Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Extend

  • It depends on an existing business credit card relationship, so a company without a qualifying Amex, Visa or Mastercard business card cannot use it as a standalone card issuer.
  • The free Starter plan is capped at five users and 100 cards a month, which small but growing teams will outgrow quickly and need to upgrade past.
  • The Pro plan enforces a ten-user minimum, so a company with only two or three people who need virtual cards pays for unused seats.
  • Rewards, credit terms and dispute resolution still run through the underlying card issuer, so Extend cannot improve or change those terms; it only adds a control layer on top.
  • Deeper ERP integrations such as NetSuite and Dynamics 365 are reserved for the custom-quoted Enterprise tier, so companies needing them lose the pricing transparency of the published Starter and Pro plans.

Paychex Flex

  • No published pricing rates available
  • Pricing varies significantly based on employee count and business needs
  • All pricing requires direct contact with sales team
