Why Is Bookkeeping for Marketing Agencies Different and What Should You Prioritize?

When it comes to financial management, marketing agencies are a different beast. Unlike product-based businesses that sell tangible goods or SaaS companies that rely on predictable subscription revenue, agencies operate in a dynamic, fast-paced environment where revenue, expenses, and team structures can shift month to month. If you’re not keeping your books in order, it’s easy to lose track of what’s profitable, and what’s not.

Contents

    In this post, we’ll break down why bookkeeping for marketing agencies is unique, what financial areas deserve your attention, and how to set your books up for clarity, compliance, and long-term success.

    Why Bookkeeping for Marketing Agencies Is Different

    Marketing agencies don’t operate like traditional businesses. Most agencies juggle a mix of recurring retainers, one-off projects, and ad hoc consulting work—each with different scopes, billing cycles, and delivery timelines. On top of that, it’s common for agencies to rely on external subcontractors like copywriters, designers, or developers to fulfill parts of a project.

    This layered model means cash doesn’t always flow predictably. You might sign a $30,000 contract, but if payments are spread over milestones or delayed by client approval, your bank balance could look very different from your actual revenue earned. Agencies also tend to run lean, meaning margins are tight and accurate tracking of cash flow and profitability is absolutely essential.

    When you have multiple clients, each with their own timeline, budget, and deliverables, the bookkeeping challenge builds up quickly. That’s why agency owners need a financial system tailored to their specific workflows, not a one-size-fits-all approach.

    Revenue Tracking for Retainers and Projects

    Not all revenue is created—or recognized—the same way. Most agencies work with a combination of monthly retainers and project-based contracts, and it’s important to track both accurately.

    • Retainers provide recurring, predictable income. These are often billed monthly and tied to ongoing services such as social media management, SEO, or content creation. With retainers, revenue is typically recognized evenly each month, assuming services are delivered consistently.
    • Projects, on the other hand, are usually one-time or milestone-based and may stretch across several weeks or months. Recognizing revenue too early (e.g., when the invoice is sent) can misrepresent your actual earnings if the work isn’t completed yet.

    For accurate books, tie revenue recognition to when the work is performed or delivered, not just when you send the invoice. Tracking income by client, service line, or campaign can also help you understand which projects are most profitable and which ones might be draining resources.

    Managing Freelancers and 1099s

    It’s no secret that most agencies rely on freelancers and contractors to get the job done. Whether it’s bringing on a video editor for one campaign or a web developer for a 3-month project, keeping tabs on who’s doing what—and how much they’re being paid—is essential for financial clarity and IRS compliance.

    Here’s what you need to know:

    • Anyone you pay $600 or more in a calendar year for services (and who is not an incorporated business) likely requires a 1099-NEC to be filed.
    • Contractors should be tracked separately from employees. That means separate GL accounts, clearly categorized payments, and proper W-9s collected upfront.
    • Misclassifying a freelancer as a W-2 employee (or vice versa) can trigger penalties during a tax audit, so accuracy here matters.

    Using bookkeeping software that allows you to tag and categorize contractor payments by project can make reporting and tax prep much smoother down the line.

    Which Expenses Matter for Tax Time

    Tax time can sneak up fast, and if your expenses aren’t categorized properly, you could miss out on valuable deductions. Fortunately, most marketing agency expenses are tax-deductible, as long as they’re documented and organized correctly.

    Here are some common deductible expenses to track:

    • Contractor payments: Designers, copywriters, strategists, editors, and developers.
    • Software subscriptions: Think Adobe Creative Cloud, project management tools (Asana, Trello), email platforms (Mailchimp), CRMs, and analytics tools.
    • Marketing and advertising: Paid social campaigns, Google Ads, influencer partnerships.
    • Professional services: Legal, bookkeeping, consulting, and accounting fees.
    • Client-related travel and meals: As long as it’s business-related and appropriately documented.

    The IRS is very clear: expenses must be “ordinary and necessary” to your business. Keep digital receipts, write short notes on business purposes, and work with your bookkeeper to ensure your chart of accounts captures each category cleanly.

    For more guidance, visit the IRS Deducting Business Expenses page.

    Best Practices for Your Chart of Accounts

    Your chart of accounts (COA) is the foundation of your bookkeeping. When it’s tailored to how your agency actually operates, financial reports become cleaner, clearer, and far more actionable.

    For agencies, a smart chart of accounts might include:

    • Income
      • Retainer Revenue
      • Project-Based Revenue
      • Consulting Revenue

    • Cost of Sales (Direct Costs)
      • Contractor Payments
      • Ad Spend for Clients
      • Production Tools (e.g., design software specific to deliverables)

    • Operating Expenses
      • General software (e.g., GSuite, Slack)
      • Office rent or remote team stipends
      • Marketing your agency

    • Owner Compensation
      • Payroll for founders
      • Owner draws or distributions

    A well-structured COA removes guesswork, avoids lumping unrelated expenses together, and gives you the ability to run reports that actually tell a story.

    What to Review Monthly or Quarterly

    Keeping your books up to date isn’t just about avoiding tax season stress, it’s about staying on top of your business. At minimum, every agency should review the following each month or quarter:

    • Review accounts receivable: Who still owes you money? Are there aging invoices?
    • Reconcile contractor payments: Are all 1099s on track for year-end filing?
    • Run a profit and loss report by client or project: Where are you making the most margin?
    • Check upcoming software renewals: Are you still using everything you're paying for?

    It’s easy to let these reviews slip during busy client months, but doing them regularly keeps your finances accurate, your taxes clean, and your operations streamlined.

