  • Multiple customizable templates for invoices.

    • Rename the copy to any suitable name, making sure to preserve the .php extension and keep it in the same folder.
    • Edit the template in any code editor as you see fit.
  • Apply discounts and taxes.
  • Show invoice total in digits and letters.
  • Price history for items to keep log of price changes and apply the correct price to invoices based on their issue date.

This application was created using AppGini, and therefore it shares the features of any AppGini application as well, including:

  • Responsive Bootstrap apps that work beautifully on any device.
  • Support for multiple users and user groups, with easy-to-configure per-table permissions.
  • Quick and advanced search.
  • Export your data to CSV to work on them in Excel or other spreadsheets.
  • Import already-existing data from CSV files through a powerful import wizard.

Disclaimer: AppGini itself is not an open source application, but: 1. applications generated by AppGini can be distributed as open source with any license of choice. 2. You don't need to install AppGini in order to use this app.


Installation

This is a PHP/MySQL web application that you run from a browser. You can install it either locally on your own PC, or to a web/intranet server.

1. Trying it out using Gitpod (requires a github account)

This application is ready to run within the Gitpod IDE. This will allow you to try the application out and develop it for your needs. All you will need is a web browser. Do not use this in production!!!

Launch private demo on Gitpod

The app would take a couple of minutes to launch. Afterwards, you'll see the welcome screen of the app in the right part of the window, where you can start the setup wizard. When prompted to enter the database name, database username and datatbase password, you should enter appgini for all.

Gitpod is intended for previewing the app only, and is not suitable for use in actual production environments.


2. Installing to a PC

System requirements

This application can be installed on Windows, Linux and MacOS. Before installing, you should have the following software set up and running:

  • A webserver (Apache, IIS, nginx, ... etc)
  • PHP 5.6 or higher.
  • MySQL 5.6 and above; or MariaDB 10 and above.

If you don't have the above software installed, we recommend installing Xampp latest version.

Installation steps

  1. Download the latest release as a zip file. (Click the Source code (zip) link down the page).

  2. Extract the contents of the zip file. Then copy the contents of the app folder into a folder inside your document root. For Xampp on Windows, this is usually C:\xampp\htdocs (more info about how to find your 'document root').

  3. In your web browser, go to: http://localhost/app-folder/ (change app-folder to the name of the folder inside your document root where you extracted the zip in step 2).

  4. You should now see the setup wizard in your browser. Just follow the steps!

Installation steps

You can also perform more advanced customization, like adding reports, changing validation rules, adding business logic, ... etc. through hooks. Please refer to the AppGini hooks documentation for more details.
