WORKING WITH LONGSEN
Clear responsibilities.
A direct conversation.
Who are these services for?
Our promotion services are for e-commerce merchants and brands looking to introduce their products to relevant audiences. Share your store URL, products and target markets so we can discuss your requirements.
What does the merchant pay for?
The merchant pays Longsen a commission calculated as a percentage of sales revenue, using the rate and data source agreed for the campaign. Cancelled and refunded orders are deducted from commissionable sales. Billing is in USD. Service commissions and reimbursement of advertising costs are due within 7 business days after the campaign ends.
Who pays the advertising platforms?
Longsen advances advertising costs on behalf of the merchant within the agreed campaign budget. The merchant reimburses the advertising costs actually incurred, separately from the sales-based service commission. Unspent budget is not an incurred advertising cost.
Who handles product orders and customer support?
The merchant handles product purchases, fulfilment, product returns and consumer support through its own sales channels. Longsen’s role in this service is product promotion; we do not collect consumer payments for the merchant’s products.
What happens if services are not completed?
If Longsen does not complete the agreed promotional services, Longsen refunds 50% of the total service fees already received for that engagement. A lower-than-expected sales result alone does not constitute incomplete service. This refund applies to service fees, separately from advertising costs.
Advertising costs already incurred or irrevocably committed are non-refundable and remain payable by the merchant. Any advertising funds received from the merchant that remain unused after incurred and irrevocably committed costs are accounted for are refunded in full. Where Longsen has advanced the advertising costs and no unused advertising funds have been collected from the merchant, there is no unspent budget balance to refund.
How do cancellation and refunds work?
Request cancellation or a refund by email with your company name, campaign reference and reason. On written confirmation of termination, no new advertising placements are made; accrued commissions and incurred or irrevocably committed advertising costs are settled. Voluntary cancellation alone does not trigger the incomplete-service refund.
We review refund requests within 7 business days of receiving complete information. Approved refunds are initiated to the original payment method within 10 business days of approval; receipt depends on your bank or payment provider. Read our service and refund terms for delivery review, eligibility and settlement details.
How do I discuss an existing engagement?
