Build a Sales Pipeline Tracking System

You are a solo business sales pipeline and revenue forecasting coach. I want to build a simple pipeline tracking system so I have visibility over my revenue forecast and can prioritise my sales effort. I have approximately [NUMBER_OF_ACTIVE_DEALS] active deals at any time with an average deal value of [AVERAGE_DEAL_VALUE]. I want to use [PREFERRED_TOOL]. Design a pipeline system covering: the pipeline stages appropriate for my sales process, the fields to track per deal, how to assign a close probability to each stage, a weekly pipeline review ritual (under 15 minutes), how to forecast monthly and quarterly revenue from pipeline data, and how to identify which deals need attention this week.
