This field is often used to cross-reference the invoice with the customer's purchasing system. Maximum length: 25 characters. - `termsId` string — The invoice's payment terms, defining when payment is due and any applicable discounts. - `dueDate` string, date — The date by which this invoice must be paid, in ISO 8601 format (YYYY-MM-DD). - `salesRepresentativeId` string — The invoice's sales representative. Sales representatives can be employees, vendors, or other names in QuickBooks. - `shipmentOrigin` string — The origin location from where the product associated with this invoice is shipped. This is the point at which ownership and liability for goods transfer from seller to buyer. Internally, QuickBooks uses the term "FOB" for this field, which stands for "freight on board". This field is informational and has no accounting implications.

Unlike `salesTaxCode`, which only indicates general taxability, this field drives the actual tax calculation and reporting. For invoices, while using this field to specify a single tax item/group that applies uniformly is recommended, complex tax scenarios may require alternative approaches. In such cases, you can set this field to a 0% tax item (conventionally named "Tax Calculated On Invoice") and handle tax calculations through line items instead. When using line items for taxes, note that only individual tax items (not tax groups) can be used, subtotals can help apply a tax to multiple items but only the first tax line after a subtotal is calculated automatically (subsequent tax lines require manual amounts), and the rate column will always display the actual tax amount rather than the rate percentage. - `memo` string — A memo or note for this invoice that appears in reports, but not on the invoice. Use `customerMessage` to add a note to this invoice. - `customerMessageId` string — The message to display to the customer on the invoice. - `isQueuedForPrint` boolean — Indicates whether this invoice is included in the queue of documents for QuickBooks to print. - `isQueuedForEmail` boolean — Indicates whether this invoice is included in the queue of documents for QuickBooks to email to the customer. - `salesTaxCodeId` string — The sales-tax code for this invoice, determining whether it is taxable or non-taxable. This can be overridden at the transaction-line level. Default codes include "Non" (non-taxable) and "Tax" (taxable), but custom codes can also be created in QuickBooks Desktop. If QuickBooks Desktop is not set up to charge sales tax (via the "Do You Charge Sales Tax?" preference), it assigns the default non-taxable sales-tax code configured in the company file to all sales. - `otherCustomField` string — A built-in custom field for additional information specific to this invoice. Unlike the user-defined fields in the `customFields` array, this is a standard QuickBooks field that exists for all invoices for convenience. Developers often use this field for tracking information that doesn't fit into other standard QuickBooks fields. Unlike `otherCustomField1` and `otherCustomField2`, which are line item fields, this exists at the transaction level. Hidden by default in the QuickBooks UI. - `exchangeRate` number — The market exchange rate between this invoice's currency and the home currency in QuickBooks at the time of this transaction. Represented as a decimal value (e.g., 1.2345 for 1 EUR = 1.2345 USD if USD is the home currency). - `applyCredits` object[] — Credits to apply to this invoice, reducing its balance. This creates a link between this invoice and the specified credit transactions. For credit-only applications with no received payment amount, update the invoice using this field. **IMPORTANT**: By default, QuickBooks will not return any information about the linked transactions in this endpoint's response even when this request is successful. To see the transactions linked via this field, refetch the invoice and check the `linkedTransactions` response field. If fetching a list of invoices, you must also specify the parameter `includeLinkedTransactions=true` to see the `linkedTransactions` response field. - `creditTransactionId` string, required — The unique identifier of the credit transaction to apply to this transaction, such as a credit memo, vendor credit, or journal-entry credit. - `appliedAmount` string, required — The amount of the selected credit transaction to apply to this transaction, represented as a decimal string. Decimal string format: exactly 2 decimal places when cents are included and up to 13 digits before the decimal point (for example, "123.45"). - `overrideCreditApplication` boolean — Indicates whether to override the credit. - `lines` object[] — The invoice's line items, each representing a single product or service sold. **IMPORTANT**: 1. Including this array in your update request will **REPLACE** all existing line items for the invoice with this array. To keep any existing line items, you must include them in this array even if they have not changed. **Any line items not included will be removed.** 2. To add a new line item, include it here with the `id` field set to `-1`. 3. If you do not wish to modify any line items, omit this field entirely to keep them unchanged. - `id` string, required — The QuickBooks-assigned unique identifier of an existing invoice line you wish to retain or update. **IMPORTANT**: Set this field to `-1` for new invoice lines you wish to add. - `itemId` string — The item associated with this invoice line. This can refer to any good or service that the business buys or sells, including item types such as a service item, inventory item, or special calculation item like a discount item or sales-tax item. - `description` string — A description of this invoice line. - `quantity` number — The quantity of the item associated with this invoice line. This field cannot be cleared. **NOTE**: Do not use this field if the associated item is a discount item. - `unitOfMeasure` string — The unit-of-measure used for the `quantity` in this invoice line. Must be a valid unit within the item's available units of measure. - `overrideUnitOfMeasureSetId` string — Specifies an alternative unit-of-measure set when updating this invoice line's `unitOfMeasure` field (e.g., "pound" or "kilogram"). This allows you to select units from a different set than the item's default unit-of-measure set, which remains unchanged on the item itself. The override applies only to this specific line. For example, you can sell an item typically measured in volume units using weight units in a specific transaction by specifying a different unit-of-measure set with this field. - `rate` string — The price per unit for this invoice line. If both `rate` and `amount` are specified, `rate` will be ignored. If both `quantity` and `amount` are specified but not `rate`, QuickBooks