A commercial team comparing merchants purely by type label, SME versus marketplace operator, is skipping the constraint that actually narrows the acquisition path first: customer size.
Within the European payment gateway market, customer size is the variable decided first, since a micro merchant and an enterprise-scale merchant reach a provider through genuinely different acquisition channels even when they share the same merchant type label.
This page describes seven merchant type categories, four customer size categories and four merchant acquisition model categories strictly as market segments.
It provides no procurement negotiation guidance, and states no contract value figures for any merchant segment.
A marketplace operator processing enterprise-scale transaction volume will generally be acquired through a different channel than a marketplace operator still at startup scale, despite sharing the same merchant type label.
That is why commercial teams experienced in this market lead acquisition conversations with customer size rather than with merchant type category alone.
Four merchant acquisition model categories complete the picture once customer size is established, spanning direct onboarding, bank-partner deployment, ISV/platform-led acquisition and aggregator-based acquisition.
Micro and small merchants together represent the customer size categories most frequently paired with aggregator-based and ISV/platform-led acquisition, reflecting their preference for low-friction onboarding.
Enterprise-scale customers are generally paired with direct onboarding or bank-partner deployment, reflecting the more tailored commercial relationship these accounts require.
For merchants, establishing their own customer size band relative to a provider's typical acquisition model is the starting point for any provider conversation.
For providers, acquisition model breadth across all four categories widens the addressable share of any merchant's onboarding preference.
Digital-native businesses and marketplace operators frequently sit across more than one customer size band as they scale, a pattern that complicates acquisition planning for providers targeting only one band.
Omnichannel retailers present a related complication, since a single retail brand can carry a micro-scale online storefront alongside an enterprise-scale physical store network under one acquisition relationship.
Recognising that a merchant's size band can shift within a single relationship, not just across separate merchants, is why acquisition model planning benefits from tracking size trajectory rather than a single snapshot.
SME merchants and mid-market enterprises form the two most numerous merchant type categories in this report.
Both are named here as market categories, and this page states nothing about contract values or negotiation leverage for either group.
SME merchants account for the largest merchant type category by count identified in this report.
Mid-market enterprises are generally acquired through a more consultative sales process than SME merchants, distinct from the largely self-service onboarding typical of the SME category.
This grouping as a whole spans the widest range of industry verticals of any merchant type category tracked in this report.
For merchants, the practical difference between SME and mid-market status is less about headcount and more about transaction volume and integration complexity required.
For providers, this grouping remains the largest by merchant count and continues to draw the widest field of aggregator and ISV-led competitors.
Commercially, SME merchants typically pay a higher effective merchant discount rate than mid-market enterprises, reflecting lower negotiating leverage at smaller transaction volume.
This cost positioning is a factor SME merchants weigh alongside onboarding speed, particularly across Poland, Czech Republic and Hungary where SME digital adoption is accelerating fastest.
For merchants, requesting a provider's SME-specific onboarding timeline is a reasonable qualification step given the volume of new digital merchants entering this market segment.
Large enterprise merchants and digital-native businesses form a further merchant type grouping tracked in this report.
Both are named here as market categories, and this page makes no claim about which group generates greater transaction value.
Large enterprise merchants together with digital-native businesses account for a fast-growing merchant type category tied to omnichannel and platform-first commerce models.
Digital-native businesses are generally built on API-integrated or embedded payment infrastructure from inception, distinct from large enterprise merchants that may carry legacy hosted gateway relationships.
Commercially, this grouping requires providers with established multi-currency and cross-border settlement capability, narrowing the field of qualified providers relative to single-market SME acquisition.
For providers, large enterprise and digital-native merchant capability is a meaningful differentiator given the transaction complexity these accounts typically carry.
Merchants in this grouping generally consider hybrid orchestration and multi-provider redundancy a defining commercial requirement rather than an optional upgrade to a standard integration.
Digital-native businesses, by contrast, more frequently prioritise API flexibility and developer experience over the enterprise account management large merchants often expect.

