Grow merchant volume without losing portfolio control
Decision Deck helps acquirers, PSPs, PayFacs and embedded payment platforms manage the merchant book as it changes. Use scheme headroom where it can grow conversion. Tighten controls before fraud or chargebacks breach limits. Protect profitable merchants from churn. Keep reserves, payout rules and risk actions tied to evidence.
Higher TPV · better merchant retention · stronger scheme control · lower tail loss.
Make scheme headroom usable capacity
Fraud and chargeback thresholds are usually treated as limits to avoid. That leaves money on the table when a merchant has safe headroom and controls are tighter than they need to be.
Decision Deck helps you dynamically loosen or tighten controls based on real headroom.
Components used
- Forecasting
Predicts fraud, dispute and chargeback movement over the next 30, 60 and 90 days.
- Risk Stratification ↗
Separates merchants with usable headroom from merchants approaching scheme limits.
- Policy Dynamics ↗
Sets buffers, thresholds and permitted actions by merchant, MID, scheme, product and risk appetite.
- Recommendations Block ↗
Selects the action: loosen screening, keep controls stable, add targeted friction, tighten rules or route for review.
- Simulation
Tests the effect on TPV, fraud ratio, dispute ratio and breach probability before change goes live.
Differentiate between good growth and merchant risk
Not every increase in volume is good growth. A merchant can grow because demand is healthy, because fraud is rising, because disputes are lagging or because riskier traffic is being approved.
Decision Deck distinguishes healthy merchant growth from growth that changes exposure.
Components used
- Predictive models
Estimate volume trajectory, fraud propensity, dispute risk, financial stability and expected margin.
- Behavioural Dynamics ↗
Turns merchant volume, refund behaviour, dispute movement, customer complaints and settlement patterns into merchant state signals.
- Risk Stratification ↗
Separates healthy, watching, at-risk and critical merchant states.
- Noise Resilience ↗
Separates seasonality, campaign spikes and sparse-data noise from meaningful risk movement.
- Monitoring
Tracks state changes and alerts teams when merchant behaviour starts to move.
See chargeback pressure before it becomes a problem
Chargebacks lag and a merchant can look healthy today while today’s transactions are creating future chargeback pressure.
Decision Deck forecasts chargeback risk before the scheme ratio shows the full damage.
Components used
- Forecasting
Models time-to-chargeback, dispute lag and future pressure.
- Multi-output models
Estimate chargeback risk, representment outcome, operational burden and margin impact together.
- Risk Stratification ↗
Separates merchants where dispute pressure is manageable from those moving toward breach.
- Recommendations Block ↗
Selects the next action: targeted merchant remediation, tighter screening, reserve adjustment or escalation.
- Policy Dynamics ↗
Controls actions by reason code, scheme rule, merchant segment and risk appetite.
Reserves and payout controls match the real exposure
Holding too much reserve damages merchant experience and increases churn risk. Holding too little creates long tail loss risks.
Decision Deck can help you dynamically size reserves and payout controls based on evolving tail exposure.
Components used
- Predictive models
Estimate financial stability, delayed dispute exposure, exposure-at-failure and likely recoverability.
- Forecasting
Projects future chargebacks and refund pressure after settlement.
- Policy Dynamics ↗
Defines reserve levels, payout delays, holdbacks and approval requirements.
- Recommendations Block ↗
Selects the control: standard settlement, delayed payout, reserve amount and release or review.
- Exception Handling ↗
Catches high-impact cases where normal payout logic is unsafe.
See merchant churn signals early
A profitable merchant may leave because of pricing, settlement friction, risk controls, support issues or competitor pressure. By the time processing volume drops, the relationship may already be damaged.
Decision Deck identifies merchants at risk of churn and recommends the action most likely to protect value.
Components used
- Predictive models
Estimate churn probability, time-to-churn, revenue at risk and upsell potential.
- Behavioural Dynamics ↗
Reads declining volume, partial churn, share-of-wallet movement, support friction and risk friction.
- Recommendations Block ↗
Selects the action: pricing review, product offer, settlement fix, support route, risk-control adjustment or relationship manager intervention.
- Case Triage ↗
Prioritises merchants by revenue at risk, margin, strategic value and likelihood of saving.
- Monitoring
Tracks whether interventions protect TPV and merchant lifetime value.
Lower the cost of review teams
Review teams can drown in alerts. Static thresholds send too many ordinary cases to review and miss merchants whose behaviour is changing in more important ways.
Decision Deck prioritises portfolio review by value, urgency, risk movement and consequence.
Components used
- Case Triage ↗
Ranks merchants for risk, commercial value, evidence strength, urgency and actionability.
- Risk Stratification ↗
Separates normal monitoring from merchants that need portfolio, risk, compliance or commercial attention.
- Noise Resilience ↗
Reduces unnecessary review caused by seasonality, small denominators and ordinary volatility.
- Recommendations Block ↗
Suggests the next action and the review owner.
- Evidence Vault ↗
Gives the reviewer the drivers, policy context and action history.
Test changes before they hit your merchants
A new screening rule, reserve policy, payout rule or chargeback threshold can move revenue and risk quickly. The wrong change can reduce TPV, increase churn, flood review teams or create scheme exposure.
Decision Deck tests portfolio actions before they reach merchants.
Components used
- Simulation
Tests policy changes, threshold movement, reserve rules and screening controls against portfolio data.
- Predictive models
Estimate impact on TPV, margin, fraud, chargebacks, breach risk, churn and review volume.
- Policy Dynamics ↗
Versions portfolio rules and supports controlled rollout and rollback.
- Monitoring
Shows whether live outcomes match the expected impact.
- Evidence Vault ↗
Links merchant outcomes to the policy, model and decision logic active at the time.
Manage the merchant book as it moves
Decision Deck helps payment providers grow volume where it is safe, tighten controls where exposure is rising and protect the merchants worth keeping.
Use it to manage merchant state, scheme headroom, chargeback pressure, reserves, churn and portfolio policy with stronger control.
