Your Payroll Provider Is Making More Money on FX Than They Charge You in Fees

TL;DR

• Most global payroll providers embed their largest margin inside the foreign exchange rate, not the platform fee. It never appears as a line item on your invoice.
• The industry norm for FX markup at traditional payroll providers runs between 4 and 6 percent above the mid-market rate. At any real payroll volume, this adds up to tens of thousands of dollars a year.
• Providers that hold your funds before disbursement earn yield on the float period on top of the FX margin. You pay twice without knowing it.
• A transparent FX structure means the rate is disclosed, contractually capped, and listed as a separate line item on every invoice.
• Stablecoin-to-stablecoin payments carry no FX component at all. When local currency conversion is needed, the fee should be explicit and capped in your contract.

What Is Actually Happening

Your payroll provider has two fee structures. One is on your invoice. The other is not. The one that is not on your invoice is almost always larger. This is not a hidden clause or a compliance technicality. It is how global payroll providers are designed to make money, and most of their clients never figure it out until they ask the right questions.

How Do Traditional Payroll Providers Profit From Foreign Exchange?

When you pay an employee or contractor in a currency other than the one your treasury holds, a conversion has to happen somewhere. That conversion is a revenue event for whoever controls it.

Traditional payroll providers control it. They receive your funds, hold them until disbursement, and convert at a rate they set internally. The difference between the mid-market rate and the rate they apply is their margin. They do not need to charge you a high platform fee. They make their money on the spread.

This is not new. Banks have operated this way for decades. What is different in global payroll is the opacity. When you exchange currency at a bank, you can see the rate and compare it to the published mid-market rate. In a payroll invoice, the FX margin is folded into the output amount. You see what your contractor received. You do not see the rate applied to get there.

The margins add up fast. Providers that sit on funds before disbursement compound the problem. They earn yield on your money in the float period and then charge you on conversion on top of that. At 4 to 6 percent FX markup, the amount extracted from a global payroll program at any real scale is significant. Most finance teams never calculate it because it never appears as a line item.

Why Can't You Find the FX Line Item on Your Invoice?

Pull up your last invoice from your payroll provider. Find the line item for foreign exchange fees. If you cannot find it, that is not an accounting error. That is a design choice.

Most payroll providers do not list FX as a separate charge. They quote you a rate, apply it to the transaction, and show you the output. The difference between the rate they applied and the actual mid-market rate is revenue they keep. It never appears on paper as a fee because it technically is not one. It is a pricing decision embedded in the conversion itself.

This structure makes it nearly impossible to audit without independently sourcing the mid-market rate at the exact moment of each transaction and doing the comparison manually. For a finance team running payroll across multiple countries and currencies every month, that reconciliation is not realistic.

The result is that companies end up paying far more for cross-border payroll than they realize. When they eventually ask the right questions and do the math, the number is usually surprising. We hear this on calls regularly. A company reviews their FX costs for the first time and realizes the spread they have been absorbing adds up to tens of thousands of dollars a year.

What a Transparent FX Structure Actually Looks Like (With Numbers)

Transparency in FX means two things. The rate is disclosed. And it is listed as a line item on every invoice.

On Toku, the FX structure is straightforward. If you are paying out in stablecoins and your contractor wants stablecoins, there is no FX component at all. The only cost is 25 basis points, which is 0.25 percent, for the stablecoin-to-USD off-ramp if fiat conversion is needed. If the payout involves a currency conversion, the FX fee is contractually capped at 2.5 percent and typically runs between 1.5 and 2 percent. That rate appears as a line item on every invoice. There is no ambiguity about what you are paying for.

Here is what that looks like in practice. A company with 130 international contractors and approximately $1.1 million in annual payroll volume compared their costs between a widely used international payment service and Toku. Using the payment service's published rates for emerging market currencies, their annual cost came to roughly $25,000 in transfer and conversion fees alone. On Toku's structure, the equivalent FX cost came to approximately $16,400, plus a flat platform fee of $7,200 per year, for an all-in annual cost of around $23,600. The difference was meaningful. More importantly, the Toku number was predictable before the payments ran. The other number was not.

