Wallester vs Airwallex: Card Control or Cheap Currency?

These two names appear on the same shortlists constantly, which is odd, because they are barely competitors. One issues cards. The other holds currency. Confusing them is how businesses end up paying a 2% conversion cost on spending that never needed to touch a card at all.

The one-line difference

Wallester Business is a card-issuing platform. You fund a balance and create virtual and physical Visa cards with individual limits. Its published Free plan includes "300 virtual cards included" at "€0 /month", with "Unlimited physical card issuance".

Airwallex is a multi-currency account. You receive, hold and convert money in many currencies, with cards as one feature among several. Its pricing page describes "Accounts with local bank details in 20+ currencies".

Both figures read from each vendor's own pricing page on 9 August 2026.

Where the money actually goes

The gap that matters is the conversion line, and it is not close. On €50,000 of foreign-currency spending, a 2% markup costs roughly €1,000; at 0.5% it costs roughly €250. That difference is larger than most of the software either platform replaces.

So which problem do you have?

If your problem is control, Wallester wins and the FX gap may not matter. A business whose spend is mostly domestic, with fifteen subscriptions on one shared card number and no clean way to attribute anything, has a control problem. Issuing a card per vendor with a per-card ceiling solves it directly, and 300 free cards means you never ration them. Read our Wallester review for the full pricing picture and the setup walkthrough for what configuring it looks like.

If your problem is currency, Airwallex wins outright and the card allowance is beside the point. A business invoicing in three currencies and converting each one back through a bank is losing money at the conversion step, and no amount of card control recovers it. Local bank details mean a US client pays your US details as a domestic transfer — no conversion, no correspondent chain. Our Airwallex review covers the mechanism, and which currencies you can actually be paid in covers the important limit on that promise.

If you have both problems, run both. Hold and convert with Airwallex, issue controlled cards with Wallester, and fund the second from the first. This is the normal shape of a cross-border finance stack and it costs nothing extra, because both entry tiers are free.

The security argument, which is not about money

There is a second reason the split matters, and it rarely appears in comparisons because it does not show up in a fee table.

A card-issuing platform lets you give every vendor its own number. When one of those numbers leaks — and over enough years one will — the blast radius is a single subscription. You cancel that card, reissue it, and nothing else in the business notices. Compare that with the common arrangement where one card number is shared across every recurring payment: a single compromise means re-entering card details at every vendor you use, usually under time pressure, usually while some of them are failing.

A multi-currency account does not solve that, because issuing many disposable cards is not what it is for. And a card platform does not solve your FX, because holding currency cheaply is not what it is for. The reason to run both is that each one's weakness is the other's entire product.

The mistake to avoid

The expensive error is picking the card platform because the card offer is generous, then running foreign spend through it. Free cards are a real benefit; they are not worth 1.5 percentage points on every foreign transaction. Work out roughly what share of your spend leaves your home currency before you decide — if it is above about a fifth, the conversion line dominates every other difference on this page.

The reverse mistake is rarer but real: choosing the multi-currency account and then trying to run twenty subscriptions off two card numbers because issuance is not its strength. That is a control problem you will feel every month at reconciliation.

A worked example

Take a ten-person agency billing €600,000 a year, of which €150,000 of costs are paid in foreign currencies, running about forty vendor subscriptions.

On Wallester alone: the cards are free and the control problem is solved outright — forty subscriptions, forty cards, forty ceilings. The €150,000 of foreign spend converts at Visa rate plus 2%, costing roughly €3,000 a year.

On Airwallex alone: the same €150,000 converts at 0.5% on major pairs, costing roughly €750 — a saving of about €2,250. But the forty subscriptions are now sharing far fewer card numbers, so a compromised card disrupts more than one vendor and attribution at month end is manual work someone has to do.

Running both: cards from Wallester at €0 a month, currency through Airwallex at 0.5%, and the agency keeps roughly €2,250 a year while retaining per-vendor isolation. The figures are illustrative and your own pairs will differ, but the shape of the answer does not — the two costs are independent, so optimising them separately beats compromising on either.

What neither of them is

Neither is a credit product. Both draw on money you already have, so neither helps with the gap between paying suppliers and being paid by clients — that is what a business credit line or a charge card is for, and corporate card vs business card sets out the real differences. Neither is a bank in the sense of deposit protection, either; check how client funds are held and safeguarded before you park a large balance in either one.
