The short version

  • Each has a real cost: Modern Treasury you must already have or be able to obtain your own bank accounts with the right connectivity, so early stage companies without a banking relationship cannot use it and are pushed towards a sponsor bank model instead.; Soldo cards are prepaid, so if the central wallet runs low the cards decline in front of a supplier, and treasury has to keep an idle float funded rather than using a credit line.
  • They diverge on capability: Modern Treasury covers Multi-rail payment initiation, Soldo covers Prepaid company cards.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Modern Treasury

  • You must already have or be able to obtain your own bank accounts with the right connectivity, so early stage companies without a banking relationship cannot use it and are pushed towards a sponsor bank model instead.
  • Pricing rests on an annual minimum commitment, and companies that miss their volume forecast pay the minimum regardless, which makes the headline per-transaction rate close to irrelevant in year one.
  • Supported bank connectivity is a finite list, so if your bank is not on it you are either waiting for an integration or changing banks, which is a far larger project than adopting the software.
  • It is software over banking, not banking, so it does not solve card issuing, deposit accounts or the licensing questions that a company embedding financial products still has to answer elsewhere.
  • The ledger is genuinely good but adopting it properly means making it the source of truth for balances in your product, which is a significant application change rather than a payments integration and is where implementations run long.

Soldo

  • Cards are prepaid, so if the central wallet runs low the cards decline in front of a supplier, and treasury has to keep an idle float funded rather than using a credit line.
  • The plan fee covers only three users, and per-user charges plus physical card fees mean the real monthly cost is several times the advertised headline for a team of twenty.
  • It does not extend credit, so it gives no working capital benefit and no card rewards of the kind US charge card issuers use to offset their cost.
  • Sole traders and some business types are not accepted, which catches out small consultancies expecting to sign up online.
  • Coverage is European; a company with US or Asian subsidiaries will need a second card programme and a second expense workflow for them.

Answered from the vendors’ own pages

Modern Treasury: Is Modern Treasury a bank or a banking as a service provider?

Neither. You hold your own bank accounts and it is software over them. That avoids sponsor bank concentration risk but means you need the bank relationship yourself.

Soldo: Is Soldo a credit card?

No. It is prepaid electronic money. You fund a wallet and cards spend from it, so there is no credit line and no interest-free period.

Modern Treasury: What does it cost?

Not published. A platform access fee plus usage fees across rails, on an annual term with a single minimum commitment. Negotiate the minimum, not the per-transaction rate.

Soldo: What licence does Soldo hold?

Soldo is authorised as an electronic money institution, including UK, Irish and Italian entities, which is why it can issue cards without a sponsor bank in those markets.

Modern Treasury: Which rails are supported?

ACH, wires, RTP, FedNow, push to card, cheques and stablecoin payments, subject to what your bank supports.

Soldo: What does it really cost for twenty users?

Take the plan fee, add the per-user rate for the seventeen users beyond the included three, then add card issuance fees per physical card.

Modern Treasury: Do we still need our own compliance programme?

Yes. KYB, KYC and transaction monitoring are included in the platform, but you are the one holding the accounts and the regulatory obligation sits with you and your bank.
