Walmart-backed fintech One is planning to launch a buy now, pay later product, according to CNBC.
The move would see online and in-store Walmart customers offered the option to pay for their shopping in instalments.
The service could be rolled out next year, says CNBC, citing sources.
Walmart has recently been ramping up its presence in financial services through One, the independent fintech unit established under the leadership of former Goldman Sachs consumer banking chief Omer Ismail.
In September, Bloomberg reported that the world's largest retailer was gearing up to beta test a digital checking account with employees and customers, with lending and investing products expected to follow.
