Brex Release Notes

You can now sign into Brex with a passkey instead of your password and multi-factor authentication (MFA).

Passwords and one-time codes can be phished, guessed, or stolen, and that's often how account takeovers start. Passkeys close that gap.

Passkeys let you sign in with something your device already uses to verify you: biometrics (such as Touch ID or Windows Hello) or a device PIN. There's nothing to reuse or hand to an attacker, which is what makes passkeys phishing-resistant.

Signing in with a passkey is faster too: one check on your device, with no fumbling for a second factor like a one-time code or authenticator app.

A "Sign in with passkey" button now appears next to the password option. Set up one or more passkeys in your personal settings, and use any of them to sign in. Password and MFA sign-in still work too; passkeys are an additional way to authenticate into your account.

Passkeys sync across your devices and through password managers like iCloud Keychain, Google Password Manager, and 1Password, so you can sign in wherever you work.

Every passkey added or removed is recorded in your audit log, so you and your team can see exactly what changed and when.

To enable passkeys, admins should go to

Settings > Early Access

and toggle on the feature to allow their organization’s users to set up passkeys.

You can now set merchant category code (MCC) spend controls at the policy level in Policy Rule Builder. Now you can set a restriction once at the policy level and enforce it automatically across all cards governed by that policy.

You can view MCCs with their descriptions, assign MCCs controls to the policy documentation requirements, approvals, and transaction restrictions sections of the Policy Canvas.

This feature is available to customers using Policy Rule Builder. To enable it, first go to

Settings > Early Access

and toggle on

Enable early access features.

Then visit Policy Setup to add MCC controls.

Brex can now keep vendor details consistent across Brex and QuickBooks Online with near real-time, bidirectional sync. Once a Brex vendor is linked to a QuickBooks Online vendor, changes to supported fields in either system sync automatically. This reduces manual fixes and reconciliation work.

Synced fields include email, website, phone number, 1099 eligibility, and address.

To enable, go to

Settings

Early Access

and toggle on the feature.

To manage, open

Vendors

Manage vendors sync

. There you can turn

Sync vendors from QuickBooks

on and off.

Use Slackbot’s new Brex connector to get answers about your spend and take action on your expenses without leaving Slack. Once connected, you can message Slackbot in plain language to check expenses, find items missing receipts, look up cards and spend limits, and update memos or receipts on your own expenses.

Admins and bookkeepers can also ask company-wide questions about spend, banking, bills, vendors, travel, and accounting records.

Brex in Slack works through Slackbot's connection to the Brex app. The app respects your existing Brex permissions, so you only see and change what your account is allowed to. Additionally, your Slack plan must include Slack AI.

To get started, go to

Settings

Early Access

and toggle on the feature.

You can now create a new general ledger (GL) account in QuickBooks Online without leaving Brex. Access the feature from the Accounting tab by going to QuickBooks settings, opening Entity settings, selecting any GL account dropdown, and choosing “Create GL account.”

This will open a creation drawer where you set the GL name, account type, and an optional account number. The account is created directly in QuickBooks Online and becomes immediately available to use in Brex.

To get started, visit the Accounting tab of your Brex dashboard.

Intelligent finance, wherever you work

Finance questions, whether about vendor invoices, team spend, or receipt follow-ups, tend to sneak into every workflow, from recruiting efforts to marketing events to the engineering tool stack. Until now, answering them meant switching to another tab and yet another login.

Now you can find answers without leaving what you're doing.

Brex MCP brings conversational access to your financial data directly into any tool that supports the Model Context Protocol, including Claude Code, Cursor, Windsurf, and other MCP-compatible clients. Same Brex data, same permissions, no context switch.

Built on Brex intelligence

Inside Brex, AI already handles receipt matching, memo generation, policy enforcement, and review triage. It's how Brex customers maintain ~98% policy compliance on average without constant manual effort.

Brex MCP extends that same data layer to wherever you work. Your Brex permissions carry over, so you only see what you're authorized to, nothing more.

Get started

Add the Brex MCP server URL to your client's configuration, authenticate with your Brex account, and start asking questions.

For setup instructions, available tools, and the full developer reference, see the Brex MCP Developer Documentation.

Brex's QuickBooks Online integration now lets you control whether bill payments sync back to QuickBooks Online. In your QuickBooks sync settings, you can choose to sync all bill payments or none, keeping your bill data accurate without manual cleanup.

There’s also a new "Manage QuickBooks" view within bill pay that provides a settings panel to enable sync, configure required mappings (payment account, AP/card accounts, manual payment handling), and manage preferences.

To enable this feature, ensure you’re opted into Early Access features by going to

Settings >

Early Access and toggling on

Enable early access features.

Then go to

Bills >

Manage QuickBooks > Enable Bill Sync.

There you can configure

Payments to Sync.

Admins can now build auto-invite rules with more conditions using custom fields and reporting lines, making it easier to automatically invite the right employees based on how your team is structured, including consistent rule handling and support for complex team setups. Find it at

Team >
Settings >
Auto-invite.

Note that this functionality is available to Premium and Enterprise plan customers.

To enable this feature, first go to

Settings >
Early Access , and turn on the

Advanced auto-invite rules toggle.

When a bill payment fails, Brex now surfaces the issue clearly on the Bills page and in bill details, as well as by email, with guidance on what went wrong and what to do next. If the issue is external, such as insufficient funds, you can fix it and retry the payment directly. If bill details need to change, you can update and retry from the same flow.

The result is a faster, less frustrating way to recover from failed bill payments, with fewer delays and less duplicate work for AP teams.

Visit the Bills page in your Brex dashboard to explore this feature.

Brex and Zip now let AP teams pay approved invoices with an automatically generated virtual card. Once an invoice is approved in Zip, a unique virtual card is created and locked to the invoice amount, currency, subsidiary, and time window, keeping the payment tied to that specific bill.

Approvers can send the card securely to the vendor or assign a cardholder to pay on their behalf. When the card is used, the transaction is automatically matched to the invoice, synced to your ERP as a bill payment, and the invoice is marked paid.

The result is a faster, more controlled way to pay invoices in Zip with less manual reconciliation.

To enable this feature, reach out to your Brex rep.

Brex now gives accounting teams more control over how NetSuite fields are imported, with a new field-level import flow and built-in permissions check.

During integration setup or reconnect, Brex lists all supported NetSuite fields, including chart of accounts, dimensions, subsidiaries, and currencies, and runs per-field sync checks via NetSuite's APIs.

Fields your NetSuite role can't access are automatically identified so they don't block the overall import. Mandatory fields are clearly enforced, and you can select only the fields you actually want to sync.

Once set up, you can refresh individual fields from the Fields Library without re-importing everything. This helps reduce import time, avoid permission errors, and give you more granular control over how Brex and NetSuite stay in sync.
