A social media management agency runs your channels for a monthly fee, and the business hiring one should decide three things before the first post: which channels are worth paying for, in whose name the accounts sit, and what the monthly report measures. Followers and impressions are the agency's metric; enquiries, sales and the cost of each are yours. The U.S. Bureau of Labor Statistics, cited below, puts the median pay for market research analysts and marketing specialists at $78,760 in May 2025, which is the hire the retainer is compared with on the worksheet on this site, on the hours the channels actually need.
Choose the channels by where the customers are
A business-to-business firm on a consumer channel is paying for a presence nobody who buys from it will see. The brief names the channels and the hours each gets; the agency proposes against them rather than proposing every platform it can bill for, and the scorecard checks the match.
Keep the accounts in the business's name
Every account is owned by the business with the agency as a manager, so the day the retainer ends the channels stay. An agency that sets up accounts under its own login has built the exit cost into the fee; the scorecard marks it down and the retainer record states the ownership.
Measure what the business sells
Enquiries, bookings, sales and their cost per channel, reported monthly against the retainer, are the figures that justify the fee; reach and followers are the figures that justify the agency. Retainvia Pro holds the report definition in the brief and records what was delivered against it.
