The Media Agency AP Problem

Three Parties. Two Invoice Streams. One Overwhelming Manual Process.

Media agencies sit at the center of a complex billing triangle — and AP teams are stuck doing all the legwork by hand.

🏢
Client
(Brand / Advertiser)
Approves budgets, expects invoices at gross billing
Bills at gross
→
🏦
Your Agency
(AP Team in the middle)
Reconciles gross vs. net, matches invoices to plans, builds accrual files
All the complexity lives here
Invoices at net (sometimes gross)
←
📡
Ad Networks
(TV, Digital, OOH, Print)
Invoice via email PDF or inside Mediaocean — no consistent format

Invoices arrive from two completely separate places

📧
Email Invoices

PDF attachments from ad networks, forwarded from vendors, scattered across your inbox. Easy to miss, impossible to track.

+
🖥️
Mediaocean Invoices

Trapped inside the platform. To get them out, you log in, navigate to each buy, and download one invoice at a time. There is no bulk export.

Most painful part
01

The Manual Download Loop

Your AP team logs into Mediaocean, finds each campaign, opens each buy, locates the invoice, and downloads it. One. By. One. For dozens or hundreds of invoices every month.

02

Gross vs. Net Confusion

Mediaocean's "amount due" field can show either gross or net depending on the vendor setup. Without knowing which convention applies, your team doesn't know what to actually pay — or bill.

03

The Accrual File Is Always Behind

Someone manually updates an Excel file tracking plan vs. actual spend per client, per campaign. When invoices are late or in multiple formats, the accrual file is wrong — and client billing depends on it.

Three Steps to an AP Team That Runs Itself

You set the rules once. Stamp handles everything that follows.

🖥️
Connect
Link Your AP Inbox
Stamp connects to Gmail or Outlook and pulls directly from Mediaocean. Your full invoice universe — email attachments and platform invoices alike — flows into one place automatically.
💬
⚙️
Instruct
Tell Stamp What You Need
Ask a question or give a standing instruction in plain English. "Route this for approval and remind every 2 days." "Flag anything without an IO." "Create my accrual file on the 1st." Stamp confirms and runs it.
✅
📬
Results
Delivered Without Logging In
Approvals route. Reminders go out. Accrual files land in your inbox. Vendors get onboarded. You get answers — via Slack, email, or wherever you work — without touching a portal.

Built for media agency AP teams who are done spending their week managing a process a machine should handle.

"Our AP team spends the first week of every month just downloading invoices from Mediaocean one by one and trying to figure out if the amounts are gross or net. It's manual, error-prone, and completely unsustainable at our billing volume."

Everything Your Media Agency AP Team Needs — Automated

Mediaocean Integration

Stop Downloading Invoices One by One

Stamp connects directly to Mediaocean and pulls every invoice automatically — no manual login, no navigating buy by buy, no individual downloads. What used to take days now takes seconds.

AP teams at mid-size agencies report spending 3–5 days per month just extracting Mediaocean invoices manually. Stamp eliminates that entirely.

Gross vs. Net Intelligence

Always Know Exactly What You Owe

Mediaocean's "amount due" field is ambiguous — some vendors bill gross, some bill net. Stamp automatically identifies which convention each vendor uses, applies the correct agency commission rate, and tells you the exact amount to pay.

No more calling vendors to clarify. No more spreadsheet formulas. No more paying the wrong amount and chasing corrections for weeks.

Approval Automation

Approvers Reply to Email. No Portal Login.

When an invoice needs approval, Stamp emails the right person with full context — vendor, amount, campaign, budget vs. actual, and the Mediaocean buy it maps to. They reply with their decision. The invoice status updates automatically.

Set a reminder cadence — "remind every 2 days until they reply" — and Stamp runs it indefinitely, until every invoice is resolved. Your AP team stops chasing approvals and starts reviewing results.

Accrual Automation

Your Accrual File Updates Itself

Every month starts with a media plan — what you committed to spend per client, per campaign, per vendor. As invoices arrive (from email or Mediaocean), Stamp matches them to plan lines and updates your accrual file automatically.

Tell Stamp to deliver it on the 1st of every month, and it will — forever. No building, no formatting, no manual pulls. Just an accurate file in your inbox when you need it.

AI Background Work

Stamp Works in the Background — All the Time

Beyond what you ask for, Stamp runs the tasks your AP team handles manually today: cross-checking every invoice against signed insertion orders, matching cleared bank payments to approved invoices, drafting professional responses to vendor payment status inquiries, and automatically requesting W-9s and insurance certificates from new vendors.

Set the rules once. Stamp handles every invoice that follows — forever.

Client Visibility

Your Clients Are Billing on This Data

See every client's committed vs. invoiced spend across all campaigns and vendors, at a glance. Stamp rolls up invoices per client so you always know where each client stands against their media plan.

Over-budget campaigns get flagged the moment an invoice arrives — not discovered at month-end when it's too late to course-correct. Ask Stamp for a client summary anytime — you'll get it in seconds.

⚡

No New Platform to Learn

Stamp works on top of the tools your AP team already uses — Mediaocean, Gmail, Outlook, Excel, and Slack. No new system, no retraining, no change management. Just the same work, handled automatically.

🔒

Secure and Private

Your invoice data and client financial information are processed securely and never used to train third-party models. Only your team has access to your data.