Toku also does not hold your funds. The platform integrates directly into your custodian or multisig and proposes transactions without ever taking custody. Your funds are not sitting in a Toku account earning yield between payroll runs. That is a structural choice, and it eliminates an entire category of revenue extraction that is standard at traditional providers.

How Does Stablecoin Payroll Eliminate the FX Problem?

The FX problem in global payroll exists because of currency conversion. When you fund payroll in USD and pay contractors in EUR, BRL, ZAR, or PHP, every transaction passes through a conversion layer that someone controls and profits from.

Stablecoin payroll does not eliminate conversion entirely. If your contractor wants to receive South African Rand in their local bank account, a conversion still has to happen. What stablecoin payroll eliminates is the hidden margin on that conversion and the float period during which your funds sit in someone else's account.

When you pay a contractor in USDC and they receive USDC, there is no conversion and no FX fee. The cost is 25 basis points for the off-ramp if they choose to convert to fiat at their end. That conversion happens at their direction, not yours, and the rate is transparent. When you fund payroll in USDC and a contractor needs local currency, the FX fee is disclosed upfront, capped contractually, and listed on the invoice.

This is not a theoretical benefit. It is a structural difference in how the money moves. Stablecoin rails were not designed around the float-and-margin model that traditional banking infrastructure runs on. The economics are different because the architecture is different.

Five Questions to Ask Your Current Provider About FX

These are the questions that prospects have asked on calls with us. They are the right questions to ask any payroll provider handling cross-border payments on your behalf.

What is your exact FX rate, and how does it compare to the mid-market rate at time of transaction?

You want a specific number, not a range. If the answer is "it depends," ask what it depends on and get a cap in writing.

Does FX appear as a separate line item on my invoice?

If the answer is no, ask where the FX margin goes and how you can verify the rate applied to each transaction. The absence of a line item is itself the answer.

Is your FX rate contractually capped?

Verbal quotes are not commitments. A contractual cap is the only protection that matters when rates vary by corridor and transaction size.

Do you hold my funds between funding and disbursement?

If yes, ask whether you earn any yield on those funds or whether the provider does. This determines whether you are paying an FX margin on top of a float benefit the provider is already capturing.

Can you show me the FX cost for last month's payroll run as a separate number?

If your provider cannot produce this number quickly, that tells you something about how the fee is structured and why it is not already visible on your invoices.

If you ask these questions and get clear, documented answers, you are working with a provider who is comfortable with transparency. If the answers are vague or the line items do not exist, you are probably paying more than you know.

Toku's Own Take on the Float Window Most Companies Never Think to Ask About

A Toku rep who spent four and a half years inside global payroll before joining described the model plainly on a call with a UAE and India gaming company: "I've worked in global payroll for about four and a half years and this is a big hot-button topic. You never actually see the line items on invoices. Sometimes the overcharges are up to 6%." The float and FX margin are not separate problems. They are the same revenue model running in sequence: hold the funds, earn yield, then extract FX margin on the way out. Neither step appears on an invoice.

The architectural alternative is non-custodial. Toku is added as a transaction proposer on the client's own custodian - Anchorage, Fireblocks, BitGo, or Ledger - not as a signatory. The funds never move to a Toku-controlled account. The platform proposes the transaction; the client's signers approve it; the payment goes directly to the contractor. There is no float window because there is no custody transfer. When a prospect on that same call asked point-blank whether there were any hidden extra fees - "that's basically what I'm trying to ask" - the answer was a contractually capped rate, listed as a line item, with no float extraction because the architecture doesn't permit it. That's the difference between a pricing policy and a structural guarantee.

The five questions in the section above are the questions prospects start asking once they understand the float-and-margin model. If your current provider cannot answer all five cleanly and in writing, you have your answer about where the margin is going.

The Math Is Worth Running

Most companies have never calculated their true FX cost in global payroll. Not because the number is hard to find, but because their provider never puts it on the invoice. The five questions above will tell you whether your current provider is transparent about FX or not. If they are not, running the numbers usually produces a figure that justifies the conversation.

Toku's FX fees are listed as line items on every invoice. Rates are contractually capped at 2.5 percent. Stablecoin-to-stablecoin payments carry no FX component. If you want to run the math on your current payroll costs, talk to the Toku team.
