I found that in most of the Netherlands, certainly south of Amsterdam, you could get away with English. But it isn't the everyday business language.

This is true. The further away you go from the bigger cities that aren't touristy, the more friction there is if you only speak English. A1 level of Dutch is plenty to navigate and do personal errands, and even then others still might swap to English to communicate with you if they hear an accent.
