IT for Accounting Firms (Mali Müşavir)
Turkish accounting firms (mali müşavir, SMMM) handle dozens or hundreds of client books — each with distinct KVKK obligations, e-defter / e-fatura mandates, and a need for strict data segmentation. We design IT around multi-client confidentiality and operational efficiency.
Atop Luca/Mikro
Accounting software preserved; we layer M365 + security.
Multi-Client Segmentation
SharePoint structure with information barriers between clients.
KVKK Posture
Each client file under appropriate KVKK lawful basis and retention.
e-Defter Retention
Long-term immutable storage aligned to GİB requirements.
What's different about accounting firms
- Multi-client confidentiality — each client's data must be isolated from other clients.
- E-defter / e-fatura / e-arşiv mandates — operational reality, GİB integrator required.
- Long retention — accounting records often 10+ years.
- Seasonal load — quarterly / annual filing periods spike workload.
- Many staff handling many clients — access control granularity matters.
- KVKK — client and end-customer personal data, both layers in scope.

Frequently Asked Questions
SharePoint architecture: one site collection per client (or per client tier), with Entra security groups controlling membership. Information barriers prevent cross-client information sharing. Sensitivity Labels mark each client's data as "Confidential — Client X".
GİB requires e-defter retention for the legal period. We deploy Acronis with immutable storage covering the full window, indexed for quick retrieval during audit.
Entra groups define role-based access. Junior staff see only their assigned clients. Senior staff see broader sets. Partner-level sees all. Audit log records every access for compliance.
Handled the same way as any other professional services firm — your internal accounting (often the same Luca/Mikro install or a separate tenant) sits alongside client work, with role-based access.
