Expense Approval Workflow

Every expense is logged automatically, with amounts over $500 routed to a manager for approval — smaller ones are auto-noted to finance without blocking anyone's day.

Automation flow

How it works

  1. 1An employee submits an expense.
  2. 2It's logged with Status = Pending.
  3. 3If the amount is over $500, the finance manager gets an email to review and approve.
  4. 4If it's $500 or under, finance just gets a lightweight Slack note — no approval bottleneck for routine expenses.

A rough estimate based on what you enter above — not a guarantee. Actual time saved depends on your process.

Make it yours

  • Adjust the $500 threshold to match your organization's actual approval policy.
  • Add a second, higher threshold (e.g. $2000) that requires two approvers instead of one.
  • Auto-reimburse small, pre-approved categories (e.g. under $50 for office supplies) with zero manual review at all.
