To do a storewide pre-sale on Shopee, you can follow these steps:

Create a pre-sale item:

Open the Shopee merchant backend and go to the "Item List".

Select the item you want to set as pre-sale to edit.

If the current status of the item is not pre-sale (No by default), change it to pre-sale (Yes).

Enter the expected delivery time of the item and make sure you enter the number of working days.

Finally, click the "Update" button to save the changes to your Shopee store.

Set pre-sale rules:

You can choose whether to allow buyers to place orders during the pre-sale period.

Set the start date and time and the end date and time of the pre-sale item.

Make sure you have met the eligibility requirements as a seller, such as becoming a Shopee certified seller.

Shipping schedule:

The shipping time of pre-sale products is usually completed within about 5 to 7 working days after the pre-sale ends.

Shopee will not limit the specific delivery time, but the actual delivery time may vary due to possible logistics or other factors.

After-sales service processing:

For pre-sale products, if a return or exchange request occurs, the Shopee platform will provide a solution based on the specific situation.

It should be noted that different markets (such as Shopee, Bukalapak, Tokopedia) may have different pre-sale setting processes and regulations. Therefore, you also need to set it up according to the specific guidelines of the target market.
