The Client
A high-volume home furnishing manufacturer supplying major digital marketplaces.
The client is a leading home décor and rug retailer operating through the Amazon Vendor Central platform across multiple North American marketplaces. As a first-party (1P) supplier to Amazon, the company fulfills bulk inventory orders directly to Amazon’s fulfillment centers, supporting their catalog of home design products. Fulfilling orders at this scale requires managing a continuous stream of purchase orders (POs), shipping notices, and compliance checks.
Selling through Amazon Vendor Central requires strict adherence to operational standards. Amazon enforces tight delivery windows and exact packaging codes. Any mismatch between the initial Purchase Order, the physical shipment, and the Advanced Shipping Notice (ASN) triggers immediate financial penalties, known as chargebacks. These chargebacks, combined with shipping delays, can erode retail margins and impact a vendor's performance scorecard.
With transaction volumes increasing across multiple distributor accounts, the client's internal operations team was struggling to keep up with the validation steps needed to ensure shipping compliance, resulting in processing backlogs and increased compliance risks.
The Challenge
The operational challenge of Amazon Vendor compliance.
The client faced significant operational bottlenecks in managing high-volume Purchase Orders across multiple Amazon Vendor accounts. Each week, Amazon issued large bulk purchase requests that required rapid verification against internal inventory levels, SKU-to-ASIN mappings, and warehouse shipping schedules.
Before inventory could leave the warehouse, the client had to submit an Advanced Shipping Notice (ASN) containing details on container configurations, tracking numbers, and Serial Shipping Container Codes (SSCC).
The client's manual review process was slow and prone to errors. This resulted in delayed ASN submissions, carrier scheduling conflicts, and an increased risk of Amazon compliance chargebacks that impacted operational efficiency.
High-volume POs across multiple Amazon accounts strained the client's internal processing capacity.
Complex validation checks were required to verify SKU and ASIN details before shipping.
Manual ASN submission processes increased the risk of formatting errors and Amazon penalties.
What our audit found
Manual checkpoints causing supply chain delays.
We began our engagement by auditing the client's order processing and shipping workflows. We tracked the lifecycle of a purchase order from initial receipt in Amazon Vendor Central to final delivery confirmation at the fulfillment center.
The diagnostic revealed that the primary bottleneck was the manual reconciliation of product codes. Internal SKU numbers and Amazon ASINs were mapped using static spreadsheets, which were frequently outdated. This led to discrepancies in shipment quantities and SSCC labels.
Additionally, because the team was processing POs manually, they had limited time to perform shipping checks before ASN submission, leading to errors in tracking numbers and package counts that triggered Amazon compliance alerts.
Outdated mapping files led to SKU-to-ASIN mismatch errors during order validation.
Manual checking of shipment records delayed the generation of Advanced Shipping Notices.
Lack of centralized tracking made it difficult to monitor order statuses across different warehouses.
The Solution
How we turned it around.
SKU & ASIN Data Reconciliation
We designed a structured validation workflow to automate SKU and ASIN verification. We built a master mapping database that cross-referenced internal inventory codes with Amazon's standard identifiers, introducing automatic checks to flag mismatches.
Our team performed regular audits of the product database, verifying that new listings and bundle configurations were mapped correctly. This data reconciliation process ensured that incoming purchase orders were matched with the correct warehouse inventory before fulfillment began.
What we shipped
- Built a master SKU-to-ASIN mapping database to reduce verification errors.
- Introduced automated data reconciliation steps to check product codes.
- Standardized product details across multiple North American Vendor accounts.
Purchase Order Management & Validation
We established a dedicated support team to manage the client's purchase order queue. Our team monitored Vendor Central dashboards around the clock, reviewing and validating unconfirmed POs as they were issued.
We verified order quantities against real-time warehouse stock levels, flagging items that required adjustment. By speeding up the PO validation process, we helped the client confirm orders within Amazon's required windows, preventing order cancellations.
What we shipped
- Monitored purchase order queues to ensure timely order confirmation.
- Verified order quantities against warehouse inventory logs.
- Resolved order discrepancies before shipments were finalized.
ASN Submission Management
We developed a step-by-step validation process for Advanced Shipping Notices (ASNs). Before submitting ASNs to Amazon Vendor Central, our team cross-checked shipping quantities, SSCC codes, and carrier tracking details against physical warehouse pick logs.
This process ensured that the digital notice matched the physical shipment. By verifying container codes and carrier details, we eliminated the common errors that trigger Amazon's receiving chargebacks.
What we shipped
- Verified shipping details and tracking numbers before ASN submission.
- Reconciled SSCC codes to ensure compliance with Amazon labeling guidelines.
- Reduced the errors that cause automated receiving penalties at Amazon warehouses.
Compliance & Tracking Workflows
We implemented standardized trackers to monitor the status of every purchase order and shipment. Using shared files and Microsoft Teams integrations, we built a communication loop between warehouse managers, logistics partners, and the compliance team.
This tracking system gave the client real-time visibility into shipping deadlines, pending ASN submissions, and potential carrier delays, allowing the team to address issues proactively.
What we shipped
- Set up shared tracking tools to monitor the lifecycle of shipments.
- Improved coordination between logistics teams and back-office support.
- Provided real-time visibility into shipping compliance deadlines.
The Numbers
Outcomes we can talk about.
The implementation of the standardized BPO support team improved the client's Amazon Vendor Central operations. By replacing manual checks with structured validation workflows, the company achieved faster reporting and submission turnaround times for both purchase orders and shipping notices.
The accuracy of PO and ASN processing improved, reducing mismatches between internal inventory records and Amazon's receiving logs. This directly enhanced Amazon Vendor Central compliance, reducing the frequency of compliance penalties.
By establishing reliable operational support across multiple marketplaces, the home décor retailer stabilized its logistics pipeline. This allowed the company to scale its Amazon sales volume without experiencing a corresponding increase in operational backlogs or customer service friction.

What We Built
What's Next
Implementing EDI integration and automated inventory sync.
With the back-office operations stabilized, the next phase will focus on automating data exchanges through Electronic Data Interchange (EDI) systems. We will work with the client's IT team to link their ERP software directly to Amazon Vendor Central, allowing for automated PO ingestion and inventory updates.
We will also develop predictive inventory alert dashboards. By analyzing historical Amazon purchase patterns, the system will alert the production team to potential demand spikes weeks in advance, helping to prevent stockouts on popular rug and décor items.
Frequently Asked Questions
About This Project
The questions teams usually ask when they want to run a similar engagement.
A SKU (Stock Keeping Unit) is an internal code used by a retailer to manage inventory. An ASIN (Amazon Standard Identification Number) is a unique ten-character block used by Amazon to identify products within its catalog. Accurate mapping between the two is vital for e-commerce fulfillment.
