Boost Order Conversion by Reducing Avoidable Card Declines

Antom Card Revenue Booster helps recover lost revenue through card payment optimisation

Not all card declines are real. Many are avoidable, and they cost merchants real revenue. Card payments are one of the most important payment methods in online transaction scenarios but they are also frequently impacted by unnecessary declines.

Merchants typically see one outcome: payment failed. A customer may have sufficient funds, yet the transaction does not complete successfully. They retry with the same card, switch cards, or attempt again later—often with the same result. During online sales campaigns, decline rates may rise sharply without a clear explanation. The result is immediate revenue loss and reduced customer trust.

What merchants do not see is the complexity behind these outcomes. The card payment ecosystem is real-time, dynamic, and fragmented. The same checkout attempt can be evaluated differently across issuers, and even within the same issuer, authorisation decisions can shift based on time, volume, fraud pressure, and operational thresholds. Failures can be difficult to diagnose and often invisible to end users.

Revenue growth does not always require more traffic acquisition

When decline drivers are not visible, many merchants attempt to offset conversion loss by spending more on acquisition. However, a meaningful share of “lost revenue” can be recovered by improving outcomes of transactions that already reach the checkout stage.

This is the role of Antom Card Revenue Booster: optimising the last mile of card payments to reduce avoidable declines and recover incremental revenue.

Results at scale: AliExpress* during peak campaigns

Antom Card Revenue Booster has been applied in large-scale, high-volume environments. For example, during AliExpress’* major 2025 sales campaigns, Antom delivered:

• 2–3% uplift in card authorisation rate
• Approximately 2% of orders recovered through automated retry strategies
• More than 1% incremental improvement through intelligent optimisation of routing and detailed strategy parameters

Note: Results are based on controlled experiments (A/B testing) using real merchant transaction data. Due to privacy and compliance requirements, results are presented in aggregated form.

These improvements were achieved without increasing user traffic or changing customer behavior.

Antom Card Revenue Booster: Intelligent optimisation for card performance

Improving authorisation rates typically requires coordinated optimisations across routing, messaging, authentication, and, credential usage and management.

Antom Card Revenue Booster uses AI to move beyond passive processing and continuously optimise authorisation strategy for each transaction in real time.

Key capabilities

1. Smart Routing selects the best-performing authorisation route based on real-time route stability and success rates.
2. Adaptive Messaging aligns transaction messaging formats with issuer expectations to reduce unnecessary declines caused by mismatches.
3. Authentication Intelligence assesses each transaction, and applies verification only when needed, reducing unnecessary friction while ensuring compliance.
4. Active Retry recovers transactions impacted by temporary issuer conditions such as temporary issuer-side constraints, transient instability, or momentary tightening of risk thresholds.
5. Credential Lifecycle Management reduces avoidable failures caused by outdated credentials. It leverages Network Tokens and Account Updater capabilities to maintain continuity when card details change due to expiration or replacement.

Recover incremental revenue at the last mile

Antom continues to build best practices across industries and regions, helping merchants identify and resolve hidden causes of payment loss across the card payment journey.
