After-Sales Instructions
1. Design Cost
Design fees are project-specific, reflecting the unique circumstances and demands of each undertaking. We offer reasonable quotations in alignment with your precise requirements, ensuring transparency and fairness. Be aware that the product price may differ from your project's actual quotation.
2. Design Content
Ensure comprehensive communication of design requirements before commencing the project. Changes to the design post-initiation require customer service negotiation and potential fee adjustments. Accurate design-related materials are essential, as inaccuracies or omissions preclude free corrections.
3. Design Adjustment
Upon receipt of the design plan, carefully finalize it. Post-submission, designers are not required to modify or redesign but may offer complimentary fine-tuning within one month based on complexity. Difficult modifications will incur a designated fee.
4. Design Refund
Design services are bespoke, excluding eligibility for a seven-day unconditional return. Refund discussions or agreements should occur before accepting receipt of all drawings or source documents.
Once received, customers should securely store source documents, as the company holds no obligation to retain them. Every piece is the designer's labor of love, accomplished through dedication and hard work; we kindly request your understanding.
