Quick Answer: When businesses research business phone system cost in Australia, they often find confusing price ranges. At Smart Phone Systems, a fully managed hosted extension costs a flat $40 +GST per month. That single rate includes number porting, onboarding, custom greetings, and call flow design. It also covers ongoing support and local, national and mobile outbound calls. The first month is free and there is no lock-in contract. There are no separate setup fees and no minimum number of extensions.
What’s Actually Included in Our Rate
A lot of confusion around business phone system costs comes from providers who advertise a low headline price. They then add charges for the things that make a system usable. These extras typically include porting your existing number and setting up call flows and greetings. They also cover onboarding your team and ongoing support when something needs changing.
Our $40 +GST per extension rolls all of that into one flat monthly rate. The only costs excluded are calls to 13, 1300, and international numbers. These are billed at standard rates — the same as almost every provider in the market.
Why a Flat Rate Is Easier to Budget For
When you’re comparing phone system providers, it’s worth asking exactly what a quoted price includes before comparing it to ours. A lower headline number can easily cost more once fees for porting, onboarding or support are added back in. See our pricing page for the full breakdown of what’s included as standard.
Hardware: Buy or Rent?
Every extension includes free access to the mobile softphone app. You don’t need a desk phone at all unless you want one. If you’d like physical handsets, you can buy outright or ask about renting.
Rental is a great solution if you’d rather avoid the upfront cost, get in touch for current rental rates.
One-Off and Setup Costs
With Smart Phone Systems, there is no setup cost, and the first month is free for new customers. Not every provider works this way. Ask any provider you’re comparing for a full written breakdown of one-off costs before signing up.
What Affects Business Phone System Cost in Australia
Our pricing is a flat rate per extension with no minimum. Your monthly cost is simply the number of extensions your team needs, multiplied by $40 +GST. The only other variable is hardware — only if you prefer physical desk phones over the included mobile app.
How to Budget for a Switch
For a 5-person team, that’s 5 extensions at $40 +GST, or $200 +GST per month all-inclusive, with the first month free. Add hardware only if you want physical desk phones rather than the included mobile app.
It’s also worth remembering that a hosted system typically replaces other existing costs. A maintenance contract on an old on-site PBX is a common example. Happy to talk through your specific numbers, just get in touch and we’ll put together a real quote, not a generic range.
Frequently Asked Questions
Is a hosted phone system cheaper than a traditional landline system?
In most cases, yes. Business phone system costs in Australia are typically lower with a hosted solution, particularly once you factor in maintaining or replacing ageing hardware. For general guidance on comparing phone plans, the ACCC provides useful consumer advice on what to look out for.
Are there hidden costs I should watch for?
With other providers, the most common hidden costs are porting fees, onboarding charges, and mobile call rates not included in the plan. With Smart Phone Systems, porting, onboarding and mobile calls are all included in the flat monthly rate, with only 13, 1300 and international calls charged separately.
Can I get a fixed monthly price with no surprises?
Yes. Our pricing is a single flat rate per extension, so your monthly cost is predictable from day one.
Do I need to sign a long contract?
No. We offer month-to-month terms with no lock-in contract and no minimum number of extensions. See our pricing page or get in touch to discuss your first free month.
