Channel conflict in merchant acquiring and risk mitigation
Competitiveness in payments is inherent and often measurable. Sales organizations operate in a results-driven environment where performance is quantified. Operational teams are evaluated more subjectively, often based on consistency, control and risk mitigation. This dynamic becomes particularly important when channel conflict arises.
Within a single organization, channel conflict is typically a matter of internal policy and compensation equity. However, when multiple third parties, ISOs, ISVs, agents and fintech partners submit the same merchant through a common processor or acquirer, the issue extends beyond compensation. It presents legal, operational and regulatory risk.
Where channel conflict creates risk
Sales channel conflicts, when multiple parties are submitting through a common processor or acquirer, represent greater risk than when a single party is submitting. A processor or acquirer may be subject to a dispute if there is ambiguity as to the entity entitled to the residual.
Additionally, if multiple entities are submitting the same merchant through a single processor or acquirer and the merchant is allowed to set up multiple MIDs, there could be a disconnect if adverse action is taken against one MID but not consistently applied to all MIDs.
This could result in brand damaging fines, reputational risk, regulatory action and legal risk. Processors and acquirers need to establish channel policies such that conflicts are adjudicated in accordance with policies.
Multiple MIDs and legitimate use
There are legitimate scenarios where a merchant may maintain multiple MIDs with the same acquirer. For example:
- A merchant using separate providers for a unique vertical (for example, petroleum) and a fast casual take-out or convenience store;
- Distinct business lines or processing environments requiring differing solutions.
In these cases, multiple MIDs are appropriate, but they must not operate in isolation. Acquirers must:
- Link related MIDs at the merchant level;
- Maintain a holistic view of exposure;
- Ensure consistent application of controls and adverse actions.
The critical failure point: inconsistent action
A common breakdown occurs when adverse action is taken against one MID but not others tied to the same merchant. For example, if a new beneficial owner is identified on one account and that individual is subsequently flagged through OFAC or other risk screening, failure to propagate that information across all related MIDs represents a serious control gap.
From a regulator’s perspective, the institution had the information but failed to act on it comprehensively. This is not a data issue. It is a governance failure.
Residual ownership: a legal exposure
Channel conflict also creates uncertainty in residual allocation. When multiple parties submit the same merchant:
- Which entity is entitled to compensation?
- What happens when compensation structures differ by channel?
- Approaches vary across the industry:
- First in” submission rules;
- Merchant attestation of sales representation;
- Blocking duplicate submissions;
- No formal policy at all….all accounts accepted.
The absence of a defined approach increases the likelihood of disputes and litigation.
Selling into the existing portfolio
Processors and acquirers need also establish policies for selling into their existing book of business. Sales entities will nearly always be excluded from moving their existing merchants to other providers. Some will also attempt to limit their sales entities from soliciting any merchant within their portfolio. Sales entities should consult an industry attorney to ensure they are not inappropriately limiting their addressable market.
Channel conflict is unavoidable, but the downside should be managed. To mitigate channel conflict, processors and acquirers should anticipate it. They need simple but consistent policies that reflect how such instances will be addressed. They will also need systems that identify and link multiple MIDs from the same merchant, as well as ensure adverse action is consistently applied.
Third-party oversight includes managing channel conflict.
The solution is clarity and consistency, including:
- Clear policies;
- Normalized and linked data;
- Coordinated action.
In an environment where regulators increasingly expect banks and acquirers to demonstrate control over their third parties, channel conflict is no longer a commercial nuisance. It is a risk management obligation.
