10. Advance from Customer

 

For our operations, the proceeds received from sales are initially recorded as advances from customers, which are usually related to unsatisfied ¥ performance obligations at the end of an applicable reporting period. As of March 31, 2026 and December 31, 2025, the outstanding balance of the advance from customers was $212,899 and $213,127 respectively. Due to the generally short-term duration of the relevant contracts, most of the performance obligations are satisfied in the following reporting period.
