Agencies & consultanciesAccounting for Consultants: Retainers, Deferred Revenue, and Paying Yourself

On January 3rd, a $30,000 retainer lands in your business account. You look at the balance. You look at the balance again. You start browsing standing desks.

Then March arrives, the retainer work is still going, no new money has come in, and you realize January's cash was for January, February and March. The standing desk is very nice, though.

This is the most common trap in accounting for consultants, and it has a tidy fix. Here's how to record retainers, what deferred revenue means, and how to pay yourself without turning your books into a mystery novel.

Why a retainer isn't income yet

When a client pays before you do the work, you owe them that work. In accounting terms, the prepayment is deferred revenue: money received for services you haven't delivered yet. It sits on the balance sheet as a liability until you earn it.

As you deliver, you move the earned portion from deferred revenue to income. That's the accrual approach (recording income when it's earned and expenses when they're incurred, not when cash moves). It gives you a P&L that reflects what you actually did each month.

Plenty of solo consultants keep their books on a cash basis, especially early on, and that can be fine for simple setups. But once retainers get large or span quarters, cash-basis books make some months look spectacular and others look like a slump, even when the work was steady. Which basis you file taxes on is a question for your CPA. You can still run accrual books for management purposes either way.

If the idea of spreading a payment across months feels abstract, our explainer on accruals and prepaids, explained with a coffee subscription makes it very concrete.

How to record a deferred revenue retainer

Say you sign a three-month strategy engagement for $30,000, paid upfront on January 3rd, with work spread evenly.

By March 31, deferred revenue is back to zero and you've recognized $10,000 of income each month. Your January P&L shows $10,000, not $30,000, which is exactly the point.

If work isn't spread evenly (a heavy discovery phase, then lighter follow-up), recognize income based on milestones or hours delivered. Pick a method that matches the contract and use it consistently.

Monthly retainers and the other flavors

Not every retainer is a big prepayment. Common setups:

1. Monthly retainer billed at the start of the month for that month's work. Usually recognized as income in that same month, with little deferral needed.
2. Prepaid block of hours. Deferred until hours are used. Track hours remaining and recognize as you go.
3. Evergreen or replenishing retainer. The client keeps a balance with you that you draw down. Treat the unused balance as deferred revenue.
4. Retainer as a deposit against a final invoice. Deferred until the project is billed, then applied.

Bookkeeping for consultants mostly comes down to knowing which of these you have, writing it down, and setting up the books to match.

Paying yourself without confusing the books

Now the fun part: getting money out of the business and into your life.

How you pay yourself depends on how your business is set up. Sole proprietors and most LLC owners generally take owner's draws, which reduce equity and aren't expenses. Owners of S corporations generally run themselves through payroll and may also take distributions. What counts as a reasonable salary, and how your entity is taxed, is a call your CPA makes. Our article on owner's draw vs salary covers how each one shows up in the books.

A few habits that keep things clean:

• Pay yourself on a schedule, like the 1st and 15th, instead of whenever the balance looks high.
• Base the amount on earned income (your accrual P&L), not on cash that's still owed back as work.
• Keep a separate savings account for taxes. Ask your CPA how much to set aside.
• Never pay personal bills straight from the business account. It's like using your work email for group chats: technically possible, eventually confusing.

A simple monthly routine for consultants

Here's what a month of clean books looks like:

1. Reconcile your business checking and credit card accounts.
2. Record any new retainers to deferred revenue.
3. Move earned portions of each retainer to income, based on the contract.
4. Record billable expenses and make sure they're invoiced to clients.
5. Record your own pay as a draw or payroll, matching your entity.
6. Review the deferred revenue balance. It should equal the work you still owe clients.

That sixth step is a surprisingly good gut check. If deferred revenue says you owe $45,000 of work and your calendar says otherwise, something needs fixing.

When you grow into a firm

Once you add associates or subcontractors, the questions shift from "how much did I make?" to "which clients make us money?" Our guide to measuring profit by client in agency accounting picks up from there, including how to price team time. And if you want a team to handle retainers, close and reporting for a growing practice, our agency and consultancy accounting service is built for exactly that.
