SunCBS Core Banking System

Sunline is a Shenzhen-listed banking software company with 23 years of fintech experience and more than 800 financial institution clients. In 2016 it began delivering solutions internationally, and it now sells core modernisation to banks outside China, including in Southeast Asia and Central Asia.

SunCBS is Sunline's cloud-native core banking system built on a distributed, microservices architecture with an open API platform. Around it, Sunline offers loan, smart deposit and cash management systems, a digital core, unified payment, an open platform, treasury and FX modules, plus data warehouse, risk data mart and decision engine products. The company also provides consulting, testing and production traffic replay tools for core upgrades.

A Vietnamese joint-stock bank could replace its legacy core with a distributed system for higher transaction volumes. A bank could add a separate digital core for a new digital bank brand. A bank could build a risk data mart and decision engine on top of its core.

Banks can replace legacy cores with a distributed, cloud-native system and migrate in a single big-bang cutover, as City Savings Bank did in 2026. Sunline cites a core banking project completed in a record 13 months. A broad product portfolio lets a bank source core, lending, payments and data platforms from one vendor.

Southeast Asian banks are replacing ageing cores with distributed, cloud-native systems to handle real-time payments and digital products. Regional system integrators such as FPT are partnering with core vendors to speed up these projects in Thailand and other markets.

Headquartered in Nanshan District, Shenzhen, China and listed under stock code 300348. Reports 800+ financial institution clients and began international delivery in 2016. Signed an MoU with FPT in May 2025 to accelerate SunCBS upgrades in Thailand and other markets. International news in 2026 includes City Savings Bank and Halyk Bank of Kazakhstan.
