Term	Definition
Accounts Payable	Contains all supplier transactions. Also known as A.P., the Creditors Ledger or Purchases Ledger.
Accounts Receivable	Contains all agent transactions. Also known as A.R., the Debtors Ledger or Sales Ledger.
AGP	Each Tourplan financial transaction has an Age Period (AGP) which determines which financial period in either the AR or AP ledger the transaction will be aged to—i.e., which column in the debtors or creditors ledgers Aged Trial Balance the transaction will appear in. The Age period is determined by an INI setting which offers the choices of ageing by Invoice Date, Booking Last Service Date, Payment Due Date or Travel Date. Once set, it must not be altered.
Closed Period	Any accounting period which has been finalised and "closed". Closing the period will prevent transactions from being dated in, or posted to that, or any prior period. Each ledger has its own Current & Closed periods.
Closed Transactions	Any invoice transaction that has been fully paid/receipted and all components of which are now in a closed accounting period.
Current Period	The accounting period in which the system is currently operating. Each ledger has its own Current & Closed periods.
Date of Travel Accounting	A method of accounting whereby all transactions posting to the General Ledger are dated relative to the travel date of the booking to which they belong.
Future Aged	An accounting transaction dated in, or prior to, the current accounting period, but whose AGP is greater than the transaction period.
Future Cash	Any case where cash has been received/paid and the transaction is dated prior to the age period of the invoice against which it applies.
Future Entered	An accounting transaction dated in a period greater than the current accounting period.
Future Expenses	Expenses (AP Invoices) that have been processed prior to a tour travelling.
Future Revenue	Revenue (AR Invoices) that has been raised in advance of the current General Ledger Period. Typically occurs when Tours have been invoiced a month or more prior to travel.
General Ledger	The accounting ledger where transactions from the Debtors and Creditors ledgers are consolidated. Also known as the Nominal Ledger.
GLP	Each financial transaction in Tourplan has a General Ledger Posting period (GLP) which determines which financial period in the General Ledger the transaction will be posted to.
Item	A collection of transactions relating to a single booking and identified by the Tour Reference. For non-booking transactions, the Item is the original Invoice reference.

Open Transactions	Any accounting transaction that has not yet been fully paid/credited.
Outstanding Vouchers	Any voucher that has been issued and for which a Supplier invoice/s has not been received or the voucher has not been paid and closed. In other businesses/accounting environments this would be an expected/contingent liability.

Tour Reference	A unique combination of Branch Code, Department Code and a 6 digit number that is assigned to a booking. This is used to identify and retrieve a booking and to collate transactions into "items".
Transaction Item	A grouping of transactions (invoices, Credit Notes and receipts/cheques) that pertain to the same booking. An Item's (booking) reference will match the Tour Reference.
TRP	Each financial transaction in Tourplan has a Transaction period (TRP). This is usually the current open period of the Subsidiary Ledger (AR or AP) in which the transaction is entered.
Unallocated Cash	Cash Receipts received and banked but not yet allocated to an invoice. Commonly used where cash is received prior to an invoice being raised.
