business phone systems

Put simply, business phones evolved from desk versions to mobile phones to VoIP (Voice over Internet Protocol).

PBX phone systems for small businesses

PBX systems allowed organisations to have their own private phone system that could connect multiple lines and users and route and manage incoming and outgoing calls. This allowed for features such as automatic call routing, voicemail, call recording and more.

At its core, PBX is a desk phone to handle multiple calls at the same time and direct them to the right user. You can only access and use the phone if you’re at the location. Decades ago, this was no problem because businesses mostly operated from their sites.

Should you choose a PBX business phone system? It’s expensive to install and maintain and requires trained staff. Plus, it’s not a mobile system and therefore, not conducive to remote work.

Mobile phone systems for small businesses

The next step in the evolution of phone systems for small businesses was the mobile phone. Now, you could be connected from anywhere as long as you had cellular network coverage. Business owners and professionals appreciate the convenience of being able to access their phone system from any location, including remote offices and job sites.

Mobile phones have far more features than traditional landline systems, such as call forwarding, conference calling and integration with apps. They can also provide enhanced security for businesses that handle sensitive data or information.

Should you choose a mobile phone as your business phone? You could but what you want is a specific number for work-related calls and messages to protect your personal number. Plus, you can always combine mobile phones with an advanced option.

VoIP phone systems for small businesses

The most advanced of all business phone systems is VoIP. This is when business phones truly entered the digital era. VoIP uses the internet to connect callers and is, therefore, device and location-neutral. It delivers all the advantages of a mobile phone and much more because it’s an application with several communication tools.

A VoIP business phone system doesn’t require any significant initial investment and is easy to set up. You can use these phones wherever you have an internet connection. Moreover, VoIP business phones give you a unified communications system that combines instant messaging, analytics, multi-media sharing and real-time collaboration.

Should you choose a VoIP system as your business phone? Among phone systems for small businesses, VoIP is the most cost-effective, remote-friendly and feature-rich option. If you’re a small business owner, it will save you money, make you more agile and give you enterprise-grade tools.

How much does a small business phone system cost?

The cost of a business phone system will depend on its size, the number of users, its features and the kind of system you want. This analysis of business phone systems will help you choose the one that suits your budget.


PBX phone systems require considerable initial investments and upkeep. If you need around six handsets for two phone lines, a PBX system can cost you around £160. If your business needs 16 lines with around 64 handsets, that cost will be more than £900.

The cost of on-premise PBX systems will be higher since the business has to invest in infrastructure. While it would vary based on the size, lines and features, for a small business, a PBX business phone system can easily cost upwards of £500. For medium and large enterprises, this could be around £10,000.

PBX cost implications for small businesses

Among business phone systems, you can opt for PBX if:

  • You’re a medium or large enterprise

  • Your business is stationed in a location

  • Your team answers thousands of calls a day

  • You have more than 10 stationary customer support agents

  • You have the budget for initial investments and maintenance

  • You have access to trained personnel for upgrades

You shouldn’t choose PBX as a business phone system if:

  • You’re a small business owner

  • You have a remote or hybrid team

  • You have fewer than 10 employees

  • You spend a lot of time on-site and away from the office

  • You don’t want to make investments in hardware and their maintenance

  • You don’t have access to trained staff for the system’s upkeep

Mobile phones

The cost of using a mobile phone as a phone system for small businesses depends on the device, plan, usage and number of users. There’s a greater variety of smartphones and you can choose one that suits your needs. Popular handsets can cost more than £998 and could go up to £1,468.

If you opt for a SIM-only deal, you may have to pay an additional £105 per year on average. Choosing a contract could lower the annual bill to around £1,162. If you’re a small business owner, therefore, it makes sense to choose contracts over individual handsets.

Mobile phones cost implications for small businesses

You can use a mobile phone for business if:

  • You have a limited business operation

  • You don’t have to answer more than five calls a day

  • You have fewer than three clients

  • You don’t get calls during off-hours

  • You don’t have to buy devices for team members

  • You only need the phone for calls and texts

  • You have a dedicated customer support division with a specific number

You should look beyond mobile phones if:

  • You want to protect your personal number

  • You want to share your business number on your website and social media

  • You have more than three clients

  • You expect multiple calls during the day and even during off-hours

  • You want to separate your work and personal lives

  • You want tools such as call forwarding, group broadcast and auto-reply

  • You want a complete phone system rather than a business number


If you’re searching for phone systems for small businesses in 2023, a smarter and more cost-effective option is VoIP. In VoIP, if you choose a hosted configuration, you will have to pay around £250 on average for installation. If you select a cloud-based system, the costs will be significantly lower since you don’t have to pay for any devices or their maintenance.

Since it’s an application - the reason these VoIP phones are also called cloud phones or softphones - you can save a lot both initially and in your monthly costs. You will be subscribing to a service and even top-rated ones would only cost you £10 per month per user. The monthly charges are particularly low for long-distance or international calls.

VoIP cost implications for small businesses

You should choose VoIP as your business phone if:

  • You’re a small business owner, freelancer, service professional or early-stage startup

  • You want an additional number dedicated to work-related calls and messages

  • You don’t want to unnecessarily spend on devices, hardware, or their maintenance

  • You want to reduce your monthly phone bills

  • You want to easily onboard employees

  • You have a remote or hybrid team

  • You want additional tools including auto-reply, broadcast SMS, voicemail and analytics

  • You want advanced texting capabilities

  • You need a number for WhatsApp Business to engage with your customers

  • You make several long-distance or international calls

  • You want a scalable phone system that can grow with your business

  • You want your team members to share a number to improve customer service

VoIP is not your ideal option if:

  • You have an unreliable internet connection

  • Your business is bound to a location

  • You don’t expect many customer calls or lead-related queries

  • You won’t be using your number in your marketing campaigns

  • You don’t require additional business tools

  • You’re comfortable with investments in hardware

9 key features of virtual business phone systems

The biggest advantage of a virtual phone is that you don’t have to buy an additional device. This alone saves you more than a thousand pounds a year. The savings are significantly higher if you were to otherwise buy phones for your employees or reimburse their purchases

2. Virtual numbers can work on multiple devices
