To set up order batching for orders coming from the same table, go to

Stores > Store Settings > Operations

Scroll down the page to find Order batching. Click Enabled and select from 1 to 5 minutes - this is the time period an order from a table will be held on the cloud before being sent to your printer and EPOS system. If more than one order is placed from the same table during this time, you will receive the orders together.

Don't forget to press Save to apply the changes.
