Refund Policy

Last updated: October 10, 2026

We provide software development and maintenance services under contract (business to business). Refunds follow the principles below; where a contract says otherwise, the contract prevails. This English version is provided for convenience. If it differs from the Traditional Chinese version, the Traditional Chinese version prevails.

1. When we refund

  • Duplicate or excess payments: if an invoice is paid twice, or more than the invoiced amount is paid, the excess is refunded in full.
  • Prepaid periods that have not started: for example, if next month's service fee was prepaid and the contract was terminated before that month began, that fee is refunded.
  • When we cannot perform: if, for reasons on our side, we cannot provide a service that has been charged, the unprovided part is refunded.

2. When we do not refund

  • Service months that have already started: monthly fees are charged per month; a month in which service has started is not refunded or prorated.
  • One-time fees for work that has been completed and accepted: for example, a build fee after the client has accepted the corresponding milestone.
  • Third-party costs already incurred: for example, cloud service costs paid on the client's behalf under the contract (pass-through items).

3. How to request a refund

Contact us by email (info@tenet-o.com) or through our LINE Official Account with your company name, invoice number, payment date and the reason. Once confirmed, we process the refund within 14 business days.

4. Refund method and fees

  • Refunds go back to the original payment method: card payments to the original card; ATM transfers to the company account you designate.
  • Refunds caused by us or by duplicate payments are made in full, and we bear the payment fees.
  • Refunds requested by the client and agreed by us are made after deducting payment-provider fees that have been charged and are not returned to us.
  • When the refund arrives depends on the card issuer or financial institution.

5. Invoices

Issued invoices are adjusted by a credit note or cancelled and reissued according to the refunded amount.
