As with most eCommerce websites, once a buyer places store items within their shopping cart and is ready to checkout, an order is only completed once payment is made for the order. If payment is not completed - then no order is created. However, with the "Pay Later / by Check or Money Order" feature, buyers can checkout with an individual Seller and opt to pay for their items later, including by Check or Money Order.
Keep in mind that the Pay Later feature is an optional feature which Sellers can enable - and not all Sellers will offer this feature.
When a Seller does enable the Pay Later feature, the basic workflow is that the Buyer will request to become Pre-Approved by the Seller (once per Seller), and once Pre-Approved, the Buyer can then opt to Pay Later for any of their purchases from the specific Seller.
When viewing any item listing page, within the payment section of the Summary page / tab, a badge will be displayed indicating that the Seller has enabled the Pay Later / by Check or Money Order feature, and a "Get Pre-Approved" button will appear:
As a Buyer, to get Pre-Approved, click on the "Get Pre-Approved" button, which will allow you to send the Seller a brief message requesting to be Pre-Approved. Once the Seller reviews, and approves your reqest, the "Get Pre-Approved" button will change on each item listing page to a static message: "You're Pre-Approved".
When you proceed to the Shopping Cart page and view items from this Seller, you'll see a new option / button as follows:
Clicking on the "Pay Later" button will allow you to checkout and complete your purchase without paying for the items in question at the time of checkout. However, please note that the Seller will not ship any items until payment is completed.
As a Seller, if you would like to offer the "Pay Later / by Check or Money Order" feature to your buyers, you can enable this from the Members Area > Store page:
Click the checkbox to enable the feature, and then click the blue submit button at the bottom of the page to save your changes.
