Invoice ID Behavior Program Wide -Each invoice has a unique ID
Project Specific -Each project starts Invoice numbering at a specific number
Identical IDs Studiometry can help you locate and fix any Projects or Clients that somehow end up with the same ID numbers. One way that you can end up with identical ID's is by creating a Project while not connected to a network, and then having someone else also create a Project while they are connected to the network. An easy way to avoid this is by using the random number or random letter tags in your ID formats.
