The short version
- Each has a real cost: 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.; Medius the sourcing, contract and procurement modules are considerably less developed than the AP core, so buying Medius as a full source-to-pay suite means accepting weak upstream tooling.
- They diverge on capability: Dwolla covers ACH transfers, Medius covers Invoice capture and coding.

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.
Medius
- The sourcing, contract and procurement modules are considerably less developed than the AP core, so buying Medius as a full source-to-pay suite means accepting weak upstream tooling.
- Pricing is quote-only and driven by invoice volume, so a business with many low-value invoices pays disproportionately relative to the spend being controlled.
- Payments are billed on transaction volume separately from the AP subscription, which is easy to omit from a cost comparison against a licence-only AP tool.
- Private equity ownership since 2017 has produced an acquisition-driven product line, so payments and adjacent capability come from bought-in technology rather than the original platform.
- ERP integration depth varies sharply by system, and organisations on less common or heavily customised ERPs face integration work that lengthens the implementation.

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.
Medius: Is Medius a procurement suite or an AP tool?
Primarily an AP automation platform with procurement modules attached. If sourcing is your main requirement, look elsewhere.
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.
Medius: Who owns Medius?
Marlin Equity Partners, which acquired it in 2017 and has funded several bolt-on acquisitions since.
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.
Medius: How is it priced?
By quote, driven by invoice volume and entity count, with payments billed separately on transaction volume.
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.
Medius: Does it replace our ERP?
No. It sits alongside the ERP and posts approved invoices into it.
