9. 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 September 30, 2025 and December 31, 2024, the outstanding balance of the advance from customers was $250,987 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.
