Where each one falls short

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

Airbase

  • Card issuing and bill payment are built around United States entities and United States bank accounts, so a group with subsidiaries abroad keeps running local card and payment processes alongside and does not get the single ledger of spend that justified the purchase.
  • The value depends on nearly all spend flowing through the platform, which makes partial adoption almost worthless and means the rollout is a change management exercise across every budget holder rather than a finance department deployment.
  • Paylocity's acquisition in 2024 reorients the roadmap towards a human capital management suite, so expense reimbursement is likely to be well served while procurement and the more finance specific features compete for attention with payroll and HR priorities.
  • Pricing combines a platform fee with tiering on features and users, and part of the economics rests on interchange rebates from card spend, so a company that puts most of its spend on transfers rather than cards pays the fee without earning the offset.
  • The general ledger sync is a mapping you own, so a chart of accounts change, a new department dimension or a ledger migration means reworking the coding rules, and a bad mapping quietly posts correct approvals to the wrong accounts.

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

Airbase: Does it work for companies outside the United States?

Partially. Some international spend and reimbursement is supported, but card issuing and the payment rails are strongest for United States entities. Confirm coverage for each country you operate in before assuming it replaces local processes.

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.

Airbase: Does Airbase replace our accounting system?

No. It manages spend and pushes coded transactions into the ledger. QuickBooks, NetSuite or whatever else you use stays.

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.

Airbase: What changed after the Paylocity acquisition?

Ownership and roadmap direction. The product continues, now positioned alongside Paylocity's payroll and HR products. If procurement is your main reason to buy, ask directly about investment in that module.

Modern Treasury: Which rails are supported?

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

Airbase: How is it priced?

A platform subscription with tiers, plus usage and user dimensions, partly offset by rebates on card spend. Because the rebate depends on card volume, model your own mix of card versus transfer spend before accepting a payback figure.

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.

Airbase: Can we use it for accounts payable only?

You can, but the approval consistency argument weakens considerably. Most of the reported benefit comes from cards, bills and reimbursements sharing one policy and one coding process.

Airbase: Will our auditors accept the approval records?

The per transaction record of approver, receipt and coding is generally what auditors want to see for spend testing. Agree the sampling approach with them early, particularly around any spend that still happens outside the platform.
