Update a bill

The current QuickBooks-assigned revision number of the bill object you are updating, which you can get by fetching the object first. Provide the most recent revisionNumber to ensure you're working with the latest data; otherwise, the update will return an error.

The vendor who sent this bill for goods or services purchased.

The Accounts-Payable (A/P) account to which this bill is assigned, used for accounts-payable tracking. If omitted, QuickBooks Desktop uses the default A/P account configured in the company file.

IMPORTANT: If this bill is linked to other transactions, this A/P account must match the payablesAccount used in those other transactions.

The date of this bill, in ISO 8601 format (YYYY-MM-DD).

The date by which this bill must be paid, in ISO 8601 format (YYYY-MM-DD).

The case-sensitive user-defined reference number for this bill, which can be used to identify the transaction in QuickBooks. This value is not required to be unique and can be arbitrarily changed by the QuickBooks user.

Maximum length: 20 characters.

The bill's payment terms, defining when payment is due and any applicable discounts.

A memo or note for this bill that appears in the Accounts-Payable register and in reports that include this bill.

The sales-tax code for this bill, determining whether it is taxable or non-taxable. If set, this overrides any sales-tax codes defined on the vendor. This can be overridden on the bill's individual lines.

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.

The market exchange rate between this bill'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).

When true, removes all existing expense lines associated with this bill. To modify or add individual expense lines, use the field expenseLines instead.

When true, removes all existing item lines associated with this bill. To modify or add individual item lines, use the field itemLines instead.

The unique identifier assigned by QuickBooks to this bill. This ID is unique across all transaction types.

The type of object. This value is always "qbd_bill".

The date and time when this bill was created, in ISO 8601 format (YYYY-MM-DDThh:mm:ss±hh:mm), which QuickBooks Desktop interprets in the local timezone of the end-user's computer.

The date and time when this bill was last updated, in ISO 8601 format (YYYY-MM-DDThh:mm:ss±hh:mm), which QuickBooks Desktop interprets in the local timezone of the end-user's computer.

The current QuickBooks-assigned revision number of this bill object, which changes each time the object is modified. When updating this object, you must provide the most recent revisionNumber to ensure you're working with the latest data; otherwise, the update will return an error.

The date of this bill, in ISO 8601 format (YYYY-MM-DD).

The date by which this bill must be paid, in ISO 8601 format (YYYY-MM-DD).

The total monetary amount due for this bill, represented as a decimal string. This equals the sum of the amounts in the bill's expense lines, item lines, and item group lines. The amount due minus any credits or discounts equals the open amount.

The market exchange rate between this bill'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).

The monetary amount due for this bill converted to the home currency of the QuickBooks company file. Represented as a decimal string.

The case-sensitive user-defined reference number for this bill, which can be used to identify the transaction in QuickBooks. This value is not required to be unique and can be arbitrarily changed by the QuickBooks user.

Indicates whether this bill has not been completed or is in a draft version.

A memo or note for this bill that appears in the Accounts-Payable register and in reports that include this bill.

Indicates whether this bill has been paid in full. When true, openAmount will be 0.

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.

The remaining amount still owed on this bill, represented as a decimal string. This equals the bill's amount minus any credits or discounts.

NOTE: Two rare QuickBooks Desktop behaviors can make openAmount unreliable on bills:

• openAmount can be omitted from bill query responses.
• A known QuickBooks Desktop bug can cause openAmount to reflect the vendor's aggregate open accounts-payable balance rather than the documented remaining balance for that individual bill.

If you need the amount currently payable on each open bill, use Conductor's /quickbooks-desktop/bills-to-pay endpoint and read bill.amountDue instead of relying on openAmount from the Conductor bills endpoint. The bills-to-pay endpoint is not a general replacement for the Conductor bills endpoint, because it is scoped to open bills and available credits for a vendor and returns bill-payment data rather than full bill records.

If you cannot use /quickbooks-desktop/bills-to-pay and must derive a fallback from Conductor bills endpoint results, re-query the bills with includeLinkedTransactions=true and compute a best-effort open amount as amountDue plus the sum of signed linkedTransactions[].amount values for all entries where linkedTransactions[].linkType is "amount".
