All fixed price services listed on Crayfish.io are designed to offer you a combination of streamlined process, fixed deliverables and controlled cost. Any change of scope or deliverables may lead to a change of service as well as service provider. You will need to communicate with your service provider for any such changes. If the purchased service cannot meet your purpose, you will need to talk to our customer service team or submit a refund request before the service starts. You may still be charged for part of the services and expenses incurred once the service has been initiated. Please check our Terms of Service for details.
