The short version

  • Each has a real cost: 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.; 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.
  • They diverge on capability: Airbase covers Corporate cards, Carta covers Cap table of record.
  • Prices and features above were last checked on 30 August 2026.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
