Retainer or Project? An Agency Pricing Guide

Most creative and digital agencies under-price the retainer, over-scope the project, and end the year wondering where the margin went. The pricing decision is not retainer or project. It is which part of every engagement is which.

Agency pricing is one of the most contested topics in services. Half the industry argues retainers are the only way to predict revenue. The other half argues projects are the only way to scope properly and protect margin. The truth is messier and more useful: most engagements are part retainer and part project, and the pricing problem is mostly about labelling each part correctly.

A clean agency proposal lists the retainer block (the recurring monthly work) and the project block (the one-off pieces) as two separate sections, each with its own deliverables, fee, and acceptance trigger. Holding both blocks as free quote templates means the client signs once, you invoice monthly for the retainer and per milestone for the project, and the margin on each part is visible to both sides. If you have read the IT support quoting guide, the structure here is similar but with creative outputs instead of help desk tickets.

What lives on the retainer side

The retainer is for work that recurs every month at roughly the same volume: 4 blog posts, 12 social posts, 1 monthly report, 2 ad campaigns, weekly stand-ups, ongoing optimisation. Each of those should be a numbered line on the proposal so the client knows exactly what they are getting per month. Vague retainers like 'ongoing SEO support' lose to specific ones like '2 technical SEO audits, 4 link-builds, 4 content briefs, 1 monthly performance report' every time.

Price the retainer at a rate that covers the work in a typical month plus a margin buffer for the lighter months when the client uses less of the allocation. Many agencies aim for an effective hourly rate of $ 100 to $ 250 across the retainer (depending on seniority and discipline), built up from a deliverables basis. State the included hours or deliverables explicitly: 'Retainer covers up to 24 hours of strategic work or the listed deliverables, whichever comes first'.

What lives on the project side

The project block is for one-off pieces that have a defined scope and deliverable: a website redesign, a brand refresh, a launch campaign, an annual report, a video shoot, a strategy and audit. Each project gets its own fee, its own milestone schedule, and its own acceptance criteria. Bundling project work into a retainer is the single biggest source of agency margin loss because you end up doing $ 30,000 of project work inside a $ 6,000 retainer and absorbing the difference.

Project fees are easier to scope when broken into stages: discovery (10 to 15 percent), design (30 percent), build (30 percent), QA (15 percent), launch and handover (10 to 15 percent). Working those percentages through a free quote calculator keeps each stage adding back to the project fee. Each stage triggers an invoice on milestone signoff. Most agencies take a 30 to 50 percent deposit at signature on a project. State that clearly: 'Stage 1 fee invoiced on acceptance, balance per milestone schedule below'.

Ad spend: separate, clearly marked pass-through

Ad spend is not your fee. Ever. Showing it bundled into the retainer makes the retainer look bigger than it is and starts a debate every quarter when spend changes. Show it as a separate line marked 'Ad spend, billed at cost, $ 5,000 per month estimated, charged at actual'. Some agencies pass the ad spend through their accounts (and earn a small handling fee). Some have the client pay the platform direct. Either is fine; what matters is that the proposal makes which model you use crystal clear.

If you charge a percentage management fee on ad spend (typical for paid media at 10 to 20 percent of spend), state it as a third line: 'Media management fee: 15 percent of monthly ad spend'. The client sees the fee fee, the spend, and the management fee separately. There is no quarterly argument about what is included.

The discovery or audit, before the main retainer

Most successful agency engagements start with a paid discovery or audit phase, not a free strategy call. Charge for it: a 1 to 4 week strategy and audit at a fixed fee (typically $ 1,500 to $ 12,000 depending on scope and discipline). Deliverables: keyword research, competitor analysis, content audit, technical recommendations, a roadmap document, and a recommendation on the right retainer or project shape.

A paid audit filters the prospects, demonstrates value, and de-risks the larger commitment. If the client signs the retainer afterwards, some agencies credit the audit fee against month one (state that on the audit proposal so it is part of the close). The free strategy call era is over for most agencies that take their P&L seriously. The reasoning is the same as why tradespeople lose jobs: free work signals zero value.

Variations: scope creep is the agency margin killer

The classic agency margin death is a client who 'just' wants one more thing every month. One more email campaign. One more landing page. One more revision round. None of it scopes formally; all of it absorbs into the retainer. By Q3, the retainer is delivering twice the agreed work for the same fee, and the team is burnt out.

The fix is a written variation process. Anything outside the retainer's listed deliverables is a variation. Issue a one-line variation proposal: scope, fee, lead time. Get a signed sign-off before doing the work. Most clients will agree to a small fee for a small extra; few will admit they expected it for free if the variation arrives in writing. The process protects margin without damaging the relationship.

The deposit conversation

On retainers, invoice the first month upfront on signature. Subsequent months go out on the same date each month. On projects over $ 1,500, take 30 to 50 percent at signature, balance per milestone. State both clearly on the proposal so the deposit conversation is settled at acceptance, not at invoicing. The client commits to the engagement when they sign, not when the first statement arrives.

On longer projects (websites, brand identity sprints), some agencies take a deposit, an interim payment at design freeze, and the balance at launch. Three invoices, three clear milestones. The cash flow on a 12-week project is dramatically better than waiting until launch to bill the whole thing.

The bottom line

Agency pricing is not a retainer-or-project debate. It is a labelling problem. Every engagement has recurring work and one-off work. Price each side separately, list deliverables, mark ad spend as pass-through, charge for discovery, write variations down. The agencies that grow are the ones whose proposals make these distinctions visible to the client. The ones that struggle are the ones still arguing about whether 'one more email' is included.
