Every transaction must debit one account and credit others by an equal amount. This ensures the books balance: the difference between income and expenses exactly equals the sum of assets and liabilities.

The GnuCash checkbook-style register provides a custom, convenient and familiar interface to entering financial transactions.

The register supports common checking and credit-card transactions, as well as income, stock and currency transactions. The following features are also provided:

• La posibilidad de introducir transacciones divididas
• La posibilidad de marcar una transacción como compensada o reconcilidada
• Relleno automático de las transacciones introducidas
• La posibilidad de mostrar varias cuentas en una única ventana de registro
• Una barra resumen que muestra toda la información relevante acerca del saldo de la cuenta
• Diversas opciones para personalizar la apariencia del estilo visual

You can create recurring transactions with a high level of customization of amounts and timeline. You can also set an automatic reminder when a transaction is due.

An assistant that runs when GnuCash is started allows scheduled transactions to be postponed without canceling or entering them before the due date.

GnuCash has an integrated module to display graphs of your financial data in the form of:

• Gráficos de barras
• Gráficos circulares
• Gráficos de dispersion

GnuCash also comes complete with a full suite of standard and customizeable reports, such as:

• Hoja de balance
• Ganancias & pérdidas
• Valuación de cartera
• y muchos mas.

Graphs and reports can be highly and easily customized in appearance and contents, in order to fullfill every user's need.

Account reconciliation allows the user to compare the transactions entered in an account against a bank statement. This operation is very useful to spot untracked transactions or data entry errors and ensure that your books match the bank's.

The GnuCash reconcile tool with running reconciled and cleared balances makes reconciling against bank statements an easy task.

Income/Expense Account Types (Categories) allow you to categorize your cash flow. When used properly with the double-entry feature and equity accounts, these enable you to generate reports, such as Profit & Loss, that plain-vanilla systems cannot handle.

Simplify managing a small business with Customer and Vendor tracking, Jobs, Invoicing and Bill Payment, and Tax and Billing Terms.

Using A/Receivable and A/Payable accounts you can even manage payrolls for your employees.

GnuCash gives you also a tool to manage your business' budget so that you can easily plan your financial strategy.

Different accounts can be denominated in different currencies. Currency movements between accounts are fully balanced when double-entry is enabled.

Track stocks individually (one per account) or in portfolio of accounts (a group of accounts that can be displayed together).

Get Stock & Mutual Fund quotes from various web sites, update portfolio automatically. Additional pricing sources are added regularly.

GnuCash by default stores data in an xml format. Starting with version 2.4, GnuCash financial data can be stored in a SQL database using SQLite3, MySQL or PostgreSQL.

Note this feature is considered experimental. It works for most of the common use cases but some corner cases have been reported to result in data loss. The GnuCash developers fix each issue as it gets reported. There is however no full test coverage so there may still be scenarios left that result in data loss.

GnuCash is also the first free software application to support the OFX (Open Financial Exchange) protocol that many banks and financial services are starting to use.

A transaction matching system ensures that duplicate transactions are accurately recognized and automatically deleted during file import.

GnuCash is the first free software application to support the German Home Banking Computer Information protocol, allowing German users to perform statement download and initiate bank transfers and direct debits.
