Fill Rate
Fill rate is the share of wholesale orders shipped complete and on time — whether a brand can meet demand without backorders or substitutions.

What is fill rate?
Fill rate is the percentage of wholesale customer orders that are shipped complete and on time — without backorders, partial shipments, or substitutions. In apparel merchandising, fill rate is a critical service-level metric that directly affects retailer relationships, reorder likelihood, and brand reputation in wholesale channels.
Fill Rate = (Units Shipped on Time and Complete ÷ Total Units Ordered) × 100
A fill rate of 95% means that for every 100 units ordered by retail partners, 95 shipped as requested. The remaining 5 units were either backordered, cancelled, or shipped late.
Why fill rate matters in apparel
Wholesale apparel operates on tight delivery windows tied to seasonal floor sets. A retailer planning a Spring launch needs inventory on the floor by a specific date. Missed or incomplete shipments create cascading problems:
- Lost floor space: Retailers allocate shelf and rack space in advance. Missing units mean empty fixtures or substitutions from competitors.
- Chargebacks: Major retailers impose financial penalties for late or incomplete shipments under their vendor compliance programs, and the deductions come straight off the invoice.
- Reduced future orders: Retailers track vendor fill rates and reduce open-to-buy allocation for brands that consistently underperform.
What drives fill rate performance
Fill rate is the downstream result of the entire planning and production chain:
- Accurate demand forecasting ensures production quantities match anticipated orders
- Production lead time management prevents delays from raw material shortages or factory bottlenecks
- Inventory positioning ensures finished goods are in the right distribution center when orders arrive
- Size and color completeness — a partial shipment missing key sizes counts against fill rate even if total units are close to target
There is no public, audited benchmark for apparel wholesale fill rates. A workable internal target is 95% or higher: retailer vendor scorecards track fill rate account by account, and a target much below that concedes chargebacks and floor space before the season starts.
