Field Label	Utilisation Guideline
Description	The `Description` field is used to enter a short description of what was acquired.
Related to	The `Related to` field (by default set to Project) is used to relate the invoice to a specific service item: Workflow: the related field is set to the workflow for which the costs specified in the `Amount` field were incurred. Configuration Items: the related field is set to the CI for which the costs specified in the `Amount` field were incurred.

Service Level Agreement: the related field is set to the SLA for which the costs specified in the `Amount` field were incurred.
Service	The `Service` field is automatically set to the service that is linked to the workflow, project, service level agreement or configuration item. If the invoice is linked to multiple CIs, this field is set to the service of the first CI that is linked. If the invoice is linked to an FLSA, this field is empty.

Unit price	The `Unit price` field is used to enter the amount that the supplier has charged per unit that was acquired.

Amount	The `Amount` field displays the product of the `Unit price` field value and the `Quantity` field value. If the amount is entered in a currency that is different from the currency of the account, this amount is also presented in the currency of the account using the foreign exchange rate of the date specified in the `Invoice date` field.
Depreciation method	The `Depreciation Method` field is used to select how the invoice amount is to be depreciated over time. This field is only available when the `Relate to` field is set to Configuration Items. The available options are: Not Depreciated – The value of the CI is not reduced over time. Double Declining Balance – The CI value is depreciated at twice the rate it is done in the straight-line method. Reducing Balance (or Diminishing Value) – The amount of depreciation over a period is less than the amount provided for in the previous period. Straight Line (or Prime Cost) – The same amount is expensed in each period over the CI’s useful life. Sum of the Years’ digits – An accelerated method for calculating a CI’s depreciation.
Depreciation start	The `Depreciation start` field is used to specify the date on which the depreciation period starts.
Useful life	The `Useful life` field shows the number of years within which the configuration item related to this invoice is depreciated. It is taken from the Useful life field of the related product.
Rate	The `Rate` field is used to specify the percentage with which the `Reducing Balance` depreciation method reduces the value of the CI in a year.
Salvage value	The `Salvage value` field is used to register the estimated book value of the configuration item after depreciation is complete, based on what may be received in exchange for the CI at the end of its useful life.
Amortise	The `Amortise` box is checked when the invoice amount is to be amortised over time. This box is available when the `Relate to` field is not set to Configuration Items.
