Principles for Finance with Offer & Order

Orders are owned by airlines.

Orders are always to be accurate and up to date.

Orders are the single source of truth for accounting, settlement and reporting (and more).

Strong data validation should be present in the Offer and Order creation.

Accuracy of Offers and Orders are the responsibility of upstream Offer & Order systems.

Correction processes will not happen outside of Orders.

For each Order, all accounting notifications must be received and posted in their intended chronological sequence.

An automated recovery process needs to exist in the event that any accounting notifications are missed during the lifecycle of an Order.

Pricing data are the key to ensuring that Offers are accurate, and Orders are complete.

Pricing information is to be passed to the Order for use downstream, including Finance.

Pricing is split into component values for accounting, reporting and settlement.

Settlement is based on values and data contained in Orders & Order Structures.

Any changes - voluntary or involuntary - require agreement and acceptance between parties to the Order i.e. re-shopping.
