Retainer pricing vs hourly rates: how to make the switch
Why more service businesses bill a monthly fee instead of hours, and how to price, pitch and write one.
On this page
A retainer replaces hours with a fixed monthly fee for a defined scope or for guaranteed access. It beats hourly billing when the work repeats and the client wants you on call. Price it above your hourly maths, cap the scope in writing, and invoice it on the same day every month.
Why hourly billing breaks for repeat clients
Hourly billing ties your income to the clock, and the clock is a poor measure of what you did. Three things go wrong.
Faster work earns you less. If you get quicker, whether through experience or better tools, the same result takes fewer hours and the invoice shrinks. You are penalised for improving.
The conversation turns into time. Clients start asking how many hours a task took, not whether it solved their problem. That pushes you toward defending minutes.
Income swings with the calendar. A month with two holidays pays less than a month with none, and a client who delays feedback delays your income.
Retainers fix part of this, not all of it. The Leancept article on retainers warns that hour-based retainers are essentially cost-plus pricing, which makes value-based pricing hard. That matters later, when you choose a structure.
What the data says
The best figures come from agencies, and they point one way. SparkToro's State of Digital Agencies 2025 survey found that 85% of agencies prefer retainer-based client work, up from 81% in 2024. Among them, 49% charge between $1,000 and $5,000 a month and 31% charge $5,000 to $10,000. 31% work with clients for more than three years.
A statistics roundup that cites a 2025 Focus Digital analysis puts annual client churn at 18% for retainer-based agencies and 42% for project-based ones. Treat that as a secondhand number from an agency-focused source, but the roundup is clear about where it comes from. The direction matches common sense: a client who pays monthly has already decided to keep you.
For freelancers, the problem retainers solve is the income swing. Ruul's blog, quoting the 2025 freelancermap Freelancer Study, says 39% of freelancers name fluctuating income as one of their greatest professional challenges, and 58% name finding projects as the greatest. Ruul sells payments software, so read its framing as argument, not neutral data.
Scale matters too. Upwork's 2025 Future Workforce Index, as reported by Small Business Trends, found that 28% of US knowledge workers, roughly 20 million people, work independently, and those who earn only from freelancing report a median income of $85,000. More people competing for projects is a reason to build recurring work.
Four retainer shapes
Not every retainer is the same. Pick the shape that matches what the client is really buying.
Availability
The client pays for guaranteed access: a set number of hours a month or a promised response time. Unused hours expire in most deals. It suits advisers, consultants and on-call specialists who sell judgement, not output.
Scope of work
The client pays for a defined set of recurring deliverables, such as four articles, two campaigns and a monthly report. The work is bounded and the hours are yours to manage. It suits content, design, bookkeeping and support work with a stable shape.
Strategic ownership
The client pays for you to own a function or a goal, such as their email programme or their booking process. There is no hour count. You are accountable for the result, and the fee reflects that.
Base plus performance
A fixed fee covers the work, and a bonus ties to a measurable result such as leads or revenue. It only works when the numbers can be attributed cleanly. If tracking is sloppy, skip this shape.
The common mistake is choosing the wrong shape. An adviser on a scope-of-work retainer ends up writing deliverables nobody asked for. A designer on an availability retainer sits idle in a quiet month and still gets blamed for slow turnarounds.
A pricing rule you can adjust
Start from your hourly rate, multiply by the hours the client really uses, then add a premium. This is a rule of thumb, not a survey result, and you should adjust it to your market.
Say you charge $120 an hour and a client takes about 20 hours a month. That is $2,400. A retainer also limits your freedom to take other work, so add 10% to 25%. The retainer fee lands between $2,640 and $3,000. Pricing it at $2,400 means you give the premium away.
Two checks before you quote:
- Does the fee still make sense if the client uses none of it one month? If the answer is no, the scope is too loose.
- Does it cover a real buffer for the days the client asks for something extra?
If you are not sure of your base rate, the freelance pricing guide walks through it. Leancept suggests selling retainers in tiers, so you can offer a lighter and a heavier package and let the client choose.
How to pitch a retainer to a project client
The best moment is right after a delivery that went well. The client trusts you, the results are fresh, and the next problem is easy to name.
