An online marketplace system may allow sellers to create listings for items to sell. A seller may create a listing using an application installed on the seller's mobile device. The application may be configured so that a seller can very quickly provide information regarding an item, and therefore create a listing within minimal time investment. The application monitors data connectivity and detects connectivity problems that may create delays in providing item information to the online marketplace system. When there are problems with connectivity, the application caches the item information so that the user of the application does not perceive any latencies. When data connectivity improves, the application sends the cached item information to the online marketplace system for creation of the listing.
