The Costco Vendor Scorecard for CPG Brands 2026: OTIF, ASN Accuracy, Chargeback Defense and How to Stay Green
Score well and you build trust, earn better shelf placement, and scale smoothly. Score poorly and you're paying fines, losing purchase orders, and defending your brand's position in every buyer meeting.
That assessment of vendor scorecard performance applies with specific force to the Costco channel — where the buyer-driven model concentrates every commercial consequence of scorecard performance into a single relationship. At Walmart, a poor OTIF score triggers an automated fine through the compliance system. At Costco, a poor operational performance record degrades the human relationship with the buyer who controls every commercial decision about the brand's program — assortment, promotional placement, roadshow scheduling, and the program's long-term expansion or contraction.
Understanding Costco's specific vendor performance metrics — what is measured, how it is measured, what the thresholds are, and how to dispute the chargebacks that inevitably arrive — is foundational operational knowledge for any CPG brand in the Costco channel.
The brands that maintain consistent green-status performance across the key metrics are the brands whose buyer relationships generate expansion conversations rather than compliance conversations.
This guide covers the complete Costco vendor scorecard picture for CPG brands in 2026 — every metric that matters, the specific mechanics that determine pass or fail, the chargeback dispute process, and the operational system that maintains green-status performance without requiring heroic effort at the individual shipment level.
The OTIF Metric: The Most Consequential Single Scorecard Number
What OTIF Means at Costco
OTIF — On-Time, In-Full — is the supply chain performance metric that Costco, like most major retailers, uses as the primary indicator of vendor delivery reliability. Unlike some retailer OTIF programs that use different terminology (Target calls it On Time Fill Rate, Kroger uses ORAD), Costco enforces delivery accuracy through the ASN-driven delivery accuracy framework — where the ASN (Advance Ship Notice) submitted before shipment is the contractual commitment that defines both the on-time and in-full dimensions of the delivery assessment.
The OTIF metric's specific operational definition at Costco: a shipment is on-time if it arrives at the specified depot within the delivery window defined by the purchase order's required delivery date. A shipment is in-full if the quantity of cases received at the depot matches the quantity committed in the purchase order and confirmed in the ASN. Both conditions must be met simultaneously for the shipment to pass.
The OTIF Multiplication Math: The Number That Surprises Most Brands
The most commonly misunderstood dimension of OTIF is the mathematical structure of the composite score. OTIF is not an average of the on-time rate and the in-full rate. It is the product of the multiplication of the two rates.
If the on-time rate is 90 percent and the in-full rate is 90 percent:
OTIF = 0.90 × 0.90 = 81 percent
The composite OTIF score is 81 percent — not 90 percent. That 9-percentage-point gap from the intuitive average has significant commercial consequences in channels where compliance thresholds are set at 85 to 98 percent.
For Costco specifically: the target OTIF range that maintains green-status scorecard performance is generally above 95 percent — meaning both the on-time and in-full dimensions need to individually exceed 97 to 98 percent to produce a composite OTIF above 95 percent.
The practical implication for CPG brands: a brand that is hitting 93 percent on-time and 94 percent in-full believes its delivery performance is good — but the composite OTIF of 87.4 percent (0.93 × 0.94) is below the threshold that maintains green-status performance in most Costco vendor assessments.
The On-Time Dimension: What Controls It
The on-time component of OTIF is controlled by three operational variables:
Production timing. The product must be available for carrier pickup at the moment the carrier is scheduled to collect it — not the day after, not three hours late. A production run that finishes 12 hours behind schedule creates a carrier pickup delay that cascades into a late delivery at the depot.
Carrier appointment scheduling. The depot delivery appointment must be scheduled within the purchase order's required delivery date window, and the carrier must execute the delivery within the scheduled appointment time. A carrier who arrives outside the appointment window is refused receiving, creating an OTIF failure regardless of whether the product was ready on time.
Transit time accuracy. The transit time from the shipping facility to the depot must be calculated accurately — accounting for the carrier's lane-specific transit time, the depot's receiving hours, and any regional or seasonal disruption factors. A brand that consistently underestimates transit time is building OTIF failures into the logistics model rather than addressing them operationally.
