Step 2: Open Atom POS Configuration

  1. Tap the Atom Commerce Ready tile
  2. This opens the Atom POS Configuration screen

​
Step 3: Check POS Mode

  1. In the Atom Commerce Connector section, find POS Mode
  2. Make sure it shows PRO (not LITE)
  3. If it shows LITE, you need to switch to PRO mode:
    • Scroll down to the Mode & Discount Management section
    • Click the Switch to PRO button
    • Wait a few seconds for it to update
If your account was upgraded to PRO but your POS device still shows LITE mode, you may need to clear the session to refresh the connection.

Step 4: Clear Atom Session (If Needed)

If you just switched to PRO mode or something isn’t working:
  1. Scroll to the bottom of the Atom POS Configuration screen
  2. Click Clear Atom Session
  3. This refreshes the connection between your POS device and Atom Commerce
