Choose your setup type
The BRM connect dialog asks which setup you have. Pick based on how your AWS is structured:
If you’re not sure, check whether your AWS bill is consolidated: if multiple accounts roll up into one bill, you have an AWS Organization, and the account that owns that bill is the management account.
What you’ll need
Before you connect
Two account-level settings must be on in the account you’re connecting (for an AWS Organization, the management account). Both are one-time toggles:- Enable Cost Explorer. In the AWS console, open Cost Explorer from the Billing console. If it has never been opened, AWS takes up to 24 hours to prepare your data — do this first.
- Activate IAM access to billing information. In Account settings (in the Billing console), enable IAM user and role access to billing information. Without this, no IAM role — including BRM’s — can read billing data, regardless of its permissions.
Connect a single AWS account
Step 1: Open the AWS integration in BRM
In BRM, click your profile in the lower-left corner, then Integrations. Find AWS and click Connect. Leave the setup type on Single AWS account.Step 2: Launch the CloudFormation stack
Sign in to the AWS console for the account you want to connect (an admin who can create IAM roles), then click Launch CloudFormation stack in the AWS console in the BRM dialog. The stack opens with everything pre-filled — you don’t need to change any parameters. Check the acknowledgment box (“I acknowledge that AWS CloudFormation might create IAM resources with custom names”) and click Create stack.Step 3: Copy the role ARN
When the stack finishes (usually under a minute), open its Outputs tab and copy the RoleArn value. It looks likearn:aws:iam::123456789012:role/BRMIntegrationRole.
Step 4: Paste the ARN into BRM
Back in the BRM dialog, paste the role ARN and click Create Integration. BRM verifies it can assume the role and confirms the connection.Connect an AWS Organization
Step 1: Choose organization mode
In the BRM connect dialog, switch the setup type to AWS Organization (multiple accounts).Step 2: Launch the stack in your management account
Follow the same stack launch as a single account, but sign in to your management account — the account that owns your consolidated bill. This matters: BRM verifies at connect time that the role really is in the management account, and will tell you if it isn’t. Copy the RoleArn from the stack’s Outputs tab, paste it into BRM, and click Create Integration. The management account’s billing data covers spend for every account in your organization, so this single connection is already complete for cost tracking.Step 3 (optional): Cover member accounts with a StackSet
Some data only exists inside each member account — most importantly, AWS Marketplace agreements purchased from that account. To cover them, create a CloudFormation StackSet from the management account. It deploys the same read-only role to every member account, and automatically to new accounts as they join your organization. The BRM dialog shows the exact commands with your values pre-filled. You can run them now or any time later — spend tracking works either way. ℹ️ If any account already has theBRMIntegrationRole from an earlier standalone stack, exclude it from the StackSet targets (or delete its standalone stack first) — otherwise the deployment to that account fails because the role name already exists.
What BRM reads
The role is strictly read-only and scoped to procurement and cost data:- AWS Marketplace agreements (including private offers), their terms, and contract documents
- Cost and spend data from Cost Explorer, including committed spend such as Savings Plans and Reserved Instances
- Amazon Bedrock usage and per-model spend
- Invoices, budgets, and organization account names
Common mistakes
- Connecting a member account in organization mode. Organization mode requires the management account. If BRM reports the role is in a member account, either launch the stack in the management account instead, or switch to single-account mode for that account.
- Skipping the billing toggles. If Cost Explorer was never enabled or “IAM access to billing information” is off, the connection succeeds but spend data can’t be read. Both toggles live in the Billing console of the connected account.
- The stack fails with a role-name error. The account already has a
BRMIntegrationRolefrom an earlier launch. Delete the old stack first (CloudFormation → Stacks), then relaunch. - Connecting the wrong account. Marketplace agreements are only visible from the account that purchased them. If your subscriptions were bought in a different account, connect that account too (or cover it with the StackSet).
- Deleting the stack or role after connecting. This immediately cuts off BRM’s access — which is exactly what to do if you ever want to disconnect, but do it deliberately.
