How ExpenseBot Works for Agencies
Step 1: Write on the Receipt (The Magic)
Tag: ClientName
Before you snap a photo, write "Tag: Acme Corp" anywhere on the receipt. Our AI reads your handwriting and automatically attributes the expense to that client.
w/ Colin and Rob
Write "w/ Sarah, Mike, and Janet" to capture everyone at the meeting. Perfect for client entertainment, team lunches, or any group expense. Names appear in the expense notes automatically.
Snap and Done
Take the photo. That's it. The receipt is now tagged to the client, attendees are captured, and it's ready for export. No data entry, no end-of-month sorting.
Step 2: Four Layers of Attribution
What if someone forgets to write on the receipt? No problem. ExpenseBot has multiple fallback layers:
Step 3: Export by Client for Invoicing
When it's time to bill clients, filter by client name and export with one click. Attach to invoices or submit for internal allocation. Every expense is properly attributed, documented, and ready to go.
Going one step further: turn the same report into a Google Doc invoice in two clicks — auto-populated line items, country-aware tax suggestions, sent from your own Gmail. Built for agency passthrough billing.
What You Can Export:
- All expenses for one client — Perfect for invoice attachments
- Date range by client — Monthly, quarterly, or project-based
- Expense category breakdown — Travel, meals, entertainment, supplies
- Attendee reports — Who was at each client meeting
- QuickBooks export — With client codes already mapped
Sound Familiar?
😤 "Which client was this dinner for?"
End of month arrives. 47 restaurant receipts. No one remembers which client each meal was for. Hours spent in Slack asking "hey, do you remember that dinner on the 14th?"
😤 "The accountant needs everything sorted"
Before you can invoice clients, someone has to sort hundreds of receipts by client. It's the job everyone hates. And mistakes mean missed billable expenses.
😤 "We're definitely losing money"
Receipts get lost. Attribution gets forgotten. Billable expenses slip through the cracks. You know you're leaving money on the table but can't quantify how much.
✅ ExpenseBot solves all of this with one simple habit: write on the receipt.

Client Retainer Income + Billable Expenses, Per Client
ExpenseBot now captures client retainer payments and project deposits alongside the billable expenses your team already attributes by client. Stripe payout emails, ACH deposit alerts, milestone-payment confirmations from QuickBooks/FreshBooks, e-transfer receipts, wire-confirmation emails — all of it lands in Gmail in predictable forms, and ExpenseBot reads them the same way it reads a catering receipt or a venue invoice. The same Tag: ClientName annotation that attributes pass-through costs also attributes the incoming retainer to the right client.
That turns the Google Sheet into a real per-client P&L: retainer and project deposits on top, every billable cost (catering, venue, travel, influencer fees, production, media-monitoring subs) below. Filter by Tag: Nike and you see exactly what came in and what went out for that engagement this quarter — the kind of view that's useful when the client's CFO asks "where are we against the budget" and when your account team is deciding whether next quarter's scope expansion is worth taking.
Retainer-burn tracking, milestone billing, cost-plus markups, and fixed pass-through fees all work from the same data. At month-end, filter by client and export — the receipt images and deposit confirmations are linked row-by-row in your Drive, so the client's AP team gets itemized backup without manual assembly. Mid-size shop with finance review? See the CFO expense controls setup. Handing off to an outside accounting firm? The accountant workflow covers shared-access patterns.
Year-End Reports Built for Agencies
Once your expenses are tagged by client, ExpenseBot generates two agency-specific reports automatically — no setup required.
Agency Per-Client P&L

- Losing clients flagged in red — drop or renegotiate
- Profitable clients in green — replicate
- Passthrough warnings — catches when you paid ad spend (Meta, Google, LinkedIn) on a client's behalf and never rebilled them
- Preview in-app first, then generate a Google Sheet to share with your accountant
Agency Tax Preview (Schedule C / T2125)
Your full agency expense bundle mapped to the correct tax form lines — including the rule that client pass-through costs are not your advertising deduction. Hand it to your accountant at year-end, no sorting required.

Frequently Asked Questions
How does the 'Tag: ClientName' feature work?
Write 'Tag: ClientName' anywhere on a receipt before taking a photo. Our AI reads this annotation and automatically attributes the expense to that client.
Can I capture meeting attendees automatically?
Yes. Write 'w/ Colin and Rob' on the receipt and ExpenseBot automatically adds those names to the expense notes - perfect for client entertainment tracking.
What if I forget to write the client name?
No problem. You can tag at submission, AI will try to auto-classify based on patterns, or you can edit directly in the spreadsheet. Four layers of attribution.
Can I export expenses by client for invoicing?
Yes. Filter by client and export with one click. Perfect for attaching to client invoices or tracking internal allocations.
Does this work for multiple team members?
Absolutely. All team members can submit expenses with client tags. Everything rolls up into one view organized by client.
How do PR agencies handle pass-through client expenses?
Pass-through costs — catering for a press event, venue rental for a launch, courier fees, media-monitoring subscriptions charged to one client — get captured with a 'Tag: ClientName' annotation at submission. At the end of the retainer cycle, filter the Google Sheet by client, export, and attach to the invoice. The receipt images in your Drive serve as the backup documentation the client's AP team will ask for. No separate bookkeeping system required.
Can agencies tag expenses by campaign or project code?
Yes. Tag format supports compound labels — 'Tag: Nike-SummerLaunch' or 'Tag: Pepsi-SuperBowl2026' — so you can roll up expenses not just by client but by specific campaign for campaign-level P&L. Filter by tag in the sheet to see exactly what you spent on that launch: catering, travel, influencer fees, media buys. Useful for internal performance reviews and client reporting.
How do marketing agencies bill clients for expenses on retainer?
At the end of your billing cycle (monthly for most retainer contracts), filter the sheet by client, export as CSV or PDF, and attach to the client invoice along with receipt images. ExpenseBot stores every receipt in your Google Drive with a link from the spreadsheet row — the client's AP team gets itemized backup documentation without you having to assemble it manually. Works for straight reimbursement, cost-plus markup, and fixed pass-through fees.
Can I track billable expenses across multiple offices or team members?
Yes. Every team member submits via their own Google account (sign in with Google Workspace), and all client-tagged expenses roll into a single shared view. One account exec in New York and one in London can both submit dinner receipts tagged 'Client: Nike' and you see the unified view when invoicing. Works for any agency size — solo freelancer to 500-person network.
What does billable expense tracking mean for an agency?
Billable expenses are pass-through costs the agency incurs on a client's behalf and charges back to the client — venue fees, catering, travel for a client meeting, production costs, influencer fees, media buys. They're distinct from overhead (rent, staff salaries, internal software) which the retainer covers. Proper billable expense tracking means: (1) every pass-through cost is attributed to a specific client, (2) receipts are kept for backup documentation, (3) expenses can be filtered and exported for invoicing. ExpenseBot handles all three via the 'Tag: ClientName' annotation on every receipt.
Can agencies track client retainer income alongside billable expenses?
Yes. Retainer payments, project deposits, milestone-payment confirmations, and client wire-transfer notifications captured from Gmail auto-tag by client and sit in the same Google Sheet as billable expenses. The same Tag: ClientName annotation that attributes pass-through costs also attributes incoming retainer payments to the right client. The result is a real-time per-client P&L: retainer and project deposits on top, every billable cost (catering, venue, travel, influencer fees, production) below — useful for invoicing reconciliation, retainer-burn tracking, and quick answers when a client's CFO asks 'where are we against the engagement budget.' Works for marketing, PR, creative, and consulting agencies.
