What is it?

Checkout rules control which delivery options are shown to customers and how they are priced. Ingrid uses four types of rules, each applied at a different stage during checkout:

Rule Type	What It Does
Region Rules	Filters delivery options by country and postal code
Filter Rules	Removes options based on cart contents, product attributes, or order value
Post Filter Rules	Refines the list based on which carriers actually responded
Price Rules	Adjusts delivery prices based on conditions (e.g. free shipping above a threshold)

How rules work together

When a customer reaches checkout, rules are applied in this order:

Region rules — "Is this delivery option available in the customer's location?"
Filter rules — "Should we request this carrier, given what's in the cart?"
Carrier check — Ingrid contacts carriers to confirm availability, get delivery times, and find pickup points
Post filter rules — "Now that we know what's available, should we hide any duplicates or show a fallback?"
Price rules — "What should this delivery option cost for this specific order?"
Display — final list of delivery options shown to the customer

Each step narrows the list further. By the time the customer sees delivery options, they are guaranteed to be available, relevant, and correctly priced.

When to use which rule type

I want to...	Use
Limit a delivery method to specific countries or postal codes	Region Rules
Hide a delivery method for heavy or oversized items	Filter Rules

Show a safety-net option when all other carriers are unavailable	Post Filter Rules

Where to configure

All rules are configured in the Ingrid Merchant Platform under:

Delivery Checkout → Regions → [Select Region]

Rule Type	Where in the platform
Region Rules	Region settings — country and postal code fields
Filter Rules	Delivery Categories or Carrier Products → Filter rules field

Delivery option not appearing?

If a delivery option doesn't appear at checkout, check in this order:

Region — is the carrier product configured for the customer's country and postal code?
Filter rules — is a filter rule excluding it based on cart contents (weight, value, dimensions)?
Carrier availability — is the carrier actually returning this option for the given address?
Post filter rules — is a post filter rule hiding it because another method is present?
Price rules — if the option appears but with incorrect pricing, check rule order (first match wins)
