ANECDOTE

The Growth Trap Cycle

Many agencies grow rapidly by hiring more staff to manage increased work but see profitability drop.
Founders often discover that despite more revenue and clients, they take home less money than when smaller.

ADVICE

Calculate Agency Gross Income

Separate pass-through expenses from revenue to calculate agency gross income (AGI).
Focus profitability analysis on AGI, not just top line revenue, for realistic business insights.

ADVICE

Maintain Delivery Margin Under 50%

Keep delivery costs under 50% of AGI to maintain a strong delivery margin.
Allocating payroll and software costs correctly between delivery and overhead is crucial.

3:05 – 3:18 – 80/20 Profitability Focus: The goal is to give agencies 20% of the knowledge that provides 80% of the insight needed to take control of profitability, regardless of market conditions.
4:28 – 6:27 – The Growth Trap Cycle: Agencies often get stuck in a cycle of hiring during growth, losing profitability, scaling again, and repeatedly encountering the same financial challenges at larger scales.
6:42 – 7:01 – Identifying the Real Problem: Founders are urged to identify whether their agency's issue is inefficient delivery (indigestion) or lack of revenue (starvation) to avoid insolvency.
9:01 – 10:06 – Financial Metrics Foundation: Understanding core financial metrics—especially agency gross income (AGI)—is essential to making better business decisions beyond tax reporting.
14:24 – 18:05 – Delivery Margin as the Core Metric: Agencies should aim for delivery costs to stay under 50% of AGI, enabling better spending on overhead and stronger profitability.
21:44 – 26:44 – Lever 1: Average Cost Per Hour: Lowering the average cost of labor through delegation and improved processes helps reduce delivery costs and increase profitability.
28:03 – 31:55 – Lever 2: Average Billable Rate (ABR): Maximizing revenue per hour of delivery time, regardless of billing model, improves margins—either by pricing higher or working more efficiently.
34:17 – 38:24 – Lever 3: Utilization Rate: Utilization measures how much team capacity is spent on client work; improving it by selling more work or adjusting staff size directly affects profitability.
42:01 – 44:45 – Utilization Benchmarks: Weekly and annual utilization targets vary by role; producers should aim for 75%+ weekly, and teams should average 50–65% annually including all roles.
45:27 – 49:26 – Impact of Levers on Profit: A case study illustrates how modest gains in utilization and ABR can shift profit margins from 10% to 40%, increasing valuation by up to 500% without hiring or cutting overhead.
