I've implemented Payhawk at two companies and overseen it at a third, using cards, expenses, bill pay, approvals and the Xero sync. The product itself is excellent. The interface is clean, the flow from spend to approval to accounting sync is logical, and it takes a lot of manual bookkeeping off the finance team. It's the easiest spend tool I've come across for employees to use, so adoption is quick. The product team clearly knows what it's doing and keeps shipping useful improvements. Early on, the overall experience with Payhawk was great.
I really like that Payhawk is easy, fast, and reliable. It made the initial setup incredibly easy for me. I received support on two card transactions within minutes, providing me with full details and instructions. This level of quick and detailed support is something I value highly.
