Agency glossary
What do common agency-operations and profitability terms mean?
Plain-English definitions of the agency-operations and profitability terms we use across AgencyFlo.
A
- Account-management overhead
- Non-billable time spent running the client relationship: status updates, reporting, internal coordination and admin.
- Account-management overhead routinely consumes 10-20% of a senior's week and rarely appears on a timesheet honestly. It is one of the biggest gaps between booked utilisation and real billable output.
- Agency operating system
- A single platform that runs an agency's whole workflow (projects, time, CRM, proposals, contracts and invoicing) as one connected loop.
- Rather than wiring together separate tools, an agency OS keeps everything on one data model, so a paid invoice updates profitability instantly with no integrations to maintain.
- AI-native
- Software built with AI as part of its core, rather than bolted on as a separate assistant afterwards.
- In an AI-native operating system, the AI can see the whole loop (projects, time and money) so it can draft documents and flag margin risk in context instead of working from one isolated module.
B
- Billable rate
- The hourly rate an agency charges a client for a person's time.
- Billable rate is the price side of the equation; compared against internal cost rate, it determines the margin on time-based work.
- Blended rate
- A single average hourly rate charged across a mixed team instead of a different rate per role.
- Blended rates simplify quoting but can hide where margin is actually made or lost, which is why per-project profitability matters.
C
- Capacity planning
- Forecasting how much work a team can take on, based on available hours versus committed work.
- Good capacity planning prevents both over-servicing (which erodes margin) and idle time (which wastes payroll).
- Capacity-vs-sales constraint
- Whether an agency's growth ceiling is the work it can deliver (capacity-constrained) or the work it can sell (sales-constrained).
- Diagnosing this correctly changes where you invest next. A capacity-constrained agency that hires more salespeople just makes the bottleneck worse; a sales-constrained one that hires delivery staff burns cash on idle headcount.
- Closed-loop system
- A workflow where proposal → contract → project → time → invoice → paid → P&L all run as one connected sequence with no manual re-entry.
- Because each step feeds the next automatically, there are no seams where data drifts and nothing has to be reconciled by hand.
D
- Deliverable margin
- The margin made on a single deliverable (a campaign, a website, a brand system), independent of overall project margin.
- Project margin can hide loss-making deliverables when other parts of the scope subsidise them. Looking at deliverable margin separately tells you where the studio is genuinely winning, and which deliverables you should stop scoping at the current price.
E
- Effective hourly rate
- Total revenue from a project divided by the total hours actually spent on it.
- For fixed-fee work, the effective hourly rate reveals true profitability. A project can win the pitch on price and still lose money once the hours are counted.
G
- Gross margin (agency)
- Revenue minus the direct cost of delivery (mostly people's time), shown as a percentage of revenue.
- Agency gross margins on client work are often above 50%; net margin is lower once overhead is included.
- Gross retention
- The percentage of recurring revenue retained over a period, before any expansion from upsells or growth.
- Gross retention measures pure churn: how much of last year's recurring revenue is still there this year. For retainer-led agencies it is the leading indicator of long-term health; net retention (which adds expansion) can mask underlying churn if a few accounts grow fast.
N
- Net margin
- What's left of revenue after all costs (delivery and overhead) are subtracted.
- Healthy agencies typically target a 20-30% net margin. Seeing it in real time, not at month-end, is what lets you protect it.
O
- Opportunity cost
- The value of the work you couldn't take on because the team was busy with something else.
- Every hour spent on a low-margin or over-serviced project is an hour not spent on a higher-margin one. The cost is invisible on the P&L but it is the reason cleaning up underwater projects often raises agency margin faster than winning new work.
P
- Per-role rate
- Pricing time at a different rate for each role (designer, developer, strategist) instead of a single blended figure.
- Per-role rates make the margin on each hour explicit and stop senior time from being undervalued. The trade-off is more complex quoting; many agencies start blended and migrate to per-role once they outgrow the simpler model.
- Productized service
- A service packaged with a fixed scope, price and turnaround, sold like a product.
- Productized services make delivery repeatable, but their thin fixed margins leave no room for hidden over-servicing, so tight profitability tracking is essential.
R
- Realization rate
- The share of worked hours that actually get billed to clients.
- Hours lost to scope creep, rework or admin lower the realization rate and quietly cut into margin even when utilization looks high.
- Retainer
- A recurring fee a client pays for an agreed scope of ongoing work each month.
- Retainers give predictable revenue, but scope tends to drift over time, so tracking delivered hours against the retainer is key to keeping them profitable.
- Retainer fatigue
- The gradual erosion of margin and energy on a long-running retainer as scope drifts and the team loses momentum.
- Retainer fatigue typically starts a few quarters in: brief lift drops, novelty fades and over-servicing creeps in unnoticed. Real-time hours-against-retainer tracking, plus deliberate renewal conversations, are the standard counter-measures.
S
- Scope creep
- The gradual expansion of a project's work beyond what was originally agreed and priced.
- Scope creep is the most common silent killer of agency margin; catching it in real time lets you re-scope before the project goes underwater.
T
- Tool switching cost
- The capacity lost when team members move between tools and contexts during the day.
- APA switch-cost research suggests up to 40% of productive time can go to frequent task-switching across knowledge work; in agencies, where each switch crosses a full client context, the tax tends to run higher. Consolidating the stack is the most direct lever to reduce it.
U
- Utilization rate
- The percentage of a person's available time that is spent on billable work.
- Utilization is a core agency health metric, but high utilization on unprofitable work still loses money. It must be read alongside realization and margin.
V
- Velocity (sprint estimation)
- The amount of work a team consistently delivers in a sprint, measured in story points or hours.
- Velocity is the calibration loop for estimates: once a team has run a few sprints, its measured velocity is a more reliable input to forward planning than any individual's gut feel.
W
- Work in progress (WIP)
- Work that has been delivered or started but not yet invoiced to the client.
- Unbilled WIP ties up cash. A closed-loop system shortens the gap between delivering work and getting paid for it.
