Open Source Point of Sale is a web based point of sale system. The main features are:

  • Stock management (Items and Kits)
  • Sale register with transactions logging
  • Receipt and invoice printing and/or emailing
  • Barcode generation and printing
  • Suppliers and Customers database
  • Multiuser with permission control
  • Receivings
  • Reporting on sales, orders, inventory status
  • Gift card
  • Messaging (SMS)
  • Multilanguage
  • Different UI themes

The software is written in PHP language, it uses MySQL (or MariaDB) as data storage back-end and has a simple but intuitive user interface.

The latest version 3.1.0 is a complete overhaul of the original software. It is now based on Bootstrap 3.x using Bootswatch themes, and still uses CodeIgniter 3.x as framework. It also has improved functionality and security.

Deployed to a Cloud it can be defined as a SaaS (Software as a Service) solution.

Server Requirements

PHP version 5.5 or newer is recommended (PHP 7.x is supported). Please note that PHP needs to have php-gd, php-bcmath, php-intl, php-sockets, php-mcrypt and php-curl installed and enabled.

MySQL 5.5, 5.6 and 5.7 are supported, also MariaDB replacement is supported and apparently offering better performance.

Apache 2.2 and 2.4 are supported. Also Nginx has been proven to work fine, see wiki page here

Raspberry PI based installations proved to work, see wiki page here

For Windows based installations please read the wiki and also existing closed issues as this topic has been covered well in all the variants and issues.

  2. Execute the file database/database.sql to create the tables needed
  3. unzip and upload Open Source Point of Sale files to web server
  4. Copy application/config/database.php.tmpl to application/config/database.php
  5. Modify application/config/database.php to connect to your database
  6. Modify application/config/config.php encryption key with your own

  2. Oops an issue? Please read the FAQ first thing :-)

Local install using Docker

From now on ospos can be deployed using Docker on Linux, Mac or Windows. This setup dramatically reduces the number of possible issues as all setup is now done in a Dockerfile. Docker runs natively on mac and linux, but will require more overhead on windows. Please refer to the docker documentation for instructions on how to set it up on your platform.

To build and run the image, issue following commands in a terminal with docker installed

docker-compose build
docker-compose up 

Cloud install

A quick option would be to install directly to Digitalocean using their preconfigured LAMP stack. Create a DO account first, add a droplet with preconfigured LAMP and follow the instructions for Local Install below. You will be running a provisioned VPS within minutes.

Cloud install using Docker

If you want to run a quick demo of ospos or run it permanently in the cloud, then we suggest using Docker cloud together with the DigitalOcean hosting platform. This way all the configuration is done automatically and the install will just work.

If you choose DigitalOcean through this link, you will get a $10 credit for a first month of uptime on the platform. A full setup will only take about 2 minutes by following steps below.

  1. Create a Digitalocean account
  2. Create a docker cloud account
  3. Login to docker cloud
  4. Associate your docker cloud account with your previously created digital ocean account under settings
  5. Create a new node on DigitalOcean through the Infrastructure > Nodes tab. Fill in a name (ospos) and choose a region near to you. We recommend to choose a node with minimum 1G RAM for the whole stack
  6. Click Deploy to Docker Cloud
  7. Othewise create a new stack under Applications > Stacks and paste the contents of docker-cloud.yml from the source repository in the text field and hit Create and deploy
  8. Find your website url under Infrastructure > Nodes > <yournode> > Endpoints > web
  9. Login with default username/password admin/pointofsale
  10. DNS name for this server can be easily configured in the DigitalOcean control panel

More info on maintaining a docker install can be found on the wiki

  • If a blank page (HTTP status 500) shows after search completion or receipt generation, then double check php5-gd presence in your php installation. On windows check in php.ini whether the lib is installed. On Ubuntu issue sudo apt-get install php5-gd. Also have a look at the Dockerfile for a complete list of recommended packages.

  • If sales and receiving views don't show properly, please make sure BCMath lib (php-bcmath) is installed. On windows check php.ini and make sure php_bcmath extension is not commented out

  • If the following error is seen in sales module Message: Class 'NumberFormatter' not found then you don't have php5-intl extension installed. Please check the wiki to resolve this issue on your platform. If you use WAMP, please read issue #949

  • If you installed your OSPOS under a web server subdir, please edit public/.htaccess and go to the lines with comment if in web root and if in subdir comment above line, uncomment below one and replace <OSPOS path> with your path and follow the instruction on the second comment line. If you face more issues please read issue #920 for more help

  • If the avatar pictures are not shown in Items or at Item save time you get an error, please make sure your public and subdirs are assigned to the correct owner and the access permission is set to 755
