In the dashboard, once you accept an order, it will be ready to be processed. You can always accept the order in advance even if the order is in the future, to indicate to customers that you accepted their order.
Once you click Start Preparing, the system will start to assign the order to delivery riders. It will take from few seconds up to 30 minutes for the order to be accepted by rider, and arrived for pickup at your premise. You can click on the Assigning Rider... button to refresh order status manually.
Please be aware that during peak time, it is very hard to be matched to any riders if the delivery price is low. We will try our best to make sure each orders get matched in less than 30 minutes. We can sometimes employ additional means like adding tips to the order, in order to get matched faster.
