Agency glossary: Business terms defined
Plain-English definitions of the pricing, billing, project and client terms agency owners use every day, with formulas and worked examples.
Understanding agency terminology
This agency glossary defines the terms that come up when you price, sell and deliver client work: retainers, billable utilization, scope of work, markup and margin, white-label portals and more. Agency work mixes project management, finance, sales and client service vocabulary, often in the same conversation, and a loose definition of "scope" or "billable" is how disputed invoices start.
Each entry starts with a one-sentence definition, then shows how the term applies in an agency, usually with a formula or worked example, and links to related terms. Terms are grouped by category (billing, project management, client management and more) and listed alphabetically below.
Use it when you write proposals and contracts, onboard new team members, or need to explain a metric such as utilization or project margin to someone outside finance.
Agency Operations
Client portal
A client portal is a secure, branded website where an agency's clients log in to see project status, share files, approve work, submit requests, message the team and pay invoices.
Billable utilization
Billable utilization is the share of a person's available working hours spent on work a client pays for: billable hours divided by available hours, times 100.
Scope creep
The gradual expansion of project requirements beyond the original agreement, often without corresponding budget or timeline adjustments. Scope creep is one of the leading causes of project overruns and profit erosion.
Retainer agreement
A retainer agreement is the contract that sets out an ongoing, usually monthly, arrangement in which a client pays a recurring fee for an agreed amount of an agency's time, deliverables or availability.
Productized services
Services that are standardized, packaged, and sold like products with fixed pricing, defined deliverables, and efficient delivery processes. Productized services reduce sales complexity and improve scalability.
Agency markup
The percentage or fixed amount added to vendor costs when agencies purchase services or products on behalf of clients. Markup compensates agencies for procurement, management, and risk.
Statement of work (SOW)
A detailed document that defines project scope, deliverables, timelines, milestones, and terms. A well-written SOW prevents scope creep and sets clear expectations for both agency and client.
Project profitability
The financial performance of individual projects, measured by comparing revenue to total costs (labor, overhead, materials). Tracking project profitability helps agencies identify profitable vs. unprofitable work and improve pricing.
Change order
A formal document that modifies the original project agreement when scope, timeline, or budget changes. Change orders protect agencies from scope creep by making scope changes visible and billable.
Capacity planning
The process of forecasting resource needs and ensuring you have the right people available at the right time to meet client demand. Effective capacity planning prevents overcommitment and underutilization.
Key performance indicator (KPI)
Measurable metrics used to evaluate success against business objectives. Agencies use KPIs to track operations, client outcomes, and business health.
Freelancer vs contractor
Distinct classifications for independent workers with different legal, tax, and relationship implications. Understanding the difference affects how agencies hire, manage, and classify talent.
Agency tech stack
The collection of software tools and platforms an agency uses to run its business, including project management, CRM, billing, communication, and design tools.
Agency management software
An all-in-one software platform designed to manage the core operations of an agency, including project management, client relationships, billing, time tracking, and reporting.
Agency Workflow Automation
The use of software and systems to automate repetitive agency tasks such as client onboarding, invoice generation, status updates, and approval routing.
White-label portal
A white-label portal is a client portal that runs on a third-party platform but shows only your agency's brand: your logo, colors and domain, with the provider's branding removed.
Agency Benchmarks
Agency benchmarks are reference figures for metrics such as net margin, project margin, utilization, revenue per employee and client retention, used to compare an agency with similar firms.
Client concentration risk
The financial vulnerability that arises when a disproportionate share of agency revenue comes from a small number of clients, creating dependence that threatens business stability.
Fractional services
Part-time executive or specialist services where an agency provides senior-level expertise on a fractional basis, giving clients access to talent they could not afford full-time.
Managed services
Ongoing, outsourced operational services where an agency takes full responsibility for managing a specific function (such as website hosting, IT support, or marketing operations) on behalf of a client.
Billing & Finance
Billable hours
Hours worked on client projects that can be billed to clients, as opposed to internal, administrative, or non-billable work. Tracking billable hours accurately is essential for agency profitability and client billing.
Recurring revenue (MRR/ARR)
Predictable, repeating revenue from ongoing client relationships like retainers, subscriptions, or service agreements. Recurring revenue provides financial stability and makes agencies more valuable businesses.
