Tacit work has no invoice line
I described a service I had shaped around one client's way of working and my partner heard a growth plan. The thing that would actually have to move is the part that has not once made it onto a quote.
capacity model
Meaning
A structured calculation of available labor hours restricts the volume of commitments an operator can sustain over a specific duration. By applying a capacity model, the founder divides specialized labor into standardized increments that can be scheduled and sold. It establishes a boundary between the hours required to run the business and the hours that can be billed directly to clients.
This allocation keeps the service delivery predictable.
Labor Allocation
Task distribution depends on distinguishing between standardized tasks and highly variable problem solving. When an operator relies on a capacity model, the work is grouped by complexity to ensure that routine activities do not consume the hours needed for custom work. The builder calculates the expected load of each commitment and compares it against the remaining availability in the weekly schedule.
If the tasks are too complex, the allocation fails and requires manual adjustments.
Delivery Limit
Overtime occurs when the commitments exceed the calculated boundary of labor. A capacity model operates as a ceiling on the promises made to buyers of the service. By setting this limit, the provider avoids the burnout that follows from trying to scale through unpaid overtime.
The limit acts as an early warning for the team.
Sustained Output
Long term productivity requires a reserve of attention that can absorb unexpected delays or system failures. In a typical week, some portion of the total available hours must remain open to handle these non routine tasks. Without this margin, the capacity model breaks down under the weight of ordinary delivery friction.
This reserve protects the team from exhaustion.
