Reviewer workflows are an optional feature that must be enabled at the account level before reviewers can be assigned to cards.
To enable reviewer workflows:
1. Go to Expense configurations in your Mamo dashboard
2. Toggle on Reviewer workflows
Once enabled, reviewers can be assigned to cards during card issuance or added to existing cards at any time. Reviewer workflows can be disabled at any time from the same page, which removes reviewer requirements across the entire account.
Only users with permission to configure expense accounting rules and integrations can access Expense configurations.
Assigning reviewers to cards
Reviewers are assigned at the card level — each card can have one or more reviewers assigned, and those reviewers are responsible for expenses made on that specific card.
When issuing a new card
As part of defining spend policies during card creation, the card issuer can assign reviewers directly. This is done in the Reviewers section of the card setup flow.
On existing cards
Reviewers can be added or updated on cards that have already been issued.
To manage reviewers on an existing card:
1. Navigate to the Card details page
2. Open the Expense reviewers section, or use the options menu on the card details page
3. Add, edit, or remove reviewers as needed
Note: Adding a reviewer to a card with existing transactions applies only to future transactions. Past expenses on that card are not affected.
Only users with permission to edit or manage spend policies on a card can add or change reviewers.
Reviewing expenses
As an expense reviewer, you are responsible for assessing expenses made on the cards you are assigned to. You will receive an email notification when an expense is pending your review.
Expenses requiring your review are available in the Team transactions tab on the Transactions page. This tab is visible if you are assigned as a reviewer on at least one active card. It shows all expenses on those cards that require — or will require — your input.
Approving an expense
1. Open the expense from your Team transactions tab
2. Review the details, category, description, and any attached receipts
3. Select Approve
No further action is required after approving.
Declining an expense
1. Open the expense from your Team transactions tab
2. Review the details
3. Select Decline
4. Provide a reason for declining
Declined expenses signal to the employee and expense admin that the expense does not align with company policy. Further actions (such as reimbursement) are managed outside of Mamo for now.
