For e-Commerce Sites, selling to the customer is the biggest target, but after-sales services are essential for the continuity of the customer. In the computer environment, together with cutting the invoice, transferring the current information in the commercial program in a correct format, failure to register during the stock records, and the increase in sales, start to pose a serious problem

Since many e-commerce companies cannot grow their daily sales and invoicing processes, they send their products to their customers late. When there are requests for return or replacement of products, there are serious problems arising from the incompatibility of the e-commerce website with the accounting program stock codes. The sale of a non-product is a situation that occurs frequently, but creating major problems. The customer can object to the return of the product he ordered, create complaints in different media thinking that he can solve the problem by discussing it with different people, and make the situation disrupt the functioning of the virtual store.

With commercial software integrations, both internal processing is automated and errors are minimized by automation, as a result, employees' motivation arises and their performance increases. As a result of all this, there is a significant reduction in costs as more work can be done with less personnel.

There are 2 common integration models available. In the first model, the virtual store is taken to the center and commercial software is used to track the accounting processes. In the second model, the Commercial software is in the center. Projects that do not have a stock standard that sells non-commodities by taking XML from different platforms prefer the first model. When products are sold in this model, during the transfer of orders, they are checked whether they are in the commercial software, otherwise they are selected if they are created. Stock amounts from commercial software are not transferred to the site. The amount of stock is entered on the site. Therefore, while tens of thousands of products are sold on the site, the commercial software only contains products that have been sold since the past.
