I use a point-of-sale system ("RetailExpress") in my retail clothing shop. This system has a database that contains all product info, brand name, price, etc. RetailExpress sells a Magento plugin that allows synchronisation of products/customers/orders between the RetailExpress database and the Magento database.
The plugin allows manual bulk synchronisation for your first import (which makes use of [url removed, login to view]) and a crontab entry. My ISP has set up this cron entry to execute every 20mins.
Plugin user guide: [url removed, login to view]
Product quantities and prices are meant to sync every 200secs. This is not happening. When I schedule a manual sync within Magento, it executes. But none of the products' seem to update without doing a manual sync, i.e. from the cron schedule or otherwise.
I'm not sure if the problem is with cron, RetailExpress or Magento. I've emailed RetailExpress but they are very difficult to work with.
I'm getting desperate and need help!
Let me know your thoughts.
