1. Design Cost Considerations
When it comes to design fees, the unique circumstances and requirements of each project can vary significantly. As such, fees will adjust accordingly. We pledge to provide a reasonable quotation tailored to your needs. Please note, product pricing may not fully reflect the actual quotation for your specific project.
2. Design Content Specifications
Before commencing the design phase, please ensure all necessary content is communicated. Once design begins, changes are discouraged. Should alterations be necessary, contact customer service to discuss potential fees. Accurate design-related materials are crucial, as errors stemming from incorrect or incomplete information won't be corrected free of charge.
3. Design Adjustment Policies
Upon receipt of the design plan, carefully review and finalize the submission. Post-finalization, redesign or modification obligations cease for the designer. Free fine-tuning is available within one month, subject to complexity. Certain challenging modifications may incur a fee.
4. Design Refund Guidelines
Given the bespoke nature of design works, a seven-day unconditional return is not applicable. Refunds are negotiable before final confirmation of all drawings or source documents. Post-confirmation, refunds will not be entertained.
Upon receipt of the source document, it is vital that you maintain its safekeeping, as our company holds no obligation to retain copies. Each creation represents the designer's diligent efforts, often involving late nights and overtime, which we hope you'll appreciate.
