Before uploading your data or if you get an error message saying that you need to allow Third party products access, you can do so from Simply Accounting, using the Admin user account.
Click Setup in the menu, and select Set Up Users & Roles (this option is only accessible from the Admin user account. So if you see it, it means you are Admin).
* If you do not see this option, it means you are not the admin and will not have the ability to change any user settings.
On the Set Up Users & Roles window select the sysadmin account and click Modify User.
Then make sure Third party products have Read & Write access and click OK.
bridgeD will not write on your data file, this is the permission level required by Simply Accounting.
