In March 2013, my wife and I opened a cupcake store (www.bitemecompany.com) and I went looking for a point-of-sale (POS) solution that could work offline, but synced data with the cloud as often as possible. I also wanted something that was easy to use for our sales people, and easy to customize and deploy for me. Disappointed by the available options, I decided to write my own - we now have an elegant, usable system that continues working even if completely offline, but also provides us with real-time stock & revenue reports via Google Spreadsheets when online.
My talk will cover 3 broad areas:
The Design & Usability of POS systems in general and how we created a minimal, elegant UI that requires little to no training.
Operational deployment & future possibilities. Our deployment process is very simple - the main POS is a self-contained, local HTML file that gets synced through Google Drive. Future possibilities include a built-in loyalty program and lightweight CRM/social media integration.
I will also try to clean up and make the storage/syncing part of the code available at the conference.
