Melio
What we loved & hated.
From hands-on testing across real businesses. The good, the bad, and the deal-breakers.
Airwallex
Pros
- 0.5% FX markup on major currencies — vs 2–3% at most banks; on $100K/month in international payments, that's $1,500–$2,500 saved monthly.
- Local bank accounts in 20+ currencies — receive USD, EUR, GBP, AUD, SGD, and more as if you had a local entity.
- Free local payouts in 120+ countries — most international transfers are free when routing through local payment rails.
- Zero incoming payment fees — collect international payments without deduction, except Korean Won (0.6% regulatory fee).
- No FX markup on like-for-like international card settlements — receive what was charged without currency conversion loss.
Cons
- SWIFT transfers cost $15–$25 each — not all international transfers qualify for free local rails.
- Explore plan is conditionally free — requires $5,000/month deposit or $10,000 maintained balance to avoid fees.
- Not an AP automation tool — no approval workflows, no credit card float for US domestic vendors, no 1099 automation.
- International card acceptance at 3.40% + $0.30 — not the cheapest option for high-volume card payments.
- No domestic US bill pay features — Melio's ACH-by-credit-card capability does not exist in Airwallex.
Melio
Pros
- Pay any vendor by credit card — even vendors who accept only checks or ACH; Melio routes the credit payment as ACH or check to the recipient.
- Earn credit card rewards on all AP spend — vendor payments, rent, insurance, and subscriptions all generate points or cashback.
- Free Go plan — 5 ACH payments/month, credit card payments, and QuickBooks/Xero sync at $0.
- Flat Core plan at $25/month — unlimited users on Core and above; cheaper than per-seat AP tools for any team of 2+.
- W-9 and 1099 automation on Core and above — contractor tax compliance built into the AP workflow.
Cons
- Credit card payments cost 2.9% — paying $10,000 in vendor invoices by card costs $290; only worthwhile if rewards exceed the fee.
- ACH caps on lower plans — Go gets 5 free/month, Core gets 20, Boost gets 50; high-volume users pay $0.50 per additional transfer.
- US-centric — no multi-currency accounts, no FX management, no international payment infrastructure.
- No AI invoice coding or purchase orders — less suited to complex AP workflows than enterprise alternatives.
- Phone support only on Boost and above — Core plan users limited to priority chat.
Both tools move money to vendors. They solve completely different payment problem — choose by geography and whether credit card float matters.
Airwallex is the right pick the moment international payments are material to your business. At 0.5% FX markup versus the 2–3% typical at banks and Stripe, a business moving $50,000/month across currencies saves $750–$1,250 per month on Airwallex — that pays for many years of subscription. Local bank details in 20+ currencies and free local payouts in 120+ countries are genuinely useful infrastructure for ecommerce sellers, agencies with overseas clients, and any business with a global supply chain.
Melio wins for US domestic AP, and specifically for one feature no competitor matches: paying any vendor by credit card regardless of how they accept payment. The 2.9% credit card fee is only worthwhile if your rewards rate exceeds it — but for a business running $50,000/month in vendor payments on a 3% cashback card, the net is $50/month positive. The free Go plan with QuickBooks/Xero sync is legitimate value for low-volume businesses who just want clean AP records without a subscription.
The overlap is narrow: a US business with occasional international supplier payments. For that use case, Airwallex handles the FX side and Melio handles the domestic side — many companies use both without conflict.