will use them to calculate `rate`. Represented as a decimal string. This field cannot be cleared. Decimal string format: up to 5 decimal places and up to 10 digits before the decimal point (for example, "123.45"). - `ratePercent` string — The price of this invoice line expressed as a percentage. Typically used for discount or markup items. - `priceLevelId` string — The price level applied to this invoice line. This overrides any price level set on the corresponding customer. The resulting invoice line will not show this price level, only the final `rate` calculated from it. - `classId` string — The invoice line's class. Classes can be used to categorize objects into meaningful segments, such as department, location, or type of work. In QuickBooks, class tracking is off by default. If a class is specified for the entire parent transaction, it is automatically applied to all invoice lines unless overridden here, at the transaction line level. - `amount` string — The monetary amount of this invoice line, represented as a decimal string. If both `quantity` and `rate` are specified but not `amount`, QuickBooks will use them to calculate `amount`. If `amount`, `rate`, and `quantity` are all unspecified, then QuickBooks will calculate `amount` based on a `quantity` of `1` and the suggested `rate`. This field cannot be cleared. Decimal string format: exactly 2 decimal places when cents are included and up to 13 digits before the decimal point (for example, "123.45"). - `priceRuleConflictStrategy` 'base_price' | 'zero' — Specifies how to resolve price rule conflicts when adding or modifying this invoice line. - `inventorySiteId` string — The site location where inventory for the item associated with this invoice line is stored. - `inventorySiteLocationId` string — The specific location (e.g., bin or shelf) within the inventory site where the item associated with this invoice line is stored. - `serialNumber` string — The serial number of the item associated with this invoice line. This is used for tracking individual units of serialized inventory items. - `lotNumber` string — The lot number of the item associated with this invoice line. Used for tracking groups of inventory items that are purchased or manufactured together. - `serviceDate` string, date — The date on which the service for this invoice line was or will be performed, in ISO 8601 format (YYYY-MM-DD). This is particularly relevant for service items. - `salesTaxCodeId` string — The sales-tax code for this invoice line, determining whether it is taxable or non-taxable. If set, this overrides any sales-tax codes defined on the parent transaction or the associated item. Default codes include "Non" (non-taxable) and "Tax" (taxable), but custom codes can also be created in QuickBooks Desktop. If QuickBooks Desktop is not set up to charge sales tax (via the "Do You Charge Sales Tax?" preference), it assigns the default non-taxable sales-tax code configured in the company file to all sales. - `overrideItemAccountId` string — The account to use for this invoice line, overriding the default account associated with the item. - `otherCustomField1` string — A built-in custom field for additional information specific to this invoice line. Unlike the user-defined fields in the `customFields` array, this is a standard QuickBooks field that exists for all invoice lines for convenience. Developers often use this field for tracking information that doesn't fit into other standard QuickBooks fields. Hidden by default in the QuickBooks UI. - `otherCustomField2` string — A second built-in custom field for additional information specific to this invoice line. Unlike the user-defined fields in the `customFields` array, this is a standard QuickBooks field that exists for all invoice lines for convenience. Like `otherCustomField1`, developers often use this field for tracking information that doesn't fit into other standard QuickBooks fields. Hidden by default in the QuickBooks UI. - `lineGroups` object[] — The invoice's line item groups, each representing a predefined set of related items. **IMPORTANT**: 1. Including this array in your update request will **REPLACE** all existing line item groups for the invoice with this array. To keep any existing line item groups, you must include them in this array even if they have not changed. **Any line item groups not included will be removed.** 2. To add a new line item group, include it here with the `id` field set to `-1`. 3. If you do not wish to modify any line item groups, omit this field entirely to keep them unchanged. - `id` string, required — The QuickBooks-assigned unique identifier of an existing invoice line group you wish to retain or update. **IMPORTANT**: Set this field to `-1` for new invoice line groups you wish to add. - `itemGroupId` string — The invoice line group's item group, representing a predefined set of items bundled because they are commonly purchased together or grouped for faster entry. - `quantity` number — The quantity of the item group associated with this invoice line group. This field cannot be cleared. **NOTE**: Do not use this field if the associated item group is a discount item group. - `unitOfMeasure` string — The unit-of-measure used for the `quantity` in this invoice line group. Must be a valid unit within the item's available units of measure. - `overrideUnitOfMeasureSetId` string — Specifies an alternative unit-of-measure set when updating this invoice line group's `unitOfMeasure` field (e.g., "pound" or "kilogram"). This allows you to select units from a different set than the item's default unit-of-measure set, which remains unchanged on the item itself. The override applies only to this specific line. For example, you can sell an item typically measured in volume units using weight units in a specific transaction by specifying a different unit-of-measure set with this field. - `lines` object[] — The invoice line group's line items, each representing a single product or service sold. **IMPORTANT**: 1.

Unlike `otherCustomField1` and `otherCustomField2`, which are line item fields, this exists at the transaction level. Hidden by default in the QuickBooks UI. - `externalId` string, nullable, required — A globally unique identifier (GUID) you, the developer, can provide for tracking this object in your external system. This field is immutable and can only be set during object creation. - `linkedTransactions` QbdLinkedTransaction[], required — The invoice's linked transactions, such as payments applied, credits used, or associated purchase orders. **IMPORTANT**: You must specify the parameter `includeLinkedTransactions` when fetching a list of invoices to receive this field because it is not returned by default. - `id` string, required — The unique identifier assigned by QuickBooks to this linked transaction.
