Pillar8 operates as a decision layer positioned before payment execution. It sits between the merchant checkout and the existing payment stack, generating a decision package for each checkout session.

System Flow

Shopper → Merchant Checkout → Pillar8 Decision Engine → Orchestrator / PSPs → Issuer

​
Decision Package

For each session, Pillar8 returns:
  • Ranked payment methods — Ordered by relevance and success likelihood
  • Contextual scoring signals — Transaction pattern evaluation
  • Confidence indicators — Decision certainty metrics
  • Gating and eligibility logic — Access controls and rules
The package can be applied by different execution surfaces depending on the checkout environment.

​
Execution Surfaces

Pillar8 guides shoppers through an advisory block displayed in checkout.
Merchants can apply the decision package by:
  • Highlighting payment options
  • Reordering methods
  • Shaping checkout behavior
Decisions and outcomes are captured and surfaced in the merchant portal for analysis.

​
Platform Dependency

How the decision package is applied depends on the merchant’s environment and checkout control. Some platforms support guidance only, while others allow deeper checkout execution.
