Airwallex Billing

Airwallex Billing is a billing and collections platform for businesses that invoice internationally or combine subscriptions with usage-based charges. It is best suited to teams that need broad payment coverage and already work with Airwallex Payments or compatible accounting tools. Its billing range and automation are useful strengths; transaction-based fees and basic checkout customization are important trade-offs.

Overview

Airwallex brings invoicing, recurring subscriptions and usage-based pricing into one global payments platform. Its flat-fee, tiered, pay-as-you-go and hybrid models can accommodate different ways of charging without limiting a business to standard recurring plans. Billing in 130+ currencies and collection through 160+ global and local payment methods make it a natural fit for cross-border operations.

Teams can manage products, pricing, invoices and subscriptions in a web app without code, or use APIs and webhooks to build custom integrations and workflows. That flexibility serves both operational teams and developers, but checkout customization is basic, so businesses that need a highly tailored payment experience may need another approach.

Key features

Billing and payment recovery

Invoice sending, reminders, failed-payment retries and payment reconciliation can reduce routine billing follow-up. Teams can control retry schedules, use recovery workflows and notify customers by email. QR code sharing adds another way to prompt payment. These tools provide useful recovery structure, though notification channels are limited to email.

Subscription Management supports free trials and pricing discounts, while usage-based billing can charge according to actual customer usage. Recurring payments are marked as unsupported in the payment-recovery feature set, so businesses should distinguish that limitation from the broader subscription-management offering before choosing it for a specific workflow.

Tax and integrations

Tax automation calculates GST, VAT and sales tax using customer location and product category, helping reduce manual tax calculations across markets. Accounting integrations include Xero, QuickBooks, NetSuite, Microsoft Dynamics 365 Business Central, Odoo and Sage. Airwallex Payments, Xero and NetSuite are also listed among payment integrations, giving businesses already using those services a more direct fit.

Security and support

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. The range can serve both self-directed teams and businesses that need implementation help.

Pricing

Airwallex uses a freemium model, with invoicing free and usage-based and subscription billing charged per successful transaction. The plan terms are:

• Invoicing: free. Create and send invoices globally; a strong starting point for businesses that need invoicing without adding a subscription charge.
• Usage-based Billing: $0.50, paid once, billed per successful transaction. This is for charging customers by actual usage; transaction volume therefore matters to the cost.
• Subscription Management: $0.50, paid once, billed per successful transaction. It automates recurring revenue, but the per-successful-transaction charge should be weighed against expected payment volume.

The free invoicing plan avoids a plan fee but does not make usage-based or subscription billing free. No seat allowance, trial length or renewal term is given for these plans, so businesses comparing costs should focus on the successful-transaction fees that apply to paid billing models.

Platforms

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

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 most compelling for companies combining international invoicing, varied pricing models and payment recovery, especially where Airwallex Payments or its accounting integrations are already part of the operation. A business that needs extensive checkout control or relies on recurring payments in the recovery feature set should look carefully at alternatives.

Pros and cons

• Con: Email is the notification channel, and recurring payments are marked unsupported in the payment-recovery feature set.

Alternatives

Kill Bill is worth considering for teams that want an open-source core and self-hosted control over infrastructure and data; its listed platform support also spans API, web and desktop systems. Lago offers a free AGPLv3-licensed self-hosted option, with custom pricing for Lago Premium, making it an alternative for teams comparing open-source deployment paths.

NovaBilling has a free self-hosted Community plan with unlimited tenants and customers, all six payment providers and GitHub community support. Pabbly Subscriptions may suit businesses whose needs fit its free plan of up to 50 customers, with revenue limited and team members and the affiliate module excluded.

UniBee provides a free, self-hosted and customizable open-source plan, but it requires manual setup and community support. Flexprice is a relevant alternative for teams that can work within its free-plan caps of 100k events per month and up to $100K in cumulative billing revenue.

WooCommerce offers free self-hosted core software with unlimited products, orders and APIs, making it a different option for businesses whose needs fit that model. Zuora CPQ uses custom pricing based on factors including transaction volume, regions and implementation needs, so it is an alternative for businesses seeking a tailored commercial arrangement.

Verdict

Choose Airwallex Billing if your business needs international invoicing, several billing models and automated collection workflows in one platform, particularly if Airwallex Payments or its accounting integrations are already in use. Its strongest case is the combination of global reach and billing automation; look elsewhere if per-transaction costs, basic checkout customization or the stated recurring-payment limitation conflict with your payment model.
