As part of the collaboration, Bigcommerce merchants will also get access to PayPal's One Touch for web and mobile, enabling shoppers to pay across more than 90,000 online stores in a single touch, without needing to enter user IDs or passwords after their first login.
The newly-released payment option will be made available to all Bigcommerce merchants in the US in the coming weeks, with the international rollout expected later this year.
The joint integration gives Bigcommerce merchants one of the most seamless ways to access the broad capabilities of PayPal and Braintree.
The integration connects Bigcommerce's ecommerce platform with a comprehensive suite of payment services and tools from PayPal, including support for digital wallet payments both online and on mobile, consolidated business management tools and automated fraud protections.
Additionally, merchants using One Touch for web and mobile will benefit from expedited transfers on sales through their online stores, a potential increase in conversions and average order values, as well as early access to all new payment methods supported by PayPal, across all devices, through a single integration.
PayPal senior vice president of global merchant and nextgen commerce, Bill Ready, said PayPal was taking a partner-based approach to payments to help merchants and consumers connect more easily.
