Every week, Walmart suppliers either protect their business or quietly lose sales (often without realizing it). Monitoring KPIs (Key Performance Indicators) and additional metrics can mean the difference between Walmart growth or losing valuable modular space.
Walmart’s replenishment systems, in-stock scoring, and compliance tracking run continuously. Waiting until month-end to review performance is usually too late to prevent out-of-stocks, chargebacks, or store count losses.
In this article, we’ll go over the weekly metrics and KPIs every Walmart supplier should monitor to stay in control, reduce risk, and show buyers you’re a proactive partner.
Why Suppliers should Prioritize Weekly Monitoring
Walmart doesn’t manage supplier performance on a monthly cadence. Instead, it operates in near real time. Issues like forecast misalignment, OTIF failures, or inventory gaps can escalate in days.
Suppliers who review metrics weekly:
-
-
- Catch problems early before sales are lost
- Reduce recurring chargebacks and deductions
- Maintain stronger buyer relationships
- Avoid surprises during line reviews or performance conversations
-
Think of weekly KPI checks as preventative maintenance for your Walmart business.
The Weekly Walmart Supplier KPI Checklist
At the beginning of the week, review these seven KPIs with your team and make a plan to resolve any issues:
1. In-Stock Percentage (ISP)
Why it matters:
Low in-stock rates directly reduce sales and negatively impact Walmart’s internal scorecards.
What to review:
-
-
- Overall in-stock percentage
- Store-level outliers
- Items with repeated out-of-stocks
-
Tip: A small group of underperforming stores often drives most of the problem.
2. Store Count and Distribution Changes
Why it matters:
Unexpected drops in store count can signal replenishment issues or declining item performance.
What to review:
-
-
- Net change in store count
- Stores that recently went dark
- New stores added but not fully stocked
-
Red flag: Losing distribution without a buyer conversation.
3. On-Time In-Full (OTIF) Performance
Why it matters:
OTIF failures are some of the most common causes of chargebacks and strained buyer relationships.
What to review:
-
-
- On-time percentage
- Fill rate percentage
- Root causes of misses (carrier, lead time, ASN errors)
-
Best practice: Track trends, not just individual failures.
4. Forecast Accuracy and Demand Signals
Why it matters:
Walmart’s replenishment logic depends heavily on forecast alignment.
What to review:
-
-
- Sudden spikes or drops in demand
- Items consistently over- or under-forecasted
- Promotional lift not reflected in forecasts
-
Tip: Forecast issues usually show up before in-stock problems.
5. Chargebacks and Deductions
Why it matters:
Chargebacks compound quickly and are often preventable.
What to review:
-
-
- Newly issued chargebacks
- Repeat deduction codes (Code 27, ASN non-compliance, etc.)
- Patterns by item, DC, or carrier
-
Tip: Fix the root cause, not just the dispute.
6. Fill Rate by Distribution Center (DC)
Why it matters:
Under-serving specific DCs creates regional out-of-stocks.
What to review:
-
-
- Fill rate by DC
- Consistent underperformance in specific locations
- Alignment between demand and DC inventory
-
7. Promotional Readiness (If Applicable)
Why it matters:
Promotions amplify both success and failure.
What to review:
-
-
- Inventory position ahead of promos
- Store coverage vs. expected lift
- Lead time coverage for increased demand
-
The Monday Morning Walmart Supplier Routine
Many successful Walmart suppliers follow a simple weekly cadence:
- Review in-stock percent and store count
- Check OTIF and fill rate exceptions
- Scan new chargebacks and deductions
- Flag urgent issues needing action
- Document trends for buyer discussions
This routine takes less time than fixing problems after they escalate.
Common Mistakes Suppliers Make
As simple as it seems to review KPIs and make adjustments, even seasoned Walmart suppliers run into issues during busier weeks. Try to avoid these mistakes:
1. Reviewing metrics only monthly
Walmart’s replenishment, in-stock scoring, and compliance systems operate continuously, not on a monthly cycle. Waiting until month-end often means issues like out-of-stocks or OTIF failures have already impacted sales, store count, or buyer perception.
2. Looking at totals instead of store-level data
High-level totals can mask serious problems happening in specific stores or regions. A small group of underperforming stores often drives the majority of lost sales. Those issues only become visible when you analyze store-level data.
3. Ignoring small declines until they become major issues
Minor dips in in-stock rates, fill rate, or forecast accuracy are early warning signs. When left unaddressed, these small declines often compound into widespread stockouts, chargebacks, or distribution losses.
4. Focusing only on sales, not operational health
Strong sales can hide operational issues such as poor OTIF performance or forecast misalignment. Walmart ultimately prioritizes reliable execution, and suppliers who ignore operational KPIs risk long-term performance declines even if short-term sales look strong.
Most Walmart issues don’t appear overnight. They build quietly.
