QuoteCloud provides the ability to add & edit spreadsheets in your sales quote.
Spreadsheets are very useful if you want to create a table of data that performs calculations. A common example of using a spreadsheet in sales quotes, is a "return on investment calculator", where you need to demonstrate the return on investment to a customer when buying your products. e.g. in the solar industry you might have a spreadsheet to calculate cost savings when solar panels are installed in a home.
