Representative engagements
The following are anonymized, illustrative examples of the situations we are brought in to solve. Figures and identifying details are omitted to protect client confidentiality.
Accounting takeover — software subsidiary three months behind on reporting
Challenge: A foreign-owned software subsidiary’s local bookkeeper filed taxes but produced no financials the HQ could read; the parent had no visibility.
What we did: Took over the e-Ledger, rebuilt the chart of accounts against the group format, reconciled the year to date and delivered a monthly English pack from the next close — with filings never interrupted.
Outcome: Head office moved from quarterly guesswork to a fixed monthly close it could actually use.
Non-resident VAT registration for a foreign trading company
Challenge: A non-resident company needed to account for Turkish VAT on its activity without a full local establishment.
What we did: Handled the registration and set up compliant monthly VAT reporting, with clear guidance on what triggered the obligation.
Outcome: The company became and stayed VAT-compliant in Turkey without over-building local structure.
Payroll set-up for a startup’s first Turkish hires
Challenge: A foreign startup had budgeted only the gross salary for its first Turkish engineers and had no SGK set-up.
What we did: Built a fully loaded employer-cost model, registered the employees with SGK correctly, and ran monthly payroll and the combined declarations.
Outcome: No surprises on cost or compliance — and a clean base to scale the team.
Group-format reporting for a European parent
Challenge: A European group received only a Turkish trial balance from its subsidiary and could not see margin or cash.
What we did: Mapped the chart of accounts to the group template once, then delivered a monthly pack in the group’s format and reporting currency.
Outcome: The Turkish entity now drops straight into group consolidation each month.
