Case studies
A Contact is an individual or business entity to which products and services are sold to or purchased from. The Contact model contains both Customers, in which products and services are sold to, and Vendors (or Suppliers), in which products and services are purchased from. A Contact is a Vendor/Supplier if the is_supplier property is true. A Contact is a customer if the is_customer property is true.
A CreditNote is transaction issued to a customer, indicating a reduction or cancellation of the amount owed by the customer. It is most generally used as an adjustment note used to rectify errors, returns, or overpayments related to a sales transaction. A CreditNote can be applied to Accounts Receivable Invoices to decrease the overall amount of the Invoice.
An Employee is an individual who works for the company of the linked account. The Employee model contains both contractors and full time employees. An Employee is a contractor if is_contractor property is True An Employee is a full time employee if is_contractor property is False
The Expense object is used to represent a direct purchase by a business, typically made with a check, credit card, or cash. Each Expense object is dedicated to a grouping of expenses, with each expense recorded in the lines object. The Expense object is also used to represent refunds to direct purchases. Refunds can be distinguished from purchases by the amount sign of the records. Expense objects with a negative amount are purchases and Expense objects with a positive amount are refunds to those purchases.
A General Ledger Entry is a record of a financial transaction that is posted to the general ledger, the central repository of a company’s financial data. The GeneralLedgerTransaction object is a singular endpoint to pull all transactions posted to a company’s general ledger. The transaction that generated the GeneralLedgerTransaction can be found by referencing the underlying_transaction_type and underlying_transaction_remote_id fields. The lines of a GeneralLedgerTransaction object will always have equal amounts of debits and credits.
The IncomeStatement object is used to represent a company’s income, the cost of sales, operating expenses, and other non-operating expenses. The object also includes other important values like gross profit, gross operating profit, and net income. This represents a period of time (month, quarter, or year).
The Invoice object represents an itemized record of goods and/or services sold to a customer or bought from a vendor. Represents a Bill when the Invoice type is ACCOUNTS_PAYABLE. References an Invoice when the Invoice type is ACCOUNTS_RECEIVABLE.
A JournalEntry is a record of a transaction or event that is entered into a company's accounting system. The JournalEntry common model contains records that are automatically created as a result of a certain type of transaction, like an Invoice, and records that are manually created against a company’s ledger. The lines of a given JournalEntry object should always sum to 0. A positive net_amount means the line represents a debit and a negative net_amount represents a credit.
