Choosing an aggregator is one of the most important decisions you’ll make as a broker. Get it right and you’ll gain a genuine partner that can shape how you work, support your clients and help you grow with confidence. Get it wrong and you’ll feel the impact every day.
For experienced brokers, choosing an aggregator is rarely about features alone. It’s about selecting a partner that aligns with the kind of business you’re building. Whether you’re diversifying into commercial or asset finance, acquiring another broker’s book, building a team, or planning your eventual exit, the aggregator you choose shapes what is possible and what is practical.
This guide outlines the key areas to compare when choosing a new aggregator or considering a switch.
What does a mortgage aggregator do?
At a minimum, a mortgage aggregator gives brokers access to a panel of lenders and provides some of the infrastructure needed to run a brokerage: commission processing, technology, compliance support and a licensing framework. Beyond that baseline, the aggregator you choose shapes how efficiently your team operates, what support you can call on and how quickly you can grow.
More than lender access
Lender relationships are fundamental, but they’re the starting point rather than the whole offer. A strong aggregator also brings specialist support you can reach, technology that removes manual administration, compliance expertise, training, marketing resources, and data that shows you where the opportunities sit in your existing book.
How your aggregator needs change as you grow
As your business matures, your priorities evolve. Early on, the focus is on writing loans and building a client base. Later, you need support to grow your business, whether that’s diversifying into commercial lending, acquiring a loan book, managing a growing team, or structuring the business so it holds value at exit. An aggregator that supported your first 100 settlements may not have the infrastructure, the product breadth, or the strategic support for what comes next.
Which brokers should consider joining or switching aggregators?
Established brokers considering a switch
If you’ve been broking for years, switching aggregators is no longer just a simple comparison between lender panel, commissions, technology, and support. Those factors still matter, but they sit beneath a bigger question: what kind of business are you building and can your aggregator get you there?
The more you grow, the fewer brokers there are solving the problems you are solving. That is when specialised expertise, strategic support and access to peers at the same stage stop being nice to have and start shaping what the business can do next.
A switch isn’t about leaving a bad experience behind. It is about recognising that the next stage of your business needs a different kind of partnership: one with the breadth of product, the depth of support and the operational infrastructure to help you execute on your plan, not just write more loans.
New brokers and banker-to-broker career switchers
If you’re new to broking, the foundations matter most: practical onboarding, mentoring, lender accreditation support and clear compliance guidance. Coming from a bank, allow time for the move from one product set to a full panel and look for an aggregator that will invest in getting you there.
Leads are usually the highest priority early on, but ownership is the one that compounds. Ask who owns the client relationship and the trail attached to it. Trail is the asset you start building from your first settlement, and if you do not own it, more volume just means more loans written rather than a business you can eventually sell or hand on.
8 factors to compare when choosing a mortgage aggregator
1. Lender panel and product access
A strong lender panel is about more than just numbers. The real value lies in the breadth of products, lending specialisations and opportunities available through an aggregator’s panel, which can shape what you can do for your clients today and where you can take your business in the future. A panel of 80+ lenders across major banks, second-tier lenders, non-banks and specialist providers can mean more options for complex scenarios, sharper pricing competition on straightforward deals and greater confidence that you’re meeting Best Interests Duty from a position of genuine choice.
When comparing lender access, look at:
- Whether the aggregator provides the accreditations, expertise and support needed to build capability in commercial, asset finance, SMSF lending and construction finance.
- How quickly new lenders are added when the market shifts.
- Accreditation requirements and turnaround times for individual lenders.
- The practical quality of lender relationships, including access to lenders through events, webinars and other opportunities, alongside support for more complex applications.
Don’t overlook white labels. The strongest aggregators offer their own branded home loan products alongside the broader lender panel. A well-designed white label range can give clients more competitive rates and flexible product options. It may also support faster turnaround where the aggregator manages the process end to end.
The depth and performance of a white label range is one of the clearest points of difference between aggregators and one of the least compared. Ask what it offers your clients, how it performs in practice and where it sits alongside the rest of the panel.
2. Technology and workflow tools
Broker technology platforms are increasingly comparable, so the real difference comes down to how well the technology supports your business as it grows. Look for the scalability and visibility to manage growing teams, more complex processes and an expanding book, without adding unnecessary complexity to your day-to-day operations.
Look past the demonstration and ask:
- How configurable are the workflows? This is one of the most underweighted considerations. The ability to tailor workflows across teams, loan types and processes is a genuine lever for growth. It helps you add loan writers without chaos, run residential and commercial lending side by side, and maintain consistent quality as you scale.
- How will my data be migrated? The more established your business, the more important a smooth transition becomes. Ask how client records, loan information and historical data will be transferred and supported.
