These modules track the records affecting inflow of funds. More information can be found in the Invoicing and Receiving Money forums.
Orders are records that record sales. They generate revenue and accumulate costs. Management can view them with granularity for transaction-level budgeting and profitability analysis. The level of information and the tools available to users in the Orders module is controlled by access privileges.
Invoices record revenue to the General Ledger. Users can build invoices manually or they can use the tools available at the order level.
Receipt records are actual cash inflows. Receipt records are either applied to invoices (e.g., “Accounts Receivable”) or they are recorded against vendor refunds (Purchases). Receipts can also be applied directly to one or more General Ledger accounts. For example, a deposit from an owner might be recorded against the Owner's Capital Investment account.
