Every agency term, in plain English.

The operations, pricing and client terms agencies use every day - retainers, SOWs, scope creep, MRR, utilisation and more. Each one is a plain-English definition with a real example, a formula where it helps, and links to the tools and templates that put it to work.

Terms starting with C

Capacity planning

Matching the team's available billable hours to the work in the pipeline, to avoid both overload and idle time.

read →

Case study

A short story of a client result - the problem, what the agency did, and the outcome - used as proof to win similar work.

read →

Cash flow

The timing of money moving in and out of an agency. A profitable agency can still fail if cash runs out before clients pay.

read →

Change order

A written, approved record of any change to a project's scope, timeline or fee before the extra work begins. The antidote to scope creep.

read →

Churn

The rate at which clients (or recurring revenue) leave over a period. For agencies, lower churn compounds into far higher lifetime value.

read →

Client onboarding

The process of welcoming a new client - collecting assets and access, setting expectations and kicking off - so delivery starts fast and churn risk drops.

read →

Client portal

A secure, branded space where a client logs in to see deliverables, files, invoices and updates instead of chasing them over email.

read →

Client retention

The share of clients an agency keeps over a period - the flip side of churn, and the foundation of stable, compounding revenue.

read →

Client status report

A regular update that shows a client what has progressed, what is next, and any risks or decisions needed - so they stay informed without chasing.

read →

Content calendar

A schedule of what content will be produced and published, when and where - the plan that keeps an ongoing content engagement on track.

read →

Cost of delivery

The direct cost of producing client work - mostly the billable time of the people doing it, plus any project-specific expenses.

read →

Cost-plus pricing

Setting a price by taking the cost to deliver and adding a fixed markup or margin on top. Simple, but it ignores the value the work creates for the client.

read →

Creative brief

A short document that aligns an agency and client on the goals, audience, message and constraints of a creative project before work begins.

read →

Cross-sell

Selling an existing client a different, complementary service alongside what they already buy - widening the relationship.

read →

Customer acquisition cost (CAC)

The average cost of winning a new client, including sales and marketing time and spend. Compared against lifetime value to check that growth is profitable.

read →

Customer lifetime value (LTV)

The total revenue an agency expects to earn from a client over the whole relationship. A core input for how much you can afford to spend winning clients.

read →

Terms starting with R

RACI

A responsibility matrix (Responsible, Accountable, Consulted, Informed) that clarifies who owns what on a project - useful for client and internal clarity.

read →

Rate card

A published list of an agency's standard hourly or daily rates by role, used as a starting point for quotes and negotiations.

read →

Realization rate

The share of worked hours that actually get billed and paid, after write-offs and discounts. Where planned revenue leaks away before it reaches an invoice.

read →

Referral

A new prospect introduced by an existing client or contact - typically the highest-converting, lowest-cost source of agency work.

read →

Request for proposal (RFP)

A formal document a prospective client issues inviting agencies to bid for a project, setting out requirements, scope and selection criteria.

read →

Retainer

A recurring arrangement where a client pays a fixed monthly fee for an agreed set of services or capacity, rather than per-project. Retainers give agencies predictable revenue and clients priority access.

read →

Retrospective

A structured review after a project or sprint, where the team reflects on what went well, what did not, and what to improve next time.

read →

Revenue per employee

Total revenue divided by the number of full-time staff - a quick benchmark of how productively an agency turns people into income.

read →

Revenue run rate

A projection of annual revenue based on current performance - taking a recent period and extending it across a full year.

read →

Revision round

One agreed cycle of client feedback and changes on a deliverable. Capping the number of rounds is how agencies stop endless tweaking.

read →

Terms starting with S

Sales pipeline

The set of potential deals an agency is working, organised by stage from first contact to signed - a forward view of likely new revenue.

read →

Scope creep

The gradual expansion of a project beyond its agreed scope without matching changes to time or fee - the most common margin killer for agencies. Controlled with explicit out-of-scope clauses and change orders.

read →

Scope of work

The specific work included in an engagement - the deliverables, boundaries and exclusions. A clear scope is the main defence against scope creep.

read →

Service catalog

A defined menu of the services an agency offers, often with set scopes and prices - making it clear what clients can buy and for how much.

read →

Service level agreement (SLA)

A commitment to defined service standards - like response or turnaround times - usually attached to a retainer or support arrangement.

read →

Sign-off

A client's formal approval that a deliverable or stage is accepted - the agreed point at which it is considered done.

read →

Sprint

A short, fixed block of time - often one or two weeks - in which a team commits to completing an agreed set of work.

Standard operating procedure (SOP)

A documented, step-by-step process for a recurring task, so it is done the same way every time regardless of who does it.

read →
