Expense Report Tracker Template — Who's Owed Money, and Did Any of It Break Policy, Answered Automatically

Expense reports are a tax on everyone's time. Employees hate filing them, managers hate reviewing them, and finance hates chasing both. The real problem is not the paperwork — it is that policy violations sit undetected in a queue until someone manually compares each line item against a limit table that lives in a different document.

The OpenSource AI Pro Expense Report Tracker automates the painful parts. Formula flags instantly identify expenses that exceed policy limits. A pending approval queue surfaces reports waiting for action. Stamp-based alerts notify approvers exactly once per new submission, and a scheduled digest keeps finance informed without anyone having to ask. Self-hosted on Baserow, zero per-seat pricing, unlimited users.

Key Features

• Over_Policy_Limit Flag — Each expense line item runs through a formula that compares the amount against the policy limit for its category. Meals over $75? Flagged. Travel over the per-diem? Flagged. The flag is live — it updates the instant an expense is entered or a policy limit changes.

• Pending Approval Queue — A filtered view surfaces every expense report in "Submitted" status, sorted by submission date. Managers see exactly what needs their attention without digging through a full list.

• Stamp-Based Exactly-Once Alerts — When an employee submits an expense report, an event-triggered automation emails the assigned approver. The _notified_submitted stamp ensures one notification per submission — no duplicates if the report is edited, no missed alerts if the system restarts.

• Scheduled Expense Digest — A daily automation collects all pending reports, all policy-flagged items, and all reports approved-but-not-yet-reimbursed, then sends a summary to the finance team. One email replaces a dozen status checks.

• Category-Based Policy Limits — Policy limits live in their own table, linked to expense categories. Update a limit once and every current and future expense in that category checks against the new number.

• Reimbursement Tracking — Track each report through Submitted, Approved, Rejected, and Reimbursed. The reimbursement date field closes the loop so employees know when to expect payment.

How It Works

Formula Flags. The Over_Policy_Limit field is a formula that looks up the policy limit for the expense's category and compares it against the line item amount. If the amount exceeds the limit, the flag is true. A Total_Flagged_Amount rollup on the report level sums all flagged items so approvers can see the total policy exposure at a glance.

Event-Triggered Alerts. A Baserow automation monitors the report status field. When a report transitions to "Submitted," the automation sends an email to the linked manager with the report total, number of line items, and whether any items are policy-flagged. The _notified_submitted stamp records that the alert was sent. If the report is returned for revision and resubmitted, a new stamp cycle begins.

Scheduled Digest. A second automation runs daily. It queries three things: reports pending approval (with age in days), line items flagged for policy violations, and reports approved but not yet reimbursed. The digest lands in the finance lead's inbox every morning with clear action items.

Who It's For

• Finance teams at companies with 20-500 employees who need policy enforcement without expensive expense management software
• Office managers handling expense processing alongside other responsibilities who need the system to surface problems automatically
• Startup operations leads who want structure and policy compliance without paying $8-15/user/month for Expensify or Brex
• Nonprofits and grant-funded organizations where expense policy compliance is an audit requirement, not a suggestion
• Consulting firms with project-based expense tracking where costs must be categorized and policy-checked before client billing
