Client Profitability Agent Skill

Client Profitability Analysis

Overview

Break down revenue and direct costs by client to determine which accounts are most and least profitable. Reveals hidden costs in high-maintenance clients and identifies your highest-value relationships.

Wilson Tools Used

• transaction_search — find all revenue transactions grouped by client/vendor name, and all expenses attributable to specific clients
• spending_summary — calculate overhead costs to allocate across clients

Workflow

• Ask for the analysis period and list of active clients (or detect from transaction data).
• Use transaction_search to find all incoming payments, grouped by client name or reference.
• Use transaction_search to find all expenses directly tied to each client (contractor costs, materials, software licenses specific to a project).
• Use spending_summary to get total overhead (rent, utilities, general subscriptions).
• Allocate overhead proportionally by revenue share: Client Overhead = Total Overhead * (Client Revenue / Total Revenue).
• Calculate per-client profitability:

• Rank clients by profit margin, not just revenue.
• Flag clients with margins below 20% as candidates for price renegotiation or scope reduction.

Without Wilson

• Export bank transactions as CSV for the analysis period.
• In a spreadsheet, add a "Client" column. Tag each income and expense row with the client it relates to. Tag overhead expenses as "General."
• Create a pivot table: Rows = Client, Values = Sum of Income, Sum of Direct Expenses.
• For overhead allocation, calculate each client's revenue share: =ClientRevenue/TotalRevenue.
• Client Overhead = =RevenueShare * TotalOverhead.
• Client Profit = =ClientRevenue - DirectCosts - AllocatedOverhead.
• Client Margin = =ClientProfit/ClientRevenue*100.
• Sort by margin descending. If you use time tracking (Toggl, Harvest, Clockify), export hours per client and calculate effective hourly rate: =ClientProfit/HoursWorked.

Important Notes

• The hardest part is attributing expenses to specific clients. If you cannot tie an expense to a client, it goes into overhead.
• Time is a hidden cost. A client paying $10,000/month but consuming 80% of your time is less profitable than it appears. Consider tracking hours per client alongside dollars.
• Overhead allocation by revenue share is simple but imperfect. A client generating 50% of revenue but only 20% of support tickets is being over-allocated overhead.
• Use this analysis to decide where to invest sales effort, which clients to fire, and where to raise prices.