- How much lending automation is built in? Data pre-fill, document collection, serviceability tools, automated compliance checks and status tracking can remove hours from every application.
- How connected is the ecosystem? Data entered once should flow from fact find to lodgement, compliance record and commission statement without unnecessary rekeying.
AFG’s BrokerEngine Plus is part of its technology offering and can also be accessed by brokers outside the AFG network. It gives brokers a practical way to assess the platform independently, including how it supports their workflows, before making a broader aggregation decision.

3. Commission structure and value for money
Aggregator remuneration models generally fall into two camps: a percentage split of your commissions, or a flat monthly fee while you retain 100% of commissions.
Brokers can spend a lot of energy comparing the two. It’s worth understanding the numbers, but the fee model alone is rarely what separates a good year from a great one.
The bigger number is not just annual income. It’s the value of the business you’re building. An aggregator that helps you diversify revenue streams, retain trail income, scale efficiently and build a business a buyer would want to acquire can have a far greater impact on long-term outcomes than the difference between fee structure. The right technology, referral opportunities, marketing support, active BDM support and clear routes into commercial lending can all contribute to stronger business value over time.
Then check the details that can catch brokers out later: payment frequency and reliability, additional-user or office fees, software charges, clawback arrangements and any costs tied to leaving.
4. Trail commission ownership and exit terms
Your trail book is one of the most valuable assets in your business. Treat ownership, portability and exit terms as a central commercial consideration, not fine print.
Trail arrangements shape more than your monthly income; they shape what your business is worth. If you are planning to sell or transition in the next three to five years, a buyer will price your book on how secure and transferable the trail is. Clear ownership, unrestricted transfer and predictable payment terms support a stronger multiple. Transfer approval requirements, extended notice periods or trail that reverts on exit will be discounted.
Ask how your trail is treated if you leave, sell your business, merge with another brokerage or retire. There may be established pathways within the same aggregator. Confirm whether there are notice periods, payment changes, transfer restrictions or ongoing obligations.
Ask the same questions from the buy side. If you acquire another broker’s book, establish whether trail transfers in full when both parties sit under the same aggregator, what approvals are needed, how long the transfer takes, and whether the existing trail rate travels with the book or resets to your own agreement.
5. Compliance and risk support
Compliance is a fundamental part of building a sustainable brokerage. The right support and processes can help you build your business on solid foundations, giving you confidence to grow without worrying that your systems will hold you back.
Compare aggregators on:
- Whether you can operate as a credit representative under their licence or hold your own ACL with their support.
- Compliance workflows built into the platform, so Best Interests Duty evidence, needs analysis and file notes are captured as you work rather than reconstructed later.
- Audit and file-review programs designed to help you stay prepared.
- Access to compliance specialists when an unusual scenario lands on your desk.
- The quality and frequency of professional development, policy updates and CPD support.
Good compliance support is often invisible when everything runs smoothly and invaluable when it doesn’t. The right partner gives you clear processes, practical access to expertise and the confidence to focus on your clients.
6. Broker support services
Technology and lender panels matter, but broker support is often what members mention most when they explain why they stay or why they leave. For brokers, the question is whether that support is proactive, commercially useful and still available once onboarding is over. Look for:
- Business development managers with a regular, structured contact cycle, so support isn’t something you need to chase.
- Support for growth, whether that means recruiting loan writers, improving operational efficiency or diversifying into commercial or asset finance.
- Succession and exit planning support, including guidance on business value, trail ownership and the factors that can influence a future sale or transaction.
- A genuine broker community. Peer networks, conferences and state-based events are often where practical business improvement happens.
- Ongoing learning and development to help you keep building your skills, refine your strategies and grow your business, with training, new-to-industry pathways and automated CPD tracking.
Ask existing members how support changed after they signed. Onboarding enthusiasm is universal; support in year three is the more meaningful test.
7. Marketing and client retention
A successful brokerage needs more than new leads. It needs a reliable way to stay connected to existing clients, generate referrals and uncover opportunities within its loan book. As your business grows, client retention becomes less about effort and more about systems.
When comparing aggregators, look beyond standalone marketing tools. Consider how they support your brand through website and social media support, branded campaigns, and marketing automation that keeps your clients engaged while you run your business. The right combination of technology and support can help you stay front of mind with less manual effort.
This isn’t just a marketing consideration. Strong client engagement drives retention, repeat business and referrals, while increasing the long-term value of your loan book. For established brokers, that’s growth that can compound well beyond the next settlement.
Your all-in-one marketing platform
AFG’s Smart program is designed for brokers who want to see their business soar. It’s the marketing engine that propels your business forward by helping you attract customers and grow your business.
8. Strategic growth and business planning support
Your aggregator relationship can shape what your business can become, not just how efficiently it runs.
