The short version

  • Each has a real cost: Carta pricing scales with the number of stakeholders on the cap table, so a company that grants options broadly pays a rising annual fee for employees and small angels who sign in once a year, and the cost keeps climbing after the round that justified it is spent.; 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.
  • They diverge on capability: Carta covers Cap table of record, Modern Treasury covers Multi-rail payment initiation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Carta

  • Pricing scales with the number of stakeholders on the cap table, so a company that grants options broadly pays a rising annual fee for employees and small angels who sign in once a year, and the cost keeps climbing after the round that justified it is spent.
  • The cap table is a legal record assembled from years of board consents, so migrating to another provider means re-entering historical transactions and having counsel confirm the rebuilt table matches the signed documents, which is why most companies stay whatever they think of the service.
  • The product is built around United States company law and tax practice, Delaware entities, 409A and ASC 718, so a company incorporated in the United Kingdom, Europe or elsewhere gets a record keeping tool while the valuation and compliance features that carry the price are of limited or no use.
  • 409A valuations are delivered on a cadence and require a refresh after each material event or every twelve months, so a company that raises or changes materially is repeatedly back in a valuation process with fees and turnaround time attached, and a late valuation blocks option issuance.
  • Carta drew sustained criticism in 2024 over how customer cap table data intersected with its secondary trading business, and although it exited that activity the episode is a live reason to check what a vendor holding your ownership record is permitted to do with it.

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

Carta: Do I need Carta before I have employees with options?

No. Before options exist a spreadsheet reviewed by your lawyer is usually enough. The pressure to move normally comes at a priced round, or the first time you need a 409A to set a strike price.

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.

Carta: Is the 409A included in the subscription?

The subscription tiers bundle valuations differently and refreshes after material events can carry additional cost. Check what triggers a chargeable revaluation before you sign, because raising a round is exactly the moment you will need one.

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.

Carta: Can my accountant get the stock compensation numbers out of it?

Yes, it produces ASC 718 expense schedules and exports. If your accounts are prepared under a different framework, expect the schedules to be a starting point that your accountant reworks rather than something they post directly.

Modern Treasury: Which rails are supported?

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

Carta: Is it useful for a company outside the United States?

It can hold the share register and grants, and it does support some non United States structures. The 409A and United States tax workflow will not apply to you, so weigh it against local alternatives that understand your filings.

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.

Carta: How hard is it to leave?

Harder than the export button suggests. You can export the data, but the receiving system has to reproduce every historical grant, cancellation and transfer, and someone has to verify the result against the original signed consents.

Carta: Who normally pays for it, the company or the investors?

The company, even though investors and counsel are frequent users. That is the usual complaint about the pricing model: the party paying is not the only party benefiting.
