One page per account, computed monthly: revenue and trend, share against norm, missing lines valued, contact recency against cadence, dormancy state, share of the rep's book, and pipeline with slip count. Three actions follow by rule; the rep's judgement is a dated box on top, never typed over the numbers.
Twenty written plans cover the twenty everyone knows. The fortieth account has a computed plan too.
Sell line B. Touch, overdue 26 days. Move the deal that slipped twice. Not "deepen the relationship".
One page per account, rebuilt each month from computed tables: revenue and trend against the same period last year, share against the norm by category, the missing lines with a value on each, contact recency against cadence, open issues and contract dates. The owner adds judgement and next steps.
An account at $610,000, down 18 percent, buys two of six categories, has one known contact and a contract ending in five months. The plan lists the three missing categories at $180,000, a second contact to find by a date, and a director visit.
Plans written from memory once a year. They describe the relationship the owner believes in, not the one in the ledger, and are not opened again.
