The short version

  • Only Brex has a free tier, so it costs nothing to try first.
  • Each has a real cost: Brex the free Essentials tier is limited to two legal entities; Rutter a unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
  • They diverge on capability: Brex covers Corporate cards, Rutter covers Accounting and ERP.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Brex

  • The free Essentials tier is limited to two legal entities
  • Premium is $12 per user per month, so cost scales with headcount using the card
  • Enterprise and Smart Card pricing is not published
  • Eligibility criteria are not stated anywhere on the pricing page, which matters for a product that extends credit

Rutter

  • A unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
  • Write operations into accounting systems are where these products break, because each system validates differently, and a rejected journal entry surfaces as a support ticket against you rather than against the ERP.
  • No pricing is published beyond a sandbox trial, so cost cannot be compared against alternatives without a sales process, and pricing tends to scale with connected accounts.
  • QuickBooks Desktop and other on-premises systems require a local connector or hosted agent, which introduces installation steps your customers must complete and support burden you inherit.
  • Sync freshness varies by platform and by customer authorisation state, so a product promising near real-time figures will find some connections update far less often than the marketing implies.
