Switching
Moving mid-year is a nine-day job
We request the books from your current accountant, reconcile every opening balance and file the next return ourselves. You sign one letter.
- Takeover fee: half of one month’s retainer
- Opening balances checked against bank and SGK records
- No gap in e-ledger uploads
Clients
We switched in March, mid-quarter. Defne rebuilt three months of books in nine days and our provisional tax went in on time.
FAQ
Before you switch
Is the estimate the price I will pay?
It is the fee we start from. After a 20-minute call and a look at last month’s bank statement we confirm it in writing; nine in ten clients sign at the estimated figure.
Can you take over from my current accountant mid-year?
Yes. We request the books and e-ledger access, reconcile the opening balances and file the next return ourselves. Takeover is a one-off half-month fee.
Do you work with companies outside İstanbul?
About a third of our clients are in Ankara, İzmir and Bursa. Documents come in through the client portal; we meet on video.
Who signs my returns?
A licensed SMMM partner signs every return. Your senior accountant prepares it and is your daily contact.
What happens if a deadline is missed because of you?
We pay the penalty and the late interest. It is written into every engagement letter; since 2014 it has cost us nothing.
Twenty minutes, your last bank statement, a fixed fee.
