After submitting the initial graphic design quote, it is important to establish a clear process for handling client requests and changes. Maintain open lines of communication with the client, promptly address their inquiries, and assess the feasibility and impact of requested changes. If the changes significantly affect the project scope or cost, provide a revised quote or estimate outlining the modifications and associated costs. Prioritize maintaining a collaborative and cooperative relationship with the client, ensuring that both parties are aligned and informed throughout the design process.
