Detailed Guides

Automatic Install/Update


You can use to migrate your data from InvoicePlane.

Manual Install

Step 1: Download the code

You can either download the zip file below or checkout the code from our GitHub repository. The zip includes all third party libraries whereas using GitHub requires you to use Composer to install the dependencies.


All Pro and Enterprise features from our hosted app are included in both the zip file and the GitHub repository. We offer a $30 per year white-label license to remove our branding.

Step 2: Upload the code to your server

Copy the ZIP file to your server and then check that the storage folder has 755 permissions and is owned by the webserver user.

cd /path/to/ninja/code
chmod -R 755 storage
sudo chown -R www-data:www-data storage bootstrap public/logo

Step 3: Setup the database

You’ll need to create a new database along with a user to access it. Most hosting companies provide an interface to handle this or you can run the SQL statements below.

CREATE USER 'ninja'@'localhost' IDENTIFIED BY 'ninja';
GRANT ALL PRIVILEGES ON ninja.* TO 'ninja'@'localhost';

Step 4: Configure the web server

See the guides listed above for detailed information on configuring Apache or Nginx.

Once you can access the site the initial setup screen will enable you to configure the database and email settings as well as create the initial admin user.


To remove public/ from the URL map the webroot to the /public folder, alternatively you can uncomment RewriteRule ^(.*)$ public/$1 [L] in the .htaccess file. There is more info here.

Step 5: Configure the application

See the details here for additional configuration options.

Step 6: Enable auto updates

Use this shell script to automate the update process.

You can run it as a daily cron to automatically keep your app up to date.
