Why retainers go wrong
A retainer is the most attractive arrangement in freelancing — predictable income, no constant pitching — and the one most likely to quietly turn into unpaid work.
The failure is nearly always the same. The agreement says something like "ongoing design support, $2,000 a month," and nothing else. In month one the client uses roughly what both sides imagined. By month four they've learned that requests are effectively free, so they send more. Your hourly rate quietly halves, and there's no moment where anyone did anything wrong.
A retainer needs a defined limit exactly as much as a project needs a scope. The rest of this page is about what that limit should be and how to word it.
Two models — pick one deliberately
1. Hours-based
The client buys a block of your time each month: "up to 20 hours." Simple to understand, simple to track, and the easiest to defend when it runs out.
Suits: consulting, development, ongoing marketing work — anything where tasks vary and effort is the meaningful unit.
Watch for: clients who start scrutinising your time log. Once every fifteen minutes is under review, the relationship shifts to something closer to employment.
2. Deliverables-based
The client buys a defined set of outputs each month: "four blog posts, eight social graphics, one monthly report." Cleaner to sell, because the client is buying results rather than your hours.
Suits: content, design, and any work with repeatable units.
Watch for: scope creep inside each unit. "One blog post" becomes 2,500 words with three rounds of revisions unless the unit itself is specified.
The hybrid trap: "four blog posts plus ad-hoc support" is the wording that causes the most trouble, because "ad-hoc support" is unlimited by definition. If you want to include flexibility, cap it: "plus up to 3 hours of ad-hoc requests."
The retainer agreement
Not legal advice. This is a practical business document that has not been reviewed by a lawyer. For high-value or long-term arrangements, have a qualified solicitor or attorney review it.
1. Parties and start date
This agreement is between [your name / business] ("the Contractor") and [client] ("the Client"), beginning [date].
2. What's included each month
Each month the Contractor will provide: [either "up to X hours of work on tasks agreed with the Client" or the specific list of deliverables, with each unit defined].
3. What's not included
The following are outside this retainer and would be quoted separately: [e.g. new brand work, website rebuilds, paid media budgets, third-party licences, work for other entities in the Client's group].
4. Unused time or deliverables
Unused [hours / deliverables] do not roll over into the following month.
5. Going over
Work beyond the monthly allocation will be flagged before it is carried out and charged at [rate] per hour, or quoted separately, at the Client's choice.
6. Turnaround and availability
Standard turnaround is [e.g. 2 working days] from request. The Contractor is available [days and hours] and responds to messages within [one working day]. Urgent same-day work is charged at [rate].
7. Fee and payment
The monthly fee is [amount], invoiced on the [1st] of each month and payable within [7] days. Work for a given month begins once that month's invoice is settled.
8. Minimum term and notice
The initial term is [3] months. After that, either party may end the agreement with [30] days' written notice. Fees for the notice period remain payable.
9. Price review
The monthly fee may be reviewed after [6] months, with at least [30] days' written notice of any change.
10. Ownership
Ownership of work produced in any month transfers to the Client once that month's invoice has been paid in full.

Contractor: [name] — Date: __________
Client: [name] — Date: __________
The three clauses that do the work
Clause 4 — no rollover
Without it, a client who uses little in months one and two arrives in month three expecting triple. Rollover turns a predictable arrangement into an unpredictable liability, and it's much harder to remove later than to state at the start.
If a client objects, the honest answer is usually persuasive: the retainer reserves capacity in your schedule, and that capacity was held whether or not it was used.
Clause 5 — flag before, not invoice after
The wording says work beyond the allocation is flagged before it is carried out. That ordering matters. Invoicing for overage the client didn't know about causes far more friction than the overage itself, and it's the fastest way to lose a retainer client.
Clause 7 — payment before the month's work
Invoicing on the 1st and starting once it's settled prevents the most common retainer failure: three months of work delivered against three unpaid invoices, discovered only when the client leaves.
Pricing a retainer
Start from your hourly rate and the hours involved, then decide consciously whether to discount.
A modest discount — often around 10% — is common and defensible, on the basis that guaranteed income is worth something to you and reduces your time spent finding work. A large discount is worth resisting: the client is buying reliability and priority access, which have real value, and a retainer priced too low becomes something you resent by month four.
Price the reserved capacity, not just the hours used. If you're holding twenty hours a month open for a client, that capacity is unavailable to anyone else regardless of whether they use it. That is what they're paying for.
How to propose one
The best moment is immediately after a successful project, while the relationship is warm and the value is visible. Frame it around their continuity rather than your income.
"Now the site's live, most of the value comes from keeping it updated. Rather than quoting each small job separately, I could hold [X hours] a month for you at [amount] — you'd get priority in my schedule and we'd skip the back-and-forth on every request. Worth a look?"
"We'd skip the back-and-forth on every request" is the strongest line there, because the administrative friction of small jobs is a real irritation for clients too.
Common questions
What should a freelance retainer agreement include?
Ten things: the parties and start date, what is included each month, what is excluded, whether unused time rolls over, how work beyond the allocation is handled, turnaround and availability, the fee and payment timing, minimum term and notice period, when the price can be reviewed, and when ownership of the work transfers.
Should unused retainer hours roll over?
Generally no, and it is much easier to state at the start than to remove later. Rollover turns a predictable arrangement into an unpredictable liability, because a client who uses little for two months can arrive in the third expecting triple. The honest justification is that a retainer reserves capacity in your schedule whether or not it gets used.
How much should I charge for a retainer?
Start from your hourly rate multiplied by the hours involved, then decide consciously about a discount. Around 10% is common and defensible, on the basis that guaranteed income has value and reduces time spent finding work. Large discounts tend to produce a retainer you resent by month four.
What is the difference between an hours-based and a deliverables-based retainer?
An hours-based retainer sells a block of your time, which is easy to track and defend when it runs out. A deliverables-based retainer sells a defined set of outputs, which is cleaner to sell because the client is buying results. The risk with deliverables is scope creep inside each unit, so define what one unit actually contains.
How do I propose a retainer to an existing client?
Immediately after a successful project, while the value is visible. Frame it around their continuity rather than your income — priority in your schedule, and no back-and-forth quoting every small request. The administrative friction of small jobs is a genuine irritation for clients too, which makes that the strongest argument.
