How do I set the quantity of a product?
When you are Adding a product, click advanced settings.
To set a quantity to an already existing payment link/product:
Find the link in your Dashboard under 'Product and Store', click on the three dots and then on Edit product.
Go to Advanced Settings and Enter the quantity in the ‘Limit Quantity to’ field. For example: If you have 5 pieces of a product, enter ‘5’ in this field. When 5 orders are placed for the product, it’ll automatically go out of stock.
Click on Update Settings.
