Processor Markup

Processor markup is the portion of a merchant's card acceptance cost that the acquirer, processor or reseller keeps for itself, after the pass-through costs set by card issuers and card networks. It is the part of the price that is genuinely negotiable, because interchange and network fees are fixed by the schemes and apply to every acquirer in much the same way.

The term is closely related to acquirer markup; the two are often used interchangeably, although processor markup can also describe the margin added by an independent sales organisation or payment facilitator that resells an acquirer's service. Understanding the markup is central to comparing offers, because headline rates often combine it with costs the provider does not control.

The total fee a merchant pays on a card transaction, often called the merchant discount rate, is built from three layers:

• Interchange. The interchange fee is paid by the acquirer to the card issuer and varies with card type, region, merchant category and how the payment was taken.
• Scheme fees. Card networks charge assessment and processing fees to acquirers, which are usually passed to merchants, sometimes as a network assessment fee.
• Markup. The acquirer or processor adds its own margin to cover operations, risk, support and profit.

Only the third layer is the processor's revenue. A merchant who sees a 2.5% total rate may be paying 1.8% in interchange and scheme fees and 0.7% in markup, or the reverse, depending on card mix and pricing model.

The distinction matters because interchange changes only when the networks publish new rates or regulators cap them, while markup can change whenever the provider amends its fee schedule. When interchange falls, for example after a regulatory cap, merchants on bundled pricing benefit only if their provider passes the saving on; otherwise the markup quietly grows. Tracking markup separately is therefore the main way merchants check whether they are sharing in such changes.

Processors express markup in several ways, often combined:

• Percentage markup. A fixed number of basis points added to every transaction's value.
• Per-item fee. A fixed amount per transaction, sometimes called an authorisation or per-transaction fee.
• Account fees. Monthly service charges, statement fees, PCI fees, terminal rental and minimum monthly charges, all of which add to the effective margin.
• Spread on bundled rates. Under flat-rate or tiered pricing, the difference between the merchant's quoted rate and the actual pass-through cost of each transaction is itself the markup, even if it is never shown.

Under interchange-plus pricing, interchange is passed through at cost and the markup is shown as a separate, fixed amount. This is the most transparent model and makes offers directly comparable. Interchange-plus-plus pricing goes further by listing scheme fees as their own line.

Under blended pricing or flat-rate pricing, a single rate covers everything. The markup then varies transaction by transaction: it is large on cheap debit cards and small, or even negative, on expensive premium or commercial cards. Tiered pricing, which groups transactions into qualified, mid-qualified and non-qualified bands, gives the processor discretion over which band a transaction falls into and is often criticised for hiding markup.

Merchants and their advisers analyse statements to calculate the effective markup: total fees paid, minus interchange and scheme fees, divided by sales volume. The result can then be compared with competing quotes. Factors that justify higher markup include high fraud or chargeback risk, low volume, specialised services such as multi-currency settlement, and long settlement delays that the acquirer must fund.

Larger merchants negotiate markups down to a few basis points, while small merchants often accept simpler but more expensive flat rates in exchange for fast onboarding. Changes in markup should be disclosed under the merchant agreement, and some jurisdictions, including the European Union under its interchange rules, require acquirers to show fees for different card categories separately unless the merchant asks otherwise.

Critics argue that complex statements and bundled rates make markup hard for small merchants to see, so they cannot easily compare providers. Unannounced increases, new account fees and long contracts with early termination charges are frequent sources of complaints. Supporters of bundled pricing reply that simplicity has value for merchants who do not want to read interchange tables, and that the processor takes on the risk of an unfavourable card mix.
