Its target clients are business entities requiring compliance with Turkish tax law, the Turkish Commercial Code, the Code of Obligations, Labor Law, and Social Security Institution processes.

The firm operates as a traditional professional services practice with no proprietary technology platform, software product, or AI-enabled tooling.

Service delivery is provided directly from the single Istanbul headquarters, with the firm positioning itself as a long-term business partner grounded in professional ethics, independence, and intergenerational knowledge transfer. Marketing channels are not documented; the firm maintains a basic website and minimal social media presence.

ACA's revenue model is professional services fee-based, with pricing described as quote-based and tailored to client scope. No fee structures, rate cards, or pricing tiers are publicly disclosed.

• PwC Turkey: One of the Big 4 in Turkey, providing audit, tax, legal, and consulting services. While ACA targets smaller SMEs, PwC Turkey competes for the same compliance, payroll, and advisory wallet and represents the upper bound of the local professional services market.

• Grant Thornton Turkey: Grant Thornton's Turkish member firm offers audit, tax, and advisory services to mid-market and SME clients in Turkey. Directly comparable to ACA in target customer segment and service mix, but with significantly more scale and international network reach.
