The short version

  • Only Yapily has a free tier, so it costs nothing to try first.
  • 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.; Yapily production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
  • They diverge on capability: Modern Treasury covers Multi-rail payment initiation, Yapily covers Unified open banking API.
  • 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.

Yapily

  • Production pricing itself is not published; only the resulting typical merchant transaction cost is publicly known, so the underlying platform fee still requires a sales conversation.
  • Consumer adoption of pay-by-bank still lags card payments, so merchants offering it as a checkout option typically see it used as a secondary rather than primary payment method.
  • Coverage depends on the banks in each country maintaining reliable open banking APIs, and inconsistent bank-side reliability across markets is a known category-wide weakness, not unique to Yapily but not solved by it either.
  • As infrastructure for both account data and payments, a company only needing one of those two capabilities is still evaluating a broader platform than it may need.
  • Regulatory dependence on PSD2 and UK open banking rules means the underlying legal framework, not just Yapily's product, could shift and affect what is possible on the platform.

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.

Yapily: Is there a free way to try it?

Yes, sandbox access is free for development and testing.

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.

Yapily: How much cheaper is pay-by-bank than card payments?

Typically 0.1 to 0.5% of transaction value, or a flat 5 to 30 pence, against 1.5 to 3.5% for card scheme fees.

Modern Treasury: Which rails are supported?

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

Yapily: Is production pricing published?

No, production access is pay-as-you-go but exact rates require a sales conversation.

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.
