Advance From Customer

10. Advance From Customer

 

For our operation, the proceeds received from sales are initially recorded as advance from customers, which was usually related to unsatisfied performance obligations at the end of an applicable reporting period. As of June 30, 2025 and December 31, 2024, the outstanding balance of the advance from customers was $271,173 and $368,232 respectively. Due to the generally short-term duration of the relevant contracts, most of the performance obligations are satisfied in the following reporting period.
