XML Files are one of the most common formats eCommerce shopping carts support. In Integration Manager, XML Files are treated like any other shopping cart. Extensiv Integration Manager provides terrific tool for online merchants and fulfillment centers to easily load common XML formats without needing expensive custom programming. If you find that your store grows quickly, you will end up bogged down with shipping and managing all of those orders every day. You will find that you need a more powerful shipping system, or even need to hire a 3rd party fulfillment center so that you can concentrate on what all small business owners need to – marketing and selling your products. If this is the case, then you will need a way to integrate your XML files with another piece of software. You will also need to sync your inventory and order tracking information so that your store is constantly updated.
