About

Susan Holtmeulen – Principal BAS Agent & Founder

With over 15 years of hands‑on bookkeeping experience, Susan brings depth, steadiness and genuine care to every client relationship. She pairs formal qualifications: Graduate Certificate in Business, Cert IV in Bookkeeping & Accounting, BAS Agent Registration, Xero Advisor | Xero Payroll, XBert Advisor, Syft Annalytics Advisor, with a calm ability to translate complex data into clear, confident decisions.

Having worked across a wide range of industries, Susan adapts quickly to each client’s operational style and growth stage. A proud career highlight has been building QiBalance from a solo practice to a cohesive team of five, while supporting clients with revenues surpassing $6M. She credits the smooth expansion to intentional communication and the power of women’s peer circles that model collaborative leadership.

As Principal BAS Agent, Susan’s passion is making business data meaningful for small to medium enterprises by spotting patterns early, protecting cash flow, and removing the “numbers stress” that keeps owners up at night.

Perth‑based, Susan has two sons (and is excited about her first grandchild), plus a lively collection of chickens and an abundant veggie patch. Outside the ledger you’ll find her cooking, hiking local hills, or practicing Italian.

Pauline van Eeden – BAS Agent & Senior Bookkeeper

A natural investigator turned numbers‑sleuth, Pauline pairs a PhD and 30‑year career in medical research with more than six years of professional bookkeeping. Her research days earned her Young Investigator Awards from the Royal Perth Hospital Medical Research Foundation and the Foundation Fighting Blindness; today that same forensic mindset shines when she untangles complex client histories. She once rebuilt two full financial years after discovering payroll had been run from two Xero files under the same ABN, and regularly manages multi‑entity structures (up to a dozen accounting files for a single property‑investment group).

Pauling brings a range of qualifications including a PhD (Diabetic Retinopathy), Cert IV Accounting & Bookkeeping, and she is a Registered BAS Agent. Pauline’s ethos is simple: practical accuracy, plain‑English explanations, and the calm certainty that no project is too tangled to repair. She helps owners move from “adrift” to confidently on track: catching issues early, safeguarding compliance, and making big numbers feel manageable.

Based south of the river, Pauline shares life with her rescue dogs Tika and Evie and a fleet of bikes. A Harley Sport Glide rider, served as Treasurer for the not‑for‑profit Dykes on Bikes, co-hosted a biking radio podcast, collaborated on the production of a local bird guide book as a teenager, and these days can usually be spotted on weekend rides with mates or planning the next charity run.

Geraldine Mandin - Bookkeeper

Geraldine brings a calm, meticulous presence and a genuine desire to help, shaped by her earlier career in immunology research where precision, disciplined documentation and pattern‑spotting were daily practice. Now, with 2 years of bookkeeping experience and a scientist’s analytical lens, she supports growing businesses with clear reconciliations, tidy files and quietly proactive communication. She is currently completing her Certificate IV in Bookkeeping & Accounting (in progress – expected completion end 2025) and is certified in Xero Advisor | Xero Payroll and Syft Annalytics Advisor and has published scientific papers (under her maiden name), underscoring her commitment to evidence‑based thinking.

A standout early achievement: in her first role she reconciled months of backlogged transactions and recovered thousands of dollars stalled with a supplier, using patient, persistent follow‑up. Geraldine also invests deeply in professional growth, illustrated by completing a 900‑page two‑volume work on Emotional Intelligence, applying those insights to empathetic client conversations and change management.

Her ethos is simple: translate numbers into clarity, create orderly financial rhythms, and reduce the low‑grade stress that owners feel around “unfinished” accounts.

Perth‑based, Geraldine relaxes with her family at the beach (feet in the water, book in hand), and expresses creativity through sewing, furniture building, and nurturing her daughters’ small origami venture from concept to market feedback and custom orders.

Will Parker – Certified Bookkeeper & Cyber Warden

Will is a certified bookkeeper with 1 year of hands‑on bookkeeping experience (and prior exposure through study and volunteer administration) who brings sharp analytical curiosity and a calm, reassuring manner to every file. Equipped with a Cert IV in Accounting & Bookkeeping, Xero Advisor | Xero Payroll, and a Cyber Warden certification, Will couples technical accuracy with a people‑first mindset, helping small business owners move from frazzled to assured.

An early standout achievement: rapidly reconciling several months of domestic and international transactions for a not‑for‑profit. She was busy untangling multi‑currency and GST nuances under tight time pressure so the organisation could report with confidence. Will also contributes to the QiBalance blog, shaping clear, plain‑language articles on payroll, tax and GST, and isn’t afraid to form a thoughtful, well‑reasoned opinion (especially on payroll tax compliance).

Will’s background includes volunteer retail work (op‑shop), studies in politics and gender, and an award‑winning essay that honed persuasive, structured communication. These skills are now channelled into explaining numbers without jargon.

Based in Perth with family, a much‑loved dog, and a bookcase that’s “half library, half aspiration,” Will can usually be found reading (or planning to), and exploring music across genres.

Lisa Allegretta – Certified Bookkeeper & BAS Agent

Lisa brings 9 years of financial administration and bookkeeping experience: 7 years dedicated bookkeeping plus 2 years prior specialising in accounts payable and payroll. A former small business owner in the building & construction industry, she understands firsthand the juggling act of operations, cash flow, compliance and people. As a result, her support is always practical, empathetic and grounded in real‑world pressures.

Lisa’s blend of formal finance, systems and logistics qualifications: Cert IV Bookkeeping & Accounting, Registered BAS Agent, Xero Advisor | Xero Payroll | Xero Migrate, Cert IV Warehousing & Logistics, sharpens her process thinking and attention to detail.

Lisa thrives on complex data puzzles; what overwhelms others feels like a solvable mystery to her. A recent standout achievement for Lisa was conducting a deep investigation for a valued client. She processed 12 months of incorrect transactions across three entities and produced a clear report that restored accuracy and confidence.

Lisa values her ability to move owners from overwhelmed to in control, creating clean, comprehensible financial foundations and calm, repeatable admin routines.

Perth‑based, Lisa relaxes with her husband and two daughters by reading, watching sport or heading outdoors to camp under Western Australian skies.
