Agency Expense Tracker for Client Accounts

You're billing clients every month but still can't tell which accounts are actually costing you money to service.

Track billable client expenses, campaign production costs, and mileage reimbursements across every active account your agency runs — all in one organized spreadsheet built for teams.

It's the last Friday of the month, and your account manager just dropped a Slack message: "Hey, did we ever get reimbursed for the venue shoot on the Hartley campaign?"

You open three different spreadsheets. Then a Google Form. Then your email. Then you give up and tell them you'll look into it Monday.

Monday comes. You're in back-to-back client calls. The Hartley expense gets buried. Again.

This is the invisible tax on running a growing agency — not the big budget mistakes, but the slow, grinding accumulation of untracked billable hours, production receipts your team logs inconsistently, mileage no one remembers to submit, and campaign costs that quietly eat into retainers you thought were profitable.

By the time you invoice, you're either undercharging because you can't prove the expenses, or you're overcharging and don't have the receipts to back it up. Neither is a good place to be when a client asks for a cost breakdown.

The Agency Field and Campaign Expense Tracker was built specifically for this problem.

**What This Spreadsheet Does**

This is a structured, team-ready expense tracking system designed for marketing agencies managing 8 to 20 active client accounts across retainers, project-based work, and field campaigns. It works in both Microsoft Excel and Google Sheets — no macros, no IT setup, no learning curve.

Here's how it works in practice:

**Client Account Ledger**
Every expense entry is tied to a specific client account from the moment it's logged. Whether it's a photo shoot, a media buy, a contractor invoice, or a field rep's gas mileage, it gets attributed to the right account automatically. No more sorting through a master dump of expenses at month-end trying to remember who that Uber receipt was for.

**Billable vs. Non-Billable Separation**
Not every agency cost gets passed to the client. This tracker separates billable expenses from internal overhead at the entry level, so your invoices only show what you agreed to charge — and your internal reporting shows what running that account is actually costing you.

**Campaign and Project Cost Tracking**
For agencies running production-heavy campaigns — shoots, activations, events, print runs — you can log and group costs by campaign or project within each account. See at a glance whether a campaign came in under or over its production budget before the invoice goes out.

**Mileage Reimbursement Log**
Field reps and account managers who drive for client work need a reliable place to log trips. This tracker includes a built-in mileage section with date, destination, purpose, and calculated reimbursement using your set rate — clean and ready for payroll or client billing.

**Weekly Team Submission Structure**
Designed for teams, not just solo operators. The layout supports a weekly cadence so account managers and field reps can log their expenses consistently rather than dumping everything on your desk at month-end. You set the structure. They fill it in.

**Per-Account Profitability View**
This is the section most agency owners say they've never had before. At the account level, you can see total revenue billed against total expenses logged — giving you a margin read on every client relationship. Find out which retainers are genuinely profitable and which ones are costing more to service than they're bringing in.

**Monthly and Quarterly Rollups**
The summary views aggregate everything across all accounts so you can see agency-wide expense trends, total mileage reimbursements owed, billable amounts pending, and month-over-month cost patterns — without building a single pivot table yourself.

**Who This Is Built For**

This tracker is the right fit if you're running a marketing, creative, or field services agency and any of these feel familiar:

- You have account managers submitting expenses in their own format — or not at all
- You've lost track of billable costs mid-campaign and had to eat the difference
- You've guessed at account profitability instead of knowing it
- You run a mix of retainers and project work and need both tracked the same way
- Your mileage reimbursements are handled through a separate, manual process
- Month-end invoicing takes longer than it should because expense data is scattered

If you're managing 8 to 20 active client accounts with a team logging expenses weekly, this was designed around your exact workflow.
