Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Medius Expense
- The Expensya name is being retired, so contracts, logins and support articles change identity mid-relationship and internal documentation has to be rewritten.
- It is now a module inside an accounts payable suite, so expense-specific roadmap items compete with supplier invoice work for engineering time.
- Pricing is not published and is discounted against bundling with Medius AP, which makes standalone expense quotes less competitive than they look.
- Strength is concentrated in Europe and the Maghreb; North American and Asian tax and mileage handling are thinner than the European coverage.
- It does not issue cards, so real-time spend controls are absent and it relies on card feed reconciliation after the fact.
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.

Answered from the vendors’ own pages
Medius Expense: Is Expensya still available?
Under that name, no. The product continues as Medius Expense, with the branding cutover on 30 September 2026 and no change to features or data.
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.
Medius Expense: Do I have to buy Medius AP as well?
No, but the commercial terms improve materially if you do, which is worth testing during negotiation.
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.
Medius Expense: Does it issue corporate cards?
No. It reconciles existing card feeds rather than issuing its own cards.
Modern Treasury: Which rails are supported?
ACH, wires, RTP, FedNow, push to card, cheques and stablecoin payments, subject to what your bank supports.
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.
