Our Story
Built in Matara, trusted across borders.
SDK Associates began in a two-room office in Matara with a simple conviction: that a growing business deserves an accountant who understands the whole picture, not just the ledger.
Fifteen years on, we advise companies across manufacturing, retail, technology, hospitality, and financial services — from family businesses filing their first audited accounts to listed groups managing complex, multi-entity reporting.
What has not changed is the way we work. Every engagement is led by a partner, every deadline is treated as fixed, and every recommendation is one we would act on ourselves.
Founded in 2015 by Samurdika Rajapaksha.
