If you've ever stared at a complex payslip wondering which income lines actually count — and then spent the next hour working through three different lender calculators — you already know why AutoCalc exists.

Peter Liu has been a mortgage broker since 2011. Over 15 years and more than a thousand client applications, he lived this problem daily. Australian payslips vary enormously from employer to employer: a hospital nurse, a mining contractor, and a Sydney banker each get paid very differently — and every lender reads those payslips differently too. Overtime shading, bonus treatment, YTD requirements, annualisation rules — the complexity is real, and it adds up to hours of work per client.

Even after 15 years in the industry, a complex payslip could still take 30 minutes just to parse. Then came the lender calculators. A full borrowing capacity assessment? Easily an hour.

Since 2018, Peter had been mentoring a new generation of mortgage brokers alongside his brokering work. Year after year, the same questions came up: How do I read this payslip? Which income does this lender accept? What's the shading rule here? It became clear this wasn't just Peter's problem — it was the whole industry's problem.

By 2025, AI was becoming genuinely powerful. Peter started using it to draft emails and summarise documents. Then a bigger idea clicked: what if AI could read any payslip, classify every income line automatically, and apply each lender's exact policy rules — all in one go?

He rang Sam Chen.

Peter and Sam have been close friends for over a decade. Sam is a senior engineering leader with deep experience in financial services system design and holds formal credentials in AI and machine learning. He knew immediately this was a problem worth solving.

“When Peter walked me through it, the answer was obvious. Brokers are doing highly skilled work, and a huge chunk of their time is consumed by things a good system should handle automatically.”

Together they built AutoCalc — Australia's first platform to go from payslip to borrowing capacity comparison automatically. Upload a payslip, and AutoCalc classifies every income line correctly, annualises it correctly, and runs it through 22+ lenders' policies in minutes. No more manual parsing. No more guessing at shading rules. No more hour-long spreadsheet sessions.

Because accurate income in means accurate borrowing capacity out. And that changes everything for your clients.

We built the tool we always wished we had. Now it's yours.
