bonsaiERP is a simple ERP multitenant system written with Ruby on Rails and includes the following modules:

• Sales
• Buys
• Expenses
• Bank and Cash Accounts
• Inventory
• Multi currency
• Multiple companies
• File management (in development)

The system allows to use multiple currencies and make exchange rates.

• Ruby 2.2.2
• PostgreSQL 9.4 and postgresql-contrib to enable hstore
• Nodejs for compiling assets
• imagemagick
• phantomjs

After installing the required (ruby, postgresql, etc.) you can begin with bonsaiERP, run

rake db:migrate

this will create all neccessary tables, if you are in ubuntu or debian edit yor /etc/hosts file and add something like this

127.0.0.1	app.localhost.bom
127.0.0.1	bonsai.localhost.bom
127.0.0.1	mycompany.localhost.bom

in development you will need to edit but in production you can configure so you won't need to edit the /etc/hosts file for each new subdomain, start the app rails s and go to http://app.localhost.bom:3000/sign_up to create a new account, to capture the email with the registration code use mailcatcher. Fill all registration fields and then check the email that has been sent, open the url changing the port and you can finish creation of a new company.

The system generates automatically the subdomain for your company name with the following function name.to_s.downcase.gsub(/[^A-Za-z]/, '')[0...15] this is why you should have the subdomain in /etc/hosts

bonsaiERP uses dragonfly gem to manage file uploads, you can set where the files will go setting:

config/initialiazers/dragonfly.rb
