Interchange++ pricing itemizes the three components of every card transaction fee — interchange, network scheme fees, and processor markup — instead of bundling them into one blended rate. Tiered pricing is a third option, generally worse than either. If you’re still deciding which pricing model fits your store, see Flat Rate vs Interchange Plus: Which Pricing Model Is Right for You? for the full comparison, break-even framework, and why to avoid tiered pricing. For a deeper look at interchange++ mechanics and who it genuinely suits, see WooCommerce Interchange++ Pricing: How It Works and Who It’s For.
This guide answers a narrower question: you’re already on interchange++, or evaluating a processor that offers it, and you want to know how to actually read the statement and verify what you’re being charged.
What an Interchange++ Statement Shows You
A properly structured interchange++ statement breaks out:
- Interchange by card category (consumer debit, consumer credit, rewards, business, etc.)
- Scheme fees (Visa assessment, Mastercard assessment, cross-border fees where applicable)
- Processor markup — the fixed rate and per-transaction fee you agreed to
- Total effective rate for the period
This level of detail lets you audit your costs, spot unexpected card-mix shifts, and verify that you’re actually being charged what was agreed. With blended pricing, none of this is possible.
Interchange rates themselves are published by Visa and Mastercard and change periodically — rather than repeat a schedule here that can drift out of date, see Interchange Fee Calculator: Estimate Your True Processing Costs for the current breakdown by card type. What matters when auditing your own statement is comparing your actual blended rate against your real card mix, not the published schedule in isolation.
How the Processor Markup Works
Your processor’s markup is the only negotiable component. Under interchange++, it’s typically expressed as a small percentage plus a per-transaction fee — for example, 0.20% + $0.10 per transaction.
This markup is significantly smaller than it appears in blended pricing comparisons. When processors quote a blended 2.9% + $0.30, much of that covers interchange and scheme fees. The actual processor profit on a typical transaction mix might be 0.3%–0.7% of volume, but you’d never know it from a blended rate card.
Under interchange++, the markup is explicit. You can compare it directly between providers and verify it on every statement.
Interchange Optimization
One advantage of interchange++ pricing: it gives you visibility into interchange costs, which creates an incentive to optimize them. Tactics that reduce interchange include:
- Submitting complete transaction data — certain interchange categories require specific data fields; missing them causes a “downgrade” to a higher-cost tier
- Using address verification (AVS) — required for some lower interchange tiers on CNP transactions
- Enabling debit routing — for eligible debit transactions, routing via PIN-debit networks can reduce interchange
- Minimizing chargebacks — high chargeback rates can trigger interchange penalties
Processors on blended pricing have no financial incentive to help you optimize interchange — their margin doesn’t change. On interchange++, both you and your processor benefit from lower interchange costs.
Where ConvesioPay Fits
ConvesioPay does not use interchange++. ConvesioPay processes at a flat 2.9% + $0.30 per transaction, with no monthly fees and no minimum invoice.
That’s a deliberate choice, and the trade-off is the one described above: interchange++ can be cheaper at high volume with a favorable card mix, while a flat rate is predictable and needs no modeling, no reconciliation, and no card-mix analysis to understand.
As a rough guide: interchange++ can be worth exploring once you clear about $10,000/month in volume, but it doesn’t reliably pay off until you’re past roughly $40,000/month, once card-mix and reconciliation overhead are factored in. Newer or smaller merchants are usually better served staying on a flat rate until they’re firmly in that higher range. If you’re processing at a scale where itemized interchange would save you meaningfully, that’s a conversation worth having with us — and sometimes the honest answer is that you should go direct to an acquirer instead.
What the flat rate buys you is access. As a certified Adyen partner, ConvesioPay runs on Adyen’s infrastructure — dynamic 3D Secure routing, native Apple Pay optimization, and enterprise fraud tooling — with no minimum invoice and no volume commitment to qualify for it.