Net 30 payment terms
Payment terms requiring clients to pay invoices within 30 days of the invoice date. Net 30 is standard in B2B, but agencies should consider shorter terms to improve cash flow.
Value-based pricing
Pricing based on the value delivered to clients rather than time spent or costs incurred. Value-based pricing allows agencies to capture more value and align pricing with client outcomes.
Accounts receivable
Money owed to your agency by clients for work completed but not yet paid. Managing accounts receivable effectively is critical for cash flow and agency financial health.
Profit margin
The percentage of revenue that remains as profit after all costs are deducted. Profit margins measure agency financial health and sustainability.
Cost-plus pricing
A pricing method that adds a markup percentage to costs to determine price. Cost-plus pricing ensures costs are covered but may not capture full value.
Agency profitability
Agency profitability is how much of an agency's revenue it keeps after all costs, measured as net margin for the business and as margin per project and per client.
Agency overhead
The ongoing business expenses that are not directly tied to delivering client work, including rent, software, insurance, admin salaries, and utilities.
Invoice factoring
A financial arrangement where an agency sells its unpaid invoices to a third-party company at a discount in exchange for immediate cash.
Recurring billing
An automated billing process where clients are charged on a regular schedule (weekly, monthly, quarterly) for ongoing services like retainers, subscriptions, or maintenance plans.
Agency revenue model
The pricing and billing structure an agency uses to charge clients for its services, such as hourly billing, project-based fees, retainers, or productized services.
Client acquisition cost (CAC)
The total cost an agency incurs to acquire a new client, including marketing, sales, and business development expenses divided by the number of new clients won.
Revenue per employee
A productivity metric calculated by dividing an agency's total revenue by its number of full-time equivalent employees, indicating how efficiently the team generates income.
Effective hourly rate
The actual revenue an agency earns per hour of work performed, calculated by dividing total project revenue by actual hours spent, revealing true project profitability regardless of billing model.
Project margin
The profitability of an individual project, calculated as the difference between project revenue and all direct costs associated with delivering it, expressed as a percentage.
Annual recurring revenue (ARR)
The annualized value of predictable, recurring revenue from retainer agreements, managed services, and subscription-based client engagements.
Agency gross margin
Agency gross margin is the percentage of revenue left after direct delivery costs (billable staff time, freelancers and project-specific expenses) and before overhead.
Rate card
A published document listing an agency's standard pricing for services, typically organized by role, service type, or deliverable, used as a starting point for client negotiations.
Blended rate
A single averaged hourly rate that combines the different billing rates of team members working on a project, simplifying pricing for clients while reflecting the mix of roles involved.
Financial
Burn rate
The rate at which a company spends its cash reserves over time, typically measured monthly. Burn rate indicates runway (how long a business can operate before running out of money) and is critical for agency financial planning.
Markup vs margin
Markup is the percentage added to cost to set price; margin is the percentage of price that is profit. Confusing them leads to pricing errors: they are calculated differently.
Sales & Marketing
Pitch deck
A presentation used to win new business by showcasing an agency's capabilities, approach, and differentiators. Effective pitch decks tell a compelling story and differentiate the agency from competitors.
Agency partnerships
Strategic relationships between agencies for referrals, subcontracting, or joint delivery. Partnerships extend capabilities and create new revenue opportunities.
Pipeline velocity
The speed at which prospective clients move through an agency's sales pipeline, measuring how quickly opportunities convert from initial contact to signed contracts.
Client Management
Client Onboarding
The process of welcoming new clients, setting expectations, gathering information, and establishing workflows. Effective onboarding sets the foundation for successful client relationships.
Client Offboarding
The structured process of concluding client relationships, transferring deliverables, closing accounts, and gathering feedback. Professional offboarding protects your reputation and creates opportunities for future work.
Client retention rate
The percentage of clients who continue working with your agency over a given period. High retention rates indicate strong relationships and reduce the need for constant new client acquisition.
White-Label
White-label describes a product or service made by one company and sold by another under the seller's own brand. Agencies use it in two ways: reselling services delivered by a partner, and running software branded as their own.
Client lifetime value (CLV)
The total revenue a client generates over the entire relationship with your agency. Understanding CLV helps agencies make better decisions about acquisition costs, service levels, and retention efforts.
Net promoter score (NPS)
A metric that measures client satisfaction and loyalty by asking how likely clients are to recommend your agency. NPS helps agencies understand client sentiment and identify areas for improvement.
