would that be more colloquial or ?

or what?
Nein, es ist nicht colloquial, wenn ich "business is taking off" google, krieg ich 20,000 hits.
Der Satz stimmt aber so nicht,
the business was taking off, so they had to order more...
or ................................. ordered more

That's what I say, without actually knowing if it is correct.
None of my German colleagues correct me
