We appreciate the invaluable support provided by AAB during our complex transition. With limited resources, AAB quickly mobilised experienced personnel familiar with offshore payroll, expense systems, and time writing processes. Their expertise ensured a smooth handover, and the process felt routine during the first post-completion month. AAB’s support was instrumental in ensuring a seamless transition.
Andy Bell, VP Finance, Serica Energy
