GnuCash Portable allows you to track bank accounts, stocks, income, and expenses. As quick and intuitive as a checkbook register, it is based on professional accounting principles to ensure balanced books and accurate reports.

GnuCash Portable was initially aimed at developing capabilities similar to Intuit's Quicken application, but it also has features for small-business accounting (customers, vendors, jobs, invoices, accounts payable/receivable), double-entry bookkeeping system, and online banking with specific institutions (requires running as admin).

Installer, Linux, Mac, and Android versions are also available.

GnuCash Portable Features:

Bank/Liability/Expense Accounts

Stock/Bond/Mutual Fund Accounts

QIF/OFX/HBCI Import, Transaction Matching

Reports, Graphs
