One of the most complex tasks of an e-commerce business is to handle inventory and keep stock status up to date for all products.
Some of the challenges arise because the inventory is often managed by an external dropshipping warehouse or a few. Stock status may also change often and cause frustration to shoppers that find out their products are not available only at a later stage during checkout.
The best way to handle these types of situations is to implement custom scripts and rules to handle stock based on whatever information is handy in your available product feeds. Often if we are dealing with heavier load shops we will create a separate setup on another server that will handle stock-check throughout the day multiple times. Setting this up on a separate server will help with the load on the server of your actual shop and prevent slowdowns due to stock checks.
