Kurv Review 2026: Interchange-Plus Pricing for Brick-and-Mortar Retailers

Who is Kurv designed for?

Kurv positions itself as a transparent interchange-plus processor for merchants who sell primarily in person. If you operate a retail counter, service desk, or field-based business and your monthly card volume exceeds roughly $5,000, interchange-plus pricing can reveal savings that flat-rate aggregators obscure.

The Federal Reserve's 2023 Payments Study found that the weighted-average interchange fee for general-purpose card transactions in the U.S. was approximately 24 basis points for debit and varied significantly for credit depending on card type and entry method. Kurv's model lets you see exactly where your money goes in that stack.

How does Kurv's pricing compare to flat-rate models?

Most aggregator processors — including Square and Stripe — bundle interchange, assessments, and processor margin into a single blended rate. That simplicity is valuable for micro-businesses but becomes expensive as volume grows.

Kurv separates the interchange component (set by Visa and Mastercard), the network assessments, and its own markup. This means your effective rate shifts with your actual card mix rather than subsidizing someone else's rewards card costs.

Key question to ask your Kurv rep: Request a side-by-side statement analysis comparing your current effective rate to their quoted markup over interchange. Any credible processor will do this before you sign.

What does the onboarding process look like?

Unlike self-serve platforms where you enter a bank account and start swiping, Kurv uses a consultative model. A rep reviews your MCC (merchant category code), typical transaction sizes, and chargeback history before quoting.

This is both a strength and a friction point. You get pricing tuned to your business — but you cannot start processing until underwriting completes, which typically takes 2–5 business days according to merchant feedback.

What should you verify on the contract?

Before signing any merchant services agreement — Kurv or otherwise — confirm these line items in writing:

• Effective rate guarantee: Does the quoted markup hold for at least 12 months?
• PCI compliance fees: Some processors charge $15–$30/month; verify if this is included
• Early termination language: Look for liquidated-damages clauses and their dollar amounts
• Batch settlement timing: Confirm next-day or same-day funding windows
• Equipment terms: Is hardware purchased, leased, or subscription-based?

The Electronic Transactions Association (ETA) publishes best-practice guidelines for merchant agreements that are worth reviewing alongside any proposal.

How does Kurv compare to Square and Stripe?

For a head-to-head look, see our Kurv vs Square and Kurv vs Stripe comparison pages. The short version: Square wins on speed-to-first-sale; Stripe wins for online product teams; Kurv wins when in-person interchange economics are the priority and you want a human to walk you through the numbers.

What is our editorial verdict?

Kurv earns a 4.5 out of 5 in our scoring framework, which weights pricing transparency (35%), onboarding quality (20%), support responsiveness (20%), contract fairness (15%), and typical SMB fit (10%). The quote-based model means you must do homework, but the upside is a rate structure that actually reflects your card mix rather than a blended average designed for the aggregator's margin.
