Overview of Scale

Learn how to use Scale, our solution for any business that needs to transact with multiple counterparties. Scale allows you to establish transactional relationships between yourself and your subsidiaries, business partners and clients, utilising a single platform to efficiently receive, convert and move funds.

Traditionally, transaction clearing between trading entities is limited by the efficiency of the underlying banking system. International collection and payout, particularly involving currency exchange, often incur unreasonable fees and charges, further plaqued by lengthy processing delays.

With Scale, your platform account and the counterparty accounts can be grouped together in the same ecosystem, allowing for quick fund transfers and efficient reconciliation between parties. Airwallex's feature-rich APIs allow platform customers to focus on building innovative business models, while improving operational efficiency and optimising fund management involving multiple currencies.

You can tailor your Scale experience according to your business requirements, including:

  • Registering your subsidiaries, business partners and clients for Airwallex accounts to get a set of capability required to facilitate your business transactions
  • Connecting your Airwallex account to another Airwallex account and defining the nature of this connection
  • Specifying how funds move from your account to the connected Airwallex account and vice versa.

Register as a platform and create your platform account by submitting your business information via the online sign up form or by contacting us directly. Once your platform account is activated, you can start creating Airwallex accounts for your subsidiaries, business partners and customers via our API. Alternatively, Airwallex accounts can be created independently by your counterparties and subsequently connected to your platform account.

Define your Scale experience by determining the way you want to transact with your counterparties.

You can create a counterparty account via API by submitting the required information and documentation. Once a counterparty account is created, it will be connected to your platform account and your platform can carry out actions on behalf of the connected account in line with the authorisations provided, such as:

  • Account debits for the purpose of processing fees and charges
  • Account credits to pay commissions, proceeds of sale or refunds
  • Performing payments and withdrawals
  • Converting from one currency to another
  • Querying balances and transactional history including payment history, conversion history and deposit history

Case study - Marketplace platform

As a marketplace, you have merchants offering their goods or services on your platform. Use Scale to onboard your merchants into the Airwallex ecosystem allowing them to immediately receive sales proceeds, convert from sale currency to their home currency and withdraw to their bank account. Merchants may tap into these functionalities directly through Airwallex’s web portal, or you can simply adopt our API solution to merge our components into your user interface, allowing your merchants to indirectly access all of our product features.

Scale provides a complete set of customized solutions for you and your merchants. With Airwallex's flexible account system, the platform enables transparent management of end-to-end capital flows, while merchants have more control over collections, exchanges, and capital flows between virtual wallets and physical accounts. Scale unifies the management of transactions done via fragmented online and offline channels.

Scale is a comprehensive wallet solution built on top of our collection, FX conversion and global payments infrastructure, allowing you and your merchants to conduct pay-in, pay-out, funds conversion and view multi-currency wallet balances in one system. It also allows you to credit sale proceeds and charge fees from your merchants’ wallets in real-time (subject to the arrangements between you and your merchants).

Scale empowers marketplaces by supporting onboarding, establishing connections between accounts and real-time fund transfers at scale via API, seamlessly integrating the following processes:

  • Onboarding: Register merchants, suppliers and other entities onto the Airwallex network via API, with an optional express KYC process;
  • Connect: Establish connections between marketplace accounts to newly onboarded merchant accounts and automatically define the nature and operational rules of such connections (e.g. by default, platform is authorised to debit merchant’s account for fees, etc);
  • Transfer: Facilitate pay-in / pay-out transactions as per the agreements between platform and merchants, and take full advantage of Airwallex’s Collection / FX / Payment capabilities.

Scale from the marketplace's perspective

Scale is built and designed to support marketplaces’ requirements to process large volumes of transactions across multiple jurisdictions and currencies. Once merchants are onboarded, the system defines authorized relationships between the marketplace and merchants’ accounts, enabling real-time transaction functionality and wallet transfers to simplify settlement.

These real-time funds transfers are requested via an API and may include:

  • Account debit from merchants for processing charges and fees and sales refunds
  • Account credit to merchants for sales proceeds
  • Initiate wallet-to-wallet transfers between merchant accounts
  • Query balances and transactions history

Airwallex will be able to create merchant accounts and global accounts for merchants through an API.

Scale from merchant's perspective

Once an Airwallex account is created for the merchant, the merchant will have access to a multi-currency wallet that records and displays all transactional activities within the Airwallex system, and can be provisioned a global account that acts as a collection and disbursement portal to external bank accounts from our integrated bank partners. The Airwallex account allows merchants to transfer money into their global account and access our FX and payment capabilities which serves as a powerful node that handles the marketplace’s transactional demands, such as:

  • Wallet transfer from other Airwallex Accounts
  • Wallet transfer to other Airwallex Accounts
  • FX conversion within the Multi-Currency Wallets
  • Collection of funds from Bank Accounts
  • Fast/real-time disbursements to Bank Accounts

Case study - Invoicing / supply chain financing platform

As a global logistics warehouse operator, you offer your merchants a value-add service of supply chain financing to help them bridge the working capital settlement time gap between the purchase and sale of goods.

Airwallex’s Scale solution seeks to address the following pain points:

  • You, our platform client (the lender) has no control over the merchant’s (borrower) funds flow and repayment once inventory (the collateral) leaves the warehouse
  • Inefficient and manual onboarding of merchants (borrowers)
  • Complicated settlement relationship between multiple parties involving principals and interests of the loan

Our Scale solution equips you with the tools to strengthen your supply chain financing by providing:

  • Certainty and control over funds flow: Consolidate information and funds flow into one single ecosystem, allowing you to exercise a level of control and visibility over your borrower’s wallet. This will give you the flexibility to manage your supply chain financing process as the lender, with access to your borrower’s sales proceeds from the global marketplace and hence reducing the risk of default by the borrower. Such assurance also allows you to reduce costs of borrowing and offer more competitive pricing to your borrowers.
  • Integrated platform for platform and borrower: Efficient onboarding process and account creation for merchants via our Accounts API, integrating yours and borrowers accounts into one platform.
  • Global account: You can create global accounts for each borrower enabling them to collect proceeds locally and globally and optimise the efficiency of incoming fund flows.
  • Wallet debit and credit functionalities: Full access to control financing, repayments and fee charges as the lender
  • Friendlier user experience: Embed Scale features in your existing user interface through our API and minimise the user experience impact for your users (i.e. borrowers).
