1. Overview

Order status, recipient details, tracking numbers, activity history, return and exchange requests, refund amounts and imported orders are saved in the browser. They stay after a refresh or a return visit.

Connected at rollout: automatic links to the store and courier (automatic order collection, tracking number sending, delivery tracking), actual refund payments, customer text and email notifications, login and staff permissions, and server storage shared across devices.

2. Challenges

1. Staff should not have to hunt for delayed orders.

Orders not shipped two days after payment, or orders missing an address, get buried in the list. Problem orders should gather at the top with the reason, so none are missed.

2. Stop shipping mistakes at the input step.

If a tracking number has the wrong number of digits or belongs to another order, the customer cannot track the delivery. Accidentally canceling an order that has already shipped must also be blocked.

3. Stop working out return refunds on a calculator every time.

For a change of mind, the return shipping fee is deducted. If a free-shipping order falls below the threshold after the return, the original shipping fee is deducted too. For defects, nothing is deducted. These rules should be calculated on screen and recalculated based on the inspection result.

3. Structure

You move between screens with colored index tabs on the side of a notebook (orders, returns, exchanges, import orders). Orders and return requests open in a panel that slides in over the list, and you move through the steps inside that one panel. The number on each tab is the count of priority orders and returns waiting to be processed.

4. Key Features

Priority Items — Late Shipments, Missing Details, Amount Checks

Orders still not shipped two days after payment, orders with no address or an invalid phone format, orders where item total and payment amount do not match, and orders with a return request gather at the top with the reason. Once the problem is fixed, the order drops off the list right away.

Tracking Number Entry and Shipping

In the order panel, move through Preparing → Enter tracking number and ship → In transit → Delivered. Tracking numbers accept only 10–13 digits. Numbers already used on another order, and orders missing recipient details, cannot be shipped. Orders can be canceled only before shipping, and a reason must be selected.

Return & Exchange Intake and Refund Calculation

For a delivered order, choose the items and quantity to register a return. The expected refund updates as you choose. For a change of mind, a ₩3,000 (Korean won) return shipping fee is deducted. If a free-shipping order falls below ₩30,000 after the return, the original ₩3,000 shipping fee is deducted too. Defects and wrong items have no deduction. For exchanges due to a change of mind, round-trip shipping is shown as paid by the customer.

Return Processing — Pickup → Inspection → Refund

Entering the pickup tracking number moves the return to "picking up," and arrival moves it to inspection. If inspection finds no defect, the reason changes to change of mind and shipping fees are recalculated. An exchange is finished only when the replacement's tracking number is entered. Rejecting requires a reason, and every step is recorded on both the return and the original order.

• Order File ImportUpload a CSV downloaded from the store admin, and rows with the same order number are grouped into one order for preview. Existing orders are skipped, unknown product codes are set aside as errors, and missing addresses or amount mismatches are added with a "to check" flag. Korean files saved from Excel (EUC-KR) are also read without broken characters.
• Order List — Status Tabs, Search, Bulk ActionsEach order is a card, and the color of the card header shows its status (paid, preparing, in transit, delivered). Orders that need checking get a red shadow. Filter with status tabs and search by order number, customer or product, and move several paid orders to "preparing" at once. Visible orders can be downloaded as a CSV with one row per item. The CSV is saved so Korean text does not break in Excel.
• Return & Exchange ListFilter by in progress, received, picking up, inspection, completed or rejected, and see type, reason, item and expected refund for each request in one row. All requests can be downloaded as a CSV that includes shipping deductions and refund amounts.
