Open banking payments are moving from early-adopter novelty to mainstream infrastructure across regulated iGaming markets. For operators evaluating the switch, the real question is not whether the technology works, but whether the unit economics justify the integration effort and ongoing costs. Here is a practical look at what operators are actually paying and what they are getting back.
What Open Banking Payments Actually Cost
Unlike card processing, open banking runs on account-to-account (A2A) rails, which removes card-scheme fees from the equation. In practice, operators pay a per-transaction fee to their payment service provider (PSP) ranging from roughly 0.10 EUR to 0.30 EUR for standard bank transfers in markets such as the United Kingdom, the Netherlands and Germany. That compares favourably to blended card costs that routinely land between 1.5 percent and 2.5 percent of transaction value once interchange, scheme fees and PSP margins are stacked together.
On a 200 EUR deposit, the saving can be 3 EUR to 4 EUR per transaction. Across a mid-sized operator processing 50,000 deposits per month, that arithmetic becomes material quickly. However, the flat-fee structure means the advantage narrows on small deposits. Operators whose player base skews toward micro-deposits below 20 EUR should model this carefully before assuming open banking is universally cheaper.
Integration and Ongoing Operational Costs
Direct integration with an open banking aggregator, rather than routing through a generic PSP layer, typically involves a one-time technical setup fee between 5,000 EUR and 20,000 EUR depending on the aggregator and the operator's existing tech stack. Monthly platform fees or minimum volume commitments are common. Operators should also budget for:
- Compliance mapping: open banking consent flows must align with local PSD2 obligations and any gambling-specific responsible gaming checks
- Player support training: staff need to understand declined bank connections, re-authentication prompts and bank-side friction for customers
- Reconciliation tooling: A2A settlement timing differs from card schemes and requires updated treasury and reconciliation processes
- Fallback routing: a proportion of players will not have a supported bank or will abandon the consent flow, requiring card or alternative methods as backup
Realistic total first-year costs for a standalone integration, including internal engineering time, sit between 30,000 EUR and 80,000 EUR for a mid-market operator. Operators using a managed-services partner can reduce that figure significantly by leveraging pre-built integrations and shared compliance infrastructure.
The Return Side of the Equation
The economics of open banking improve substantially when operators look beyond direct fee savings to conversion, fraud and retention metrics.
Deposit Conversion and Speed
Instant bank payments settle in seconds, removing the uncertainty that causes players to abandon a deposit mid-flow. Operators who have deployed open banking in the UK market report deposit success rates of 92 percent to 97 percent compared to 85 percent to 90 percent for cards, where declines from issuer fraud scoring are a persistent drag. Even a 5 percentage-point improvement in conversion on a high-volume product has outsized revenue impact.
Fraud and Chargeback Reduction
Because payment is authorised directly from the player's verified bank account using strong customer authentication (SCA), chargeback risk is dramatically lower. Operators in markets with high card-fraud rates have reported chargeback rates dropping to near zero on open banking volumes. Fraud team overhead and the costs of dispute management decrease accordingly.
AML and KYC Efficiency
Open banking provides verified account ownership data at the point of payment. This supports source-of-funds verification without additional friction and can reduce manual enhanced due diligence (EDD) costs for compliant operators. MLRO teams can use bank account data as a supplementary signal in transaction monitoring, improving detection quality rather than just adding another data silo.
Player Lifetime Value
Players who deposit via open banking show higher redeposit rates in several operator cohort studies, likely because the frictionless experience reduces the psychological barrier to returning. Higher redeposit frequency directly lifts lifetime value and lowers effective customer acquisition cost over the player relationship.
What Operators Should Model Before Committing
A sound business case requires operators to model at least three scenarios: a conservative case based on current average deposit values and volume, a base case incorporating realistic conversion uplift, and an optimistic case including chargeback savings and AML efficiency gains. Operators with average deposits above 100 EUR, meaningful card-decline rates and exposure to chargeback disputes will find the economics most compelling. Those with very low average deposits or geographies where open banking bank coverage is still thin should phase adoption rather than replace card infrastructure wholesale.
Open banking is not a cost-cutting exercise. It is a margin and quality improvement that compounds across fraud, conversion and compliance simultaneously, provided operators implement it with the right payment mix strategy.
