"Payment provider" is used for at least four different roles, which is why comparing two quotes so often turns out to be comparing different things.
Separating them is not pedantry. Each role is a distinct commercial relationship, each is priced differently, and when a payment fails or a payout is late, knowing which one owns the problem is the difference between a fix and a week of being handed between support queues.
The four roles
The gateway captures the transaction. It presents the checkout, encrypts the card details, tokenises them, applies fraud rules and routes the authorisation request onward. It is software. It never touches your money.
The acquirer holds the licence with the card schemes that allows a business to accept card payments at all. It carries the risk if you take payment and fail to deliver — which is why acquirer onboarding is the most demanding step, and why acquirers care about your chargeback ratio far more than your volume.
The PSP is a commercial bundle, usually gateway plus acquiring plus reporting, sold as one product with one contract. Convenience at the cost of granularity.
The settlement account is where the acquirer's payout lands. It is the end of the card chain and the start of your ordinary payment operations — paying suppliers, running payroll, converting currency.
The confusion is understandable: a single vendor may sell you three of the four. The roles remain distinct underneath, and so do the failure modes.
Following a single payment
- A customer enters card details. The gateway captures and tokenises them.
- The gateway routes an authorisation request to the acquirer.
- The acquirer routes it through the card scheme to the issuer, which approves or declines. The customer sees a result. No money has moved.
- Later — usually daily — transactions are captured and cleared in a batch.
- The acquirer settles: net of scheme fees, its own fees, and any reserve, it pays out to your settlement account. Typically T+1 to T+3, longer for higher-risk categories.
Two things follow from step 3 that cause most of the day-to-day confusion. Authorisation is not payment — a customer can be "charged" in their own view days before you have anything. And the amount that settles is never the amount authorised, because fees and reserves come out in between.
Where each role fails, and who to call
| Symptom | Owner |
|---|---|
| Checkout errors, 3-D Secure loops, tokens rejected | Gateway |
| Sudden decline-rate jump on one card type | Gateway routing, or issuer |
| Payout late, or smaller than expected | Acquirer |
| Rolling reserve imposed or increased | Acquirer risk |
| Chargeback disputes and representment | Acquirer |
| Settlement received but cannot be matched to orders | Settlement account / reconciliation |
| Cannot pay suppliers in the currency you settled in | Settlement account |
The last two rows are where businesses most often discover that "the payment provider handles it" was never true. Acquirers pay out; they do not run your treasury.
The pricing you are actually comparing
Quotes are hard to compare because they mix models:
- Blended — one rate for everything. Simple, and it hides that a commercial card costs several times what a domestic debit card does.
- Interchange++ — scheme interchange, plus scheme fees, plus the acquirer's margin, itemised. Harder to read, and the only model in which you can see what you are paying for.
- Fixed per transaction — on top of, not instead of, the percentage.
Then the items that do not appear on the front page: chargeback fees, refund handling, cross-border and currency-conversion surcharges, gateway monthly minimums, PCI compliance charges, and the rolling reserve — a percentage withheld for a fixed period against future chargebacks.
A reserve is not a fee, and it is not lost. But it is your working capital held by someone else for months, and on a growing business it is a substantial and frequently unmodelled cash-flow effect.
Where the settlement account fits
Once the acquirer pays out, the card world is finished with your money and you still have to run a business with it: hold it, convert it, pay suppliers, reconcile it to orders.
That is a separate function from acquiring, and treating it as an afterthought is what produces the familiar problems — settlements arriving in a currency you do not invoice in, netted payouts that cannot be matched to individual orders, and conversion happening twice because funds land in one currency and go out in another.
How this works with 2PayApp
2PayApp sits at the settlement end of this chain, not the acquiring end. Eligible online and offline merchants may use approved 2PayApp account details to receive settlement payouts from acquiring banks, payment service providers and card-acquiring platforms. Funds can be held and settled in EUR, GBP and USD, with access to payment rails including SEPA, SEPA Instant, Faster Payments, SWIFT and ACH.
Card acceptance and processing itself are normally provided separately by the merchant's acquiring provider — 2PayApp does not provide card acquiring.
2PAYAPP LIMITED is registered with FINTRAC as a Canadian Money Services Business. FINTRAC registration is a legal registration requirement; it is not a banking licence and does not constitute an endorsement by FINTRAC. 2PayApp is not a bank. Accounts, currencies, payment rails, account details and acquiring settlement capabilities are subject to onboarding, compliance approval, provider availability and the customer's approved account configuration.
FAQ
Do I need a gateway and an acquirer separately? Not necessarily — a PSP bundles them. Separating gives more control over routing and pricing; bundling gives one contract and one support queue.
Why is my payout smaller than my sales? Scheme fees, acquirer fees, refunds and any rolling reserve are deducted before settlement. An interchange++ statement itemises the difference.
What is a rolling reserve for? Protection against chargebacks on transactions already settled. It is released on the agreed schedule, typically after six months.
Can settlement go to an account in a different currency from my sales? Often, but it means a conversion. Settling into the currency you sell in avoids paying a spread on the way in and again on the way out.
