There is a chance that this feature is already available and that I do not know how to use it.
Things that should be added:
Ability to see the agreed upon price and deadlines of pending orders.
List of features that have been upgraded. Example: Did the retail add any salesmen, or did the manufacturing plant upgrade any of the efficiency options.
The seller of the business should be able to write a small message added to their sell, similar to what people are able to write on shipment offers and loan applications.
Edit: 4. Potential buyers should also be able to see if an accepted order has been shipped and not paid for, or if any have been paid for and not shipped.
If any of these are already added, please tell me how to view those options.
Thank you for the hard work you have put into creating this game.
