​
PRO mode vs LITE mode

Atom Commerce POS has two discount modes. Which one you use depends on your Shopify POS subscription.
ModeRequiresHow discounts apply
PROShopify POS ProApplies discounts natively through Shopify’s discount system
LITEAny Shopify POS planApplies discounts as line-item price adjustments
Which mode should I use? Use PRO if your store has Shopify POS Pro. PRO mode applies discounts through Shopify’s native discount infrastructure, which means they appear correctly on receipts and in reports. Use LITE if you’re on a standard Shopify POS plan. LITE mode still applies discounts, but it does so by adjusting line-item prices directly. The discount is visible to the shopper and reflected in the cart total, but it shows differently in Shopify’s reporting.
If you’re not sure which plan you’re on, check Shopify Admin → Settings → Plan or ask your Shopify account contact. Switching modes doesn’t change your pricing — it only affects how Atom Commerce applies discounts.

​
Switching modes

The current mode is shown in the POS Mode row. To switch:
  1. Tap Switch to PRO or Switch to LITE (whichever appears)
  2. The mode saves immediately
  3. Tap Clear Atom Session to refresh the connection before your next sale

​
Apply Order Discounts

Tap Apply Order Discounts to manually trigger Atom Commerce to evaluate the current cart and apply any qualifying order-level discounts. This is useful when:
  • A discount didn’t apply automatically
  • You just switched POS modes and want to refresh
  • A staff member modified the cart in a way that may have skipped discount evaluation

​
Maintenance actions

​
Clear Atom Session

Clears the current session and re-establishes the connection between your POS device and Atom Commerce. Use this if:
  • Upsells aren’t appearing after adding items
  • You switched POS modes
  • You’re seeing stale data from a previous cart

​
Network status

The Network Status row shows whether your POS device can reach Atom Commerce.
StatusWhat it means
Online (green)Connected. Upsells and discounts are live.
Slow Network (orange)Connected but response times are high. Upsells may be delayed.
Offline (grey)No connection. Upsells are unavailable until connectivity is restored.
The latency number (e.g. 142ms) is the last measured round-trip time to the Atom Commerce API. Values below 500ms are normal. Above 1000ms, you may see the tile switch to the slow network state.
