Subscription Service & Refund Policy

Subscription Service & Refund Policy — Big-O

The following terms apply to all subscription services provided by this platform. By reading the relevant information on the subscription page and clicking buttons such as "Start Using," "Subscribe Now," or "Confirm Payment," the user acknowledges having read, understood, and agreed to the entire content of this policy.

I. Plan Types and Billing Methods

This platform offers two tracks — Brand Website and E-Commerce — each with five tiers (Brand: Essential / Business Standard / Business Growth / Enterprise Pro / Enterprise Ultimate; E-Commerce: Commerce Lite / Commerce Standard / Commerce Advanced / Commerce Expansion / Commerce Ultimate). All plans provide the following:

1. Monthly Plan (No Contract)

  • Billed on a monthly payment basis.
  • No contractual period; cancellation is available at any time in accordance with this policy.
  • "Monthly Amount" refers to the standard monthly fee for the plan as published on the official website for the current period.

2. Annual Contract Monthly Payment Plan (12-Month Contract)

  • The contract period is 12 months, with monthly installment payments.
  • Entitled to a discounted monthly amount compared to the monthly plan (the "Annual Contract Discounted Amount").
  • Self-cancellation through the back-end is not permitted during the contract period; early termination requires payment of a penalty fee calculated in accordance with this policy.

3. Free Trial (entry plans only: Essential / Commerce Lite)

  • The entry plans (Essential or Commerce Lite) offer a 7-day limited free trial; in the free-experience initial questionnaire you choose to try the Brand or E-Commerce track.
  • The number of trial days, functional scope, and limitations shall be as disclosed on the website or promotional page.
  • If the user does not cancel before the trial expires, it will automatically convert to a paid plan and billing will commence.

II. Formation of Contract

  1. All subscriptions are completed through online processes; no paper or electronic contract signatures are required.
  2. By reading the plan details and this policy on the subscription page and clicking the activation button, the user agrees to and forms a valid contract.

III. Payment Methods and Auto-Renewal

  1. All paid subscriptions are processed through third-party payment services.
  2. The user authorizes this platform to automatically charge according to the plan cycle.
  3. Monthly plans: Automatically renewed and charged on each due date until the user cancels through the designated process.
  4. Annual contract monthly payment plans: Charged on a fixed date each month for a total of 12 installments; upon expiration, renewal or adjustment shall be made according to the terms announced at that time.

IV. Cancellation and Termination

(1) Monthly Plan (No Contract)

  1. The user may cancel the subscription through the member dashboard or designated interface before any billing date.
  2. After cancellation, charges cease from the next billing period; fees already paid for the current period are non-refundable and non-transferable.
  3. If cancellation is not completed before the billing date, the charge for that period will still be processed and no refund may be requested.

(2) Annual Contract Monthly Payment Plan (12-Month Contract)

  1. Self-cancellation through the back-end is not permitted during the contract period; early termination requires contacting customer service.
  2. Early termination requires payment of a penalty fee, calculated as follows:

Penalty Fee = (Monthly Amount - Annual Contract Discounted Amount) x Remaining Months

  • Monthly Amount: The standard monthly price for the same plan.
  • Annual Contract Discounted Amount: The discounted monthly price under the annual contract plan.
  • Remaining Months: The number of whole months remaining from the month of termination application to the end of the contract period.

The user must first settle:

  • Any due but unpaid installment fees; and
  • The calculated penalty fee, before termination can be completed.
  • All fees already paid during the contract period are non-refundable.

V. Refund Policy (No Refund Principle)

  1. This platform provides an instantly activated SaaS service; access is granted immediately upon payment. Accordingly, refunds are not provided under any circumstances.
  2. Refunds or credits may not be requested on the grounds of non-login, non-use, or accidental operation.
  3. In the event of credit card chargebacks or payment disputes, this platform reserves the right to suspend the account and pursue recovery.
  4. In the event of a significant system anomaly resulting in prolonged service unavailability, this platform may compensate by extending the service period or other means; however, the method of compensation shall be determined solely by this platform and does not constitute a refund obligation.

VI. Commencement of Service and Applicability of Refund Policy

  1. Once the member has access to platform features and system services during the subscription period, the service is deemed to have been provided. Whether the member actually uses the service thereafter does not affect the applicability of the refund policy.

VII. Payment Processing and Data Protection

  1. General users only need to provide necessary information at the time of payment; no additional payment authorization documents are required.
  2. Business users who need to apply for a third-party payment account must provide information as required by the payment provider; this platform will provide assistance in accordance with established procedures.

  2. Free services do not guarantee stability, backup, or technical support.
  3. This platform may discontinue or adjust free service offerings at any time.
  4. Advanced features, additional capacity, or extended data retention require upgrading to a paid plan.

IX. Amendment of Terms
