TL;DR
The demo is the easy part. Everything in it works, because the person showing it configured it that morning. What you are deciding when you sign for company phone systems is a set of commitments that run for years: what you pay, what you can change, what you can leave, and who holds the numbers your customers already have.
This post is the checklist to work through before that signature, written as questions to put to any provider, including the one you already like. If you are still choosing between system types rather than reading a contract, start with the buying guide and come back here.

What do company phone systems actually commit you to?
Company phone systems are usually sold as two agreements at once, and separating them is the single most useful thing you can do before signing either. There is a service agreement for the calling platform and the numbers, and there is often a separate arrangement for the hardware.
Those two can have different lengths, different exit terms and different owners. A three-year hardware rental sitting underneath a service you can leave in twelve months is not the flexible deal it appears to be.
Equipment rental is a real commercial model in this market rather than a hypothetical: NexGen’s own finance FAQ references an equipment rental agreement paid by monthly direct debit. So ask which of the two documents each line on the quote belongs to, and ask for both documents rather than a summary of them.
Worth noting before you read a word of either: under the TCP Code, providers must give you a Critical Information Summary for a plan, and you have a right to information about the service that is clear, accurate and not misleading. If a provider cannot produce a summary of what you are buying, that is information in itself. The ACMA has also said it will replace the industry-written code with a directly enforceable standard carrying stronger protections, so the floor here is rising rather than falling.
How long should the contract run?
As long as you can confidently predict your headcount, and no longer. For most small businesses that is a shorter horizon than the contract on offer, which is why the term is the first thing to negotiate rather than the last.
The question behind the question is not really “how many years”. It is what happens in those years when your business changes:
That last one is worth being firm about. The ACCC treats an unreasonable ability to prevent a small business from exiting a contract as a hallmark of unfairness, alongside a unilateral right to change the terms. Since 9 November 2023, proposing or relying on such terms is banned rather than merely unenforceable, with new penalties attached, and the protections now reach businesses with fewer than 100 employees.
Who owns your phone number if you leave?
Nobody sells you a number outright, but the right to take it with you is set by regulation rather than by your provider’s goodwill. This is the most commonly misunderstood item on the list, and the most reassuring once you understand it.
Under ACMA’s rules your current telco must transfer your number when you or the incoming telco ask. The porting timeframes come from the Local Number Portability Code: for a single local number, most ports are expected to complete inside 8 to 15 business days, while complex multi-number ports can run to around 30 days. A mobile number is usually hours.
Two practical cautions, because “portable” is not the same as “effortless”:
The mechanics of the transfer itself, and what to have ready for the port window, sit in number porting works for Australian businesses.
Why does cost come up first in almost every enquiry?
Because cost and value is one of the reasons we hear most often for a business going looking in the first place. The pattern owners describe is consistent: locked into an ageing system that is expensive to maintain, paying for multiple services, legacy hardware, or features nobody uses any more.
Which sets up the trap this post is about. A buyer who arrives motivated by cost tends to compare the monthly figure and stop there, and the monthly figure is the part of a phone agreement least likely to be where the money goes wrong. Term length, exit terms, what happens to the handsets and what the bill looks like after any introductory period all move the real number, and none of them appear in a quote’s headline. Work the checklist below before you compare prices, not after.
The checklist to work through before you sign
Paste it into the email you send the provider. The value is in getting the answers in writing, because a written answer that turns out to be wrong is a very different conversation from a remembered one.
| The question to ask | What a good answer sounds like | What should worry you |
|---|---|---|
| How long is the term, and when exactly does it start? | A stated number of months, starting on a defined event such as service activation | “Standard term”, or a start date nobody can name |
| What does it cost to exit early? | A stated formula you can calculate yourself | A figure that can only be worked out by the provider on request |
| Does the agreement auto-renew, and what notice stops it? | Renewal terms and a notice period stated in the contract, in weeks | Automatic rollover with a long or unstated notice window |
| Can I add and remove seats mid-term? | Both directions covered, with any limit named | Adding is easy, removing is “not something we normally do” |
| Does adding a seat restart the term? | No, or a clear statement of what does restart it | Vagueness here. This is a common trap |
| Who holds the numbers, and can you block a port? | Confirmation the numbers are portable on request | Any suggestion the numbers belong to the provider |
| Is the hardware rented, financed or purchased? | A clear statement, with the document that governs it | Hardware bundled invisibly into a monthly figure |
| What happens to the handsets at the end of the term? | Return, buy out at a stated basis, or keep | “We’ll sort that out at the time” |
| What does support cover, and what is billed extra? | Named inclusions, named exclusions, stated hours | “Full support” with no definition |
| Where is the support team located? | A direct answer | An evasive one |
| What is the total monthly figure in month 13? | The same as month one, or a stated change | A promotional rate with no stated end |
| What is not in this quote? | A short honest list | “Nothing” |
What happens to the handsets at the end of the term?
One of three things, and you should know which before you sign rather than discovering it in the final invoice. The handsets are either returned, bought out, or already yours.
Each carries a consequence worth thinking about now. If they are returned, the return date and the replacement date have to be planned together, or you have no working phones on day one of whatever comes next. If they are bought out, ask what the buyout is based on. If they are already yours, ask whether they will work on another provider’s platform, because a handset locked to one platform is a rental you paid for outright.
What does the bill look like in month 13?
The same as month one, unless someone tells you otherwise in writing. That is the standard to hold a quote to, and the reason to ask the question in exactly those words.
Three things commonly change after the first year: a promotional rate ends, an annual price review clause is applied, or usage that was included turns out to have been capped. Ask which of those exist in your agreement. Then ask for a worked example of the twelfth and thirteenth invoices side by side.
Billing is not a marginal concern. The Telecommunications Industry Ombudsman received 57,592 complaints in 2024-25, with service and equipment fees the second largest issue at 20,564, and small business accounting for around 11 per cent of the total. If you want the cost side worked through properly before you get to a contract, the system cost breakdown covers what actually drives the figure.
Where company phone systems contracts go wrong
You are not on your own when one does, and that is worth knowing before you sign rather than after. Complain to the provider first, in writing, and keep the reference number.
If that does not resolve it, the Telecommunications Industry Ombudsman is free and open to small business as well as residential customers. Terms that lock you in unreasonably or let a provider change the deal unilaterally may also be unenforceable under the unfair contract terms regime, which applies to standard form contracts of the kind almost every phone system is sold on. A contract you signed is not automatically a contract that binds you to everything printed in it.
Before you sign
Work the table above with whoever you are close to signing with. A provider who answers all twelve questions plainly has told you something more useful than any feature list, and one who cannot answer them has told you something too.
If you want clear answers to these questions rather than a brochure, NexGen has been doing this for Australian businesses for 17 years, with 7,500+ businesses served, ISO 27001 Certified and an Australian-based support team. Standard onboarding is 7 business days, so the timeline from decision to working phones is short enough to plan around. Start with a small business system quote.
