What it is
A retainer is an ongoing monthly agreement where a client pays an agency or consultant a set fee in exchange for a defined set of services or a reserved block of time and capacity. Instead of project-by-project billing, you're paying for consistent access and ongoing work.
Why it matters
Retainers create stability — for both sides. For the agency, predictable recurring revenue allows for better planning and resource allocation. For the client, a retainer means your team already knows your business, your brand, and your history — no re-briefing every time, no losing momentum between projects. Continuity compounds.
The mistake most people make
Signing a retainer without clearly defining what's included. "We'll handle your marketing" is not a retainer scope — it's an open invitation to scope creep and resentment. Every retainer should spell out exactly what is delivered each month, what revision rounds are included, what requires a separate quote, and how performance is measured. Vague retainers breed frustration.
