Blended vs Interchange++: The Expert's Guide to Choosing Your Pricing Strategy

Most businesses believe they are choosing between Blended Pricing and Interchange++ (IC++) based on which one is "cheaper." In reality, you are choosing between predictability and exposure, simplicity and scrutiny, and operational tolerance versus financial optimization.

This guide strips away the marketing language to explain what each model actually does, why neither is "better" in isolation, and why the wrong choice can quietly cost you far more than a higher headline rate.

The Two Pricing Models, Stripped of Marketing

To make an informed decision, you must understand how these models function in the real world, beyond the sales brochures.

What Blended Pricing Really Is

Blended pricing means you pay a single, averaged rate for most (or all) card transactions. For example, a rate of 1.75% + £0.20 per transaction. This rate is a "black box" that already includes:

• Interchange Fees: The base cost set by the card networks.
• Scheme Fees: Fees paid to Visa or Mastercard.
• Provider Margin: The processor's profit.
• Risk Buffering: A premium paid to the provider to absorb cost volatility.

Blended pricing is not "opaque" by accident. It is designed to remove volatility. The provider absorbs the variation in underlying costs, giving you a predictable line item on your balance sheet.

What Interchange++ Really Is

Interchange++ breaks the cost into its raw components: Interchange + Scheme Fees + Provider Markup. Your cost changes dynamically depending on:

• Card Type: Debit, Credit, Corporate, or International.
• Geography: Where the card was issued vs. where you are located.
• Authentication: Whether the transaction used 3D Secure (3DS).
• Transaction Risk: The specific risk profile of the individual payment.

Interchange++ exposes the true economics of every payment, including the parts that don't always work in your favour.

The Strategic Trade Off: Predictability vs Optimization

The conflict in most pricing discussions is the assumption that IC++ is always better for larger businesses. This is a dangerous oversimplification.

Why Blended Pricing is Often the Safer Choice

Blended pricing is frequently dismissed as "expensive," but this misses its primary value: Insurance. It is often the superior choice when:

• Card Mix is Volatile: If your customers use a wide variety of international or corporate cards, a blended rate protects you from sudden cost spikes.
• Stable Margins are Critical: If your business values predictable cash flow over theoretical marginal savings.
• Operational Complexity is High: In models with time delayed fulfillment or high refund sensitivity, the simplicity of a blended rate reduces reconciliation risk.

When Interchange++ Actually Delivers Savings

Interchange++ tends to work best when your business has reached a level of Operational Maturity. It is attractive when:

• Domestic Debit Dominance: If the majority of your transactions are domestic debit cards, IC++ will almost always be cheaper than a blended rate.
• High Transaction Consistency: When your ticket sizes and card types are predictable and stable.
• Strong Technical Integration: When you have the systems in place to monitor and optimize for different card types and authentication methods.

The Question No One Asks: How Will This Be Underwritten?

Two businesses with identical turnover can receive completely different pricing structures because their Risk Profiles behave differently over time.

The Real Risk: Choosing the Wrong Model Too Early

Many businesses lock themselves into a pricing model before they fully understand how their transactions will evolve or how providers respond to their growth. The result is often:

• Sudden Pricing Adjustments: Providers re classifying your business as your volume spikes.
• Forced Provider Switches: Realizing your current processor's risk appetite doesn't match your new scale.

The Only Sensible Starting Point

Before comparing rate cards, the correct first step is understanding your Marketability to Providers. You need to know:

1. How providers will assess your specific risk profile.
2. Which pricing structures they will actually support for your business model.
3. Where your business sits on the "Tolerance Spectrum."

This requires a Pre Underwriting Assessment, not a simple quote request. Once you know which providers will genuinely partner with your business, pricing becomes a strategic decision, not a gamble.

The decision isn't "Which is cheaper?" It's "Which model will still work for my business six months from now?"
