Quickli and Thinktank team up to drag broker serviceability into the modern era

Australia's mortgage broking industry has quietly been putting up with a pain point for years: lender serviceability calculators that are clunky, inconsistent, and in some cases, still living inside an Excel spreadsheet. Thinktank and Quickli have just done something about it.

The two companies announced today the launch of brand-new serviceability calculators for Thinktank's product suite including Residential, Commercial, SMSF, and Private Streamlined into the Quickli format that more than half of all mortgage brokers in the country use every day.

The calculators are now accessible across aggregator portals, alongside Thinktank’s website and direct broker portal, enhancing the user experience for brokers.

Why this actually matters

Quickli is used by more than 14,000 mortgage brokers — a number that represents more than half of every mortgage broker operating in Australia today. It's a userface brokers know and love and when a lender adopts it, the friction disappears.

And friction, it turns out, was exactly the problem. Thinktank's own findings identified that its legacy Excel-based calculator system was creating barriers for brokers.

"Our business has always been built around brokers, so anything that makes it easier for them is a priority for us," said Belinda Wright, General Manager of Sales at Thinktank. "Quickli is already part of how many brokers work so it made sense for us to meet them where they are rather than ask them to adapt to an entirely new solution."

Wright was candid about where the push came from: broker feedback. "They wanted speed for early conversations, but also confidence that the numbers stack up against policy when it matters. Having both a quick view and a full calculator gives brokers the flexibility across our product suite."

Quickli's growing lender play

For Quickli, the Thinktank integration is more than a one-off partnership — it's the expansion of what the company is calling its Serviceability-as-a-Service offering for lenders. The model is straightforward: rather than every lender building and maintaining their own calculator infrastructure, Quickli provides the platform, the consistency, and — crucially — the user experience that brokers already know and trust.

It's a sensible proposition for lenders. Internal development costs drop. Broker experience standardises. And the lender's products land inside a workflow that over half the industry already uses every day.

"We've worked with Thinktank to transform the broker experience in a big way," said Darren Davis, Head of Sales at Quickli. "Brokers can now assess Thinktank deals with the same crisp, instantaneous response they expect from Quickli, and we've also digitised products that go well beyond standard residential lending."

That last point matters. SMSF and private lending products aren't simple to calculator-ise. Getting them into the Quickli format — accurately, and in a way that holds up against policy — is a genuine technical achievement.

The numbers behind the platform

It's worth pausing on just how embedded Quickli has become since its 2021 launch. The platform has consolidated more than 50 lender serviceability calculators into a single interface, with users having now run over two million scenarios through the system. That organic growth — the company notes it has been entirely word-of-mouth driven — speaks to a platform that has clearly landed well with its audience.

The accolades back that up. Quickli took out Industry Supplier of the Year at the 2025 Finance Brokers' Association of Australia Awards of Supremacy, Service Provider Innovator of the Year at the 2025 Broker Innovation Awards, and Broker Technology Platform of the Year at both the 2023 and 2024 Mortgage Business Awards.

Beyond the core calculator, Quickli also offers AI-powered credit analysis tools, document renaming automation, lender-specific postcode lookup, SMSF and Alt Doc specialist tools, and a broker community for peer support — all wrapped in a support model the company says delivers 90-second average response times from real humans.

Thinktank's broker-first DNA

For Thinktank, the move is consistent with how the business has operated since it was founded in 2006. The lender works exclusively through mortgage brokers — no proprietary channel, no direct-to-consumer play — and has built a $18 billion-plus loan book off the back of that model. SMSF lending came in 2013, residential in 2018, and private lending solutions as recently as 2024.

It now has more than 200 staff across Sydney, Melbourne, Brisbane, Perth and Adelaide. Plugging the full product suite into the platform that more than half its broker partners use daily looks, in hindsight, like an obvious move. Sometimes the obvious moves are the ones that take longest to arrive.

"To put it simply, we're here to service the industry and make brokers' lives easier," added Davis. "Working with Thinktank as one of the country's most respected lenders is an exciting opportunity to empower brokers to better serve their customers."