BUYER INSIGHT Digital-native businesses increasingly evaluate a provider's API documentation and developer experience as heavily as its pricing, a shift that is pushing several providers to compete on integration speed rather than merchant discount rate alone. |
Marketplace operators, subscription businesses and omnichannel retailers complete the merchant type dimension tracked in this report.
Each of these merchant types tends to rely on transaction models each merchant type typically needs, since a marketplace operator's split settlement requirement differs fundamentally from a subscription business's recurring billing need.
Marketplace operators require split settlement capability to route funds among multiple sellers on a single platform, distinct from the single-recipient settlement typical of standard merchant accounts.
Subscription businesses depend on recurring billing and tokenised card-on-file infrastructure, generally specified alongside dunning and retry logic for failed renewal charges.
Omnichannel retailers require payment infrastructure that reconciles online and offline transaction data, a category this report notes without describing reconciliation implementation.
For providers, marketplace-specific settlement capability is among the most technically demanding requirements across all seven merchant type categories in this report.
For merchants, the choice among these three types is rarely optional, since it reflects a business model already committed to before a provider conversation begins.
A provider built for standard single-recipient settlement generally cannot simply add marketplace split settlement without a fresh integration, a constraint that shapes vendor selection for marketplace operators specifically.
Micro merchants, small businesses, medium-sized merchants and enterprise-scale merchants form the four customer size categories tracked in this report.
All four are named here strictly as market categories, and this page states no contract value figures for any size band.
Micro and small merchants together account for the largest customer size category by count identified in this report.
Enterprise-scale merchants generate materially higher transaction volume per account than micro merchants, a pattern reflected in this report's acquisition model segmentation rather than in any pricing figure.
Medium-sized merchants sit at an inflection point where self-service onboarding often gives way to a more consultative acquisition relationship.
For providers, customer size band determines which onboarding process, self-service versus consultative, is commercially viable to offer.
For merchants, understanding which size band they fall into helps set expectations for onboarding speed and account management access.
This size dimension cuts across all seven merchant type categories, since a subscription business or marketplace operator can sit in any of the four size bands depending on its own transaction volume.
For a provider building a commercial strategy around this market, deciding which size bands to prioritise is a more foundational choice than deciding which merchant type categories to target first.
Direct merchant onboarding, bank-partner-led acquisition, ISV/platform-led acquisition and aggregator-based acquisition complete the acquisition model dimension tracked in this report.
Which channel a merchant encounters generally depends on the providers each acquisition model favours, since direct onboarding, bank partnerships, ISV integrations and aggregator platforms each draw a distinct set of providers.
Direct onboarding is generally reserved for larger merchants and enterprise accounts, distinct from the lower-friction aggregator-based path typical of micro and small merchants.
ISV and platform-led acquisition is a growing channel, tied to the embedded finance and marketplace-led distribution trend identified among this report's market drivers.
Bank-partner-led acquisition remains particularly relevant across Poland, Czech Republic and Hungary, where banking relationships continue to shape merchant onboarding for mid-market accounts.
For merchants, understanding which acquisition model a provider primarily uses helps set expectations for onboarding speed and ongoing account access.
For providers, acquisition model breadth is increasingly a competitive differentiator as merchants shift acquisition channel while scaling from micro to enterprise size.
This report treats all four categories strictly as acquisition channels and makes no claim about the commercial terms any specific provider offers through them.
SME merchants, mid-market enterprises, large enterprise merchants, digital-native businesses, marketplace operators, subscription businesses and omnichannel retailers are the seven categories this report tracks.
Direct onboarding is generally reserved for larger merchants with a consultative sales process, while aggregator-based acquisition offers lower-friction onboarding typically used by micro and small merchants.
A customer size category defined by materially higher transaction volume than micro, small or medium-sized merchants, generally acquired through direct onboarding or bank-partner deployment.
Because a micro merchant and an enterprise-scale merchant reach a provider through genuinely different acquisition channels even when they carry the same merchant type label, such as marketplace operator.
Yes. Marketplace operators require split settlement capability to route funds among multiple sellers, a technically demanding requirement not shared by standard single-recipient merchant accounts.
Yes. It is tied to the broader embedded finance and marketplace-led distribution trend, becoming a larger channel for new merchant onboarding across this market.
