# Banking as a Service — buyer checklist (RFP) Derived from ProductArena's evidence-graded user-story taxonomy for Banking as a Service: 53 judged requirements. Priorities mirror story weights (3 = must-have, 2 = should-have, 1 = nice-to-have). ## Account provisioning - [ ] **[must-have]** Open a real, insured deposit account through the API — application to active account fully programmatic, with sandbox parity so the flow is tested before launch - [ ] **[must-have]** The account structure is transparent — whether funds sit in FBO pools or individual accounts, where FDIC insurance actually attaches, and who can see the ledger, all documented plainly - [ ] **[should-have]** Issue unique account and routing numbers at scale — virtual accounts for reconciliation, per-customer collection accounts, and sub-accounts under a master structure - [ ] **[should-have]** Idle balances can earn — interest-bearing accounts or documented sweep options, with the rate mechanics and who keeps the spread spelled out ## Agenticness - [ ] **[must-have]** Plug MCP servers into this product so it can use their tools - [ ] **[must-have]** Connect an agent via an official MCP server - [ ] **[must-have]** Drive the product through a documented public API - [ ] **[must-have]** Delegate tasks to a built-in AI assistant inside the product - [ ] **[should-have]** Point an agent at llms.txt or agent-oriented docs - [ ] **[should-have]** Run the product headlessly / in CI for automation - [ ] **[should-have]** Use an official CLI - [ ] **[should-have]** Issue scoped/least-privilege API credentials for an agent - [ ] **[should-have]** Build against official SDKs - [ ] **[should-have]** Subscribe to events via webhooks - [ ] **[should-have]** Get AI-generated insights and suggestions from my data inside the product - [ ] **[should-have]** Set up automations that run autonomously in the background - [ ] **[should-have]** Operate the product with natural-language commands - [ ] **[should-have]** Explore an interactive API reference with runnable examples - [ ] **[should-have]** Download a machine-readable API spec (OpenAPI or equivalent) - [ ] **[should-have]** Rely on versioned APIs with a documented deprecation policy - [ ] **[nice-to-have]** Test against a sandbox environment without touching production data ## Automation depth - [ ] **[must-have]** Define rules that trigger actions automatically on events - [ ] **[should-have]** Perform bulk operations across many items at once - [ ] **[should-have]** Schedule recurring jobs or workflows - [ ] **[nice-to-have]** Version, review, and roll back my automations ## Banking agent access - [ ] **[must-have]** An agent can operate an account within policy — scoped credentials that let it read balances and initiate transfers under amount caps and counterparty allowlists, a use the vendor documents by name - [ ] **[should-have]** An agent can read the full banking picture — accounts, transactions, pending activity, documents — through a clean API or MCP surface without screen-scraping a dashboard - [ ] **[should-have]** The product ships its own AI for banking operations — natural-language search over transactions, drafted responses to disputes and alerts, anomaly summaries — built in, not bolted on ## Banking cards - [ ] **[should-have]** Accounts come with cards — issue virtual and physical debit cards tied to the account through the same API, with spend controls and digital wallet support - [ ] **[should-have]** Card and ACH disputes are handled properly — Reg E investigation timelines, provisional credit mechanics, and my operational responsibilities documented and tooled ## Banking ledger - [ ] **[must-have]** The ledger is real-time and event-driven — balance reads that reflect holds and pending activity, and webhooks for every transaction state change so my system mirrors the bank exactly - [ ] **[should-have]** Transaction data is rich enough to build on — counterparty details, rail-specific metadata, stable identifiers, and enrichment that makes a raw bank feed usable in-product - [ ] **[should-have]** The paper obligations are automated — monthly statements generated per account, and tax documents (1099-INT) produced and retrievable through the API ## Banking onboarding - [ ] **[must-have]** Customer verification is programmatic — KYC for individuals and KYB for businesses with document collection, watchlist screening, and clearly modeled application states - [ ] **[should-have]** Work the onboarding queue — see why an application is pending, supply additional documents, and understand which decisions are mine versus the bank's ## Banking risk controls - [ ] **[should-have]** Set risk controls per account and per program — transaction and velocity limits, holds on suspicious activity, and account freezes with documented reinstatement paths - [ ] **[should-have]** Fraud economics are explicit — who eats ACH return fraud, card disputes, and account takeover losses, with the platform's prevention tooling documented alongside the liability split - [ ] **[should-have]** Growth doesn't hit invisible walls — program-level limits, approval stages, and the path to raising them are documented rather than discovered in an email from the bank ## Money movement - [ ] **[must-have]** Originate ACH through the API — credits and debits, same-day windows, and the unhappy paths (returns, NOCs, reversals) modeled as first-class objects with webhooks - [ ] **[should-have]** Checks still work — programmatic check issuance and check deposit with image capture, because real businesses still receive and send paper - [ ] **[should-have]** The faster rails are there when I need them — domestic wires, RTP, and FedNow origination and receipt through the same API, with per-rail capabilities documented - [ ] **[should-have]** Money can cross borders — international wires or SWIFT, FX with transparent rates, and the coverage map of currencies and corridors documented ## Openness - [ ] **[must-have]** Export all of my data in open formats and leave - [ ] **[must-have]** Self-host the core product - [ ] **[should-have]** Do everything through the API that I can do in the UI - [ ] **[should-have]** Read the product's source under an open license ## Privacy posture - [ ] **[must-have]** Prevent my data from being used to train AI models - [ ] **[should-have]** Choose where my data is stored (region/residency) - [ ] **[should-have]** Control data retention and deletion - [ ] **[should-have]** Opt out of telemetry and usage tracking ## Sponsor model - [ ] **[must-have]** Exactly who holds the charter — whether the platform is a bank, a direct program with a named partner bank, or middleware between me and someone else's sponsor — and what happens to my customers if the platform fails - [ ] **[must-have]** The platform ledger reconciles to the bank core — documented daily reconciliation between what the API reports and what the bank holds, the failure that sank Synapse-era programs - [ ] **[should-have]** The compliance workload is tooled — transaction monitoring, sanctions screening, case management for alerts, and SAR-filing support with a clear split of duties between me, the platform, and the bank --- Source: https://ultrametric.ai/productarena/arena/banking-as-a-service (evidence-graded verdicts for 6 products) · methodology: https://ultrametric.ai/productarena/methodology
