How to move a client onto a retainer

If one client already gives you $4,000 in a busy month and $0 in a quiet one, a retainer is the conversation about the quiet month. Ten hours at your project rate of $150 is $1,500 when the work shows up, and nothing when it does not. A retainer at $1,200 a month for those same ten hours is less per hour and more per year, because the $0 months stop being $0. That trade is the whole offer. If you cannot explain it in one sentence, you are not ready to send it.

This is for a freelancer who already has a client worth keeping, not for a cold pitch. You are not inventing loyalty. You are pricing a pattern you can already see. The calendar gaps are the expensive part. A cash flow forecast makes them obvious: two paid months, then three weeks where nothing from that name arrives, then a rush you discount because you are relieved.

Which clients are actually retainer candidates?

A retainer candidate already comes back. Not once, as a favour. Several times, with work that looks similar each time: the monthly report, the edits, the support queue, the campaign that never really ends. If you have to invent a reason for them to need you every month, they are a project client. Leave them as one. A retainer sold to someone who does not have monthly work becomes an awkward subscription they cancel in the first quiet week, and you have trained them to think of you as optional overhead.

They also pay. A client who is slow on project invoices will be slow on a retainer, and now the lateness is monthly. Look at how long they take before you offer to depend on them. If the last three invoices took 40 days, a retainer does not fix that. It repeats it. Sort the payment habit first, or price the retainer with the lag in mind so your forecast still works.

The work has to be something you can describe without a new estimate every time. "Design support, up to ten hours, two rounds on each piece, replies within two working days" is a retainer. "Whatever comes up" is how you end up in their emergencies at your old rate, except now they feel they have already paid. If you cannot list the work in a short paragraph, you are still in project land, and an estimate is the right document.

One more filter: you have to want the work in the quiet months too. A retainer is a promise you show up when their month is dull. If you only like this client when the brief is interesting, do not sell them your ordinary weeks. You will resent the email that is exactly what they bought.

How do you price it so the year is worth having?

Start from the hourly floor you actually need, not from a number that sounds friendly. The freelance rate calculator is the backward sum: income, costs, and the hours you can bill. If that floor is $120, a retainer at $70 is not a relationship. It is a pay cut you will try to escape. The retainer rate can sit a little under the project rate. It should not sit under the floor.

Here is the trade, with the numbers visible. Project rate $150. A typical month with this client is 10 hours, so $1,500, but only in the months they send work. Across a year that might be seven months: $10,500, and five months of nothing from them. A retainer of 10 hours at $120 is $1,200 every month, $14,400 a year. You make less on a busy month and more on the year, and the empty months are no longer empty. That is why the hourly number goes down. You are selling the gap, not discounting the hour because you were embarrassed to say $150.

Write the edges before you write the price into an email. How many hours. What turnaround, in working days, not in "soon." What happens to unused hours: they expire, or a few roll for one month, and they do not pile up. How much notice either of you needs to cancel. One month is enough for most freelance retainers. A retainer you cannot leave is not a retainer. It is a job you forgot to interview for.

Hours over the cap are billed at the project rate, not absorbed to be nice. If you absorb them, the cap was theatre. Say that extra hours need a yes before you start them. The client should be able to read the paragraph and know what they are buying, what they are not buying, and what it costs to stop. Payment terms for that paragraph belong in the same place as your other terms. The examples in payment terms wording are a starting point for the due date, not a script you have to copy.

What do you say, including when they say no?

Have the conversation after a good month, not in the middle of a chase. You are offering a calmer way to keep working, not a rescue for an unpaid invoice. One email is enough. Name the pattern: "The last three months were 12, 8, and 10 hours, with a gap in between." Name the offer: "Ten hours a month, $1,200, invoiced on the 1st, unused hours expire, extra hours at $150 with a yes first, either of us can stop with 30 days' notice." Then ask if they want it from next month. Do not attach a deck.

If they say the hourly number looks high, go back to the year, not to an apology. The project rate costs them more in the months they use you, and nothing in the months they do not. The retainer costs a known amount every month. Some clients want the spikes. That is a fine answer. It is not a reason for you to cut the retainer until it mimics the spikes and keeps the obligation.

If they say no, thank them and leave the project terms standing. Do not go quiet, and do not suddenly become hard to book. A no means they want to keep buying projects. Your next move is a deposit and a clear due date on the next one, which is a different conversation and a useful one. How much to take up front is the piece for that, if the retainer was really a way to stop financing their gaps.

If they say yes, send the short agreement the same day, with the four edges in it: hours, turnaround, unused hours, notice. Invoice the first month before the month starts, not after you have already worked it. A retainer billed in arrears is a project invoice with a nicer name. You wanted the quiet weeks funded. Bill them while they are still in front of you.

Review it after three months. If they use four hours of a ten hour retainer, the fit is wrong and you should say so before you resent it. If they use fourteen and you keep absorbing the extra, raise the cap or bill the overage. A retainer that never gets looked at becomes the old project relationship, plus a feeling that you are not allowed to reprice it. You are. The notice period is how.
