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.

Vertex

  • Pricing is entirely custom and not published, requiring a sales engagement to get a quote.
  • The platform is built for enterprise-scale tax complexity, which can be more than small businesses need.
  • Implementation typically requires integration work with existing ERP systems, adding setup time and cost.
  • Documentation on self-serve plan tiers or limits is not publicly available, unlike simpler tax tools.

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.

Vertex: Is Vertex's tax software pricing publicly available?

No. Vertex does not publish pricing for its Vertex Cloud or enterprise tax platform; costs are determined through a custom quote based on modules, transaction volume, and deployment scope.

Source
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.

Vertex: Roughly what do businesses pay for Vertex?

As reported by third-party buyer guides, not Vertex itself, mid-market companies processing 10,000-50,000 monthly transactions often pay in the $40,000-$100,000 per year range including platform and transaction fees.

Source
Modern Treasury: Which rails are supported?

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

Vertex: Who manages Vertex Cloud after it's set up?

With the Vertex Cloud deployment option, ongoing operations such as monitoring, configuration, and state tax correspondence remain the responsibility of the customer's internal team rather than Vertex.

Source
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.

Vertex: What systems does Vertex integrate with?

Vertex integrates with major ERP and e-commerce platforms including SAP, Oracle, Microsoft, Shopify, Workday, and NetSuite to embed real-time indirect tax calculation into existing business systems.

Source
