As competitiveness becomes more and more fierce, what can suppliers do to get a leg up? Just like we should always be aware of our credit score, the same can be said for vendor performance. Do you have any idea how your business is perceived by your customers? If not, this blog will help you implement strategies for identifying vendor improvement areas through scorecards!
A supplier scorecard (vendor scorecard) is part of a vendor management program and is used to measure and track performance over time, determining how valuable your partnership is to your customer. The better your score, the more business you’ll secure—and the stronger your long-term supplier relationships with retailers will be.

How are Vendor Scores Determined?
There are typically four different steps in tracking supplier performance and determining a vendor score:
1. Identify Key Performance Indicators (KPIs)
The vendor evaluation process begins at the contract stage—or even during the onboarding or RFP process. Retailers outline service level agreements (SLAs) and key expectations that new vendors must meet. Many retailers provide a vendor scorecard template that outlines exactly how performance will be measured, including ASN timeliness, invoice accuracy, and order fulfillment rates. According to Vendorful, the four most relevant KPIs for a performance scorecard include:
- Product quality
- Vendor responsiveness and communication
- On-time delivery and procurement
- Price variance and cost control
2. Define Measurable Metrics
Now that you have the KPIs, how will you measure them? Common scorecard metrics used by procurement teams include:
- On-time advance shipping notices (ASNs) and timeliness
- Invoice accuracy, order accuracy, and pricing alignment
- Order fulfillment rates and backorder handling
3. Prioritize Performance Metrics Based on Business Goals
What weight will you assign to each metric?
What is more important?
Each company will have different priorities, whether it’s responsiveness, strategic sourcing or price variance.
4. Strategies for Identifying Vendor Improvement Areas Through Scorecards
Based on your performance data, you must implement strategies for identifying vendor improvement areas through scorecards. You’ll have a good idea which customer relationships are at-risk, allowing you to take corrective action and avoid disruptions before losing their business.
How Does a Good (or Bad) Vendor Score Affect Your Business?
Once your customer has amassed information over time, you can expect many scenarios to unfold. If you are perceived as a “good” supplier, your customer may come to you for a long-term contract to lock in pricing. Or if you are a “bad” supplier, your customer may reduce your distribution down to a smaller market.
High Vendor Scores Lead to Greater Opportunities
Continuous improvement leads to healthier relationships. Suppliers with strong vendor scores may receive:
- Long-term contracts to lock in pricing and ensure continued business
- Priority in product placement on retailer websites or in stores
- Larger purchase orders as retailers consolidate business with top-performing vendors
Low Vendor Scores Can Lead to Reduced Orders or Termination
Supply chain inefficiencies lead to strained relationships. A poor vendor score can have severe consequences, such as:
- Reduced distribution—a supplier that previously stocked 1,000 stores may be cut down to just 50
- Fewer contract renewals as retailers seek more reliable suppliers
- Lower revenue due to missed sales and weakened relationships
As supply chain technology gets more sophisticated, we can expect retailers to take a much more strategic approach to the sourcing and procurement process. Vendor score cards are just one way in which retailers are doing just that. And the retailer that reduced distribution for the underperforming supplier? They now have more money to spend on the “good” suppliers. It’s a win-win for both the retailer and the “good”’ suppliers as well as a proven method for managing vendor relationships.
The Value of Data Integrity
A vendor score card is only as reliable as the data used to calculate it. If your customer is using inaccurate or incomplete data, it can lead to unfair assessments and lost business.
How can you ensure that your customer is using good data? It goes without saying, anecdotal data does not count. Our EDI visibility platform, VelociLink™ EDI Analytics, offers human readable insight and analytics that come directly from your EDI records, giving you access to up-to-the-minute information and a single version of the truth.
Communication and collaboration are key. Communicate with your retailers easily and efficiently via the collaboration tool. If an invoice fails on the retailer side, VelociLink™ EDI Analytics will provide information on the exception and via the collaboration tool, teams can make data driven decisions and easily resolve the issue (see figure 1 below). You can view the entire lifecycle of an order, helping to eliminate gray areas and promote transparent communication.
How to Improve Your Vendor Score & Strengthen Retailer Relationships
What are the key takeaways for suppliers looking to leverage vendor scores to keep their best customers happy? Meet or Exceed SLAs: First and foremost, ensure that you are meeting SLAs. Just because you won the contract does not mean that you can get complacent.
