You're given such a high quantity of factories, I don't see why it's needed. Often I have items sitting in factories for hours or even a day before collecting them/having the room to collect them. It's very rare that I don't have what is needed from factories. The only thing that I'm constantly running out of is Flour Bag and I have 3 factories dedicated to producing flour bags alone. They're collected every 3 hours and immediately put back into production.
With the proper variation of production in commercial buildings, you should never run out of anything.
