FAQ

Common questions.

Who is APB Intelligence built for? +
APB Intelligence is built for serious property investors, developers, SMSF trustees, property syndicates, development companies, family offices and investment advisors. Our buyers agency also operates inside the platform, meaning buyers agency clients receive a premium client portal. It is not designed for everyday home buyers or first-time investors.
What makes the development feasibility engine best-in-class? +
Our feasibility engine handles construction costs, finance, GST treatment, developer margin, holding costs, selling costs and tax — with full sensitivity analysis and scenario comparison. You can save multiple versions, compare different capital structures, and export professional PDF reports. It's built around how Australian developers actually structure deals, not US assumptions.
Is my data stored in Australia? +
Yes. APB Intelligence is hosted on Australian infrastructure. Your data never leaves Australia and is handled in accordance with the Privacy Act 1988 and Australian Privacy Principles. We take data security seriously — your portfolio data is among the most sensitive financial information you hold.
Can I manage multiple entities and structures? +
Yes. Professional and above plans support multi-entity structures including SMSF, family trusts, company structures and syndicates. You can track properties across entities and get a consolidated portfolio view at the top level.
How does the client portal work for buyers agency clients? +
Buyers agency clients receive a secure invitation to their own private portal. They can log in to see the properties you've sourced for them, due diligence reports, cashflow projections, documents and settlement progress — only their own data. It's a premium white-glove digital experience that complements your advisory service.
Is there a free trial? +
All plans include a full 14-day free trial with no credit card required. You get access to all features on your chosen plan from day one. Cancel anytime — we don't hold your data hostage.
