Retainer agreement: getting paid before the work, without arguments

A retainer agreement is a contract under which a client pays a firm or freelancer on a recurring basis — for a block of hours, for a defined set of deliverables, or simply for availability. It is the standard arrangement for ongoing professional work, and it is popular for a good reason: it converts irregular project income into something a business can plan around.

It also produces a specific and predictable argument. The month the client uses four hours of a twenty-hour retainer, they want the sixteen carried over or refunded. The month they need forty, they want the extra absorbed. An agreement that does not answer both questions in advance will answer them badly under pressure.

The three kinds of retainer

• Pay for access: the client pays to have first call on your availability, whether or not work is requested. Common in law and crisis work, and the type most often misunderstood by clients as a prepayment.
• Pay for a block of hours or deliverables, drawn down each month. The commonest arrangement in agencies and consulting.
• Pay on account: money held against future invoices, drawn down as work is billed. Frequent in legal practice, and in many jurisdictions the funds must be held in a separate client account with strict rules.

What a retainer agreement has to say

• Which type it is, in plain words, since the three have completely different implications for unused value.
• What is included per period, expressed in hours or in named deliverables — not in ambitions.
• What happens to unused hours: expire at period end, roll over for a limited time, or refund. Say which.
• What happens when the work exceeds the retainer: prior approval above a threshold, an overage rate, or a stop.
• Payment timing — retainers are normally billed in advance, and saying so avoids the slide into arrears.
• Notice to terminate on both sides, and what happens to a partly used period.
• Review point for the rate, so the price is revisited on a date rather than in a difficult conversation.
• Scope boundaries, and the route for adding work outside them.

Unused hours are the clause that determines whether the arrangement survives. Expiry is defensible where the client is buying availability; it feels punitive where they are buying a block of work. Limited rollover — one period, no more — is the compromise that holds, because unlimited rollover eventually creates a balance nobody can staff.

Client money is a regulated category

Money paid on account of future work is not the firm’s money until it is billed. In regulated professions, particularly legal practice, it must be held in a designated client account with rules on transfers, records and reconciliation, and getting this wrong is a regulatory matter rather than a bookkeeping one. Even outside regulated practice the distinction is worth respecting: revenue recognised when the cash arrives rather than when the work is done flatters the accounts and misleads the person running the business.

Billing it without chasing it

A retainer is only predictable if the invoice goes out on the same day every period without anybody deciding to send it. Ettex Invoices handles the recurring billing and the payment reminders, Ettex Sheets tracks hours drawn against the balance so an overage is visible before it is a surprise, and the agreement itself belongs with the engagement letter in Ettex Docs, where the version in force is identifiable.

Plainly: none of this is legal or accounting advice, and client-account rules in particular are jurisdictional and strict. What software does here is the boring half — issuing the invoice on time and showing the balance — not deciding how the money may be held.
