Frequent questions from Winterthur
Can Planet handle accounting for a Winterthur tech company?
Yes, from the GmbH formation (CHF 2'500) through monthly bookkeeping from CHF 440 and the corporate tax return, we cover the full lifecycle.
Do you perform the audit yourselves?
We prepare and accompany — the statutory audit is performed by an independent audit firm. We're happy to refer a suitable one.
Does my company even need an audit?
That depends on size and legal form (limited/ordinary audit, opting out). We clarify what applies to you in the first meeting.
