The decision boundary at the outset
The practical reading of agency retainer profitability begins here: calculate monthly agency retainer contribution after delivery labor, freelance, software, and account-support cost. Use it to answer a narrow question about client economics records, not to automate policy.
When agency retainer profitability enters the decision file, no benchmark enters automatically, so every target or comparison needs a named source.
For agency retainer profitability, begin by agreeing how Monthly client retainer and Account management cost enter the client engagement review. That discussion often prevents a technically correct result from answering the wrong management question.
Establish the source trail
Engagement economics file: Date the extraction supporting Monthly client retainer. Separate target monthly client retainer from observed evidence. Net Monthly client retainer with Delivery hours only when displayed.
Engagement economics file: Check Delivery hours for cancellations or reversals. Preserve unrounded delivery hours evidence. Retain adjusted Delivery hours when Loaded labor cost per hour is adjusted.
Engagement economics file: Keep Loaded labor cost per hour on the stated unit basis. Preserve unrounded loaded labor cost per hour evidence. Flag conversions before combining Loaded labor cost per hour with Freelance and production cost.
The accountable owner of agency retainer profitability should remember that engagement economics file: Document every exclusion from Freelance and production cost. Assign an owner to freelance and production cost. Document whether Freelance and production cost leads or follows Client-specific software cost.
Engagement economics file: Store an unadjusted Client-specific software cost value. Retain the source column for client-specific software cost. Keep evidence for Client-specific software cost distinct from Account management cost.
Engagement economics file: Name the person approving Account management cost. State the population behind account management cost. Label the assumption status of Account management cost and Monthly client retainer.
