How Much Does a Marketing Agency Consultant Cost? $750 a Call to $20,000 a Month

Minimum terms, setup fees and runways: the first-year bill

A monthly price is the smaller half of the number. Counted over a first year of 12 months, with each page’s minimum term, setup fee and runway included and no price change, the same lists read like this:

• AMI: one 12-hour pack, $7,500 or $10,000, lasts about a year at one hour-long call a month. Per hour that is $625 for a network member and about $833 for anyone else, against $750 for a single hour bought on its own.
• SAGA: $12,000 for a year of owner coaching, $42,000 for a year of team advisory and $90,000 for a year of embedded consulting. All of it is month-to-month, so the agency can stop sooner.
• Parakeeto, Grow tier at its starting price: $28,987 in the first year on an annual commitment (the assessment plus 12 months, setup waived), or $34,984 without one, once the $5,997 setup fee is added; stopping at the six-month minimum would still come to $22,990. On an annual commitment, the first year at Scale and Thrive starts at $40,987 and $82,987.
• Sakas & Company: $36,000 for 12 months of growth coaching. The 12-month runway on Executive Advisory comes to $96,000 for one leader and $240,000 at the comprehensive tier. The advisory page describes starting with an Agency Value Audit; ask whether that audit is included or billed on top.
• Promethean Research: one payment of $2,300 to $18,700, made before the work starts.

The five lists sell different work, so the year totals rank nothing; they are there so a year gets weighed against a year. Time belongs on the same sheet: Parakeeto’s page expects one to three hours a week from the agency during the assessment, which is 2 to 12 hours across two to four weeks; Promethean Research plans on about three hours per leader; and a one-hour coaching call every week is 52 hours of the owner’s calendar in a year, before any homework.

Gross billings or revenue kept, staff or freelancers: what sets the tier

Two of these price lists move with the size of the agency. Parakeeto sets its monthly tier by trailing 12-month revenue, and Promethean Research sets its fee by full-time-equivalent staff. At an agency, neither number is as plain as it sounds.

An agency that places media or buys production, printing or talent for clients passes that money through. Gross billings can then sit well above the revenue the agency keeps to pay its own people, and the two figures can put the same firm in different tiers. Headcount has the same problem. Take a hypothetical studio with eight employees and six regular freelancers: it is under 10 or between 10 and 24 depending on whether contractors count. Ask, in writing, which revenue figure and which staff count the quote uses, before the quote is accepted.

Leader surveys, the P&L, or the timesheets and SOWs: what each one reads

What separates these offers is what the work is built from. Promethean Research describes a survey each leader fills in, separate one-on-one interviews and a comparison with its own research. Parakeeto describes collecting and cleaning the agency’s data, then building a model of the firm with benchmarks and a historical analysis. SAGA’s Checkup starts from an intake questionnaire, the financials, client roster and team structure the owner shares, and three or four work sessions. AMI’s coaching runs on calls and email, and the Sakas & Company Value Audit looks at valuation, risks and priorities.

Answers tell an adviser what leaders believe is happening; records show what happened. Inside an agency the costly gaps sit between tools, where no single report covers them:

• Retainer hours logged past what the monthly fee assumed, month after month, with no true-up conversation.
• Revision rounds delivered past the rounds the SOW sold, booked to the original job number.
• Extra asks agreed to on a client call, with no change order written.
• Proposals left at “Sent” in the proposal tool, with no win or loss recorded.
• Milestones finished while the invoice waits for late timesheets.
• Invoices bounced by a client’s procurement portal for a missing PO number.

Each one can be counted from the time tracker, the project tool, the proposal log and the accounting file. A coaching format that never opens those can still be the right purchase for leadership, positioning or a sale, but it will not put a monthly dollar figure on any of them.

Our Review against these price lists

The Revenue Review is a fixed $4,500 for two weeks of reading the agency’s own proposals, time entries, SOWs, change orders and invoice dates under an NDA, and it ends in a written report the firm keeps, with each leak priced by the month wherever the records support a figure; it is not coaching, a peer group or monthly finance support. On October 27, 2026, a SAGA Planning Intensive carried the same price, so the comparison worth making is which records each one reads, and the Review page linked below sets out the scope, the payment terms and who it is not for.

Client logins, coded names, time by role: questions only an agency asks

Scope, the total over the term, what the firm keeps and how to leave apply to any hire, and How to Choose an Operations Consultant, listed at the end of this page, covers them. The points below belong to agencies alone:

• Client ad accounts, creative files and client logins stay closed. A review of how the agency runs reads records about the work, never the work itself.
• Client names are coded before anything is exported. A client’s MSA or NDA may limit what the agency can share with a third party, so the agency’s attorney should read those clauses before access is granted. Not legal advice.
• Time data comes back by role and by client, not by named designer or account lead. Finding where the hours go does not require ranking people.
• Benchmarks state their basis: which agencies, what size, which year, and whether the comparison runs on gross billings or on revenue after pass-through costs.
• A margin, a valuation multiple or a revenue figure promised before anyone has opened the timesheets or the P&L is a sales line, not a finding.
• For a peer group or mastermind, the period each payment covers and the cost of leaving are written down before the first meeting.

Three agency problems that need an owner, not an adviser

Some fixes cost nothing but a name. A change order nobody writes because writing it is nobody’s job, a retainer true-up nobody runs at month end, and a timesheet due date nobody enforces each need one owner and a date, not a study. An agency that cannot see how it covers the next payroll needs that decision made before it commissions any report. An agency halfway through moving to a new time tracker or project tool should finish the move first, since a review of half-migrated data describes the migration. Contract language belongs with an attorney, taxes with a CPA, and the sale of the agency with an M&A advisor.

Size matters as well. Of the 13,682 employer firms the Census Bureau classed as advertising agencies in its 2022 Statistics of U.S. Businesses, 4,358, just under a third, reported $1 million or more in receipts. Among public relations agencies the count was 2,230 of 8,157, and among marketing consulting firms 8,293 of 49,047, about one in six. The Review assumes an agency of that size or larger, with five or more billable staff and someone besides the owner doing part of the delivery; an agency below that line hears as much on the 20-minute call.
