Payhawk is renowned for offering cutting-edge card, expense, and spend management solutions, all seamlessly integrated with NetSuite. We first became customers of Payhawk and quickly realised the potential it had for our own clients. The quality of the native integration with NetSuite is perhaps the greatest strength, which means no complex reconfigurations at setup, easy customisation of fields and categories, and real-time two-way syncing of data.
