Shiptheory will receive any of your orders within minutes of the order being created in your store. If Shiptheory receives the order while it's status is pending. The shipment will process as normal. If we receive the order after it has already been fulfilled, the order will appear in Shiptheory as Not Ready. This happens because we wouldn't want to process an order that has already been booked in and had tracking information assigned to it previously.
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.
