Api quality

Codify our expense policy — limits by category, role, and context — so in-policy expenses auto-approve and only exceptions reach a human C

Policy engine

Issue physical and virtual corporate cards to the team in minutes, each with its own spend limit C

Card issuance

Define rules that trigger actions automatically on events G

Pull transactions, expenses, and receipts through a documented REST API with OAuth and scoped tokens C

Api access

Restrict cards by category, merchant, and amount — and the platform auto-locks or declines out-of-policy spend at the point of sale C

Card controls

See company spend in real time — by team, category, and merchant — the day it happens, not when statements land C

Dashboards

An agent can pull uncoded transactions via API or MCP, propose categorizations and policy flags, and push clean coding back for review C

Agent access

Self-host the core product G

AI codes and audits expenses for me — reading receipts, suggesting categories and memos, and catching duplicates or fraud C

Ai coding

Allocate budgets to teams and projects and have card limits and approvals actually enforce them C

Budgets

Book flights and hotels in-platform with travel policy applied at booking time, not expensed and argued about later C

Booking

Perform bulk operations across many items at once G

Run accounts payable in the same platform — capture invoices, route approvals, and pay vendors by ACH, check, or wire C

Bill pay

Spend is coded as it happens — merchant, category, memo, receipt — so month-end close is a review, not an archaeology dig C

Close

An AI assistant enforces policy conversationally — chasing missing receipts, explaining declines, and answering "can I expense this?" before the spend happens C

Ai policy

Create single-vendor virtual cards for SaaS subscriptions and procurement so one compromised vendor never exposes shared credit C

Virtual cards

Every expense carries a full audit trail — edits, approvals, policy checks — that survives an external audit C

Audit trail

Receipts match to card transactions automatically — with e-receipts pulled from integrations — and I get nudged only when one is genuinely missing C

Receipt matching

Build multi-step approval chains — manager, budget owner, finance — with delegation and escalation when approvers sit on requests C

Approvals

Do everything through the API that I can do in the UI G

Issue and manage cards programmatically — create a card with a limit, lock it, update controls — via the public API C

Run multiple legal entities and currencies in one account with consolidated reporting and per-entity books C
