Before offering ongoing monthly support, define the work included, the capacity you can reserve and what happens when requests exceed it. Separate a response promise from a completion promise. Then decide how unused capacity, client delays and extra work will be handled before either side relies on the monthly arrangement.
A monthly fee alone does not describe a service. One client may expect a fixed list of deliverables. Another may think it buys immediate access whenever something comes up. Those expectations need to meet in a written offer, not in the first busy week.
AIGA’s payment-strategy guidance for design businesses distinguishes an ongoing retainer relationship from simply spreading a project’s fee across monthly payments. That is a useful starting question: are you offering recurring work or installments on a finite project?
The worksheet below is an editorial planning tool for solo service founders. It is not a contract, a recommended price or proof that a retainer will be profitable.
Key takeaways
- Name the recurring service and what the monthly fee covers.
- Plan around capacity you can actually reserve after existing commitments.
- Define response and completion separately, including dependencies.
- Agree on overflow and unused capacity instead of inventing the rule when it becomes inconvenient.
Choose the unit you are promising
Start with the work, not the word “retainer.” A recurring offer might cover a defined set of outputs, a specified amount of working time or access to a bounded advisory service. Explain which one the client is buying.
An output-based offer still needs limits: quantity, complexity, review rounds and client inputs. A time-based offer needs a record of what uses the allowance, including meetings and revisions if those count. An access-based offer needs an explanation of the channel, availability and limits of that access.
Avoid combining these in a way that quietly promises everything. A fixed monthly fee plus unlimited deliverables plus immediate turnaround is not a capacity plan.
AIGA’s pricing-model guide stresses the importance of defining included and excluded work in fixed-fee proposals. For an ongoing service, apply the same discipline to each recurring period.
Make a capacity budget before making a sales promise
Use your actual schedule and delivery records. Allow for existing clients, business administration, sales work, time off and a buffer for variation. Do not treat every working hour as available to sell again.
Here is a deliberately simple hypothetical month, not an industry benchmark:
- Total working time in the example (Hours: 140)
- Existing commitments (Hours: 70)
- Administration and sales (Hours: 25)
- Buffer reserved for uncertainty (Hours: 15)
- Remaining planned capacity (Hours: 30)
If the proposed retainer needs 24 hours, this example leaves six hours of unallocated capacity. It does not leave 30 hours for another client. If the likely work regularly exceeds the 24-hour plan, change the scope, timing or resources before selling it.
Hours are only one constraint. Work may require a particular review window, specialist or client input. Thirty scattered hours do not necessarily create a two-day block for an urgent launch.
Separate acknowledgement from delivery
“We respond within one business day” and “we finish within one business day” are different promises. Write down which one you mean, the business hours it uses and what happens outside those hours.
For completion, account for the request’s size, queue position and required inputs. State how a delivery date is confirmed. Do not let a quick acknowledgement sound like acceptance of any deadline the client names.
If urgent work is available, describe the approval and scheduling process. Do not imply guaranteed emergency coverage unless you have actually planned and agreed to provide it.
Complete the monthly-offer worksheet
Use these fields to prepare a discussion with the client. Turn the agreed decisions into the appropriate written terms for your business.
- Service: What recurring problem are you taking responsibility for?
- Included work: Deliverables, allowance or bounded access, with quantities and limits
- Excluded work: What requires a separate discussion or quote?
- Capacity: What can you reserve, and what existing commitments constrain it?
- Requests: Who can submit work, through which route, with what information?
- Response: When will a request be acknowledged or assessed?
- Delivery: How will a completion date be confirmed, including review dependencies?
- Overflow: What happens when the allowance is used or the queue is full?
- Unused capacity: Does it expire, carry forward or receive another treatment?
- Client delays: What happens when required inputs or approvals arrive late?
- Review: When will both sides compare the arrangement with the actual work?
- Ending or changing it: What notice and transition process applies under the agreed terms?
The worksheet does not decide those terms for you. There is no automatic rule that unused hours must roll over, disappear or be refunded. The choice needs to be clear before the client buys, with professional review where needed.
Use a busy-month test
Imagine a client submits a large request near the end of the period, after most planned capacity is used. Can your offer explain what happens without an improvised exception?
For example, a hypothetical 24-hour support arrangement has used 22 hours. A new request is estimated at six hours. The founder checks whether it fits the included work, explains the capacity shortfall and discusses an approved extra allocation, a smaller request or a later delivery window. The request itself is not approval for an extra charge.
Now test the opposite month: the client submits very little. Can you point to an agreed unused-capacity rule and explain what the fee covers? If not, the offer is unfinished even if the price looks attractive.
For changes within an active project, GREY Journal’s revision-versus-scope-change worksheet addresses how to assess a particular request. This worksheet comes earlier: it helps define what the recurring arrangement can promise in the first place.
Frequently asked questions
Is every monthly payment a retainer?
No. A monthly payment can be an installment on a fixed project. Describe the underlying arrangement rather than relying on the label.
Should unused hours roll over?
There is no rule supplied by this worksheet. Agree on a clear treatment that fits the service and capacity plan, then reflect it in the applicable terms.
Does a fast response mean fast completion?
Not necessarily. Define acknowledgement and completion separately, and explain how request size, scheduling and client inputs affect delivery.
Does the example tell me what to charge?
No. It is a capacity illustration, not a pricing benchmark or profit calculation. Costs, risk and the actual service still need their own assessment.
Method: AIGA’s design-business guidance informs the distinctions about payment schedules and scope. The capacity worksheet and worked examples are GREY Journal’s editorial synthesis. No client results or profitability test is claimed.
