Using Manager io (Cloud) from multiple Android Tablets

1

we have more than 100 sales force in the field, they are sending order to HQ by other android apps, and the HQ has to transfer the order manually to Manager IO, by key in.
I am thinking of letting the field sales man sending order (key in Manager io cloud version) from their tablets, with different user IDs.

  1. Will it be problem or jam when so-many sales people try to access manager io same time for key in orders.
  2. Maximum users number allowed in manager io.
  3. Please advise how to ease the traffic or prevent slowdown, if there will be problem.
    Thank you .

No. The actual data volume being transmitted by even 100 users at once is trivial.

No practical limit.
