An abandoned shopping cart should not mean a lost sale. With effective marketing you can convert a majority of your abandoned carts into sales. The shopper has already told you what products they're interested in. You have a perfect opportunity to provide that shopper with personalized marketing to help close the sale.
When a shopper abandons your cart, you should immediately provide them with personalized information to convince them to complete the sale. Send them an email with additional information about the product they abandoned, and with a coupon for that product that is valid for a limited time. Follow-up with a drip marketing campaign(opens in new tab) that sends a sequence of emails until the shopper completes the purchase, with additional information pertinent to the product and reminders of the limited time discounts available But make sure the follow-up emails do not drive the shopper away, and they end as soon as the shopper completes the purchase.
To find out which shoppers abandoned your cart and what they abandoned, just run a Customer search inside NetSuite. The criteria for the search should be customers that have a Shopping Cart : Amount greater than $0. You can further segment customers by which Items they abandoned – just use that same Customer search and also use a criteria of Shopping Cart(opens in new tab) : Items in Cart.
