Toss Bank said on Tuesday it is strengthening its banking lineup for sole proprietors by simultaneously launching a business account with sales and expense management functions and a debit card that offers vault and cashback benefits.

The products for sole proprietors are designed to allow small merchants and self-employed users who find it difficult to use separate bookkeeping services to manage sales and expense flows with a single account. The bank said it focuses on helping business owners concentrate more on running their operations.

The account for sole proprietors automatically classifies sales and expenses based on deposit and withdrawal records, allowing users to see business cash flows at a glance.

It also set up an integrated management environment for sole proprietors operating multiple business locations. It lets users view and manage transaction histories and status separately by location, improving ease of management.

The sole proprietor vault launched with the account is a parking account service that allows users to separate and hold funds in up to 30 categories depending on purpose, such as payroll, rent and value-added tax. It allows deposits and withdrawals at any time and offers an annual interest rate of 1.4 percent before tax. Interest is paid even if funds are deposited for a single day.

Toss Bank also introduced a debit card for sole proprietors linked to the business account. Through a business cashback Season 1 promotion running until Nov. 30, 2026, it provides immediate cashback of 0.3 percent of the payment amount to the business account for purchases at all merchants in South Korea.

A Toss Bank official said the goal of the sole proprietor account is to enable users to manage sales and expenses and see cash flows at a glance with a single account. The official added that Toss Bank's idea of productive finance is creating an environment in which business owners can focus solely on their core work through essential innovation of the account itself.
