Invoicing

Like Xero, but shittier.

Invoicing is an app for issuing invoices, track expenses and managing clients for all the sole traders of New Zealand. That are registered for GST. And can host a Rails app. And are able to configure Google OAuth.

Installation

Do the usual like installing gems with bundler. Apart from that you need to install wkhtmltopdf for PDF generation.

Mac OS run the following:

brew cask install wkhtmltopdf

Ubuntu:

sudo apt-get install wkhtmltopdf

When using versions 0.12.4 and higher wkhtmltopdf doesn't run in a headless mode anymore. You need to do something like:

sudo apt-get install wkhtmltopdf
sudo apt-get install xvfb
printf '#!/bin/bash\nxvfb-run -a --server-args="-screen 0, 1024x768x24" /usr/bin/wkhtmltopdf -q $*' > /usr/bin/wkhtmltopdf.sh
chmod a+x /usr/bin/wkhtmltopdf.sh
ln -s /usr/bin/wkhtmltopdf.sh /usr/local/bin/wkhtmltopdf
wkhtmltopdf http://www.google.com output.pdf

Google Authorization

Make yourself a project at Google Console. In that project, go to the "APIs & auth" tab, then the "Credentials" tab. Create a new client ID of application type "Web application". Set the Authorized Redirect URI to https://yoursite.com/google-callback. You might want to put in http://localhost:8080/google-callback so you can test locally too.

After that you need to create a config/database.yml
