Brex users can now manage a legal name for compliance and a preferred name for display, with dedicated settings for each, and set a per-transaction maximum on a User Limit so single purchases over the threshold are automatically blocked. Other early-access additions include bulk NetSuite amortization date edits in the Accounting journal, faster send-to-review and ERP export actions, refreshed Wallet and navigation in the mobile app, more bills search and grouping options, and a cleaner Support Hub panel.
Brex's Summer Release 2026 graduates more than 30 features from Early Access to general availability, spanning ERP integrations and accounting mappings, expense receipt management, card spend limits and policy rules, and passkey sign-in. Brex data is now accessible in ChatGPT, Claude, and Slack via MCP, alongside a redesigned Accounts page and navigation.
General ledger codes can now be created in QuickBooks Online directly from Brex.
A new receipt view in the Wallet lets users see all their receipts and assign unmatched ones to expenses, making it easier to create reimbursements or match receipts sent via text, email, or WhatsApp. The feature is available via Settings > Early Access by toggling on early access features.
Brex vendors linked to QuickBooks Online vendors now sync supported fields bidirectionally in near real time, including email, website, phone number, 1099 eligibility, and address. Enable it under Settings > Early Access, then manage sync from Vendors > Manage vendors sync.
Merchant category code spend controls can now be set at the policy level in Policy Rule Builder and enforced automatically across all cards governed by that policy, with MCCs assignable to approval, documentation, and transaction restriction sections of the Policy Canvas. Available to Policy Rule Builder customers after enabling early access features in Settings.
Users can now authenticate with a passkey instead of a password and MFA, with passkeys syncing across devices via iCloud Keychain, Google Password Manager, and 1Password. Password and MFA sign-in still work, and admins must toggle the feature on under Settings > Early Access to let users set up passkeys.
Users can query Brex data directly in Slack.
Brex Assistant notifications for completed actions like memo or receipt generation now appear in the main notifications feed instead of only the standalone Brex Assistant tab, and notifications are grouped by creation date. The standalone tab is being deprecated; enable the change via Settings > Early Access under "Automatic experience updates."
"Limit per user" is renamed to "Spend limit group" across Cards and Limits, and the creation flow now asks upfront whether to use a single shared spend limit or a group of individual spend limits. The change is behind the "Automatic experience updates" toggle in Settings > Early Access.
Employee card limits can now have their currency changed even after spend has already occurred, with Brex updating the limit currency and related expenses automatically instead of requiring expenses to be moved out of the limit and back in. The feature must be enabled under Settings > Early Access, and the currency is changed from the card's Edit card screen.
Custom-rule extended-field filters now accept multiple values in a single filter, so NetSuite Department = Engineering / Sales / HR can be one rule instead of one rule per value. Configure it under Accounting > Manage Automations > Custom rules.
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.
Admins setting up policies in Policy Rule Builder now have two new options specific to purchasing cards:
Custom rules in Brex now support "is not" filters, including "is not empty." When building rules in Accounting > Manage Automations > Custom rules, you can exclude specific field values or require that a field contain any value at all. This gives accounting teams more…
Accounting admins can now enable a per-field toggle that appends the ERP field value ID to the display name in Brex. This makes it easier to distinguish values that share the same name but different IDs (for example, multiple projects or classes with identical names).
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.
You can now connect your ERP earlier in the Brex onboarding flow, so Brex can start reading your GL structure and transaction history before accounting setup begins. QuickBooks Online, Xero, and Puzzle are supported via a standard OAuth flow directly from the onboarding…
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…
