Core concepts
Retainer fee
A retainer fee is money paid in advance to reserve a provider’s availability or fund future work. It may be earned for access, drawn down as work is completed, or charged on a recurring schedule. Refund, revenue, and invoice treatment depend on the written agreement, applicable law, and accounting rules.
What a retainer means
A retainer is money a client pays in advance to secure your ongoing availability. It signals commitment from both sides: the client reserves your time, and you agree to be ready to work for them. Retainers are common for consultants, agencies, lawyers, designers, and other service professionals with continuing relationships.
Retainers usually take one of two forms. In a draw-down retainer, the client prepays a balance and you bill your hours or deliverables against it until the balance runs low and is topped up. In a fixed recurring retainer, the client pays a set amount each period for an agreed scope of access or work, whether or not they use all of it.
Retainer fee types compared
The label alone does not decide when money is earned or whether it is refundable. The agreement, jurisdiction, and applicable accounting rules control the legal and accounting treatment, so state the purpose, earning trigger, refund terms, and invoice treatment in writing.
| Arrangement | Purpose | When revenue is earned | Typical refund treatment | Invoice treatment |
|---|---|---|---|---|
| Access/general retainer | Reserve availability or access | As the agreement says the access is provided | Often non-refundable once the reserved period begins, subject to law and contract | Invoice the reserved period and describe the access covered |
| Draw-down or advance-fee retainer | Prepay future hours or deliverables | As work is performed | Unused amounts are often refundable, subject to law and contract | Show work performed, amount applied, and remaining balance |
| Fixed recurring retainer | Provide an agreed scope each period | As each period’s services or access are provided | Often non-refundable for a completed reserved period, subject to law and contract | Issue the fixed charge on the agreed recurring schedule |
| One-project deposit | Partially prepay one defined project or event | As the contract and performance rules require | Depends on cancellation terms, performance, and law | Apply the deposit to the project total and show the remaining balance |
Retainer fee versus a one-project deposit
A retainer reserves availability or funds work over time. A one-project deposit is a partial payment toward a specific job or event and is credited against that project total. Event businesses sometimes use the words interchangeably, but the contract should describe what the payment actually does rather than rely on the label.
For a recurring venue client, show each retainer draw as its own invoice line, list the event or work it covered, and carry the unused balance forward. For a one-event deposit, show the deposit as a prior payment against that event’s invoice and state the remaining balance.
Example: A venue collects a 3,000 dollar draw-down retainer from a corporate client that books several events each year. After a 1,200 dollar room rental and 300 dollars of coordination work, the invoice applies 1,500 dollars from the retainer and carries 1,500 dollars forward. The calculation is 3,000 minus 1,200 minus 300, leaving a 1,500 dollar balance.
FAQs
Frequently asked questions
Is a retainer fee refundable?
It depends on the agreement, applicable law, and the type of retainer. Unused draw-down amounts are often refundable, while an access or recurring retainer may be non-refundable once the reserved period begins. Put the earning and refund rules in writing and obtain local legal and accounting advice.
Is a retainer the same as a deposit?
Not necessarily. A retainer generally reserves availability or funds work over time. A deposit is usually a partial payment toward one project or event and is applied to that total. The written agreement and applicable law matter more than the label.
How do I invoice a recurring retainer?
Bill the agreed fixed amount on a regular schedule, such as the first of each month. A recurring invoice is well suited to this because it generates the same retainer charge automatically every period.
What is an effective hourly rate on a retainer?
Divide the retainer fee by the hours it covers. A 2,000 dollar retainer for up to 10 hours works out to 200 dollars per hour if the client uses the full allotment, and more per hour if they use less.
