The short answer
An order-accuracy target is an operational goal; a contractual fulfillment error allowance defines how errors affect commercial remedies. A target such as 99.x% does not tell you which errors count, who pays or when credits begin. Judge an allowance by its definitions, measurement and remedies—not its percentage alone.
Define a qualifying error
A wrong customer-provided address is not automatically a 3PL error. Confirm which party supplied instructions and whether the warehouse followed them. Define exclusions, evidence and the claims process before a dispute occurs.
- Wrong SKU, wrong quantity or a missing item attributable to the warehouse.
- An incorrect warehouse-applied label, packaging choice or shipment preparation.
- A late shipment directly caused by the warehouse where a defined SLA applies.
How the allowance is calculated
Specify the denominator: orders shipped, lines picked, units handled or another base. Define the monthly, quarterly or other measurement period, rounding and whether unused allowance resets or carries forward. Different denominators produce different results from the same percentage.
Hypothetically, 1,000 qualifying orders × 0.5% = 5 orders. This is arithmetic, not a recommended allowance. If there are 8 qualifying errors, a deductible structure might provide remedies only for 3 above the allowance; a trigger structure might activate remedies for all 8 once exceeded. The contract determines the result.
What should not automatically be grouped together
- Fulfillment errors: incorrect execution of an order or an applicable shipping SLA.
- Unexplained inventory shrink: a stock variance requiring reconciliation.
- Documented warehouse-caused inventory loss or damage: potentially a separate liability claim.
- Inbound shortages: differences attributable to suppliers or inbound delivery.
- Customer instruction or inventory-record errors.
- Carrier loss after the warehouse properly tenders a shipment.
For stock discrepancies, see Inventory shrink in a 3PL; a general shrink allowance should not automatically absorb known warehouse-caused loss.
Remedies and repeated failures
Possible negotiated remedies include fulfillment-fee credits, reshipment fulfillment cost, reasonable replacement postage, SLA credits, escalation procedures or termination rights for repeated failures. Specify documentation, claim deadlines, credit timing and which costs are eligible.
Product replacement is not automatically appropriate for every fulfillment error: a mispick may be recoverable without permanent inventory loss. Physical inventory loss or damage may be governed by a separate liability section with its own valuation and caps. Avoid assuming one remedy fits every cause.
Commercial interpretation
This is a commercial interpretation, not legal advice. There is no universally correct allowance structure; have important wording reviewed by a qualified professional.
