Current Card Processing Costs (Annual)
Cost Component Annual Cost (EUR)
Visa/Mastercard Network Licenses
i Network Licenses (FIXED COST) Annual membership fees paid to Visa/Mastercard for network access. Fixed cost regardless of transaction volume.
Include: Base membership, annual participation fees. Typical range: €450K-1.9M. Does NOT reduce with lower volume.
Assessment & Scheme Fees
i Assessment & Scheme Fees Volume-based fees charged by card networks (typically 0.13-0.15% of transaction volume).
Include: Assessment fees, network brand fees. These increased ~30% from 2019-2024
PCI-DSS Compliance
i PCI-DSS Compliance (FIXED COST) Annual costs for Payment Card Industry Data Security Standard compliance. This is a FIXED cost - even with 10 card transactions/year, full compliance is mandatory.
Include: QSA audits (€35K-200K), quarterly scans, penetration testing, infrastructure upgrades, staff training. Typical: €150K-1M. Does NOT reduce with lower transaction volume.
Fraud Prevention Systems
i Fraud Prevention Systems (FIXED COST) Annual costs for fraud detection and prevention technology. Infrastructure must be maintained regardless of volume.
Include: Fraud detection platforms (€200K-1M), AI/ML tools, transaction monitoring, 3D Secure, dedicated fraud team salaries. Typical: €850K-4.6M. Does NOT reduce with lower volume.
Card Fraud Rate (%)
i Card Fraud Rate Fraud losses as % of total card transaction volume.
Bulgaria: 0.076% (highest in EU), EU average: 0.025-0.035%. Use your actual fraud rate.
Chargeback Processing Costs
i Chargeback Processing Costs OPERATIONAL costs only: Staff salaries, dispute management software, investigation costs.
DO NOT include: Network chargeback fees (those are variable), merchant losses, or fraud amounts. Just your internal overhead. Typical: €1M-5M for Tier 1 bank

payware Network Cost
Parameter Value
One-Time Integration Cost (EUR)
i payware Integration Cost One-time cost to integrate with payware network (Year 1 only).
Include: API integration, mobile app updates, testing, certification. Typical: €30K-60K
Annual Network Fee (EUR)
i payware Annual Network Fee Yearly participation fee paid to payware for network access.
Typical range: €100K-300K depending on bank size and volume
Year 1 Network Fee Discount (%)
i payware Year 1 Discount Percentage discount on network fee for the first year (promotional offer).
Example: 50% = first year fee is €100K instead of €200K. 100% = free first year.
payware Revenue Share (%)
i payware Revenue Share (Bank Cost) Percentage of merchant fee that payware takes. Bank keeps the remainder.
Standard: 50-60% to payware, 40-50% to bank. This is a cost from the bank's perspective.
Per-Transaction Cost (EUR)
i Per-Transaction Cost Cost per A2A transaction for processing and infrastructure.
Typical: €0.01-0.03 per transaction
A2A Fraud Rate (%)
i A2A Fraud Rate Expected fraud rate with bank-level authentication (Strong Customer Authentication).
Typical: 0.001-0.010% (90%+ lower than cards due to biometric auth, no card number exposure)
BORICA Inter-Bank Clearing Cost (EUR/txn)
i BORICA Clearing Cost Per-transaction cost paid to BORICA for inter-bank instant payment clearing (BLINK/BISERA). Only applies to inter-bank transactions, NOT closed-loop.
ECB TIPS benchmark: €0.002/txn. BORICA likely similar. Closed-loop transactions avoid this cost entirely.
Closed-Loop Transfer Cost (EUR/txn)
i Closed-Loop Transfer Cost Internal transfer cost for closed-loop A2A transactions (both payer and payee are bank customers). Much lower than inter-bank clearing.
Internal transfers have minimal infrastructure cost. Typical: €0.0001-€0.001/txn. This is a key advantage of closed-loop transactions.
Merchant Fee (%)
i Merchant Fee Fee charged to merchants for A2A transactions (payware standard).
Standard: 0.5% (vs 2-3% for cards). Adjustable for market positioning: 0.3-1.0%
Transaction Source Mix

A2A transactions come from 2 sources. Percentages represent what portion of each baseline (cards and cash) will adopt A2A payments.

Parameter Value
Card Migration (%)
i Card Migration % % of A2A transactions that previously were card payments. These represent cannibalized card volume.
Impact: Lost card revenue BUT saved card costs (usually net positive). Conservative: 30% (less cannibalization), Moderate: 35%, Aggressive: 40% (more willing to disrupt card business)
Cash Digitization (%)
i Cash Digitization % % of A2A transactions that previously were cash payments. Pure new digital revenue for the bank.
Impact: Pure revenue gain, no card cannibalization. Bulgaria still has significant cash usage. Typical: 40-50%
Bank's Card Revenue Share (%)
i Bank's Actual Revenue from Card Transactions The percentage of transaction value YOUR BANK actually receives from card transactions. This depends on your bank's role(s).
<strong>Card Issuer only:</strong> Interchange = 0.2% (debit) to 0.3% (credit), EU regulated. Blended ~0.25%.<br><strong>Merchant Acquirer only:</strong> Acquiring margin ~0.3-0.4%.<br><strong>Both roles (on-us):</strong> Interchange + Acquiring = 0.5-0.7%.<br><strong>Note:</strong> Merchants pay 1.5-2.5% total MDR, but most goes to networks/processors, not the issuer!
Adoption Assumptions (Year 1-5)
Metric Year 1 Year 2 Year 3 Year 4 Year 5
Customer Adoption Rate (%)
i Customer Adoption Rate % of your customers who actively use A2A payments each year.
Conservative: 10-30%, Moderate: 15-50%, Aggressive: 25-75%. BLINK achieved 20% in Bulgaria already.
Closed-Loop % of A2A Transactions
i Closed-Loop % (Network Effect) % of A2A transactions where BOTH payer and merchant bank at your bank. Grows exponentially due to network effects: as more customers/merchants adopt, probability both parties are your customers increases geometrically.
<strong>Key advantage:</strong> Closed-loop saves BORICA clearing costs (€0.002/txn), making these transactions more profitable. Conservative: 5%→33%, Moderate: 8%→58%, Aggressive: 10%→72%.
Customer & Business Impact
Parameter Value
Profit per Customer (EUR/year)
i Profit per Customer Average annual profit your bank earns from one retail customer.

Churn Reduction from Engagement (%)
i Churn Reduction How much churn improves for digitally engaged customers (absolute %).
Research shows: Digitally engaged users are 2.7x more likely to stay. Typical: 2-5% absolute improvement (18% → 15%)
Cross-Sell Rate - Inactive (%)
i Cross-Sell Rate - Inactive % of inactive/less engaged customers who buy additional products annually (baseline).
Typical: 3-8% per year
Cross-Sell Rate - Active A2A Users (%)
i Cross-Sell Rate - Active % of active A2A users who buy additional products annually (enhanced rate).
Research: Engaged customers buy 10% more products. Typical: 15-25% per year
Revenue per Product (EUR/year)
i Revenue per Product Average annual revenue earned from one additional product sold.
Credit card: €80-150, Personal loan: €200-500, Investment: €50-200, Insurance: €100-300. Blended avg: €100-200
% A2A Users Becoming Active
i Conversion to Active % of A2A users who become highly engaged app users (login frequently, use multiple features).
Typical: 60-85%. Users who make payments in-app tend to engage more overall.
