Payment Service Provider (PSP)
A payment service provider (PSP) is an intermediary company that connects a gambling operator to card networks, banks, and e-wallets so players can deposit and withdraw money through a single integration.
Definition
A payment service provider (PSP) sits between an operator and the wider payments system, giving the operator access to many payment methods — cards, bank transfers, e-wallets, open banking, and local options — through one technical integration and contract rather than a separate connection to each. It routes each deposit and withdrawal to the appropriate acquiring bank or card scheme and handles authorisation, settlement, currency conversion, and reconciliation, usually layering on fraud screening, chargeback management, and tokenised storage of card details. PSPs charge the operator per transaction (typically a percentage plus a small fixed fee) and, for gambling, classify the business as a high-risk merchant category (MCC 7995), which means higher fees, stricter onboarding, rolling reserves, and a smaller pool of willing providers. A PSP normally does not hold the gambling licence or the player's gaming balance — it moves money in and out — but it is an important control point for AML checks, fraud prevention, and payment-method restrictions.
Worked example
Suppose an operator integrates one PSP that connects it to Visa, Mastercard, and the Skrill e-wallet through a single API. A player deposits EUR 100 by card; the operator credits the full EUR 100 to the player's balance but pays the PSP a processing fee — for a high-risk gambling merchant (MCC 7995), a blended rate of roughly 2.5% plus a small fixed fee is realistic — so about EUR 2.70 leaves the operator on that one deposit. Across EUR 1,000,000 of monthly deposits at a 2.5% blended rate, PSP fees alone cost around EUR 25,000, a direct expense deducted before Net Gaming Revenue (NGR). If a card deposit is declined, a capable PSP (or an orchestration layer sitting above several PSPs) can "cascade" the attempt to a second acquirer to rescue the transaction, because a failed deposit is often a lost player. Note that because gambling carries elevated chargeback and fraud rates, PSPs commonly require rolling reserves and can suspend a merchant that breaches a card scheme's dispute-rate thresholds.
Why it matters
Payments are both a core cost line and a conversion bottleneck: PSP fees eat directly into margin, and the provider's acceptance (approval) rate determines how many deposits succeed, so a poorly performing PSP quietly loses real revenue at the cashier. Because gambling is a high-risk, sometimes restricted category, operators often have limited PSP choices, face reserves and de-risking, and run several providers in parallel with cascading to stay resilient — making payment strategy a genuine competitive and operational concern. PSPs are also a compliance chokepoint: they enforce AML and fraud screening, help block prohibited methods (for example, credit cards where these are banned for gambling), and support source-of-funds and closed-loop rules. For players, the PSP explains why some cards decline, why withdrawals frequently return to the original deposit method, and why payouts can be delayed while checks clear.

Note: Fee percentages, fixed fees, and reserve terms are illustrative and vary widely by risk profile, region, payment method, volume, and negotiation; gambling's high-risk classification generally pushes rates well above standard e-commerce. The industry uses "PSP", "payment gateway", "acquirer", and "payment processor" loosely and sometimes interchangeably, though they refer to technically distinct roles. Which methods are available, whether a PSP will serve gambling at all, and specific rules differ sharply by jurisdiction and licence — for example, the UK banned gambling on credit cards from 14 April 2020, and card-scheme dispute-monitoring thresholds change over time.
