For small and medium-sized enterprises, 3CX phone systems are typically priced using a software-based model rather than traditional per-handset licensing. The core cost is usually the 3CX licence itself, which is based on the maximum number of simultaneous calls rather than the total number of users or extensions. This makes it more predictable and scalable for growing businesses, as you can add users without immediately increasing your licence tier. Pricing is commonly structured in bands (for example, 4, 8, 16, 32 simultaneous calls and upwards), with higher tiers costing more but offering a lower effective cost per user. On top of the software licence, there may be charges for hosting, SIP trunks, and any optional add-ons or integrations your organisation requires.
Most SMEs encounter three main pricing approaches: on-premise licences with a one-off or annual fee; cloud-hosted 3CX instances with a recurring subscription; and fully managed packages that bundle the 3CX licence, hosting, call minutes, and support into a single monthly cost per system or per user. On-premise deployments may be more economical if you already have suitable server hardware and IT expertise, but you will still need to budget for SIP trunk rental and ongoing support. Cloud-hosted and managed models, by contrast, shift costs to a predictable monthly operating expense, often including updates, monitoring, and local engineering assistance. The most suitable model depends on your call volumes, internal IT capabilities, and preference for capital versus operational expenditure.
The first common pricing model is a standalone 3CX software licence, usually billed annually and sized by simultaneous calls. SMEs purchase the licence, install it on their own hardware or virtual server, and then add SIP trunks and handsets separately. This can be cost-effective where there is existing infrastructure and internal support.
The second model is hosted 3CX, where the system runs in the cloud. Here, pricing typically combines the 3CX licence with a hosting fee, often per month or per year. This reduces on-site hardware requirements and shifts maintenance, backups, and updates to a specialist provider.
The third model is a fully managed or bundled solution. This usually includes the 3CX licence, cloud hosting, SIP trunks, call packages, and ongoing support for a fixed monthly charge. For SMEs wanting predictable costs and minimal administration, this model often provides the clearest value, especially when paired with local engineering and responsive helpdesk support.
