What is sales data? What are its functions?

  Sales data is usually statistics/ information about the performance of your sales team and key trends around your pipeline/ current customers.

  The statistics might be how many leads have closed, time to close, stages of the sales cycle where deals are stuck. This data helps with forecasting and also understanding areas for improvement e.g. Deals are getting stuck after the proposal has been submitted- which may indicate the business cases don't have a strong enough call to action.

  Information or trends is more focused on key verticals, average customer size, lead source, the quality of leads from specific sources. This helps you to understand your ideal customer and where you should focus resources to get the best return on investment.
