Tender software in Australia, compared on what each one publishes

Four of these are not competing with each other

The phrase “tender software” collapses four genuinely different products. Australian Tenders and illion TenderLink both sell a subscription that emails a supplier when a matching tender appears. EstimateOne describes itself as helping “builders, subbies and suppliers connect” and lists “commercial tender opportunities for subcontractors across Australia” — a construction marketplace, not a general alert service.

VendorPanel is different again. Its own material describes it as “a leading source-to-contract procurement platform”, and the page announcing its merger with Unimarket lists its market as “education, healthcare, government, and energy” — procurement departments, not suppliers. Councils run their tenders through VendorPanel; suppliers respond to what appears there. It is a publishing platform, and we ingest its feed as one of our sources.

So a supplier comparing these is really choosing between two things: an alert subscription, or a search tool. That distinction matters more than any feature table, and it is the one most comparison pages leave out.

What each one publishes about itself

Everything in this table came from each company’s own public pages on 13 September 2026. We have not tested any of it, and we have not estimated anything they do not state. Where a cell says “not published”, that means we looked and it was not there — not that the answer is unfavourable.

Two patterns stand out. Only one competitor publishes a price list, which makes the market unusually hard to shop. And the coverage numbers that are published are not comparable with each other: TenderLink counts sources monitored and opportunities per year, Australian Tenders counts tenders active right now, and nobody defines their terms.

Our own row comes from a different kind of source. The 2,034 figure is what the live API returned for run 948479844c50 on 12 September 2026, and anyone can re-run the query. That is a weaker marketing number and a stronger factual one.

Where we are behind

A comparison page written by a vendor that finds the vendor winning everything is worth nothing, so here is the part that goes the other way. Australian Tenders states 4,444 active tenders on its home page. Our live corpus held 2,034 on 12 September 2026. That is less than half.

illion TenderLink states 3,300 sources monitored daily and 41,000 opportunities a year, alongside 600 exclusive buyer partners who it says publish one in six public tenders. We run 23 nightly sources plus a set of one-time verified snapshots. On that measure the gap is far wider still, and their exclusive-partner claim describes something we do not have at all.

Neither figure is independently audited, and the terms are not defined — “opportunities” and “active tenders” are not the same unit, and “sources monitored” counts websites rather than results. But we are not going to argue our way out of a number we cannot beat. If the most tenders in one inbox is what you want, the published claims point elsewhere.

We also do not sell award data. TenderLink states 138,000 award records; our corpus holds published opportunities only, with no awards, no suppliers and no contract values. If you need to research who won what, we cannot help yet.

Where we are different, and it is not volume

The first difference is the gate. Browsing and filtering the whole Stipple corpus is free and needs no sign-in. Australian Tenders requires a subscription from $67 a month, TenderLink a subscription it does not price publicly, and EstimateOne a free account that limits how many tenders you can see per month. If you want to look before you commit, that is a real distinction.

The second is provenance. Every result names the source it came from, and one-time verified imports are labelled as snapshots rather than presented as live. You can see which portal a tender came from before you act on it.

The third is the one nobody else offers. Our source registry is a public endpoint that lists every source we attempt, its current status, and the reason it returned nothing. It says, in plain text, that South Australia is behind a “login wall: the listing needs a free supplier account”, that Charles Sturt Council “blocks automated access on every path tried”, and that Boroondara is redundant because “its tenders-and-contracts page names VendorPanel, so they already arrive in that feed”. Those are our failures, published.

A coverage claim you cannot check is a marketing number. Publishing the gaps is how we make ours checkable, and it is the reason the 2,034 above is a smaller figure than our competitors quote — it counts only what we actually hold.

• Free to browse and filter the entire corpus, no account, no key.
• Every result names its source; snapshots are labelled as snapshots.
• A public source registry listing every source, its status and why it failed.
• Capability matching: paste your website and the corpus ranks against what you do.
• No award data, no supplier profiles, and fewer live tenders than two of the four.

Which one you should actually use

For a construction subcontractor or supplier, EstimateOne is purpose-built and the others are not. Its own description — connecting “builders, subbies and suppliers”, with “commercial tender opportunities for subcontractors across Australia” — is a narrower promise than a general tender service makes, and narrower is better when it matches you.

For a supplier who wants the widest possible net and is comfortable paying for it, the published numbers point at illion TenderLink. Nobody else claims 3,300 sources, and if their exclusive buyer-partner arrangement works as described it covers material that open aggregation cannot reach.

For a supplier who wants a fixed, knowable price, Australian Tenders is the only one that publishes a price list: $67 a month for one user in one region, $99 for ten users Australia-wide, $145 for twenty users across Australia and New Zealand.

For a supplier who has not yet decided whether tendering is worth it — which, on our research, describes most small businesses looking at this market for the first time — start where looking is free. Browse the corpus, read what buyers in your state actually publish, and only then decide whether an alert subscription earns its monthly fee.

How we checked, and what to distrust

Every competitor claim on this page was taken from that company’s own public web pages on 13 September 2026, and is quoted or closely paraphrased. We did not sign up for any of these services, test their coverage, or estimate anything they do not publish. Where a cell says “not published”, we looked for it and did not find it. Prices and claims move; if you are reading this well after September 2026, check them again.

Our own figures come from the live tender source registry rather than from marketing copy: 2,034 tenders across 23 nightly sources, run 948479844c50, 12 September 2026. That endpoint is public and returns the same numbers to you as to us, including the list of sources that returned nothing and the reason each one did.

Two things you should distrust on principle. First, this page is written by one of the products it compares, and no amount of sourcing removes that. Second, none of the coverage numbers here — ours included — measure the same thing, because none of these companies define “tender”, “opportunity” or “source” the same way. The only figure on this page you can independently reproduce is ours, and that is the argument, not the size of it.
