Refund Policy

Effective Date: January 1, 2026

This Refund Policy applies to paid services provided by Sumhung HK Limited ("Sumhung", "we", "our", or "us"), unless a separate product policy, quotation, invoice, or written agreement states otherwise.

1. Billing Arrangements

Sumhung may support prepaid account credits, monthly invoicing, project-based billing, or other billing arrangements depending on the service type, customer status, and written agreement. The applicable currency, price, scope, delivery expectation, and billing method will be shown in the relevant quotation, invoice, checkout page, or service agreement.

2. General Refund Position

Completed services are generally non-refundable once delivered, performed, or made available.
Unused prepaid balances may be refundable upon request, subject to review, minimum threshold, payment processor limitations, and applicable law.
Billing errors caused by our systems will be corrected by refund, credit, or invoice adjustment.
Written agreements may define different refund, cancellation, or settlement terms.

3. Eligible Refund Scenarios

Refunds or credits may be issued in the following situations:

Duplicate charges for the same order or invoice.
Confirmed overbilling caused by a technical or administrative error.
Unused prepaid balance after account closure, subject to review.
Service not delivered due to a confirmed fault attributable to Sumhung.
Other cases required by applicable law or agreed in writing.

4. Non-Refundable Situations

Refunds are generally not issued for:

Services already delivered, performed, or consumed.
Work performed under a consulting, integration, support, or project arrangement.
Third-party costs already incurred on your behalf.
Fees resulting from incorrect information provided by the customer.
Service suspension caused by breach of Terms of Service or unlawful activity.
Refund requests made more than 60 days after the relevant charge unless required by law.

5. How to Request a Refund

Email support@sum-hung.com with the subject line "Refund Request".
Include your account email or company name, charge date, amount, invoice or order reference, and reason for the request.
Provide relevant evidence such as invoices, receipts, screenshots, or error records.

6. Processing Time

Review: Refund requests are normally reviewed within 3-5 business days.
Decision: We will notify you of the outcome by email.
Processing: Approved refunds are normally submitted within 5-10 business days.
Payment Method: Refunds are generally returned to the original payment method where supported by the payment processor.

7. Account Credits and Alternative Remedies

Where appropriate, we may offer account credits, service extensions, invoice adjustments, or other remedies instead of a monetary refund. The available remedy depends on the service type and billing arrangement.

8. Disputes and Chargebacks
