Moss

Pricing is not published anywhere, so the only way to compare Moss with Pleo or Payhawk is to run parallel sales processes and reveal your spend volume to all of them.
Card limits are underwritten, so early stage companies and businesses with thin filed accounts are routinely offered limits well below what they need and the limit can be reduced on review.
Coverage is European and weighted to DACH, so any group with United States or Asian entities has to run a second card programme and reconcile two systems.
Invoice management is capable but not a full procurement or purchase order system, so businesses needing three way matching against goods receipts will find it thin.
As a non bank the credit product depends on partner banks and funding lines, which means the terms behind your limit are set by a party you do not contract with and can change without you being the cause.
