Tier Modifier node
Delivery and logistics integration with a tier system — route orders through delivery services according to configurable tiers.
Tier Modifier (picker_express) integrates delivery/logistics services with a tier system: orders flowing through it are routed and priced according to the tier rules you configure.

Configuration
Open the node (double-click) to edit it. Key fields:
- Node ID / Name — the identifier used in variables and the display name on the canvas.
- Tiers — the routing/pricing rules for the delivery service.
Inputs & outputs
It receives order data and emits the routed/updated order. Downstream nodes reference its output with {{node_id.field}} — see the variables reference.
