Your AI AP Colleague
for Media Agencies

Every month, your AP team spends the first week downloading Mediaocean invoices one by one, chasing approvers who haven't replied, and rebuilding the accrual file from scratch. Stamp ends that.

Sound familiar?
01
A vendor emails a PDF invoice. It lands in three inboxes. Nobody knows who's handling it — or whether it's already been processed.
StampCaptures it on arrival, deduplicates, and routes it. No one has to touch it.
02
The invoice from DSP Partners says $21,750. The insertion order was for $18,000. Do you pay it? Push back? And who even makes that call?
StampFlags the mismatch, surfaces the IO, and routes it for a decision — with full context.
03
You asked the campaign manager to approve an invoice six days ago. They haven't replied. You're going to have to chase them. Again.
StampSends reminders on your schedule, with full invoice context, until they reply.
04
Your CFO needs the accrual file by Monday morning. It's Friday. You're building it from scratch, pulling numbers from three different spreadsheets.
StampDelivers the completed accrual file to your inbox on the 1st — every month, automatically.

Give an instruction.
Stamp handles the rest.

Stop managing AP. Start delegating it.

The Media Agency AP Problem

The Manual Download Loop

Log in. Find the campaign. Open the buy. Download the invoice. Repeat — for every invoice, every month.

02

Gross vs. Net Confusion

The same "amount due" can mean gross or net depending on the vendor. Your team has to figure out which — every time.

03

The Accrual File Is Always Behind

Built manually every month from multiple spreadsheets. When invoices are late or missing, the numbers are wrong — and client billing depends on them.

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.

Gross vs. Net Intelligence

Is this invoice gross or net? You shouldn't have to guess.

Mediaocean's "amount due" field is ambiguous — the same number can mean two completely different things depending on the vendor. Your team shouldn't be making calls to find out. Stamp identifies which convention each vendor uses and tells you exactly what to pay.

Approval Automation

Approvers get one email. They reply. You're done chasing.

When an invoice lands, Stamp sends the right person one email with everything they need to decide — vendor, amount, campaign, budget vs. actual, IO match. They reply from their regular inbox. The invoice updates automatically. No portal login, no forwarding chains, no Slack follow-ups.

Accrual Automation

Your CFO wants the accrual file by Monday. Stamp already sent it.

Every month starts with a media plan — what you committed to spend per client, per campaign, per vendor. As invoices arrive, Stamp matches them to plan lines and keeps the accrual file current. You never build it from scratch again.

AI Background Work

The work that happens between invoices? Stamp does it instead.

Every invoice that arrives triggers a chain of manual work: check the IO, verify the amount, match it to the bank, follow up with the vendor, onboard the new contact. Stamp runs it all in the background — automatically, for every invoice, without being asked.
