The Instacart online ordering integration is very simple. On the POS side, there is only one thing that needs to be done. We set up an item file export on your server that sends the item file up to Instacart once per night. This file includes some movement data that Instacart uses to help build your online ordering store. We've set this up in numerous stores, we set it up and forget it. It just works from that point forward. 

It's worth noting that Instacart charges a percentage of the transaction amount for their services. Many online ordering platforms charge a flat fee for online ordering. If you do a ton of online ordering, the flat fee option is better. If you do fewer online ordering transactions, the percentage of the transaction model may better suit you.
