The short version

  • Each has a real cost: 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.; Paperbell it only models packaged session based work, so anyone selling project scoped deliverables will find the proposal side too rigid to use.
  • They diverge on capability: Modern Treasury covers Multi-rail payment initiation, Paperbell covers Package based offers.
  • 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.

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.

Paperbell

  • It only models packaged session based work, so anyone selling project scoped deliverables will find the proposal side too rigid to use.
  • There is no time tracking, project management or task system, so any work between sessions is managed somewhere else entirely.
  • Payments run through a third party gateway, so the card processing fee applies on top of the subscription and is easy to leave out of a comparison.
  • The flat account price is attractive at scale but poor value for a coach with two or three clients, who is subsidising capacity they do not use.
  • Customisation of the client facing pages is limited, so a coach with a strong brand will find the purchase flow looks like every other Paperbell account.

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.

Paperbell: Is it priced per client?

No. It is a flat account price with unlimited clients, which is unusual in this category and is the main economic argument for it.

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.

Paperbell: Does it take a cut of my payments?

The card processor takes its standard fee. Confirm the current subscription price with the vendor and model the processing fee separately.

Modern Treasury: Which rails are supported?

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

Paperbell: Can I use it for project work?

Not well. It is built around packages of sessions, and project scoped proposals do not fit that shape.

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.

Paperbell: Do I still need a scheduling tool?

No. Scheduling is built in, and replacing a separate scheduling subscription is part of the cost case.

Paperbell: Can I brand the client pages?

Only lightly. Deep brand customisation is not available.