    Frequently
    asked
    questions

    Why is bookkeeping for marketing agencies different from other businesses?

    Because agencies manage a blend of project and retainer income, subcontractors, and tight cash flows, they need more nuanced revenue tracking and expense categorization than product-based businesses.

    What should agencies prioritize when managing their bookkeeping?

    Accurate revenue recognition, clean contractor tracking, expense categorization, and a chart of accounts tailored to how your agency earns and spends money.

    How can agencies keep their bookkeeping organized throughout the year?

    By reviewing reports monthly, staying on top of invoicing and payables, and working with a bookkeeper who understands the specific needs of agencies.

    Frequently
    asked
    questions

    What’s the difference between a debit and a credit in business accounting?

    In accounting, a debit is an entry that increases assets or expenses, while a credit increases liabilities, equity, or revenue. Every transaction affects at least two accounts — one with a debit and one with a credit — to keep your books balanced.

    Do debits always mean money coming in and credits mean money going out?

    Not exactly. It depends on the type of account. For example, debiting an expense means you're spending money, but debiting an asset like cash means you're receiving money. That’s why understanding account types is essential.

    Why do I need to understand debits and credits if I have a bookkeeper?

    Even if someone else handles your books, knowing the basics helps you read financial reports, ask better questions, and make smarter business decisions. It also makes you a stronger communicator with your finance team or investors.

    What’s a T-account, and how does it help?

    A T-account is a simple visual tool used in accounting to show how a transaction affects two accounts. Debits go on the left, credits on the right. It’s a great way to visualize the flow of money and keep things balanced.

    How can I tell if my financial reports are accurate?

    Look for common red flags: negative balances, uncategorized transactions, or mismatched totals. If you’re unsure, it’s worth having a professional review your books to make sure everything aligns before big decisions or tax time.

    questions

    Why does Josh describe accountants as “storytellers”?

    Josh believes the value of accounting lies in interpretation, not calculation. Tools such as Exce; already do the math—what founders need is someone to explain what the numbers mean and how they impact strategic decisions. That’s why Function focuses on turning data into stories that help drive business forward.

    How is Function designed to scale without losing personal service?

    Josh built Function with intention: hire thoughtfully, delegate wisely, and embed values into every part of the team. Delegation wasn’t easy, but it allowed Function to grow without becoming impersonal. The goal is to deliver high-touch service at scale—and keep founders from burning out trying to do everything themselves.

    What problem is Function solving for startup founders?

    Function addresses a common frustration: most founders are left to interpret their own financial data. Instead of delivering static reports, Function turns numbers into clear, actionable insights that guide decision-making—pushing information to founders rather than making them dig for it.

    How do I get started with Function?

    Getting started with Function is simple. Founders can visit onefunction.com to book an intro call, learn more about the services offered, and see if the team is the right fit. The onboarding process is built to be smooth and tailored—starting with a conversation about your current financial setup, goals, and the support you need to grow confidently.

    What does Function mean by being “the adult in the room”?

    In today’s tougher funding environment, investors expect startups to be more financially disciplined. Function steps in with experienced, unbiased financial guidance to help founders stay focused, meet their targets, and present investor-ready financials.

    Frequently
    asked
    questions

    I’m not making money yet—do I really need bookkeeping?

    Yes. Even if you’re pre-revenue, you’re likely spending money—whether on software, legal fees, marketing, or contractors. Bookkeeping helps you track those costs, stay organized for taxes, and prepare for investor conversations before they happen.

    Can’t I just wait and figure it out later?

    Waiting often creates more problems than it solves. Messy or missing records can lead to costly cleanup, missed tax deductions, or even lost funding opportunities. Getting your books in order early means less stress and smarter decisions from day one.

    What kind of bookkeeping support does a startup actually need?

    It depends on your stage and growth plans. In the beginning, you may just need basic transaction tracking. As you scale, you’ll need deeper insights, reporting, and forecasting. Function grows with you—from clean books to CFO-level strategy.

    How does Function make bookkeeping easier for founders?

    We handle the financial heavy lifting, so you don’t have to. From tracking expenses to CFO strategy insights, Function gives you clean, up-to-date books and actionable information—so you can focus on building, not balancing spreadsheets.

    Frequently

    questions

    What does a fractional CFO for business startups actually do during fundraising?

    A fractional CFO helps build your financial model, prepare forecasts, clean up your reports, align your pitch with your numbers, and get all the due diligence materials ready. They also help you answer tough investor questions with confidence.

    When should a startup hire a fractional CFO before fundraising?

    Ideally, at least 2–3 months before you plan to start pitching. This gives enough time to get your books in order, build your model, and craft a deck that reflects your financial story.

    How does a fractional CFO improve a startup’s chances with investors?

    Investors fund confidence. A fractional CFO ensures your financials are credible, consistent, and well-prepared, reducing red flags and speeding up diligence. This can significantly improve your chances of getting a “yes.”

    questions

    Who needs to follow Form 5472 instructions and file the form?

    Any U.S. corporation with at least 25% foreign ownership, and any foreign-owned single-member LLC with U.S. operations, is likely required to file Form 5472, especially if they engage in reportable transactions with foreign entities.

    What kind of transactions require disclosure on Form 5472?

    Common reportable transactions include loans, payments for services, capital contributions, reimbursements, and management fees between a U.S. company and a foreign-related party.

    What happens if I don’t file Form 5472 correctly or on time?

    You could face a minimum of $25,000 penalty per year. If you fail to respond to IRS follow-ups, the penalties may increase. Non-filing can also create issues during fundraising, audits, or acquisitions.
