Shiptheory will receive any of your orders within minutes of the order being created in your store. There's a setting within your Shiptheory Squarespace settings that determines what status we look for when searching for new shipments, by default this is set to pending.
If you're unsure what the status of your order is within Squarespace you can see it in the status column by navigating to the orders page (home -> commerce -> orders)
If your orders aren't coming through to Shiptheory, please get in contact with our support team who will be happy to help you out.
