Workday AI
Pros
- + Agent fleet does real work against real ledgers — contract review, document-driven accounting and frontline absence handling are tangible workflows, not chatbots
- + Agent System of Record is the clearest governance answer on the market for managing first- and third-party AI agents with roles, budgets and revocation
- + Self-Service Agent answers policy questions with citations back to source documents and executes routine employee actions without tickets
- + Acquisition integration is fast and coherent: HiredScore (2024), Evisort (2024) and Paradox (closed October 2025) all feed the agent stack
- + Depth of system of record across HCM, payroll, planning and financials means agents can act across workflows a bolt-on assistant can't reach
Cons
- - No public pricing whatsoever, and Flex Credits put a usage meter on top of already-large enterprise subscriptions
- - Implementation is a quarters-long project with an integrator; third-party TCO estimates run $300K to $2M+ with implementation often dwarfing licences
- - UI density and customisation speed draw consistent complaints; casual users face a real learning curve
- - Agent value tracks data residency in Workday — contracts and documents outside the platform thin out coverage
- - Parts of the Agent System of Record (cost forecasting, improvement tracking) read as roadmap rather than shipped capability in the material I reviewed
Brex
Pros
- + Policy enforcement happens at the card — in my review of the workflow, out-of-policy transactions are declined before money moves instead of documented afterwards
- + Essentials is $0 per user and includes rules, reimbursements, bill pay, travel booking, reporting, and API access — most competitors charge per seat from day one
- + AI receipt generation for common vendors and automatic categorization remove the most repetitive tasks in monthly expense closing
- + Real-time reporting across cards, reimbursements, travel and payments answered spend questions in my test workspace without spreadsheet exports
- + Documented compliance posture: SOC 1 Type I, SOC 2 Type II, PCI-DSS Level 1, with FINRA/ITGC/NYDFS-aligned controls
Cons
- - Eligibility is selective by design — the June 2022 SMB exit (tens of thousands of customers dropped) means bootstrapped small businesses are a poor fit
- - US-centric underwriting, cards, and support; international companies without US presence face real friction
- - Credit limits and reward tiers depend on qualification, and the full cost of the platform is shaped by interchange and float, not just the seat fee
- - Multi-entity and advanced automation start at Premium ($12/user/month) and Enterprise quotes; software-usage billing exists beyond the per-user fee
- - No revolving credit — charge-card behavior is the model, which does not fit companies that need carried balances
