Business Transactions

Entry: Left Navigation → Account & Billing → Business Transactions

Business transactions record the billing details generated by various business operations in the system. The system clearly categorizes transactions by business scenario, and you can quickly switch between views using the top tabs:

• All: View billing transactions for all business operations.
• Storage Fee: View storage fee details incurred from inventory storage.
• Inbound: View value-added service fees related to inbound operations (such as labeling fees, unloading fees, photography services, etc.).
• Outbound: View fees related to outbound operations (such as transfer shipping fees, packing operation fees, etc.).

1. Core Fields in Transaction List

The system list provides comprehensive billing dimensions to help you verify each transaction:

• Transaction No.: A unique number automatically generated by the system for each billing record.
• Business Document No.: The associated actual business document number (such as inbound receipt number, outbound order number, etc.; storage fee transactions typically have no corresponding business document number).
• Business Type/Business Category: Identifies the business that generated the fee (such as "Outbound - Order Outbound", "Inbound - Warehouse Value-Added Services").
• Billing Item: The specific charge item (for example: storage fee, single item shipping fee, product labeling fee, etc.).
• Billing Quantity/Unit Price/Amount: Records the calculation factors for this charge and the final deducted amount.
• Source: Indicates how the fee was generated (such as system for automatic system billing, manual entry).
• Status/Billing Status: Identifies whether this transaction is currently valid and whether it has been settled and billed.
• Creation Date: The time when the fee was generated/recorded.

Tip: At the bottom of the list, there is a "Total" row where the system automatically summarizes the unit price and total amount for the current page or filter conditions, making it easy for you to quickly reconcile accounts.

2. Filtering and Operations

• Multi-dimensional Filtering: Supports precise queries by Billing Period, Transaction No., Source, Status, and Billing Status.
• Export Report: Click the [Export] button in the upper left corner to export transaction data locally for further financial analysis.

3. Fee Details and Storage Fee Traceback

In the transaction list, clicking on a specific transaction record will open a "Fee Details" window, allowing you to dig into the underlying basis for each charge. For "Storage Fee" transactions in particular, the system provides detailed data traceability capabilities:

• Basic and Detailed Information: Clearly displays the basic record of this transaction (Transaction No., Creation Date) and core billing data (total billing quantity/volume, unit price, final deducted amount, billing status, etc.).
• Storage Fee Traceback: Since storage fees are dynamically calculated daily based on inventory snapshots and lot age, the details page provides a "Storage Fee Traceback" detail table at the bottom, breaking down the total storage fee:
  • Precise Traceability to Inbound Lots: The detail table lists all underlying inventory details involved in the storage fee calculation.
  • Core Field Display: Includes product SKU/SSKU, Source Document No. (corresponding inbound receipt for tracing which batch of goods), Inbound Time, Lot Age (days), Quantity in stock, Dimensions (length, width, height), single item volume, Total Volume used to calculate this fee, and applicable Unit Price.
  • Quick Search and Investigation: Supports filtering details through the search box (enter SKU/SSKU/Product Name/Source Document No.). If storage fees suddenly increase on a certain day, you can use this feature to quickly identify which high-age, large-volume products drove up the costs, enabling timely outbound or disposal strategies.

Storage Fee Billing Instructions (Tiered Pricing by Lot Age)

To improve warehouse turnover rate, the system uses a tiered pricing model based on inventory lot age for storage fees. The longer goods are stored in the warehouse, the higher the storage cost.

1. Core Billing Rules

• Billing Unit: m³ (cubic meters)
• Billing Cycle: Billed daily. The system automatically executes billing tasks at 00:10 every day, calculating and generating storage fee transactions for the previous day (system source displays as system, business category as Storage Fee).
• Lot Age Definition: Refers to the actual number of days a specific inventory lot has been stored from the date of inbound completion to the current date.
• Independent Billing by Lot: If the same SKU has multiple different arrival lots, each lot will independently calculate lot age and volume, and the system calculates storage fees for each lot separately before summarizing.
• FIFO (First In, First Out) Outbound: When shipping orders and deducting inventory, the system defaults to the first-in, first-out principle, prioritizing the deduction of inventory lots with the longest age and earliest arrival. Through this approach, the system automatically helps you accelerate old inventory turnover and minimize high-tier storage costs caused by long-term slow-moving stock.

2. Storage Fee Tiered Pricing Standard

The warehouse tiered pricing standard is as follows (excluding tax):

Lot Age Range	Default Storage Unit Price
0 ~ 30 days	55 JPY / m³ / day
31 ~ 90 days	90 JPY / m³ / day
91 ~ 180 days	135 JPY / m³ / day
181 ~ 365 days	180 JPY / m³ / day
> 365 days	270 JPY / m³ / day

3. Calculation Formula and Example

• Calculation Formula: Daily Storage Fee = Inventory Volume (m³) × Tiered Unit Price for Lot Age
• Billing Example: A batch contains 100 items, with each item having a volume of 0.02 m³ (Total Volume = 100 × 0.02 = 2 m³). The current lot age is 45 days, matching a tiered unit price of 120 JPY. The daily storage fee for this batch is: 2 m³ × 120 JPY = 240 JPY / day.
