Deb Halliday
Deb Halliday is a qualified trainer, author, and co-founder of APX Training & Development, where she specialises in helping accounting firms build advisory teams that deliver beyond the business owner.
After over 17 years in practice, Deb founded and scaled The Accounts Ladies, an award-winning accountancy, bookkeeping, and financial coaching firm, before successfully stepping away from day-to-day operations in 2025. Her focus now is on helping accountants, bookkeepers, and financial professionals transition from technician-led businesses into scalable, advisory-led firms.
Deb is the co-author of Advisory Teams, written with Tim Seymour, which introduces a new model for delivering advisory through a team, not a single individual. Together, they show how firms can remove the owner as the bottleneck and create consistent, high-value client relationships across the team.
Through APX Training & Development company, Deb provides practical training, structured programmes, and ready-to-use resources that help firms embed advisory into everyday delivery, building capability across their teams, not just at partner level.
With a background in both accountancy and professional training, including earlier experience in a Central London training company, Deb is known for her straightforward, no-nonsense approach. She focuses on making advisory practical, scalable, and achievable for firms at every stage.
