How to track project profitability in a PPC agency?

Key takeaways

• Project profitability is your revenue minus all direct costs, including team time, freelancers, software, and a fair share of ad spend management. It's the only way to know which clients are truly profitable.
• Accurate time tracking is non-negotiable. You must know how many hours your team spends on each client's campaigns, reporting, and communication to calculate your true labour cost.
• Include all direct costs in your calculation. Beyond salaries, factor in freelance support, specific software subscriptions, and a portion of ad spend management fees to see the real picture.
• Use the data to make better decisions. Knowing your project margins lets you price retainers correctly, identify scope creep, and decide which clients to grow, fix, or exit.
• Simple tools can get you started. You don't need complex software. A combination of time tracking apps, spreadsheets, and your accounting software can build an effective system.

Many PPC agencies think they're profitable because their bank balance looks healthy at month-end. They see the retainer fees coming in and assume all is well. But this is a dangerous illusion. True PPC agency project profitability tracking goes much deeper.

It tells you exactly how much money you make on each client after paying for everything it takes to service them. Without this insight, you're flying blind. You might be losing money on your biggest client or underpricing your services by thousands.

This guide breaks down exactly how to track project profitability in a PPC agency. We'll cover what costs to include, how to track time accurately, and which metrics actually matter. You'll learn how to move from guesswork to data-driven decisions that protect your margins.

What is project profitability for a PPC agency?

Project profitability is the actual profit you make from a single client or campaign after accounting for all the direct costs of delivering that work. For a PPC agency, it's not just your retainer fee minus your team's salaries. It's a precise calculation that includes time, software, freelancers, and the cost of managing ad spend.

Think of it like this. You charge a client £3,000 per month. Your PPC executive spends 15 hours a week on their account. Your account manager spends 5 hours. You use a specific bid management tool that costs £150/month for their account. A freelance designer did £500 of ad creative work.

Your project profitability is what's left after you add up all those costs. If the total cost is £2,800, your profit is only £200. That's a 6.7% margin. Most agencies aim for a project margin of at least 30-40%. This kind of project margin analysis reveals the truth.

Without tracking this, you only see the top-line revenue. You miss the slow drain of unbilled hours, rising software costs, and inefficient processes. PPC agency project profitability tracking is your financial microscope.

Why do most PPC agencies get project tracking wrong?

Most agencies fail at project tracking because they only look at revenue and overall agency profit. They don't drill down to the client level. Common mistakes include not tracking time properly, forgetting indirect costs, and treating all revenue as equal profit.

A major error is ignoring the cost of ad spend management. If you're managing £50,000 in monthly ad spend for a client, that requires more oversight, reporting, and optimisation than a £5,000 budget. That extra work has a cost. Failing to account for it in your project costing for service businesses means you undercharge for complex clients.

Another mistake is using average costs instead of real ones. Saying "our average cost per hour is £50" is useless if your senior strategist (costing £80/hour) is doing work a junior (costing £35/hour) could handle. You need real data.

Finally, many agencies don't have a system. They try to do it mentally or with messy spreadsheets once a quarter. Profitability tracking must be ongoing and systematic to be useful. Specialist accountants for PPC agencies often find this is the first system they help clients build.

What costs should you include in your PPC project calculation?

You must include every cost that is directly tied to delivering work for that specific client. This is the core of accurate project costing for service businesses. Missing costs inflate your perceived profit and lead to bad decisions.

First, include team labour cost. This is the biggest cost for most agencies. Calculate it using the actual hourly cost of each employee (salary + employer taxes + benefits) multiplied by the hours they spend on the project. Accurate time tracking for profitability is essential here.

Second, include freelancer or contractor costs. Any specialist you bring in for that client—a copywriter, designer, or analytics expert—is a direct project cost. Their invoice should be allocated to the specific client project.

Third, include direct software costs. Does this client require a specific reporting tool, bid management platform, or competitor analysis software? If a subscription is used primarily for one client, allocate its full cost. If it's shared, allocate a fair portion.

Fourth, include a cost for ad spend management. This is unique to PPC. Managing larger, more complex ad budgets requires more work. Allocate a portion of your strategy and management team's time to this, or use a small percentage of the managed ad spend as a proxy for the effort involved.

Do not include general overheads like office rent, utilities, or general accounting software in the project cost. These are indirect costs covered by your overall agency gross profit. The goal is to find the direct profit for each project.

How do you track time accurately for PPC work?

You need a mandatory, easy-to-use system where every team member logs time against specific client projects and tasks. The data must be detailed (showing tasks like "campaign build", "weekly report", "client call") and reviewed regularly to ensure accuracy and completeness.

