How does an agentic marketplace handle deal disputes between buyer and publisher agents?

An agentic marketplace handles deal disputes between buyer and publisher agents through a programmatic resolution process that begins with the signed deal record as the authoritative reference for what was committed. The buying agent raises a discrepancy flag, both agents query the deal record, the marketplace compares delivery data against committed terms, and either closes the flag if data matches or escalates to defined resolution steps if it does not. The entire process should run without human intervention for routine discrepancies.

An agentic marketplace handles deal disputes between buyer and publisher agents by providing a programmatic resolution workflow anchored to the signed deal record. When a buying agent detects that delivered inventory diverges from the terms it committed to, it raises a compliance flag against the deal record. The marketplace triggers a resolution sequence: both agents query the deal record, delivery data is compared against committed terms, and the flag is resolved or escalated based on what the comparison shows.

This is how disputes should work in a mature agentic marketplace. The key requirement, and the one that distinguishes mature from immature infrastructure, is the deal record itself.

At a glance

Deal dispute: A disagreement between the buying agent and publishing agent about whether delivery matched the committed deal terms - price, volume, publisher environment, brand safety, or completion rate.

Dispute terms: The contractual provisions in the deal record specifying how discrepancies are identified, evidenced, and remedied - written at the time of commitment, not retrospectively.

Delivery discrepancy: A difference between what the deal record shows was committed and what delivery data shows was actually delivered; the trigger for a dispute process.

Bilateral deal record: A deal record held by the neutral marketplace and queryable by both sides — the reference point that both agents use to evidence a dispute.

Why does dispute resolution start with the deal record?

The deal record is the authoritative reference for what was committed. If both the buyer agent and the publisher agent accept the same deal record as their shared reference, a dispute about whether delivery matched commitments is resolvable by data. If there is no shared record, the dispute starts with competing accounts of what was agreed, which is a different and harder problem to resolve.

This is why bilateral deal record governance is the precondition for automated dispute resolution. An agentic marketplace that does not provide bilateral deal records cannot provide programmatic dispute resolution either. It can provide a communications channel for agents to exchange dispute claims, but those claims will rely on each side's own records and will require human adjudication.

What does a typical dispute resolution sequence look like?

In an agentic marketplace with mature governance, the sequence runs as follows. During delivery, the buying agent periodically queries the deal record and compares it against delivery reports from the ad server and verification technology. When a parameter deviation exceeds a defined threshold, the agent raises a compliance flag against the deal record.

The marketplace notifies the publisher agent of the flag. The publisher agent queries its own delivery data and the deal record. If the publisher agent's delivery data matches the committed terms, it responds with that data and the flag is reviewed. If the data supports the buyer agent's position, the marketplace processes an adjustment according to the terms defined in the deal record's dispute resolution field.

If the agents cannot reach resolution through automated data exchange, the flag is escalated to human review: an account manager on one or both sides, or a neutral arbitration service if one is specified in the deal terms. The escalation rate for routine discrepancies should be low in a well-functioning system; the human intervention point is genuine exceptions.

What determines whether a discrepancy is an error or a dispute?

An error is a delivery deviation that both agents agree is outside the committed terms. A dispute is a delivery deviation that the agents disagree about. The distinction is important because errors are resolved by the deal terms (what adjustment does the record specify for this category of deviation?) while disputes require adjudication of competing claims.

In a bilateral deal record system, the rate of genuine disputes (where both agents have different data and different interpretations) should be lower than in a system without bilateral records, because the commitment question is settled and the deviation question is a matter of data rather than interpretation.

What should buyers look for in marketplace dispute governance?

Buyers evaluating agentic marketplace infrastructure for deal governance should check three things. First, whether the marketplace provides a programmatic API for buying agents to raise compliance flags, receive responses and track resolution status. Second, whether dispute escalation paths are defined in the deal record itself, so agents know what happens when automated resolution fails. Third, whether the marketplace publishes resolution time commitments and, where relevant, provides data on actual resolution rates.

A marketplace that handles disputes through account team communication rather than programmatic workflows is not agentic dispute resolution: it is traditional dispute resolution with agentic deal execution bolted on.

Frequently asked questions

What is a deal sheet in programmatic advertising?

A deal sheet is a bilateral record of what both a buying agent and publishing agent committed to — held by the neutral marketplace and used as the reference point if delivery does not match agreed terms.

How do programmatic buyers get a verifiable record of what was agreed?

A verifiable record comes from a bilateral deal record held by the neutral marketplace. Both parties query the same document, and any modification after commitment is logged, giving both sides the same reference point.

What platforms offer tamper-proof deal records for AI media buying?

Agentic marketplace platforms implementing AAMP and holding deal records centrally provide tamper-evident records. The marketplace holds the document; neither buyer nor publisher can modify it unilaterally after commitment.
