Hello Jaccob,
For data processing on Trimble Business Center, you do not need a login to use Trimble Access Services. In Trimble Business Center, select Home tab and click Access Services. When the screen loads go to upper right corner and change 'Navigate to' drop-down menu to 'Survey Tools'.

If you would like to sync files between office and field, then you can use Trimble AccessSync* service with your Trimble Connect account. We haven't fully integrated Trimble Connect with Trimble Business Center yet, but you can install AccessSync on your controller and using Trimble connect login mode to synchronize data.
More details available here

- Trimble File Conversion
* Notes
- You can install and run AccessSync if you have a valid Software Maintenance Agreement for Trimble Access.
- The AccessSync service is no longer available on the following controllers: GeoXR, TSC2, TCU, Trimble S3, Trimble M3.
Best Regards,
Fern Udomrasami
