What is Order Backlog?

An order backlog is the accumulation of customer orders that have been placed and confirmed but have not yet been shipped or delivered. It represents committed demand that is waiting to be processed through your fulfillment pipeline. A healthy backlog indicates strong demand; an excessive backlog signals fulfillment bottlenecks that risk customer dissatisfaction and cancellations.

Why It Matters

Backlog is a leading indicator of both business health and operational capacity. Growing backlogs can mean your business is thriving—or that your fulfillment operations cannot keep up with demand. Understanding your backlog in terms of both volume and aging is critical for making staffing decisions, prioritizing orders, managing customer expectations, and planning capacity investments.

How It Works

• Backlog Measurement: Track total orders awaiting fulfillment, their dollar value, and their age (how long since the order was placed). Monitor these metrics daily.
• Aging Analysis: Segment the backlog by age buckets (0–1 day, 2–3 days, 4–7 days, 7+ days). Orders aging beyond your SLA threshold need immediate attention.
• Capacity Planning: Use backlog trends to forecast staffing needs. If the backlog is growing consistently, you need more fulfillment capacity.
• Priority Management: Not all backlogged orders are equal. Prioritize by SLA deadline, customer tier, shipping method (expedited first), and channel requirements.