Monitor KPIs & Adjust as Needed: Keep track of those KPIs and communicate regularly with your customers to stay on the leaderboard.
Strengthen Customer Relationships: Other advantages to keeping a higher score can also include non-monetary incentives such as unlimited meetings with your vendor manager and category leader, such was the case with former Amazon Platinum Merchants. These sellers of course, had Amazon sales in the 7-figure range. But for vendors in lower score categories, they might have had only one meeting per year, severely impeding opportunities to foster the relationship.
This program was replaced by Amazon a few years ago, but it clearly illustrates that higher vendor scores not only mean better relationships, more orders (and profit), but perks you may not have even considered.
Best EDI Practices to Proactively Improve Vendor Scorecards
Understanding how vendor scorecards are calculated is only half the battle. The real advantage comes from preventing the errors that negatively impact your score before they ever reach your retail partner.
Because most scorecard penalties are driven by EDI transaction failures—such as inaccurate invoices, late ASNs, or mismatched data—suppliers must take a proactive, system-driven approach to EDI execution.
Below are key EDI best practices that help suppliers consistently meet retailer expectations and protect their vendor performance.
Implement Pre-Transmission Data Validation for EDI Documents
One of the most common causes of scorecard penalties is invoice inaccuracy—especially pricing mismatches, missing fields, or incorrect quantities in EDI 810 invoices.
Instead of relying on downstream rejection reports, suppliers should validate EDI data before transmission.
A strong validation layer should:
- Cross-check invoice pricing against purchase orders (EDI 850)
- Ensure required fields (terms, dates, item details) are populated correctly
- Validate data formats against retailer-specific requirements
By catching errors before they are sent, suppliers can significantly reduce rejected invoices, improve invoice accuracy metrics, and avoid costly chargebacks.
Automate ASN (856) Creation Directly from the ERP
Advance Ship Notices (ASNs) are one of the most heavily weighted components of vendor scorecards. Late, inaccurate, or missing ASNs can immediately impact your standing with retailers.
Manual ASN creation introduces risk—especially around timing, labeling, and shipment details.
Best practice is to:
- Automatically generate EDI 856 documents directly from ERP shipment data
- Ensure carton, pallet, and item-level details are system-driven—not manually entered
- Trigger ASN transmission in real time as shipments are confirmed
This tight integration ensures that ASNs are accurate, timely, and aligned with physical shipments—improving on-time delivery rate metrics and reducing compliance violations.
Establish Real-Time Exception Monitoring and Alerts
Even with automation in place, issues can still occur. The difference between high- and low-performing suppliers is how quickly those issues are identified and resolved.
Instead of waiting for retailer notifications, suppliers should implement real-time visibility into their EDI transactions.
This includes:
- Automated alerts for failed or rejected EDI documents
- Visibility into document status across the full transaction lifecycle
- Immediate access to error details for rapid resolution
With tools like VelociLink™ Analytics, suppliers can monitor EDI activity as it happens, collaborate with partners and stakeholders, and resolve exceptions before they escalate into scorecard penalties. Again, having access to a single source of the truth allows for making informed decisions.
Standardize EDI Processes Across All Trading Partners
Inconsistent processes across retailers create complexity—and complexity leads to errors.
Suppliers should aim to standardize their EDI workflows wherever possible by:
- Using consistent mapping logic across partners
- Centralizing EDI management rather than handling it in silos
- Maintaining clear documentation for partner-specific requirements
This reduces variability, improves scalability, and ensures consistent performance across all customer relationships.
Turning EDI Execution Into a Competitive Advantage
Vendor scorecards are no longer just performance reports—they are part of a larger vendor management system, and they directly influence which suppliers retailers choose to grow with. As we’ve covered, your score is driven by execution: invoice accuracy, ASN timeliness, and data consistency. While many suppliers understand these metrics, fewer take the steps needed to consistently meet them.
That’s the opportunity.
By implementing proactive EDI practices—like pre-transmission validation, ERP-driven automation, and real-time visibility—you move from reacting to issues to preventing them altogether. The payoff goes beyond a higher score: fewer chargebacks, stronger retailer relationships, and more opportunities for growth.