Choose a time tracking for profitability tool that integrates with your other systems. Tools like Harvest, Clockify, or Toggl Track are popular. They allow you to create projects for each client and tasks within them. The key is making it a non-negotiable part of the workflow.

Train your team on why this matters. Explain that it's not about micromanagement, but about understanding client profitability so the agency can price fairly, pay them well, and stay in business. When people understand the "why", compliance improves.

Set clear expectations. All time must be logged, including internal meetings about the client, email communication, and report writing. Even 15-minute check-ins add up. Review time logs weekly with team leads to catch missing entries and discuss why some tasks took longer than estimated.

This data is gold. It shows you which clients are time vampires. It reveals if your reporting process is inefficient. It provides the raw numbers for your PPC agency project profitability tracking. Without accurate time data, any profit calculation is just a guess.

What metrics and formulas should you use?

Focus on a few key metrics: Project Profit, Project Margin %, and Cost Per Hour. Calculate Project Profit as: Project Revenue - Total Direct Project Costs. Calculate Project Margin % as: (Project Profit / Project Revenue) x 100.

Let's use a real example. Your client pays a £4,000 monthly retainer. Your direct costs are: Team labour (£2,200), freelance designer (£300), client-specific software (£200). Your total direct cost is £2,700.

Project Profit = £4,000 - £2,700 = £1,300.
Project Margin % = (£1,300 / £4,000) x 100 = 32.5%.

This is a healthy margin. Now, track this every month. Is the margin consistent? Is it trending down because costs are creeping up? This is the power of project margin analysis tools and processes.

Also, calculate your actual cost per hour. Divide the total direct labour cost for the project by the total hours logged. Compare this to your "target" or "billable" rate. If your target rate is £75/hour but your actual cost is £90/hour, you're losing money on every hour worked for that client.

These metrics, tracked over time, give you an undeniable fact base for conversations about price increases, scope reduction, or process improvement.

What tools can help with PPC project profitability tracking?

You don't need one magical, expensive platform. A connected stack of simple tools works brilliantly. Start with a dedicated time tracker, use a spreadsheet or basic project accounting module, and ensure your data flows together.

For time tracking, use apps like Harvest, Clockify, or Toggl Track. They are affordable and user-friendly. They allow you to export data or connect to other tools via Zapier. This solves the time tracking for profitability challenge.

For the calculation and reporting, you can start with a well-designed spreadsheet (Google Sheets or Excel). Create a tab for each client. Link it to your exported time data and manually add other direct costs. This can be a powerful, free project margin analysis tool.

As you grow, consider tools with built-in project accounting. Xero with Projects, or QuickBooks Online, allow you to assign expenses and tracked time to specific jobs and see profitability reports. Some agency-specific platforms like FunctionFox or Productive combine project management with budgeting and profitability.

The best tool is the one your team will actually use. Complexity is the enemy of adoption. Start simple, get the process right, then upgrade your tech stack. For a deeper look at how technology is reshaping agency operations, our AI impact report for agencies explores these trends.

How do you use profitability data to make better decisions?

You use the data to inform three key areas: pricing, client management, and operational efficiency. The numbers tell you what to change, not just that something is wrong.

For pricing, compare your project margin to your agency target (e.g., 40%). If a client is at 15%, you know their next retainer proposal needs a significant price increase to reflect the true cost of service. The data justifies the increase.

For client management, identify scope creep. If monthly hours for a fixed-fee client are steadily rising, your margin is being squeezed. Use the time tracking data to have a factual conversation with the client about adjusting scope or price.

For operations, find inefficient processes. If "monthly reporting" takes 10 hours for one client but 4 for another with similar spend, investigate. Standardise the efficient process. This improves margins across the board.

You can also segment clients. Create a simple grid: High Profit/Low Maintenance (Stars), High Profit/High Maintenance (Cash Cows), Low Profit/Low Maintenance (Question Marks), Low Profit/High Maintenance (Dogs). Your strategy for each segment is different. This is advanced PPC agency project profitability tracking in action.

How often should you review project profitability?

Review project profitability at least monthly. This aligns with your typical billing cycle and gives you timely data to act on. A quarterly review is too slow—problems can drain your profit for three months before you spot them.

Make it part of your monthly management routine. After monthly invoices are sent and costs are logged, run your profitability reports. Schedule a 30-minute meeting with your account leads to review the numbers for their clients.

Look for trends, not just point-in-time figures. Is Client A's margin dropping 5% each month? That's a red flag. Investigate immediately—is it more client calls, more complex optimisation, or an internal training issue?

This regular review turns financial data into a management tool. It moves project costing for service businesses from an accounting task to a commercial driver. For help establishing this rhythm, many agencies use our free financial planning template to structure their reviews.
