Use value carefully
Quote value can help put the scale of a set of estimates in context. It can also be overstated by expired pricing, duplicate options, changed scope, and quotes that cannot still be fulfilled. Define which version and counting unit you use.
Separate outcome from reason
A known competitor decision can have an unknown reason. A still-open estimate can have a clearly stated timing reason. Keep those dimensions separate before grouping totals.
Follow the actual outcome
Track a later sale, completed work, collected revenue, and contribution profit according to the shop’s accounting definitions. Keep operating costs visible. Do not label the face value of an unsold book as lost or recoverable revenue.
