In your request, either price or percentage (ratePercent) is required for each InvoiceLineItem. If you set one, do not set the other.
If ratePercent is set for a line item, the line item amount is (ratePercent) x (sum of other line item amount values). If price is set, amount is (quantity) x (price).
What is an invoice?
An invoice represents an amount that you are owed by a customer for goods and services that you provide.
You can create an invoice with /Crud/Create/Invoice.json. In the invoice, add invoice line items to record details about individual goods or services. In addition, you can associate line items to accounts tracking objects, such as item (/Item.json) or chart of accounts (/ChartOfAccounts.json).
Other invoice features:
You can reduce the total invoice amount with an invoice credit (/CreditMemo.json). Total invoice amount, credit memos, and any remaining invoice amount to be paid or recorded is available with /Crud/Read/ReceivedPay.json.
exchangeRate is a required additional field for creating an invoice for an international customer. In addition, each invoice line item amount is in the foreign currency. Retrieve the current exchange rate with /GetDynamicExchangeRateQuote2.json.
