The short answer
Business phone system quotes rarely arrive in a comparable format, so put every quote into one comparison grid covering users, handsets, calls, features, setup and term, then work out the effective monthly cost over the full contract instead of trusting the headline price. Ask every provider for its Critical Information Summary to fill in anything a quote leaves out.

You asked three providers for business phone system quotes, and you got three documents that look nothing alike. One leads with a monthly price per user. One bundles handsets into a single figure. One lists twenty line items and a setup fee. None of them is lying, and none of them is directly comparable with the others.
This post is about making them comparable. It covers the grid to put every quote into, how to work out the real cost over the term, the gaps to look for, and the questions to send back before you decide.
Why are business phone system quotes so hard to compare?
Because each provider packages the same parts differently. A phone system quote combines at least six things, including user licences, handsets, call costs, features, setup and support, and every provider draws the lines between them in a different place.
The result is that two quotes with the same monthly figure can describe very different systems. One might include handsets, porting and unlimited local calls. The other might rent handsets separately, charge per call, and put call recording on an add-on. The monthly number hides all of that.
The grid: put every quote in the same format
Build one table, with a column per provider, and move every line of every quote into it. Where a quote says nothing, write the question into the cell rather than leaving it blank or assuming it is free.
| Line | What to record | Question if the quote is silent |
|---|---|---|
| Users | How many user licences, and what each includes | Is a licence per person, per handset, or per line? |
| Handsets | How many, which category (desk, cordless, conference), bought or rented | Are handsets included, rented, or bought outright, and who owns them at the end? |
| Numbers | Which numbers move across, and any new ones | Is porting your existing numbers included? |
| Calls | What is included, and the rates beyond it | Which call types are included, and what does everything else cost? |
| Features | Queues, recording, voicemail to email, reporting, apps | Which features are in the base price and which are add-ons? |
| Setup | Installation, configuration, cabling, training | Is setup a one-off charge, and does it include any cabling? |
| Support | Hours, channels, response commitment | Where is support based, and what are its hours? |
| Term | Minimum length and monthly commitment | How long is the minimum term? |
Two rules that keep the grid honest
Compare the same number of users and handsets across every column, even if you have to ask a provider to requote. And never fill a gap with your own assumption. A blank cell is a question for the provider.
Handset choice is its own decision, and the categories are covered in the guide to choosing business phone handsets. For the grid, what matters is that every column quotes the same kind and number of devices.
How do you work out the real cost of a phone system quote?
Add every cost over the full minimum term and divide by the number of months. That gives a true monthly figure you can compare across quotes, even when their structures are completely different.
The calculation for each quote:
Step 3 is where quotes most often reorder themselves. A plan with a lower monthly price and per-call charges can end up more expensive than a higher-priced plan with calls included, for a business that is on the phone all day. Your existing bill is the best guide to your pattern, and the guide to reading a business phone bill shows which lines to pull out.

What is a Critical Information Summary, and why ask for one?
It is a short standard document that every telco must provide for each plan, and it is the quickest way to check a quote. The ACMA explains that all telcos selling telecommunications products must provide a Critical Information Summary, which sets out what is included, how long the minimum contract lasts and what to do if you have a complaint. For postpaid services the telco must provide it before you buy, with some exceptions.
Ask every provider for the summary behind its quote. It helps in two ways:
If a quote cannot be matched to a summary, ask which plan it is based on. A quote built on no identifiable plan is harder to hold anyone to later.
Where do quotes usually hide the differences?
In the parts that do not show up in the monthly figure. When two quotes look close, the difference is almost always in one of these:
None of these is a trick. They are simply the places where providers make different choices, and the grid is how you see them side by side.
What questions should you send back before you decide?
Send each provider its own list of blanks from the grid, plus anything that does not add up, as specific written questions. Good questions look like this:
How each provider answers is useful in itself. A clear, written answer within a day or two tells you something about how the relationship will run after you sign.
Comparing business phone system quotes to make a decision
Once every quote is in the grid, costed over its full term and matched to its Critical Information Summary, the decision usually gets much simpler. The cheapest effective monthly cost is one input. What is included, what support looks like and how clearly the provider answered your questions are the others.
Contract terms themselves, including exit costs and what happens at the end of the term, deserve their own read-through before you sign. Treat the quote comparison as the step that narrows the field, and the contract review as the step that confirms the winner.
