- They diverge on capability: Dwolla covers ACH transfers, Formance covers Double-entry ledger.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Dwolla
- Nothing is published: there are no per-transaction rates, no platform fee and no minimum on the pricing page, so every buyer negotiates blind and small platforms have no way to sanity check what they are quoted.
- It is payments only, with no deposit accounts, card issuing or general ledger, so companies embedding financial products need at least one further vendor and the reconciliation between them.
- Instant payment reach depends on the receiving institution supporting RTP or FedNow, so a meaningful share of payouts still fall back to ACH timing regardless of what the API can do.
- ACH returns and administrative returns remain your operational problem, and platforms new to bank rails routinely underestimate the customer support load that failed debits generate.
- Access to instant rails runs through Dwolla banking partner, which reintroduces a bank dependency into a product that otherwise avoids sponsor bank programme risk.
Formance
- Formance holds no money and provides no regulatory cover, so it must be paired with a payments provider or bank, and buyers occasionally mistake a ledger for a treasury system and discover the gap late.
- Numscript is a domain-specific language your team must learn, and while it makes complex splits expressible it also means transaction logic sits outside the languages your engineers already debug well.
- Self-hosting a ledger that must never lose or duplicate a transaction is a serious operational commitment covering backups, upgrades and Postgres tuning, which is real cost the zero licence fee hides.
- Enterprise pricing is not published, so the difference between the free path and the supported path cannot be evaluated without a sales conversation.
- The company is much smaller than the incumbent alternatives, and while the MIT licence protects the code it does not protect the roadmap, so features on the hosted side may arrive slowly or change direction.

Answered from the vendors’ own pages
Dwolla: What does Dwolla cost?
It does not publish anything. Pricing is custom and built around volume, rails and integration. Establish the monthly platform fee and any minimum before negotiating per-transaction rates.
Formance: Is Formance really open source?
Yes. The core ledger is MIT licensed with full source access and no deployment restrictions.
Dwolla: Does it support instant payments?
Yes, through both the RTP network and the FedNow Service, with automatic selection based on the receiving bank. Where neither is supported, payments fall back to ACH.
Formance: Does Formance move money?
No. It records and orchestrates movements; the actual payments happen at a PSP or bank you connect.
Dwolla: Is Dwolla a bank?
No. It is a payments platform that works through banking partners. It does not offer deposit accounts or card issuing.
Formance: What does the enterprise version cost?
Not published. It is an annual subscription quoted per customer.
Dwolla: How does bank account verification work?
Either instantly through open banking connections or by micro-deposit verification, which takes a day or two but works where instant linking fails.
Formance: Do I have to use Numscript?
Yes for anything beyond the simplest transfers. It is how multi-party transactions are expressed atomically.
