Delivery window pricing and tag rules

Last updated: August 16, 2026

Pricing and tag rules adjust a delivery window dynamically based on a calculated metric — a signal Nash computes for the window, such as how full it is. A pricing rule changes the window's price as that metric crosses thresholds you define; a tag rule attaches a tag instead of changing the price. Both are built the same way, on the Pricing Rules and Tag Rules tabs.

Note

Pricing and tag rules are a beta capability within delivery windows. Reach out to Nash if you'd like early access.

This page covers creating and managing rules. For the meaning of every field in the drawers, see the companion delivery window rules reference.

How a rule works

A rule watches one calculated metric for the zones you attach it to. You define tiers — threshold points on that metric, expressed as a percentage. As the metric reaches a tier, the rule applies that tier's outcome: for a pricing rule, a new price or a price adjustment; for a tag rule, a tag string. The Sort direction decides whether tiers apply as the metric increases or decreases.

The exact metric values and when the engine recomputes them are handled by Nash on the server. What you control on this page is which zones a rule covers, which metric it watches, and the tiers and their outcomes.

Read the rules list

Each of the Pricing Rules and Tag Rules tabs is a table with:

  • Name — the rule's name.
  • Is Active — an Active or Inactive badge.
  • Actions — a per-row menu with Edit, Toggle Rule (flip active on or off), and Delete.

Select a row to open its drawer. An empty tab shows "No pricing rules created yet." or "No tag rules created yet."

Create a pricing rule

  1. On the Pricing Rules tab, select New Pricing Rule to open the Create Pricing Rule drawer.
  2. Enter a Pricing Rule Name.
  3. Choose Applicable Zones. At least one is required. Zones already used by another pricing rule aren't available — a zone can belong to one pricing rule at a time.
  4. Pick a Calculated Metric. The list of metrics comes from your organization's configuration.
  5. Leave Rule Status on to make the rule active, or turn it off to save it inactive.
  6. Set the Sort direction for whether tiers apply as the metric increases or decreases.
  7. Define at least one tier. For each tier, set the Value (the percentage threshold, 0–100), then either an Applied price on top of original or a Flat Price, using the Use Price Offset switch to choose between them. Use Add Tier for more thresholds and Remove to drop one.
  8. Select Create Rule.

Create a tag rule

A tag rule is built exactly like a pricing rule — same Name, Applicable Zones, Calculated Metric, Rule Status, Sort direction, and tier thresholds — except each tier carries a Tag string instead of a price, and there is no price-offset choice.

  1. On the Tag Rules tab, select New Tag Rule.
  2. Fill in the name, zones, metric, status, and sort direction as above.
  3. For each tier, set the Value threshold and the Tag to apply.
  4. Select Create Rule.

Edit, toggle, and delete

  • Edit — open a rule from its row or the Edit action, change any field, and select Update Rule.
  • Toggle Rule — flip a rule between Active and Inactive without opening it. You can also toggle Rule Status inside the drawer.
  • Delete — remove a rule from its row's actions menu. Deleting a rule cannot be undone.
