Bidline · off-market bid rounds for licensed Australian agents · pre-launch · en-AU
For licensed selling agents · every state and territory
Run your next off-market property as a round, not sixty phone calls.
You pick who is invited and what they can see. Only buyers with verified finance can bid, and they bid as paddle numbers. What follows carries the platform’s own visibility settings: change one and the buyer’s side changes with it.

Public listing card: bidding underway
Example round, built from the platform's own settings. No round has run on Bidline yet.
The first thing every agent says
No. We want you to keep it.
Your off-market list is the business, and we know exactly what we would be asking for. We are not asking for it.
You invite the buyers. Bidline does not market to them, does not put them in front of another agent, and does not sell enquiries to anyone. The only messages Bidline sends a bidder are about the round they are already standing in: outbid, closing, closed. Nothing else, ever.
A buyer on your round cannot see your vendor, cannot see the street address until you accept them, and cannot be lifted off the platform by the agent down the road.
What this replaces is not your rolodex. It is the sixty calls, the WhatsApp thread that disappears when the phone does, and the offer you relayed from memory at nine at night.
- Anyone with the link
- The listing card only: suburb, price guide and the round’s countdown. No photos, and the address stays greyed.
- A buyer who has registered
- The full gallery and any video tour. They can watch the listing and register interest. They still cannot bid.
- A buyer with verified finance
- A banded tier that lets them bid, and the documents you have gated. The exact street address goes to the bidder you accept, and only to them.
- You set the audience for each round: invited buyers only, or everyone with verified finance in the region you choose.
- Bidders compete as paddle numbers. A name does not appear at any point in a round.
- Bidline does not sell, share or resell buyer contacts. That is clause 5a of the agent agreement, which is a draft until counsel signs it, and you can read it now. Read the agent agreement
The vendor’s question, and yours
One agent’s rolodex is what costs the vendor. Not going off-market.
PropTrack research has off-market sales landing about 4.3% under comparable on-market listings, which is roughly A$60,000 on a Sydney median. Your vendor will read that in a property column and put it to you, and they are not wrong to.
The gap is not privacy. It is depth. A campaign that reaches the sixty buyers one agent can phone in a week finds a smaller top bid than one that reaches every qualified buyer at once with the number to beat on the screen. That is the whole argument for running it as a round, and it is the argument you take into the listing presentation.
We cannot prove we close that gap. Nothing has settled through Bidline yet, and a claim we cannot measure is not worth making to someone who sells property for a living. What we can do is give you the record to argue it with. At the close you have who bid, what they bid, and what terms each one carried.
About 100,000 Australian residential sales a year go off-market — roughly 1 in 5 of all residential transactions.
× a national average sale price near A$800,000
= something in the order of A$80 billion a year, moving with no structured process behind it.

The fair question
Right now, fewer than you would like. That is the offer.
Bidline is pre-launch. Telling you otherwise is the fastest way to lose you three weeks from now.
Here is what is true today. A buyer cannot bid until a pre-approval or proof of funds has been reviewed by a person and banded. The band and its expiry travel with the bid, so you are not discovering a finance problem a fortnight into a deal, and the platform refuses a bid above the band.
Here is what is true about the timing. The buy side is being built around the stock the first hundred agents bring. Agents who are early shape that pool instead of inheriting it. In two years it is somebody else’s advantage.

