MANDATESHIELD FOR MARKETPLACES

Policy enforcement for multi-merchant agent checkout

Normalize seller and checkout evidence across a marketplace, then enforce the customer's limits consistently at execution.

Who this is for

Marketplaces, booking platforms and aggregators where an agent can compare, select and buy from multiple sellers.

The execution risk

Search and ranking steps can change sellers, fees and availability between approval and payment. Marketplace complexity makes merchant binding and final-total validation essential.

How the control fits

  1. Represent the selected seller with a stable marketplace merchant ID.
  2. Include fees, taxes and shipping in the final amount.
  3. Evaluate the purchase against the original customer mandate.
  4. Persist a receipt before the order is committed.

The operational result

One policy layer protects many sellers and agent protocols without embedding model-specific logic in every checkout.
