Accounting software is computer software that records and processes accounting transactions within functional modules such as accounts payable, accounts receivable, payroll and trial balance. It functions as an accounting information system. It may be developed in-house by the company or organization using it, may be purchased from a third party, or may be a combination of a third-party application software package with local modifications. It varies greatly in its complexity and cost.

Since the mid 1990s, the market has been undergoing considerable consolidation, with many suppliers ceasing to trade or being bought by larger groups, notably by Sage and Microsoft.

Modules

Accounting software is typically composed of various modules, different sections dealing with particular areas of accounting. Among the most common are:

names may differ by vendor

• Accounts payable—where the company enters its bills and pays money it owes
• Accounts receivable—where the company enters money received
• Billing—where the company produces invoices to clients/customers
• Collections—where the company tracks attempts to collect overdue bills (sometimes part of accounts receivable)
• Expense—where employee business-related expenses are entered
• General ledger—the company's "books"
• Inquiries—where the company looks up information on screen without any edits or additions
• Payroll—where the company tracks salary, wages, and related taxes
• Reports—where the company prints out data
• Time—where professionals (such as attorneys and consultants) record time worked so that it can be billed to clients
