EasyBilling is a standalone application, and does not have network/multi-user access features.
However, you can set the Data Folder (we called it workspace in EasyBilling) to a network drive/shared folder, so that EasyBilling from different computers can access the same "data".
In EasyBillng, you can set your workspace in menu "File > Switch Workspace"and create a new workspace in a network drive.
For example, Z drive is the network drive. We create a "easyBilling\" folder in Z drive and set the Z:\easybilling folder as workspace folder.
In EasyBilling of second computer, you also need to create a workspace.
You need to set the same workspace folder (as in the first computer), but choose "Connect existing workspace".
EasyBilling in two computers point to the same folder in the network drive now.
There is one limitation with this approach, different EasyBilling cannot access at the same time.
As the database is locked when EasyBilling is running, other EasyBilling can only connect the same workspace in READ-ONLY mode.
