What Is Gateway Fee?
A gateway fee is a recurring or per-transaction charge for the payment gateway, the software layer that securely authorizes and routes a card-not-present transaction, an online checkout or a phone order, to the processor, a separate line item from the processor's own transaction and interchange fees, though the two are easy to conflate on a statement.

Gateway Fee explained
A payment gateway does the work of encrypting, authorizing, and routing a card-not-present transaction before it ever reaches the processor. A card-present sale run through a physical terminal doesn't need this layer the same way, which is why gateway fees show up almost exclusively on accounts doing meaningful e-commerce or phone-order volume.
Gateway fees are typically billed as their own monthly charge, per-transaction charge, or both, separate from the processor's interchange-plus markup. That separation matters when calculating a merchant's real effective rate, since an e-commerce or phone-order-heavy business's true all-in cost has to count the gateway fee as its own line, not assume it's already baked into the quoted processing rate.
Like a monthly minimum or a PCI compliance fee, a gateway fee is exactly the kind of recurring charge a real statement analysis is built to surface. It's easy for a merchant to lose track of a modest monthly gateway charge sitting quietly alongside their processing fees, especially if they've never actually reviewed their own statement line by line.
Why it matters when you're buying
If a prospect processes meaningful volume online or by phone, ask about their current gateway fee specifically, not just their processing rate, since a "cheaper rate" pitch that ignores a real gateway cost isn't the full comparison the merchant thinks they're getting.
