Backorder vs Expedite Decision
Compare true total cost of backordering versus expediting a short order, including the flat minimum expedite charge a per-unit-rate comparison misses.
Backorder
Expedite
Backorder$425 saved
Total backorder cost$200
Total expedite cost$625
How this works
When an order can't be fulfilled on time, expediting looks attractive if only its per-unit rate is compared against the backorder cost, but expedited freight usually carries a flat minimum charge regardless of quantity.
Key terms
- Expedite fixed cost: a flat minimum charge for expediting, independent of how many units are short.
Assumptions
- Backorder cost and expedite rates are known and stable for this shortfall
Limitations
- Single shortfall event, not a full logistics-mode optimization
Sources
Standard fulfillment cost-tradeoff practice (backorder versus expedite).
Worked example
The expedite per-unit rate ($25) is well below the backorder per-unit cost ($40), a rate-only comparison would pick expedite. But a $500 flat expedite charge on only 5 units pushes its real total to $625, well above backorder's $200, flipping the verdict.
Common use cases
- Deciding how to handle an order that missed its cutoff
- Comparing backorder and expedite cost for a small versus large shortfall
- Avoiding an expedite decision driven by rate alone
