Brex
· #95 most-usedAutomate corporate card management, expense reconciliation, and vendor payments
Brex is the AI-powered spend platform for modern businesses — combining corporate cards, expense management, reimbursements, vendor payments, and budget controls in one place. Connect Brex to Actionist and your agents can list and reconcile settled transactions daily, monitor budget utilisation and alert on burn rate, provision and manage virtual cards throughout the employee lifecycle, create vendor records and initiate ACH and wire payments, and run weekly compliance sweeps with a full audit trail — all without anyone logging into the Brex dashboard.
Eliminates manual work. Agents eliminate manual transaction reconciliation, receipt chasing, card provisioning, vendor onboarding, budget monitoring, and vendor payment runs that currently fall on finance and operations staff.
What your Brex agent runs on autopilot
A week of scheduled jobs your Actionist agent will execute on your behalf.
Brex × every other app you use
End-to-end automations that span multiple apps — each one a real business outcome.
Invoice approved to vendor paid, no manual steps
When an invoice row is marked approved in Google Sheets, the agent checks whether the vendor already exists in Brex, creates the vendor record if not, confirms the cash account balance is sufficient, initiates the ACH transfer, and posts a confirmation to the #finance Slack channel — a complete payment run in one automated sequence.
Time saved for your team — every week, on autopilot

What your team gets back — two angles: what you stop doing manually, and what that's worth.
What you do manually today
What your agent runs for you
- Sales20 min / weekManual expense-to-deal attribution
Sales reps manually log expense receipts and match them to deals in the CRM, or the task falls to an ops admin who does it retrospectively from monthly transaction exports.
Sales Agent0 minAgent provisions deal cards and reconciles spend automaticallyWhen a deal moves to the demo stage, the agent creates a locked virtual card for deal expenses and maps all spend back to the CRM deal record weekly — acquisition cost is visible per deal without manual tracking.
- Marketing15 min / weekManual campaign budget checking
Marketing managers log into Brex periodically to check budget utilisation for each campaign — easily forgotten mid-campaign, often discovered only when a card declines.
Marketing Agent0 minAgent monitors campaign budgets and alerts on burn rateThe agent lists all campaign Brex budgets weekly, calculates utilisation and projected exhaustion date, and posts a traffic-light alert to the marketing Slack channel — overspend is caught before it happens.
- Customer Support25 min / weekManual receipt collection at month-end
Finance staff manually pull the unreceipted expense report, identify cardholders, and send individual emails or Slack messages to chase receipts — time-consuming and often incomplete before the close deadline.
Customer Support Agent0 minAgent chases receipts automatically before month-endEvery Wednesday the agent identifies support team expenses without receipts and sends each cardholder a personalised Slack message listing their specific missing receipts — compliance improves without a finance person doing manual chasing.
- Human Resources30 min / weekManual card lifecycle management
HR submits a ticket to finance to provision Brex access for new hires — often delayed by 1–3 days. Offboarding card suspension is manual and frequently missed, leaving ex-employees with active corporate cards.
Human Resources Agent0 minAgent handles card provisioning and suspension automaticallyWhen a new hire record is created, the agent invites them to Brex and creates their card before day one. When offboarding is recorded, the agent suspends the card and removes access the same day — zero manual Brex steps for HR.
- Finance120 min / weekManual transaction reconciliation and payment processing
Finance staff export Brex transactions monthly, manually categorise them, chase receipts over email, and log into Brex to initiate each vendor payment individually — the most time-intensive part of the finance calendar.
Finance Agent0 minAgent runs daily reconciliation and weekly payment runsThe Finance Agent pulls settled transactions daily, appends them to the GL with categories, chases missing receipts, and initiates approved vendor payments — reducing month-end close from days to a review of already-reconciled data.
- Operations35 min / weekManual vendor onboarding and card requests
Operations submits vendor details to finance for manual entry in Brex, requests a virtual card via email or Slack, and updates the internal vendor registry separately — three separate manual steps that often span multiple days.
Operations Agent0 minAgent maintains vendor registry and provisions project cardsWhen a new vendor contract is signed, the agent creates the Brex vendor record, provisions a locked card, and logs both to the vendor registry — every new supplier is payment-ready the day the contract is executed.
- Legal50 min / weekManual expense compliance review
Legal manually requests transaction exports from finance, reviews them in a spreadsheet for policy violations, and updates a separate audit log — a 2-hour monthly task that is difficult to do more frequently.
Legal Agent0 minAgent runs weekly compliance sweeps with full audit logThe Legal Agent reviews all card transactions for policy violations weekly, flags exceptions to legal counsel, and maintains an immutable audit log in Notion — audit readiness is a by-product of weekly operations, not a month-end scramble.
