Since we’re the ones writing the article, we thought we’d start with ourselves. Here are some of the benefits and features of working with Zai to process payments.

Once you’re onboarded, you’ll always be able to collect payments

One of the issues with some other card payment gateways is that they only do know your customer (KYC) with you and onboarding once your first customer payment is being disbursed.

Although that means that you’ll sign up for their service rapidly and can start accepting payments quickly, it also means that at the most critical moment (at disbursement) you’ll need to go through KYC, which could cause delays and cause customer experience issues.

This can be frustrating and impact business negatively, especially if you are a large business processing thousands of card payments per day.

With Zai, we go through a rigorous onboarding process, where we’ll run through all our compliance checks and KYC before you start accepting payments. The process does take longer, but once you’re onboarded, you won’t have to worry about frozen or suspended funds or delays.

No fee for active users, and transaction fees are affordable

Whereas Adyen charges $0.12 + payment method fee (1) and Stripe charges 1.75% + $0.30 for domestic credit cards and 2.9% + $0.30 for international cards (12), at Zai, we charge 1.5% + $0.16 for domestic credit cards and 2.8% + $0.16 international cards. We also offer bespoke rates for large-volume and high-value transaction businesses.

We don’t charge any fees for active users, which makes us a lot cheaper in the long run, especially if you’re working with thousands of active users.

Offer multiple payment methods so your customers get a great purchase experience

At Zai, we do more than offer card payments. We’ve been managing payments for businesses for over 10 years in Australia. We’re specialists in split payments and building custom payment models and solutions.

With our API, you’ll be able to offer customers more payment methods, including:

As your business evolves, you might also want to set up split payments, or a custom payment solution that works specifically for your business model. We can also help you integrate recurring payments and billing.

(Want to dig a bit deeper into the nuts and bolts of what we offer? Feel free to take a look at our API docs).

For example, we helped a property tech company build a custom payment solution for their complex payment flow (more on this later).

We work with you as a long-term partner

At Zai, we’re not self-serve or hands-off with our clients. We offer a personal and partnership approach with our clients to ensure you always have the best customer support possible.

Since we’re based in Australia, we offer localised support available at all times: we’re only a phone call away from helping you get what you need.

This allows us to guide you through every step of your payments journey with us and offer you consultative support once you’re onboarded.

Access the highest level of security and protect your customers

Our API comes with built-in protection. You’ll automatically be able to implement anti-money laundering (AML) and KYC checks and sanctions screening.

With our API, you can rest assured you’ll have access to:

  • Fraud protection.

  • User verification.

  • Transaction monitoring.

  • Dispute investigation.

And thanks to our recent partnership with Worldpay, we can help you scale by accepting overseas payments with global reach. Our partnership will allow us to accept cards all around the world as well as enable 3D Secure 2.0, real-time fraud detection and digital wallets. We can even offer local payment methods, like Apple Pay and Google Pay.

Our sister company, CurrencyFair, gives business customers access to local bank accounts in leading markets that enable you to treat your international payments as domestic payments to save you both time and expenses. With CurrencyFair’s multi-currency accounts, you can exchange currencies safely and transfer funds in 150+ countries.

How property management companies can use Zai’s API for multi-party payments

Proptechs are complex entities with multiple stakeholders, suppliers and liabilities, such as:

  • Investors.

  • Landlords.

  • Standard utility providers.

  • Service providers like tradespeople.

  • Insurance.

  • Financial liabilities (e.g., loan repayments).

Every stakeholder will have different amounts due and they often have specific payment requirements, such as requesting payments to arrive on certain due dates.

Splitting payments and transferring them to multiple parties manually for all of your properties means you’ll spend hours calculating and completing these payments – a process that isn’t sustainable as you grow your business and add more properties.

Instead, you can automate this process thanks to Zai’s API:

  1. Create a custom payment flow as soon as you set up Zai’s API.

  2. You can then provide a user ID to each party on every side of a payment.

  3. Each user ID will then receive a unique wallet that links directly to the customer.

  4. You can then decide how you want to split and execute every payment event (also known as an item in the chart below) by creating rules through an API request.

  5. According to your rules and the system’s logic, payments can move fluidly between wallets to the respective parties.

This makes it a lot easier to move money from the wallet to each party’s financial account and take your own fee simultaneously.

Of course, Zai's split payments API doesn’t only work with the property management industry. We work with online marketplaces and platforms. Even B2B suppliers who work with consumer goods use our split-payment API to successfully manage fast-paced transactions across multiple parties.

Who is Zai best for? We’re best for companies with complex payments needs and that want to offer multiple payment methods to customers. Get in touch with us now if you’d like to get set up.
