Every agency hits the point where the books outgrow the setup. The bookkeeper who was fine at $500K starts sending reports you can't act on, and tax season turns into a scramble.
The short answer: a marketing agency should hire an outsourced accountant who understands agency economics, not just bookkeeping. That means getting retainer and project revenue recognition right, separating media pass-through from real revenue, reporting profitability by client, and closing the books on a fixed schedule with someone senior available to explain what the numbers mean.
TL;DR
- Clean books are table stakes. The real test is whether the firm can tell you which clients and services make money.
- Ask about revenue recognition, gross vs. net revenue, client profitability, and 1099 handling in the first call. A generalist will struggle with at least two of them.
- Look for a fixed monthly close date, pricing tied to a defined scope, and access to CFO-level advice when you need it.
What should a marketing agency look for when hiring an outsourced accountant?
Use this as your checklist. A firm that genuinely serves agencies should answer every item with specifics, not "we can figure that out."
1. Retainer and project revenue recognition
Agencies bill retainers, deposits, milestones, and hourly work, often for the same client. Cash received is not revenue earned. A deposit collected in March for work delivered in April belongs in deferred revenue until the work is done. Your accountant should explain how they handle this without you prompting them. Our complete guide to agency revenue recognition walks through the mechanics.
2. Gross vs. net revenue and media pass-through
If you place media or buy production on behalf of clients, your top line can look far bigger than your business really is. Whether you report those costs gross or net depends on whether you act as principal or agent under ASC 606, and it changes every margin you calculate. An agency-focused accountant will also track agency gross income (revenue minus pass-through costs) as the base for your benchmarks. More in gross vs. net revenue for agencies.
3. Profitability by client and project
A company-wide P&L tells you whether the agency made money. It doesn't tell you which clients paid for that and which ones quietly lost money. The right firm assigns revenue, labor, and direct costs to clients and projects so you can see margin where decisions actually get made. See the agency profitability metrics to review monthly.
4. Utilization and capacity
Labor is your biggest cost, so billable utilization drives profit. Your accountant doesn't need to run your resourcing, but they should connect your time data to your financials and flag when utilization and margin drift apart. Background: agency utilization targets.
5. Contractor and 1099 handling
Most agencies lean on freelancers. That means W-9s collected up front, payments coded to the right client, worker classification reviewed, and 1099-NECs filed on time. For payments made in 2026, the 1099-NEC reporting threshold rises to $2,000 (from $600), and those forms are due February 1, 2027. A good firm builds this into the monthly process, not a January fire drill. See how to set up 1099 contractor payments and how to track freelancer costs by client.
6. Multi-state payroll
Remote teams create payroll registrations, withholding, and sometimes income tax filing obligations in every state where people work. Ask how the firm tracks where employees are and who registers you when someone moves. Details in multi-state payroll for remote agencies.
7. A fixed monthly close and reporting you can read
Ask for the close date in writing. Books that land six weeks after month-end are history, not management information. You should get a P&L with gross margin, a balance sheet, AR aging, and client profitability on a predictable schedule, plus a short read on what changed. Here's how to review agency financial reports each month.
8. Cash flow forecasting
Net-60 clients and twice-monthly payroll don't line up. A firm that understands agencies forecasts cash against your billing and collection patterns and tells you about a gap weeks before it hits. More on how net-60 clients hurt agency cash flow.
9. Access to CFO-level advice
Bookkeeping records the past. Owners need help with the future: pricing, hiring, owner compensation, and what happens if your biggest client leaves. Look for a firm where a CPA or fractional CFO is available when those questions come up, not just at tax time. Owner pay is a good test: ask how they set reasonable compensation for an S corp agency owner.
10. A tech stack that fits how you bill, and a clear pricing model
If you bill from Harvest, Toggl, Productive, Teamwork, or a similar tool, ask how that data reaches your books and your client profitability reports. Then ask how they price. Pricing tied to a clearly defined scope beats open-ended hourly billing that makes you hesitate before picking up the phone.
💡 Key Insight
The question isn't "are the books accurate?" It's "can my accountant tell me which clients to grow, reprice, or let go?" If the answer is no, you're paying for data entry.
Red flags when evaluating an agency accountant
- They record retainers as revenue the day the invoice goes out.
- Media spend and pass-through costs sit in revenue and cost of sales with no separate tracking.
- All contractors live in one expense line, so client margins are impossible.
- No committed close date, or reports regularly arrive more than a month late.
- They can't name the agency-specific problems they've solved for other agencies.
- Every question is billed by the hour.
Questions to ask in the first call
- How do you handle retainer deposits and project milestones in the monthly P&L?
- Do you report media and pass-through costs gross or net, and how do you decide?
- Can you show me a sample client profitability report?
- What day of the month will my books be closed?
- Who handles W-9s, 1099s, and multi-state payroll registrations?
- Who do I call when I'm deciding whether to hire or raise prices, and is that included?
- How will you pull in data from our time-tracking and project tools?

FAQ
Do marketing agencies need a specialized accountant?
Not on day one, but usually once you have retainers, pass-through media, or a contractor-heavy team. Those create revenue recognition and margin questions a generalist rarely handles well.
What's the difference between a bookkeeper and an outsourced accounting firm?
A bookkeeper records transactions and reconciles accounts. An outsourced accounting firm also closes the books on a schedule, produces management reporting, handles tax and compliance, and gives you advice on what the numbers mean.
When should an agency hire an outsourced accountant?
Before the books become a problem. Common triggers are passing roughly $500K in revenue, adding retainers or media buying, hiring in more than one state, or not knowing which clients are profitable.
How should an outsourced accountant be priced?
Look for pricing tied to a written scope: bookkeeping, close date, reporting, payroll and 1099 support, and how much advisory time is included. Compare quotes on scope, not headline price.
What reports should an agency get every month?
At minimum: a P&L with gross margin, a balance sheet, AR aging, a cash forecast, and profitability by client. Ideally with a short summary of what changed and what to do about it.
Should media spend be counted as agency revenue?
It depends on whether you act as principal or agent for that spend under ASC 606. Either way, measure your margins on agency gross income so pass-through costs don't distort them.
