After-Sales Instructions
1. Design Cost
Design fees are tailored to the specific nuances of each project, with variables such as project requirements and complexity affecting costs. We promise to offer an equitable quote that reflects your project's specific demands; however, the final product price may differ from the estimated fees provided.
2. Design Content
To ensure a seamless design process, please communicate all design requirements beforehand. Once design work commences, alterations are not permissible. Should any changes be necessary during the design phase, a negotiation with customer service is required for revised fees. Accurate design-related documents are crucial, as we do not offer free corrections for errors resulting from incorrect or incomplete information.
3. Design Adjustment
Upon receipt of the design plan, we urge clients to review it thoroughly. After finalization, our designers are not obligated to make modifications, though minor adjustments may be made at no additional cost within one month, provided the complexity allows. More challenging changes may incur additional charges.
4. Design Refund
Due to the personalized nature of design services, we do not offer a seven-day return policy. Refunds are not available once all drawings or source documents are confirmed as received. However, negotiations for refunds are possible before the final confirmation of receipt.
Upon receiving the source document, clients are responsible for its safekeeping, as our company is not liable for archiving. Each project embodies the dedication and hard work of our designers, who often work tirelessly, including late nights and overtime, to deliver exceptional results. We appreciate your understanding.
