Express Invoice is a free tool that allows you to issue an invoice to prove the sale of a set of items or the provision of a particular service.

The invoice is saved in the history and can be viewed at any time. It is also possible to find things that have not been paid so far.

Invoices can be assigned to various collectors and companies. Each company has its own billing history. You can also save company customer relationships and items for sale in the program.

If a customer decides to pay an invoice, Express Invoice can be used to update their status based on the amount donated.

You can customize the appearance of the invoice, including the company logo, symbols used as thousands and decimal delimiters, header and footer notes, and more.

In addition, Express Invoice can be used to generate a variety of reports with detailed information such as open invoices, per-vendor invoices, and per-item sales.
