Always have your customers pay in advance

Hi Brooke,

I heard that here in France the companies are used to pay 30 to 90 days after you deliver a training. Having them pay in advance will seem strange and going against the flow to them.
How could I get them to sign up and change their habits in a drastic way ? … and still willing to sign up !
Or the counsel is only for private clients ?

Thanks for the answer !
