Every deal in flight, by stage and by value. The list shows Name, Account, Stage, Amount, Probability, Close date and Owner; switch to the kanban to drag deals between stages.
New opportunity — the Deal (Amount and its Currency code, Expected revenue, Probability, Close date, Quantity), Relationships (Account, Campaign, Owner, Lead source, Type) and Execution (Next step, Forecast category, Competitors, Order number, Delivery status, Description).
The opportunity page has tabs Overview, Contact roles (who at the account plays which part), Team (the opportunity team and their roles), Splits (how credit for the deal is shared), Activities, Files and History. Stages, their probabilities and whether they are won or lost come from Settings → CRM → Sales configuration → Opportunity stages.
Quotes (on the opportunity's Overview) lists the estimates made for the deal, with their total and whether they are open, accepted or invoiced. Create quote opens a new estimate with the account's customer, the deal's currency and the deal's name as its reference; the account must be linked to a customer first (section 18.3). When an estimate made for a deal is marked approved, you are offered to close the deal — won, at the estimate's total.
