2. Select the Track inventory checkbox to enable entering information that PayPal uses to
track inventory for your item. Then, do one of the following:
– By Item – Select this radio button if you want to track inventory regardless of product
options selected by buyers.
Enter the quantity that you currently have in stock and an alert level. PayPal sends you
an alert by email when your inventory on hand falls to or below the alert level.
– By Option – Select this radio button if you want to track inventory by the product options
you specified during Step 7 of “Step 1 – Specifying Basic Features of Your Buy Now
Button” on page 40. If you set up product options with prices, the button creation tool
automatically selects this radio button.
For each option listed, enter a unique item ID, the quantity that you currently have in
stock, and an alert level. PayPal sends you an alert by email when your inventory on
hand for any option falls to or below its alert level.
Under the Can customers buy an item when it is sold out? heading, do one of the
following:
– Yes – Select this radio button to let buyers checkout and authorize their payments, even
when inventory tracking shows that your item would become oversold. Buyers are not
informed of oversold or out-of-stock situations nor that their items will be on back order
after they complete their transactions.
– No – Select this radio button to prevent buyers from checking out and authorizing their
payments when inventory tracking shows that your item would become oversold. In the
text box, enter the URL of a page on your website where you want PayPal to send buyers
of out of stock items. When PayPal detects an oversold situation, PayPal lets buyers
know that the item is out of stock.
If there are some items in stock, but not enough to fulfill a buyer’s request, PayPal
displays the amount currently available and adjusts the number in Quantity.
