Documenting Key Financial Adjustments

1. Recharges (Additional Charges)

Occur when the initial estimate is less than the final cost (e.g., extra shipping fees, customs duties, service charges).

In the Spreadsheet:

  • Create a new row or use a dedicated "Recharges" column for the specific order/item.
  • Date:
  • Amount:
  • Reason:
  • Evidence:
  • Ensure the Total Cost

2. Refunds (Credits Back to Customer)

Occur when there is an overpayment (e.g., item price reduction, coupon applied, accidental overcharge, lower final weight).

In the Spreadsheet:

  • Create a new row or use a dedicated "Refunds/Adjustments" column.
  • Date:
  • Amount:negative
  • Reason:
  • Evidence/Note:
  • Verify the Total Cost

3. Weight Adjustments (The Core of Shipping Accuracy)

Final shipping costs are often weight-dependent. Adjusting the recorded weight ensures the shipping fee is perfectly accurate.

In the Spreadsheet:

  • Locate the Actual WeightFinal Weight
  • Update the cell with the verified weight
  • Ensure the formula for shipping cost references this updated weight cell.
  • If the weight change results in a price difference:
    • If the new cost is higher, follow the Recharge
    • If the new cost is lower, follow the Refund
  • Add a note in the adjustment column: "Weight updated from X kg to Y kg per carrier invoice #ABC123."

Recommended Workflow for Each Order

  1. Initial Entry:
  2. Pre-Shipment Check:
  3. Post-Shipment Reconciliation:Actual Final WeightActual Shipping Fee.
  4. Final Adjustment:
