Cloud vs On-Premise Phone Systems: Which Costs Less?

Answer a few quick questions about your business and see how a cloud phone system and an on-premise system compare on upfront cost, monthly cost, growth and upkeep. The comparison is based on how phone systems are priced and installed in Australia.

Over 5 years, cloud is likely to cost less.

On published Australian prices, a new on-premise system for a team your size usually costs more over this period: the phone system, licences and installation up front, then SIP trunks and maintenance every month.

How the two compare for your answers. A longer bar means more cost or effort.

Worth knowing

  • Check your NBN connection type with your internet provider. Both kinds of system make outside calls over it, so it affects call quality either way.
  • Whichever you choose, you can usually keep your existing numbers, including 1300 and 1800 numbers.

The costs

What you pay for with each

An on-premise phone system unit with three desk handsets

On-premise

The phone system (a PBX) sits in your office. You buy it, along with the handsets, and pay for installation up front. After that the ongoing costs are your call plan, usually through SIP trunks over the NBN, and a maintenance plan if you want one. You own the equipment, and it is yours to replace when it ages.

A desk phone, a laptop and a mobile app all connected to one cloud phone system

Cloud

The phone system runs in a provider’s data centre and you pay a monthly fee for each user, which usually includes the system, updates and support. You still buy handsets, or staff use an app on their computer or mobile. Adding someone is usually a matter of adding a user to the plan.

Things to know in Australia

Both now run over the NBN

With the old copper network and ISDN switched off in most areas, an on-premise system makes outside calls over your internet connection too, through SIP trunks. The connection matters whichever you choose.

Keeping your numbers

You can usually take your existing numbers with you, including 1300 and 1800 numbers. Porting times are set by the carriers, so allow some lead time before a move or changeover.

Blackouts and outages

NBN equipment needs mains power. Ask providers about battery backup, and whether calls can divert to mobiles if your internet drops.

000 calls

Your provider records the address of each site so emergency calls can be located. Keep it up to date when staff move or work from home.

Where your data is kept

If call recordings need to stay in Australia, ask cloud providers where their servers are.

Tax

Equipment you buy and a monthly subscription are treated differently at tax time. Your accountant can tell you which suits your business.

Which suits

When each tends to suit

When cloud fits

On published Australian prices, cloud usually costs less for a new system, and the gap is widest for small teams. It also suits staff who work from home or on the road, and businesses with more than one office.

When on-premise fits

On-premise makes the most sense when you already own a system that still works well, because SIP trunking can connect it to the NBN without replacing it. For a larger team buying new, a lower-cost IP system kept for five years or more can come close to cloud, so it is worth getting quotes for both.