A pitch that works names the next problem, proposes a shape and gives a price. For example: "The launch went well. The next risk is that the site goes stale. I can take over monthly updates and reporting for $X a month, with a short call each quarter. Want me to send the agreement?"
A pitch that fails is vague: "Would you like me to help on an ongoing basis?" There is no shape and no price, so the client says thanks and moves on. The guide to converting a one-off client into a retainer has more scripts for this step.
What to write into the retainer contract
Most retainer fights come from five missing lines.
- Scope and exclusions. List what is included each month and what is not.
- Unused hours. State whether they roll over, roll over with a cap or expire.
- Overage. Name the rate for extra work, so a "quick extra" has a price.
- Notice period. Thirty days is typical for small retainers, and larger engagements often run 60 to 90, according to the Ruul article above.
- A review date. Check the scope every quarter and adjust the fee once a year.
Leancept also suggests a fair use clause so you can renegotiate if the work takes longer than planned. Put the whole thing in a one or two page document before the first invoice. Have a lawyer check the wording for your situation.
Where retainers go wrong
Three failure modes show up again and again.
Scope creep is the biggest. In month one the scope is clean. By month six you are doing three times the work for the same fee, because each "quick thing" felt too small to price. Log every extra request, and quote it.
Treating the fee as passive income is next. Leancept notes that routine work can lower quality, and that retainers can hide client dissatisfaction. A quiet client is not always a happy one, so schedule check-ins.
Concentration risk is the third. If one client is most of your revenue, losing them is a crisis. Spread the income across several clients, and keep any single retainer to a share you could survive losing.
Late payment can also hurt a retainer more than a project. In Remote's 2025 Contractor Management Report, 85% of freelancers said they have had invoices paid late at least some of the time, and about 21% are paid late or not at all more than half the time. A fixed monthly invoice with a clear due date and automatic reminders is the best defence.
How Delivvo runs a retainer without the admin
A retainer is simple to agree and tedious to run: the monthly invoice, the reminder, the scope log, the files. Delivvo handles those parts so the work stays about the client.
- Offer tiers in a proposal. Build the quote from packages and add-ons, such as a base retainer, a heavier tier and extra hours at your overage rate. The client picks one.
- Send the agreement from the same link. Your scope, exclusions and notice period go into a contract template you edit. The client signs with a typed or drawn signature, and you get a signing record and an archived PDF.
- Set up the monthly invoice. Recurring invoices send the retainer fee on a schedule, with a sequential number and a due date. For a retainer with a starter fee, a payment schedule can hold up to 12 payments.
- Let reminders chase. A late payment rule sends a reminder at 7, 14 and 30 days and stops as soon as the invoice is paid.
- Keep the work in one place. The client portal holds files, versions, approvals, messages and documents, and the client opens it with a one-time code, no password.
- Bill extras on their own invoice, so overage never gets lost in a chat.
Clients pay through your own gateway, so Delivvo takes 0% and is never the merchant of record. Each invoice also carries a verification code. The recurring invoices page shows how the monthly send works, and the guide to recurring payments covers the setup in detail.

FAQ
How do I price a retainer if I have only billed hourly?
Take your hourly rate, multiply by the hours the client usually needs, and add 10% to 25% for the loss of flexibility. Present the result as one flat fee, and keep the hour maths to yourself.
What if the client wants to keep paying hourly?
Offer a project fee instead of an hourly rate when a retainer does not fit. A project fee fixes the scope and hides the hours. If the client is a good fit for recurring work, hold the retainer line and explain what they get: priority access and a known monthly cost.
How many retainer clients should I have?
There is no survey-backed number. A practical rule is to hold enough clients that losing one would hurt but not sink you. Leancept warns that losing a retainer can be severe if you rely on only a few.
Should unused hours roll over?
Decide before you sign and write it down. Expiring hours protect your schedule. Capped rollover keeps clients happy without letting a pile of hours build up.
What notice period should a retainer have?
Thirty days is typical for smaller retainers, according to the Ruul guide. Larger engagements often use 60 to 90 days. Choose a period long enough that you can replace the income.
