The short version
- Only Airwallex has a free tier, so it costs nothing to try first.
- Each has a real cost: Airwallex airwallex is a licensed payments firm rather than a bank, so balances sit in safeguarding accounts at partner banks and are not covered by deposit guarantee schemes, which means a treasury policy that requires insured deposits cannot hold operating cash there.; Causal causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
- They diverge on capability: Airwallex covers Multi currency balances, Causal covers Variable-based modelling.
- 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.
Airwallex
- Airwallex is a licensed payments firm rather than a bank, so balances sit in safeguarding accounts at partner banks and are not covered by deposit guarantee schemes, which means a treasury policy that requires insured deposits cannot hold operating cash there.
- Available currencies, local account details, card programmes and product features differ by the entity you contract with, so a feature demonstrated to a customer in Australia or Singapore may simply not exist for the same company registered in another country.
- Onboarding is subject to compliance review and whole categories of business are declined or later offboarded, and because the account may hold operating cash, a compliance freeze during a review is a business interruption rather than an inconvenience.
- Foreign exchange is quoted as interbank plus a markup, which is cheaper than a high street bank but is still a spread that widens on less liquid pairs and on smaller amounts, so the saving assumed in the business case should be checked against the pairs you actually trade.
- Support is largely ticket and chat based with account management reserved for larger customers, so when a payment is stuck the resolution path is a queue rather than a named person, which is a poor fit for time critical settlement.
Causal
- Causal was acquired by Lucanet on 31 October 2024 and the independent brand has been retired in favour of Lucanet xP&A, so the roadmap, support and pricing you buy are Lucanet’s and not the ones the product built its reputation on.
- Self-serve pricing is gone: the old causal.app pricing page now redirects to a Lucanet solution page, so what was a transparent product you could sign up for is an enterprise sales conversation with no published rate.
- The variable-based model is a genuine departure from spreadsheet thinking, so an accountant fluent in Excel must relearn how to express a model, and the team members who could previously all edit the forecast often cannot at first.
- Deep Excel compatibility is limited by design; complex existing workbooks with macros, circular references or heavy lookups do not import cleanly and have to be rebuilt, which turns a tool evaluation into a modelling project.
- Consolidation, statutory reporting and multi-entity currency handling are weaker than in dedicated corporate performance management suites, so a group with several legal entities usually needs Lucanet’s other modules alongside it, raising the real cost well past the planning tool alone.

Answered from the vendors’ own pages
Airwallex: Is Airwallex a bank?
No. It holds payment institution, electronic money or equivalent licences in the markets it serves. Funds are safeguarded at partner banks rather than being deposits, and deposit insurance schemes do not apply.
Causal: Does Causal still exist?
The product does, as Lucanet xP&A. The independent Causal brand and self-serve offering have been retired following the October 2024 acquisition.
Airwallex: Can it replace my business bank account?
For many operating flows it can, but consider what you lose: no deposit protection, no lending relationship, no cash or cheque handling, and some counterparties and government bodies still expect a conventional bank account. Most users run it alongside a bank rather than instead of one.
Causal: What does it cost now?
Nothing is published. The former pricing page redirects to Lucanet, and the product is quoted as part of the Lucanet CFO Solution Platform.
Airwallex: Which countries can open an account?
It serves entities registered in a defined list of markets across Asia Pacific, Europe, the United Kingdom, the Middle East and North America, and the list changes. Check for your specific country of incorporation, because the answer determines both eligibility and feature set.
Causal: Can I import my existing Excel model?
Simple workbooks import. Models with macros, circular references or heavy lookup chains have to be rebuilt around named variables, which is the real migration cost.
Airwallex: Does it connect to my accounting software?
It integrates with the mainstream cloud ledgers so transactions feed through rather than being imported by hand. Confirm the integration covers all the currencies you hold, since multi currency handling in the ledger is a separate question.
Causal: Is it a replacement for a consolidation tool?
No. It plans and forecasts. Statutory consolidation and multi-entity reporting sit in Lucanet’s other modules.
Airwallex: How does the foreign exchange rate compare with a bank?
Materially better than a typical business bank's retail rate on major pairs, because it is quoted as interbank plus a stated markup. The gap narrows on thin currency pairs and small amounts, so test with your real volumes.
Airwallex: Are the cards accepted everywhere?
They are issued on the major networks and behave like ordinary company cards for most spend. Some merchants, particularly for deposits and car hire, treat prepaid style issuance differently, so do not assume parity with a bank credit card.
