After-sales Instructions
1. Design Cost
The design fee varies as the requirements and design complexity of each project differ. We promise to provide a reasonable quotation tailored to your specific needs, but please be aware that the quoted price may not match the actual project costs.
2. Design Content
Before commencing any design work, please ensure clear communication of all necessary design content, as changes are not permitted once the design process begins. If alterations are required during the design phase, contact customer service for a fee negotiation. Accurate design-related materials are imperative, as errors from incorrect or incomplete information will not qualify for free corrections.
3. Design Adjustment
Upon receiving the design plan, please review and finalize it diligently. Post-submission, designers are under no obligation to modify or redesign, though free fine-tuning is available within one month depending on difficulty. Complex adjustments may incur additional charges.
4. Design Refund
As design works are bespoke services, we do not support a seven-day no-reason return policy. Refunds are not accepted once the customer confirms receipt of all drawings or source documents, but negotiation or refunds may occur before final confirmation.
Once the source document is received, please ensure its safekeeping, as our company does not retain copies. Every project is crafted with the designer's hard work, often involving late nights and extra hours-your understanding is appreciated.
