Where each one falls short

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

Increase

  • The published per transaction rates exclude a monthly platform fee that Increase states varies by use case, so the transparent price page cannot produce a total cost and the material part of the deal is still negotiated privately.
  • Free allowances are deliberately small at ten account numbers and five physical cards, so any programme issuing accounts or cards at volume moves to quoted pricing almost immediately.
  • Banking is provided through partner banks, so programme approval, compliance obligations and the ability to launch at all depend on a bank relationship you do not control, and post-Synapse bank risk appetite has tightened considerably.
  • The API deliberately exposes payment rail mechanics rather than smoothing them, which is correct engineering but means a team without payments expertise will build reconciliation and return handling wrongly and only discover it when funds go astray.
  • Coverage is United States only, so a company with international payout needs runs a second provider and reconciles two ledgers, and the single API argument disappears at the first cross border customer.

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

Increase: Does Increase publish its pricing?

Partly. Per transaction fees for ACH, wires, RTP, FedNow and cards are listed publicly. The monthly platform fee is not, and it is described only as varying by use case.

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.

Increase: Who holds the deposits?

Partner banks, not Increase itself. That relationship determines your programme approval, your compliance obligations and your risk if the bank changes appetite.

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.

Increase: Is it international?

No. Increase covers United States rails only, so cross border payouts require a second provider.

Modern Treasury: Which rails are supported?

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

Increase: How is it different from a middleware BaaS platform?

It exposes the rails rather than abstracting them, showing real return codes and settlement timing. That suits teams who understand payments and punishes teams who do not.

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.