The In-Full Dimension: What Controls It
The in-full component of OTIF is controlled by the accuracy of the fulfillment execution against the purchase order's line-item specifications.
The most common in-full failure modes:
Short shipment: the carrier picks up fewer cases than the purchase order specifies because the production run did not complete, because the warehouse pull was inaccurate, or because cases were allocated to a different order by mistake.
Date code compliance failure: cases that meet the quantity specification but fail Costco's minimum remaining shelf life requirement are refused at receiving — creating an effective short shipment even if the physical quantity was correct.
Wrong item: a case of the wrong SKU — wrong flavor, wrong size, wrong configuration — included in the shipment counts as a non-conforming unit that is excluded from the in-full calculation.
The ASN: The Document That Defines Compliance
What the ASN Is and Why Its Accuracy Is Non-Negotiable
The ASN (Advance Ship Notice) is the electronic document — transmitted through the EDI 856 transaction set — that notifies Costco's depot receiving system of the specific contents of an inbound shipment before the shipment arrives. The ASN must be transmitted two to four hours before carrier pickup — Costco's specific transmission requirement that allows the depot's receiving system to prepare for the inbound load.
The ASN accuracy requirement: every element of the ASN must match what physically arrives at the depot. The case quantity per line item, the SSCC-18 pallet identifiers, the item identifiers (GTIN-14), the purchase order number, and the lot/date code information must match the physical shipment exactly.
The consequences of ASN inaccuracy:
ASN submitted late (after carrier pickup): $50 to $250 per incident chargeback. The late ASN chargeback is assessed regardless of whether the physical shipment was perfect — the administrative failure of late transmission carries its own penalty.
ASN quantity mismatch (ASN says 100 cases, depot receives 97): the three-case discrepancy generates both an in-full failure for the OTIF calculation and a receiving discrepancy that requires administrative resolution. Unresolved receiving discrepancies accumulate as invoice deductions that the vendor must dispute.
SSCC-18 mismatch (pallet label barcode does not match ASN): the depot's receiving scan cannot match the arriving pallet to the ASN record, creating a receiving exception that generates a compliance chargeback and delays the depot's receiving process.
Building the ASN Accuracy System
The ASN accuracy system that maintains above-99-percent ASN accuracy across a high-volume Costco program has three components:
System integration: the WMS (Warehouse Management System) that generates the physical pick and pack is directly connected to the EDI system that generates the ASN — so the ASN reflects what was actually picked, not what was supposed to be picked. A WMS that requires manual data entry between the physical pick and the ASN generation creates the human error opportunity that drives ASN inaccuracy.
Pre-shipment verification: a physical audit of the loaded trailer against the ASN before the carrier departs — confirming that the case count, the SKU mix, and the SSCC-18 pallet labels match the ASN exactly. This five-to-ten-minute verification eliminates the ASN mismatches that are discovered only at the depot receiving dock.
Transmission timing discipline: the ASN transmission is a scheduled operational event — triggered by the carrier pickup notification, completed within 30 minutes of pickup confirmation, and never transmitted after the carrier is already en route. The brand that treats ASN transmission as a background administrative task rather than a time-critical operational requirement will accumulate late ASN chargebacks.
Chargeback Types and the Dispute Process
The Chargeback Landscape at Costco
Chargebacks at Costco arise from compliance failures across the full range of vendor obligations — delivery timing, ASN accuracy, pallet specification, label compliance, and product quality. The chargeback amounts vary by failure type:
Chargeback Type | Typical Amount | Root Cause |
Late ASN | $50-250 per incident | ASN transmitted after carrier pickup |
SSCC-18 label non-compliance | $50-250 per incident | Label missing, unreadable, or misplaced |
Pallet configuration | $100-500 per incident | Height, weight, or stretch wrap specification failure |
Routing non-compliance | $200-500 per incident | Unapproved carrier or routing guide violation |
Short shipment | Per-unit cost × shortage quantity | In-full failure |
Date code non-compliance | Per-unit cost × refused quantity | Below minimum shelf life requirement |
For mid-size CPG suppliers, annual chargeback exposure can easily reach $50,000 to $500,000 or more without a systematic compliance management program. The brands that treat chargebacks as an unavoidable cost of doing business with Costco are not operating a compliance management program — they are operating a chargeback accumulation program.