What it costs you in time
One listing, then the round runs itself.
Publish the listing.
Address, the one price figure from your signed agency agreement, up to eight photos, and which one is the street. Bidline derives the advertised guide from your figure and shows it back for you to confirm before anything publishes. It refuses a range wider than 10% above the low, because NSW’s Property and Stock Agents Act 2002 s73(b) does.
Open the round.
Pick the format, set the close, choose what bidders can see. That is the panel at the top of this page.
Then it runs without you.
Bids land with their terms attached, in order, timestamped. A bid inside the last five minutes pushes the close out five more, up to twelve times, so an hour of extensions at most — nobody takes a property off your vendor with a fast thumb at 5:59. Bidline sends an alert when a bid lands on one of your rounds, and the ladder on the round is the record either way.
Four ways to run it, and one of them is not a round at all.
- Open round
- The ladder runs live under the five-minute rule, and you choose how much of it bidders see: the full ladder, the leading bid only, or none of it.
- Sealed round
- Nobody sees the field — no ladder, no bidder count, no position — and you open the bids together at the close.
- Expression of interest
- Buyers register interest and terms against a deadline, and you negotiate from there. Built for development sites, where capability matters as much as price.
- Contact agent
- No bid round at all. Buyers with verified finance approach you directly, and every approach is logged.
The record
Every round closes with something you can hand over.
Every bid is written into a chain, and each one carries a SHA-256 hash of the bid before it. Change an amount after the fact and every hash downstream of it stops agreeing, visibly, to anyone who checks: a vendor, a principal, or Fair Trading.
A bid cannot be edited and it cannot be withdrawn. What the ladder showed at 4:35 pm AEST is what it shows in two years.
Round events — the open, the extensions, the visibility settings, the close — are logged alongside the chain and retained to meet Australian record-keeping obligations. There is no number of years on this page. The retention period is with our lawyers, and we would rather carry the gap than a figure we made up.
Try altering a record.
Three bids, three hashes, each one built on the record before it.

Terms
Bidline runs the process. It is not in your deal.
Not an agreement to buy
A bid on Bidline is an expression of intent. Sale agreements are signed off Bidline, under your state’s ordinary conveyancing process, through the solicitors who would have done it anyway.- Price guides are bounded by law, in code
- Your agency figure goes in once. Bidline derives the advertised guide from it and refuses a range more than 10% above the low, per NSW Property and Stock Agents Act 2002 s73(b). You confirm the guide before it publishes, and what you confirmed is stored with the disclosure wording you were shown.
- No money moves through Bidline
- No deposits, no settlement funds, no trust account, and no payment surface anywhere in the product.
- Your licence is checked by a person
- Licence number, state and expiry are recorded at sign-up and reviewed before your first listing publishes. It is a queue with people in it, not an instant tick.
- The buyer’s finance stays private
- You see a band and an expiry date. Not the lender, not the document, not the exact approved figure. Neither does your vendor.
Who pays what.
What each party can do on Bidline, what we check before they can do it, and what it costs them.
Selling agent
- What they can do
- Publish listings, run rounds, set the visibility, close and accept
- What we check
- Licence number, state and expiry
- What it costs
- A$0 for the founding 100, locked to your licence. A$99 a month after that.
Buyer’s agent
- What they can do
- Bid for client mandates against each client’s finance band
- What we check
- Licence, plus a signed client mandate
- What it costs
- A$0 through Year 1. A$199 a month after that.
Pre-approved buyer
- What they can do
- Bid directly, under the same rules as the professionals
- What we check
- A pre-approval or proof of funds, reviewed and banded
- What it costs
- Free, and it stays free.
One more number, because leaving it off a page like this would be the tell. From Year 3, Bidline takes 0.25 to 0.5% of a completed sale, capped at A$3,000 and split between the sides. Nothing is taken on a listing, a round, or a bid that does not complete. Founding agents keep the A$0 subscription for the life of the account; the success fee is separate and applies to everyone.

Disclosure
What Bidline is not.
- Not a portal.
- Bidline does not advertise property to the public and has no consumer audience to sell you.
- Not connected to realestate.com.au, REA Group or Domain.
- Not affiliated, not endorsed, not built from anything of theirs.
- Not a party to your sale.
- Not the agent, not the vendor, not a licensee in any transaction.
- Not holding anyone’s money, at any point.
- There is no trust account and no payment integration in the system.
- Not carrying a transaction record yet.
- The platform is built and running on staging. No round has settled through it, and anyone who tells you different about a pre-launch product is selling you something.
- Not finished on the retention period.
- It is with counsel. Until that is settled, this site states the obligation and does not print a number.
Founding 100
One listing. Judged on what your vendor gets at the close.
That is the whole ask. One off-market property you were going to run over the phone anyway, run as a round instead. If it does not beat the phone, you have lost a fortnight and we have lost an argument.
The first 100 selling agents pay A$0 for as long as they use it. Not free for a year — free for good, locked to your licence in writing. Every application is read by a person, not a form filter.
Or just reply to the text that brought you here. A person reads those.
Not a selling agent? Buyer’s agents bid on client mandates and pre-approved buyers bid directly. Both are free right now. For buyer’s agents · For pre-approved buyers
