3CX Pricing

Save Up to 80% On Your Business Telecoms With 3CX

With 3CX’s simultaneous call pricing model you can save thousands on your business phone system costs.

Save Money

By reducing your current costs by up to 80%.

Save Time

With a phone system you can rely on.

Save The Day

With a phone system everyone will love.

Your business phone system shouldn’t cost ‘that’ much!


  • High monthly service costs for every employee (per seat)

  • Expensive national and international call costs every month

  • Additional costs for each premium feature you need to use

  • And yet more monthly costs for phone line and number rental

And that leads to constantly rising costs as your business grows.

It doesn’t need to be that way.

How many simultaneous calls do you need?

We can work with you to determine what’s best for your business. However, as a general rule of thumb, 1 simultaneous call per 3-4 extensions is sufficient, i.e. a company with 50 extensions would need a 16 sim. call licence.

Is the free licence actually free?

Yes. Annual Standard 3CX licences for 4 or 8 simaltaneous calls are free licence.  

That inlcudes unlimited extensions, iOS & Android apps and auto-provisioning.

To make inbound and outbound calls you will need to BYO or choose own SIP trunk and numbers. 

You can DIY setup, or set-up and support can be purchased. 

Upgrade at any point by paying the price difference and without reinstalling.

What are simultaneous calls?

Simultaneous calls are calls made concurrently at a given time.

Most businesses find they need the ability to make 1 simultaneous calls per 3-4 extensions.

Can I upgrade later?

Yes. You can upgrade your subscription at any point in time by just paying the difference for the remaining period.

What is a 3CX reseller?

A 3CX reseller is company authorised to provide 3CX products. 3CX does not
directly sell its own licences; they must be bought through a 3CX reseller.

We are a Platinum 3CX Partner and have been working with 3CX for 15 years.

Does my licence need to be renewed annually?

Yes. 3CX licences require renewal every year. 

If your licence expires you will automatically be downgraded to an 8SC annual standard licence.
An 8SC licence is a standard software as a service licence without the services included in the annual subscription. 
Where can I get the 3CX Software?

You can download the latest version of 3CX from the 3CX website. You will find versions for Windows and Linux (Debian) as well as the 3CX SBC. There are also links to download the softphone applictation for Windows, Android and iOS. The aplications are all subject to the 3CX End User Licence Agreement.

Where can I get the 3CX user Manaul?

3CX publish an end user manaul on their website that will talk you though the Webclient, the Applications, your Deskphone, Voicemail and Conferencing. There is also an administrators guide that will talk you through how to install 3CX either on premise or in the cloud. The guide covers Installation, creating Users, SIP Trunks, IVR’s/Call centres and System Manangement.

3CX Pricing Guide

3CX pricing is based on the number of simultaneous calls your company needs to make and not the number of extensions or users. This includes internal and external calls. This makes 3CX pricing much more competitive than other phone systems that charge per user.

1 simultaneous call per 3-4 people works best for most businesses. For example, if you have 50 people, you’ll need a 16 SC license. If you’re unsure, buy your license using this ratio and you can easily upgrade it later if needed.

How do I get my license?

Your 3CX license is sent to you via email once your order has completed.

As soon as your order is processed, you’ll receive an order confirmation email within a few minutes with you license key and tax invoice attached. 

Need to renew a license key? 

If you already have a 3CX License key just select the same license size and type as your existing key and add you existing key in the notes at the checkout. Your licence key will be checked and renewed automatically, and you’ll get a confirmation email within a few minutes of placing your order.
