For small businesses, the typical costs associated with a VoIP phone system can be divided into setup, ongoing service, and any optional extras. Initial setup costs are often lower than with traditional phone systems, because VoIP uses your existing data network rather than requiring extensive new cabling. However, you may still need to budget for compatible IP handsets, headsets, routers, power supplies, and potentially an upgrade to your broadband connection to ensure sufficient bandwidth and reliability. Some providers charge a one-off installation or configuration fee, while others include this within a bundled package. If you are moving from an on-premise system, there may also be costs for number porting and any necessary integration with your current IT environment.
Ongoing costs usually take the form of monthly per-user or per-line licences, which cover access to the VoIP platform, core calling features, and standard support. These charges typically include internal calls and a bundle of minutes to UK landlines and mobiles, with additional call charges for out-of-bundle usage or international destinations. You may also pay extra for advanced features such as call recording, call centre functionality, CRM integration, or premium support levels. When comparing options, it is important to consider the total cost of ownership over several years, including hardware refresh cycles, connectivity, and support, rather than focusing solely on the headline monthly fee.
The main recurring cost is the monthly service charge. This is often priced per user or per simultaneous call, and may be offered on a tiered basis, with higher tiers including more features such as auto-attendants, voicemail-to-email, or video conferencing. Some tariffs are fully inclusive, while others separate line rental, call bundles, and feature licences.
Hardware costs vary depending on how your staff work. Desk-based teams may require dedicated IP handsets, while more mobile or hybrid workers can often operate using softphone applications on laptops and mobiles, reducing hardware spend. Quality headsets and reliable routers or switches are worth budgeting for, as they directly affect call quality and user experience.
Connectivity and support also form a significant part of VoIP costs. A robust business broadband or dedicated connectivity service may be necessary, particularly for larger teams or heavy call volumes. Support can be included in the monthly fee or charged as a separate maintenance contract, covering monitoring, remote changes, and on-site engineering when required.