The Chargeback Dispute Process
Industry estimates suggest 15 to 30 percent of chargebacks can be successfully reversed with proper documentation and timely dispute submission. The dispute window at most retailers — and at Costco specifically — is a defined period after the chargeback notification, typically 30 to 90 days. A chargeback that is not disputed within the window becomes permanent.
The successful chargeback dispute requires three elements:
Specific, documented evidence that the compliance failure did not occur as assessed. For an OTIF late delivery chargeback: the carrier's delivery confirmation timestamp showing on-time arrival at the depot dock, the depot appointment confirmation showing the correct appointment time, and the BOL showing the departure time from the shipping facility. If the evidence shows the shipment arrived on time, the chargeback is disputable.
Evidence that the failure was caused by a factor outside the vendor's control. The most commonly successful category of OTIF dispute: carrier delivery errors where the vendor's logistics records show on-time tender to the carrier, but the carrier failed to execute the delivery within the required window. Costco's compliance system is not designed to penalize vendors for carrier failures — but the vendor must proactively document and submit the carrier failure evidence to trigger the dispute review.
Dispute submission within the defined window. A valid chargeback dispute submitted outside the dispute window is not reviewable. The dispute management process requires weekly review of chargeback notifications — not monthly review that allows the dispute window to close before the brand responds.
The Dispute Priority Framework
Not all chargebacks are worth disputing. The dispute effort investment should be allocated based on the chargeback amount relative to the effort required to build the dispute case:
High priority (always dispute): chargebacks above $500 where the evidence clearly supports the vendor's position. These disputes generate the most financial recovery for the dispute effort invested.
Medium priority (dispute with standard evidence package): chargebacks of $100 to $500 where standard shipping records support the vendor's position. The standard evidence package (BOL, carrier delivery confirmation, ASN transmission timestamp) is available from the logistics system without significant investigation effort.
Low priority (evaluate case-by-case): chargebacks below $100 where building a specific dispute case requires significant investigative effort. The breakeven analysis should determine whether the expected recovery exceeds the internal labor cost of building the dispute.
The Green/Yellow/Red Framework: Understanding Scorecard Status
Green Status: The Commercial Asset
Green scorecard status across all key metrics — OTIF above 95 percent, ASN accuracy above 98 percent, invoice match rate above 95 percent, pallet compliance above 99 percent — communicates to the buyer that the brand is a reliable operational partner whose program generates commercial value without administrative burden.
The specific commercial benefits of green-status performance: the buyer who does not spend meeting time addressing compliance failures with a vendor has more productive buyer relationship capacity to invest in the program's commercial growth. The brand that arrives at the quarterly business review with a green scorecard is arriving to discuss expansion. The brand that arrives with a yellow or red scorecard is arriving to explain failures.
Yellow Status: The Warning Signal
Yellow scorecard status — one or more metrics below the green threshold but not yet at the level that generates systematic commercial consequences — is the status that requires immediate corrective action before it degrades to red.
The specific yellow-status response: identify the specific root cause of the metric underperformance, develop a corrective action plan with specific timeline and accountability, and communicate the corrective action plan to the buyer proactively — before the buyer raises the performance concern. The brand that brings the problem and the solution to the buyer simultaneously is demonstrating the operational self-awareness that builds buyer trust.
The brand that waits for the buyer to raise the concern is demonstrating the reactive posture that erodes it.
Red Status: The Existential Threat to the Program
Red scorecard status — consistent underperformance across multiple metrics, OTIF below 85 percent, systematic chargeback accumulation without dispute activity — is the commercial signal that the buyer is building the documentation case for program reduction or elimination.
The red-status recovery requires not just operational improvement but buyer relationship repair: a specific in-person meeting with the buyer (not a phone call, not an email) where the brand's leadership presents the specific root cause analysis, the specific corrective actions already implemented, the specific timeline for metric improvement, and the specific accountability structure that ensures the correction is sustained rather than temporary.
