Review of EVERY Amazon Reimbursement Software - The best way to Request Reimbursement - FBA Tools

1. Check Product Size and Weight Data

Getting your product measurements right is essential for filing successful FBA reimbursement claims. Even small mistakes can lead to misclassification, which often means higher fees. Ensuring accuracy here can save you money and make the claims process smoother.

Start by using precise tools like digital calipers (with 0.01-inch precision) and calibrated postal scales (accurate to 0.1 ounces). Measure and record both the product and its packaging dimensions, as these together determine the size tier Amazon assigns.

Here’s a recommended schedule for keeping your data accurate:

  • Weekly checks for high-volume or newly listed products

  • Monthly audits for your entire product catalog

  • Immediate reviews after Amazon policy updates

  • Seasonal checks before busy shopping periods

If you spot discrepancies, take photos showing your measurement tools in action. Why? Even a single misclassified product can add $1.80–$2.50 in extra fees per unit.

Key measurements to track (in inches and pounds) include:

  • Product length, width, and height

  • Packaging dimensions

  • Total weight, including packaging

  • Product volume

  • Unit count for multi-packs

If Amazon reclassifies one of your products, here’s what to do:

  1. Measure the product again.

  2. Take photos to document the correct dimensions.

  3. Submit the evidence to Amazon Support.

  4. Keep a record of the case number.

  5. Watch your account for any fee adjustments.

For added efficiency, automated tools can help. These systems compare your measurements with Amazon’s data and flag any discrepancies. If you want to simplify this process even further, services like Refunzo’s automated reconciliation can handle it for you, ensuring your measurements and account data stay accurate.

2. Record Detailed Shipping Information

Keeping precise shipping records is essential to avoid mismatches between what you send and what’s received. This careful documentation is the backbone of smooth claim submissions if issues arise.

Here’s what you should track:

  • Box-level inventory lists: Include quantities and SKUs for each box.

  • Condition verification: Take photos of items to document their condition and any visible damage.

Verification Steps

  • Pre-shipment check: Double-check item quantities and ensure packaging is secure.

  • Create a shipping manifest: List all items with counts, SKUs, and box assignments.

  • Store records digitally: Use date-stamped files for easy retrieval.

  • Save receipt confirmations: Keep Amazon’s receiving confirmation emails and reports as proof.

To further organize your shipping process, maintaining a structured shipping log can make a big difference. Here’s an example of what to include:

Shipping Data Point

Details

Shipment ID

Amazon’s assigned shipment identifier

Date Shipped

Shipment date (MM/DD/YYYY)

Item Count
