Verifying or Changing WinOMS Settings
Payment Manager supports multiple Merchant IDs for multi-location practices, so that each location uses its own Merchant ID.
Important: To assign Merchant IDs, you need the assistance of a representative from GPI. Assigning the wrong ID will impact payment processing.
To assign Merchant IDs to office locations:
Select Billing > Payment Manager > Assign Merchant. The Choose Merchant Id window is displayed with the Office number and Merchant name on the left and the Merchant ID on the right.
Note: The office number corresponds to the office to which you are logged in.
In the Merchant ID fields, select the ID that corresponds to each office and provider.
Click Ok. The Office/Provider/Merchant ID combination is saved in both WinOMS and Payment Manager.
Log out and then log in to another location. Repeat step 1. The Choose Merchant Id window is displayed for the second office location.
Repeat steps 2 and 3.
Repeat this process for each office location you want to set up.
