An Easy Checkout Process for an Online Shopping Platform. Checkout, Done in One Click.
/ The engagement
A One-Click and Split Payment Platform.
The client is a prominent Australian enterprise that wanted a faster, customer-friendly checkout for shoppers on merchant sites. Brainvire built a quick, secure web platform with an SDK and API across two interfaces, delivering one-click and split payment for registered users. The solution runs on iOS, Android, and web, and uses Stripe for ASP.NET so buyers stay on the merchant store at checkout.
/ About the client
The client is a prominent enterprise located in Australia with a sturdy customer base built over its time in the industry. It wanted to reach its customers in a better way and approached Brainvire for an impactful solution that could improve its services and deliver a more customer-friendly experience.
Brainvire's seasoned professionals developed a quick and secure web platform. The team built an SDK and API with two interfaces so customers enjoy one-click payment, and the platform is compatible with iOS, Android, and web. The application supports one-click and split payment for registered users, processing online payments for purchases from merchant sites subscribed to the Instant Pay platform.
/ The approach
Design, architecture, and features, shipped as one program.
Two, one SDK
Merchants and customers had different needs, so the team built an SDK and API with two interfaces that keep the same payment engine consistent across both.
One click
Repeated data entry slowed buyers, so integrated payment forms embedded in the merchant platform give customers checkout in a single click.
Split when needed
Some purchases suit installments, so the platform adds a split payment option alongside one-click for registered users.
Stripe for ASP.NET
Redirects hurt conversion, so Stripe for ASP.NET lets vendors accept payments directly while customers stay on the store during checkout.
/ What stood in the way
Four problems, solved without a maintenance window.
Select a challenge to see how it shaped the build.
Repeated payment data entry
Customers had to fill in payment and address details on every order. The team built an SDK and API for single-click payment, so a returning customer no longer re-enters details for the next purchase.
Redirected checkout flows
Sending buyers to an externally hosted checkout page cost conversions. Stripe for ASP.NET lets vendors accept payments directly on web and mobile web, so customers stay on the vendor store during checkout, which is proven to lift conversion.
Cross-platform compatibility
The service had to work everywhere customers shopped. The team made the platform compatible with iOS, Android, and web, so one-click and split payment behave the same across devices.
Modular, testable code
The client needed a maintainable build. The team used a modular structure with clear method names, which allowed good testability and modular expandability of the application.
