Fire the $2,500/month client. The $8,000 one is waiting on the calendar they occupy.
Small retainers look like easy money. They consume the same kickoff, weekly call, Slack thread, and context-switch as an $8,000 account, at a third of the fee. The book gets busy. Margins do not.
1. Count hours per account, not just revenue
Track founder and delivery hours for 30 days by client. Divide retainer by those hours. The $2,500 account that eats 12 hours is a $208/hour job that still requires you to be "on." The $8,000 account at 10 hours is the one worth protecting.
2. Comms load does not scale with fee
A cheap client still wants a recap, a revision, and a "quick question." Those messages fragment the same deep work block you need for the accounts that pay. Cap async channels. If they cannot live inside one weekly touchpoint, they are too expensive at that rate.
3. Small clients train the team to over-serve
When the book is full of low-fee work, "yes" becomes the default because no single ask looks expensive. Scope creeps in 15-minute increments. Write a hard floor: below $X/month, the engagement is a fixed package with no extras, or it is a no.
4. Exit with 30 days notice, a referral, or a paid wind-down
Do not ghost. Send a short note: the book is concentrating on fewer accounts, here is the end date, here is a referral or a 30-day wrap at the current rate. Most will leave quietly. A few will ask to stay at the new floor. That is a raise, not a rescue.
5. Replace with one $8K before you add three $2.5K
Open capacity is a sales target, not a vacuum to fill with whoever says yes. One well-scoped $8,000 retainer returns more margin and fewer threads than three small ones that look like pipeline.
6. Put the floor in writing and enforce it at every renewal
If it is not on the website and in the proposal, the team will keep making exceptions. Exceptions become the book. Review every account against the floor once a quarter and act in that window, not "when things calm down."
Revenue from a bad-fit client is not profit. It is rented capacity you cannot sell to someone who pays.
