We run a small physical store, we also sell online with Shopify. This project is what we use to keep our shopify store up to date.

The flow is simple:

• create a scheduled task on our pysical store.
• the task runs an sql query and exports to .csv file.
• this project code takes the .csv as input.
• it compares the .csv to the shopify inventory and updates shopify as necessary.

It may prove useful as a starting point for others.
