Delivery window rules reference
Last updated: August 16, 2026
Every field in the Pricing Rule and Tag Rule drawers, defined. For how to create and manage rules, see delivery window pricing and tag rules.
Note
Pricing and tag rules are a beta capability within delivery windows. Reach out to Nash if you'd like early access.
The two drawers share the same top section. Only the per-tier outcome differs: a pricing rule sets a price, a tag rule sets a tag string.
Shared fields (both drawers)
| Field | Options (default) | What it does |
|---|---|---|
| Pricing Rule Name / Tag Rule Name | Text (required) | Identifies the rule in the rules list. |
| Applicable Zones | Zone multi-select (at least one required) | The zones the rule applies to. A zone can belong to only one rule of that type at a time, so zones already used by another rule aren't offered. |
| Calculated Metric | Select — options come from your organization's configuration (defaults to the first metric; required) | The signal the rule watches. The available metrics are set for your org; Nash computes their values. |
| Rule Status | Off / On (On) | Whether the rule is active. On by default, so a new rule takes effect once saved unless you turn it off. Matches the Is Active badge and the Toggle Rule action in the list. |
| Sort direction | Increasing / Decreasing (Increasing) | Whether tiers apply as the metric increases or decreases. This also changes the threshold wording next to each tier's Value (see below). |
Tiers
Both drawers hold an ordered list of Tiers — at least one is required. A tier is a threshold on the calculated metric plus the outcome to apply at that threshold. Use Add Tier to add one and Remove to drop one.
Tier fields — pricing rule
| Field | Options (default) | What it does |
|---|---|---|
| Value | Number 0–100, step 0.01 (0) | The metric threshold for this tier, entered as a percentage. The hint beside it reads "{value}% and above" when Sort direction is increasing, or "{value}% and below" when decreasing. |
| Use Price Offset | Off / On (Off) | Chooses how this tier's price is applied. Off, the tier sets a flat price; on, the tier adds to the window's original price. The price field's label changes to match. |
| Flat Price (when Use Price Offset is off) | Number (0) | The price the window is set to at this tier. |
| Applied price on top of original (when Use Price Offset is on) | Number (0) | The amount added to the window's original price at this tier. |
Tier fields — tag rule
| Field | Options (default) | What it does |
|---|---|---|
| Value | Number 0–100, step 0.01 (0) | The metric threshold for this tier, entered as a percentage, with the same "{value}% and above / below" hint driven by Sort direction. |
| Tag | Text (required) | The tag applied to the window when the metric reaches this tier. A tag rule has no price or offset. |
Note
The Value you type is a percentage from 0 to 100, but Nash stores it as a fraction — it is divided by 100 on save (so 50 is stored as 0.5). You always enter and read it as a percentage in the drawer; the conversion happens behind the scenes.
Important
The field labels, options, and defaults above are what the drawer shows. How a chosen metric is calculated, when it's recomputed, and exactly how a tier's price or tag is applied to a live window are handled by Nash on the server — the drawer controls the inputs, not the runtime behavior.
