The Paperwork Fees Nobody Mentions Until a Partner Asks for Proof

2026-09-01

Somewhere between signing with a new payment partner and actually processing your first transaction, an email arrives: "Please provide an official confirmation of your account balance from your banking provider." Or a compliance team asks for an audit letter. Or a lawyer, mid-negotiation, wants written proof that an account amendment actually went through.

None of this is about moving money. It's paperwork triggered by *having* an account — and for crypto, gambling, forex and other high-risk businesses, it comes up more often than founders expect, usually at the exact moment they're least prepared to pay a surprise invoice.

The Request That Comes Out of Nowhere

Most fee conversations focus on the obvious: SEPA and SWIFT transfer costs, currency conversion, card processing rates. Those are priced clearly, quoted upfront, and easy to compare between providers. Administrative documentation is a different category entirely — it's rarely mentioned in onboarding calls, and it only becomes visible the first time someone outside your company (a bank, an acquirer, a new B2B partner, an auditor) asks you to prove something about your account.

That's not a coincidence. Due diligence on high-risk industries tends to be heavier and more frequent than on low-risk ones. A gambling operator opening a new payment corridor, a forex broker onboarding with a liquidity provider, or a crypto exchange applying for a banking relationship elsewhere will typically be asked to produce official documentation more than once a year — sometimes more than once a quarter.

Five Documents, Five Different Prices

On a Polydirection Personal EU account, the "Other fees" section of the public fee schedule lists five distinct administrative charges, separate from transfer and card fees:

- SWIFT/SEPA confirmation — 15 EUR. A written confirmation that a specific transfer was sent or received, often requested when a counterparty disputes receipt or a partner's compliance team wants paper proof. - Compliance audit — 50 EUR. A formal review and documentation of account activity, typically requested by a third party (partner, acquirer, regulator-adjacent process) rather than something the account holder initiates for its own sake. - Official reference letter — 10 EUR. A letter confirming the relationship between the account holder and the bank — commonly requested by landlords, other banks, or business partners as a standard part of onboarding elsewhere. - Amendment request — 15 EUR. Any formal change to account details or terms that needs to be documented and confirmed in writing, not just updated silently in a back-office system. - Standard audit confirmation of accounts and balances — 100 EUR. The most detailed and most expensive of the five: a full, verifiable statement of account status, usually requested for external audits, investor due diligence, or major compliance reviews.

Individually, none of these look dramatic. A reference letter at 10 EUR barely registers next to a SWIFT outgoing transfer fee. But a business that goes through even two or three of these requests in a year — which is common for anyone operating in a regulated or semi-regulated space — is looking at a real, if modest, recurring line item that almost never shows up in a founder's initial budget for "banking costs."

Why High-Risk Accounts Get Asked More Often

The underlying reason isn't arbitrary pricing — it's exposure. Crypto, gambling, forex and dating businesses sit in industries where every party downstream (payment processors, other banks, regulators, sometimes even landlords for a registered office) treats the relationship as higher-risk by default, regardless of how clean the specific business actually is. That translates into more frequent requests for proof: proof the account exists, proof it's in good standing, proof a specific transaction happened the way it was claimed.

A standard e-commerce business rarely needs a compliance audit letter from its bank. A crypto exchange applying for a second banking relationship, or a forex broker being reviewed by a new liquidity provider, runs into this repeatedly — it's simply part of operating in an industry where every counterparty does its own due diligence, on top of what the account provider already did.

When "Free" Banking Isn't Actually Free

This is also where "free account opening, no monthly fees" marketing can be misleading if read too literally. A low headline fee structure says nothing about what happens when a third party needs official paperwork six months into the relationship. For a high-risk business, that paperwork isn't a hypothetical edge case — it's close to a predictable, recurring cost of doing business in a scrutinized industry.

None of the five fees above are unusual or punitive by industry standards — they reflect the actual work involved in producing a verifiable, bank-issued document rather than an unverified export from an online dashboard. The issue isn't that they exist; it's that they're rarely part of the conversation before the first request lands.

How to Plan for It Instead of Getting Surprised

The fix isn't complicated: read the "other fees" section of a provider's public fee schedule before signing up, not after the first compliance audit letter is billed. Ask directly how often documentation requests typically come up for businesses in your specific industry — a crypto exchange and a dating platform will have different documentation profiles even on the same account type. And if your business model involves frequent partner onboarding, investor reporting, or multi-provider payment setups, budget for at least a couple of these requests per year rather than treating them as one-off surprises.

A transparent, itemized fee schedule — the kind that lists a 10 EUR reference letter next to a 100 EUR audit confirmation instead of burying both under "additional fees may apply" — is itself a signal worth paying attention to when choosing a banking partner for a high-risk business.
