A company opening or opening party costs roughly €200 to €500+ per person ex. VAT for 250 to 500 guests. For 500 to 1,000 guests you should count on roughly €175 to €450+ per person. For 1,000 to 2,000 guests you should count on roughly €150 to €400+ per person. All amounts excluding VAT, including venue, catering, entertainment and production.
A company opening combines a ceremonial moment with a festive programme. The spread in the budget depends on whether press, local officials or a broad audience are invited.
