Airwallex Billing

Airwallex Billing brings invoicing, subscriptions and usage-based charges together for businesses selling across borders. It is best suited to teams that need several billing models and international collection; its broad reach and billing automation are balanced by per-transaction fees and basic checkout customization.

Overview

Flat-fee, tiered, pay-as-you-go and hybrid billing let businesses charge for products in different ways within one platform. Airwallex says customers can bill in 130+ currencies and collect through 160+ global and local payment methods, a useful scope for companies serving multiple markets. It does not, by itself, make the platform the right fit for every payment mix.

Teams can manage products, pricing, invoices and subscriptions in the web app without code, or use APIs and webhooks to build custom integrations and workflows. That combination suits both operational users and developers, while basic checkout customization may fall short for businesses that need close control over the payment experience.

Key features

Billing operations and recovery

Airwallex can send invoices, issue reminders, retry failed payments and reconcile incoming payments with ERP and accounting software. Retry schedule controls, recovery workflows and email notifications give teams ways to organize follow-up rather than leaving every failed payment to manual attention. QR code sharing provides another route for customers to pay.

Subscription Management supports free trials and pricing discounts. The plan’s transaction charge means those capabilities should be weighed against the volume of successful transactions, especially for businesses with frequent recurring payments.

Tax, integrations and security

Tax automation calculates GST, VAT and sales tax based on customer location and product category, helping businesses manage common cross-market tax calculations. Accounting integrations include Xero, QuickBooks, NetSuite, Microsoft Dynamics 365 Business Central, Odoo and Sage. Payment integrations include Airwallex Payments, Xero and NetSuite.

Airwallex says it is PCI DSS Level 1 and SOC 2 Type II certified, encrypts data in transit and at rest, and requires two-factor authentication. Support options include help centre articles and FAQs, email support, dedicated account management, onboarding support and custom API implementation.

Pricing

Airwallex Billing has a free plan and paid billing options charged per successful transaction, rather than a published monthly subscription price for these billing models. That structure can suit businesses whose billing volumes are modest or variable, but transaction costs rise with successful payment volume.

• Invoicing: free. It lets businesses create and send invoices globally, making it the entry point for teams focused on invoicing rather than usage-based or subscription billing.
• Usage-based Billing: $0.50, paid once, billed per successful transaction. It fits businesses charging customers according to actual usage; transaction frequency matters when estimating cost.
• Subscription Management: $0.50, paid once, billed per successful transaction. It adds recurring-revenue automation, with support for trials and discounts, but is less attractive when transaction charges outweigh the value of that automation.

The free invoicing option provides a way to send invoices without the listed charge for that plan. The paid options are not priced as flat monthly tiers, so compare their transaction fees against expected successful payments before choosing a billing model.

Platforms

Airwallex Billing is available through a web app and API. The web app supports no-code management of products, pricing, invoices and subscriptions; API access and webhooks suit custom workflows and integrations.

Who it's for

Airwallex describes Billing as built for global businesses, with onboarding guidance spanning product-led startups through sales-led enterprises. It is a strong fit for companies combining international invoicing with varied charges and payment recovery, particularly those already using Airwallex Payments or its accounting integrations. Businesses needing highly tailored checkout design or a simple fixed recurring fee should weigh the limitations and transaction-based pricing carefully.

Pros and cons

• Broad international collection: Support for 130+ currencies and 160+ payment methods gives cross-border businesses a wide collection footprint.
• Flexible billing models: Flat-fee, tiered, pay-as-you-go and hybrid approaches accommodate more than fixed subscriptions alone.
• Automated billing follow-up: Invoice sending, reminders, retries and reconciliation can reduce routine collection work.
• Transaction-based paid plans: The $0.50 per successful transaction charges scale with payments, which may make costs less predictable than a flat fee.
• Basic checkout customization: Businesses needing a more tailored checkout experience may find the controls insufficient.

Verdict

Choose Airwallex Billing if your business needs international collection, multiple billing models and automated invoice and payment recovery in one platform. Its range and operational automation are the main reasons to choose it; transaction-based charges and basic checkout customization are the main reasons to look elsewhere.
