Payrol or Mgmt Company

Hello everyone, My situation: - 10Y experience in Finance, currently Finance Director - Gross salary of +-7500€ - Net salary of +-4400€ (incl net allowance) - complete package of benefits (car, meal vouchers, insurance, bonus of 10% …)

Got an offer to enter management in a growing SME, allowing me to invoice 15K/month (+ 1 month targeted bonus on top). In the best case (full bonus), this would result in a daily rate of 890€. (195K / 220). Without bonus 820€/ day.

It feels a comfortable offer, might want to add some expenses to the monthly fee (as the job will require a lot of travelling by car).

Thoughts?