Service level agreement (SLA)
A contract that defines the level of service a client can expect, including response times, availability, and performance standards. SLAs set clear expectations and protect both agency and client.
Account management
The function responsible for maintaining and growing client relationships. Account managers serve as the primary client liaison, ensuring satisfaction, identifying opportunities, and managing the overall client experience.
Agency of record (AOR)
The primary agency relationship where a client grants exclusive or preferred status for a service category. AOR relationships provide significant revenue and strategic importance.
Client brief

Client health score
A composite metric that combines multiple signals, such as communication frequency, payment timeliness, project satisfaction, and engagement level, to predict client retention risk.
Project Management
Agile methodology
An iterative, collaborative approach to project management that emphasizes flexibility, client collaboration, and delivering value incrementally. Agile helps agencies adapt to changing requirements and deliver better outcomes.
Project kickoff
The initial meeting or phase that launches a project, aligns stakeholders, establishes processes, and sets expectations. Effective kickoffs set projects up for success by ensuring everyone starts aligned.
Milestone billing
A billing approach that ties payments to project milestones or deliverables rather than time periods. Milestone billing improves cash flow and aligns payments with value delivery.
Resource allocation
The process of assigning team members, tools, and budget to projects and tasks. Effective resource allocation ensures the right people work on the right projects at the right time.
Time and materials (T&M)
A billing model where clients pay for actual time worked and materials used, typically with hourly rates and reimbursement for expenses. T&M provides flexibility but requires clear scope management.
Creative brief
A document that captures project objectives, audience, messaging, deliverables, and constraints to align the creative team and client. A well-written creative brief prevents misalignment and reduces revision cycles.
Deliverables
Tangible outputs or work products that agencies produce and deliver to clients. Clearly defining deliverables in scope documents prevents scope creep and ensures mutual understanding of project outputs.
Discovery phase
The initial project phase where agencies gather requirements, understand client needs, and define scope. A thorough discovery reduces project risk and sets the foundation for successful delivery.
Brand guidelines
Documentation that defines how a brand should be represented across all touchpoints. Brand guidelines ensure consistency and protect brand integrity in agency creative work.
Sprint planning
An agile ceremony where the team commits to work for the upcoming sprint. Sprint planning aligns the team on scope, priorities, and capacity for the iteration.
Kanban
A visual workflow management method using boards and columns to represent work stages. Kanban emphasizes continuous flow and limiting work in progress.
Waterfall methodology
A linear project approach where phases proceed sequentially: requirements, design, build, test, deliver. Waterfall works well for fixed-scope projects with clear requirements.
Scope of work
A scope of work is the part of a project agreement that defines the work itself: the deliverables, quantities, what is included and excluded, assumptions and acceptance criteria.
Minimum viable product (MVP)
The simplest version of a product that delivers core value and enables learning. Agencies use MVP thinking for client projects and internal product development.
Client approval workflow
A structured process for routing deliverables to clients for review, collecting feedback, managing revisions, and obtaining formal sign-off before work progresses.
Project scope
The defined boundaries of a project, including what will be delivered, what will not be delivered, timelines, and success criteria.
Project kickoff meeting
The initial meeting between the agency team and client at the start of a project, used to align on goals, timelines, roles, communication, and next steps.
Business Development
Request for proposal (RFP)
A formal document from potential clients soliciting proposals from agencies. RFPs outline project requirements and evaluation criteria, and responding effectively requires strategic positioning.
Sales pipeline
The stages that potential clients move through from initial contact to closed deals. Managing sales pipelines helps agencies forecast revenue, prioritize opportunities, and improve conversion rates.
Proposal win rate
The percentage of proposals that result in won deals. Tracking win rates helps agencies understand sales effectiveness and identify improvement opportunities.
Discovery call
A sales conversation focused on understanding client needs, challenges, and goals before proposing solutions. Effective discovery calls improve proposal quality and win rates.

Sales techniques for expanding client relationships: upselling increases value of current work, while cross-selling adds complementary services. Both increase revenue and strengthen relationships.
Churn rate
The percentage of clients who stop working with your agency over a given period. Reducing churn is critical for growth because retained clients are more profitable than constantly acquiring new ones.
Agency new business
The function and process of acquiring new clients for an agency, encompassing lead generation, pitching, proposals, and closing deals.