If you are planning to acquire another broker’s book, your aggregator needs to support clean data migration, trail integration and client transition. If you are diversifying into commercial or asset finance, you need more than panel access: you need accreditation pathways, specialist BDM support and workflows that can handle a different product set alongside your existing residential book. If succession or exit is on the horizon, the way your aggregator handles trail ownership, business valuation support and transition planning directly affects what your business is worth and how smoothly you can hand it on.
Ask how your aggregator supports key business milestones and ask to speak with members who have been through them.
Questions to ask before joining or switching aggregators
Before choosing an aggregator, it helps to ask a few practical questions that go beyond lender numbers and headline fees:
- What does data migration involve and what support is provided to move my existing client and business data across?
- How well does the technology support my workflow, from fact find and lodgement through to compliance and commissions?
- What support is available if I want to acquire another broker’s book?
- How does the aggregator support business valuation, succession planning or exit?
- What support is available if I want to diversify into commercial or asset finance?
- How broad and relevant is the lender panel for the clients and lending scenarios I want to support?
- What is included in the fee structure, including software, additional users and ongoing support?
- What compliance guidance, training and audit support is available?
- How will I be supported by BDMs and specialist teams once I’m onboarded?
- Can I speak with brokers at a similar stage of business about their experience?
If you’re already established and considering a move, there are additional considerations around trail arrangements, client data, lender accreditations and transition planning.
How AFG supports brokers
AFG has supported Australian brokers since 1994. Today, more than 4,300 brokers nationally use AFG’s technology, lender panel and specialist support to build successful, sustainable businesses.
Technology that scales with your team
AFG’s technology ecosystem is designed to give brokers greater visibility across their business and support them as their teams and processes grow. BrokerEngine Plus brings core deal processing and customer management functions together in one platform, helping brokers work more efficiently and manage increasing complexity as their business scales.
Lender choice and pathways to diversify
AFG’s panel of 80+ lenders and 10,000+ finance products give brokers more ways to support the needs of their clients. Beyond residential lending, AFG supports diversification into commercial or asset finance through accreditation pathways, specialist training, lender access, and ongoing partnership support. The right relationships, product access and practical support can make diversification feel like a considered next step rather than an operational leap.
Support that outlasts onboarding
Structured BDM contact, compliance specialists, professional development and a national broker community mean the support you’re shown before you join is the support you still have in year three.
A business you own
Your brand, your clients, your trail. AFG provides the panel, the platform and the support behind your business, and you stay independent and in charge of the direction it takes. That means ownership of your trail book as a genuine business asset. It means the flexibility to diversify, acquire, restructure or plan your exit on your own terms, with an aggregator that has the breadth and the operational depth to support whatever you decide to build.
Finding the right fit for your brokerage
The best aggregator isn’t automatically the biggest, the cheapest or the one with the slickest technology demonstration. It’s the one that fits how you want to work and where you want to be in five years.
Compare the commercial terms, then compare the things that will actually decide your next three years: whose lender panel and white label range give your clients genuine choice, whose platform saves your team real time, whose compliance support reduces your risk, and whose people are still helping you build the business long after you sign. Ask detailed questions and speak to members running businesses like yours.
When the fit is right, an aggregator can do more than support your next loan. It can give you the capability, confidence and opportunity to build a business you’re proud to lead and a valuable asset that you own.

FAQs
Aggregators all provide the same baseline: lender access, commission administration, technology, compliance support and a licensing framework. The differences that matter are competitive products that offer choice, compliance that protects your business and asset, technology that enables growth and workflows custom to your business.
Focus on lender breadth, technology integration and workflow flexibility, full commercial terms, proactive support and diversification pathways. Speak to members who are at a similar stage of business and ask what support looks like beyond onboarding.
Not on its own. Look at the relevance and depth of the panel across the scenarios you handle, including specialist lending, and check accreditation requirements and turnaround times. A useful panel gives your clients choice, not just a larger number to quote.
A strong white label range can give your clients more competitive rates and flexible product options alongside the mainstream lender panel. It can also be a useful point of difference in turnaround and service. Ask about product depth, performance and where it fits your client base.
Understand whether the model is a commission split or a flat monthly fee, then look at the entire commercial picture: software, users, offices, clawbacks, payment reliability and exit costs. Most importantly, assess what the model can credibly help you achieve in business growth, including whether you retain ownership of your trail book and build long-term value in the business you’re creating.
Ask who owns and develops the platform, how connected it’s across the lending journey, how configurable workflows are, what automation is included and how AI is being applied. Then speak to members who have used it for at least six months.
The test is what happens when you describe your plans for the next three to five years. If diversifying, acquiring a book, building a team or planning an exit gets met with a workaround rather than a pathway, you’ve probably outgrown your current arrangement.
