No, it is your responsibility to keep track of your inventory. Future releases may accommodate this feature. If you run out, or discontinue the sale of a product, it should be disabled in our system and links to it should be removed from your site. You may be able to find a 3rd Party Shopping Cart that can meet your needs.

A chargeback is a forced refund from a bank/credit card provider. It occurs when an account holder decides to formally dispute a charge on their account. Chargebacks occur on less than 1% of all 2Checkout.com transactions. According to credit card association rules, Internet merchants must accept chargebacks as part of the normal risk of doing business on the Internet.

The amount of disputes you experience will vary according to the type of products you sell. Products that will experience a higher degree of chargebacks are intangible and products that appeal to children, teenagers, and single adults. Products that will experience a lower amount of chargebacks are tangible products and products purchased primarily by professionals and families.

• Be sure that customers are completely familiar with your delivery process. If you are shipping expensive items, use a package service that provides proof of delivery. There will always be some customers out there who falsely claim that a package was not received (and occasionally there will be packages that truly are lost or stolen). Since you bear the responsibility for those losses, you should take care not to put large amounts of money at risk.
• Respond to 2Checkout.com’s requests for information promptly.
• Make customers aware that 2Checkout.com is your authorized reseller. A link to our ticket system or a list of the phone number for our customer care center can be posted on your website.
• Thoroughly describe your offering, show photos, and disclose any important limitations. Ensuring the customer’s expectations match what arrives in the mail will save you and the customer time, money and aggravation.
• Respond to customer requests for assistance promptly. If an issue can not be resolved to the customer’s satisfaction offer them a partial or full refund.
• Manually review all incoming orders for fraud. If you have any suspicions about an order, please contact our Fraud Department at fraud@2co.com for assistance.
• To ensure that they wanted to place multiple orders, contact all customers placing more than one order within a short amount of time.
• If you are selling a product/service that entails multiple billings, make sure that the customer is fully aware of the future billings and your cancellation policy.

The e-mail confirmation is not optional or customizable. You can however add additional information to the email by passing it in with the merchant_order_id parameter (50 characters max). You can also send your own e-mail in addition to ours, and/or pass the buyer back to an information page on your site after the purchase.
