What we take on

How switching to ORSINI works

  1. Get to know each other

    We discuss what is not working today and what you need. Afterwards you receive a clear quote.

  2. Notice

    You terminate your current mandate, observing the agreed notice period. We tell you what to look out for.

  3. Handover

    We take over the accounting data, latest annual accounts, VAT and payroll records and set everything up with us.

  4. Business as usual – only better

    From the agreed date we handle accounting, payroll and taxes. We keep track of deadlines for you.

These documents help with the switch

  • Latest annual accounts and corporate tax return
  • Accounting data for the current year (software export or bank statements)
  • VAT returns and correspondence with the Federal Tax Administration
  • Payroll records: employee list, insurances, latest payslips
  • Powers of attorney and access rights your previous accountant had
FAQ

Change accountant: good to know

When is the best time to switch?

Easiest at the start of a financial year or quarter, because there is a clean cut. Switching mid-year is also possible – we then take over from an agreed date.

Does my previous accountant have to hand over my records?

Your accounts and receipts belong to you. When the mandate ends you get your records back. We tell you exactly which data we need.

Who prepares the last annual accounts?

We agree this with you. Often the previous accountant closes the last full year and we start with the new one. But we can also take over an open closing.

Will you change my accounting software?

Only if it benefits you. We work with the solution that suits you and set up interfaces where needed so you can send receipts easily.
