You should document everything you can, so ask your company if they could book the tickets a bit earlier and then E-mail or fax copies to you.
If they insist on doing it last-minute, then ask them to at least E-Mail/fax copies of whatever documentation currently available pertaining to the purpose of your trip to France and the Netherlands. Also ask them to write a letter of invitation stating your purpose and duration of stay in the Schengen Area, and that the tickets have yet to be booked, hence the absence of them amongst the documentation sent with the application.
