Billing should be predictable, cancellable and clear before a customer pays.

This policy applies to standard XZMargin online subscriptions unless a signed order form or commercial agreement states different billing, cancellation or refund terms.

Document status

Effective date: 16 September 2026
Operator: XZ BYTECORE PRIVATE LIMITED
If a signed customer agreement conflicts with this public policy, the signed agreement controls to the extent of that conflict.

Free access and trials

Free analysis, trial access or promotional access does not create a right to a cash refund because no subscription fee has been charged for that free period. Feature limits and trial duration may change before a paid subscription begins.

Subscription billing

Paid plans may renew automatically according to the billing cycle shown at checkout or in the applicable order form. Taxes, payment-provider charges or statutory deductions may apply where required.

Cancellation

A customer may cancel an eligible recurring subscription using the available billing controls or the support/contact channel. Cancellation stops future renewal after the applicable paid period unless the product or commercial agreement states otherwise. Access may continue until the end of the already-paid billing period.

General refund rule

Except where required by law or expressly agreed in writing, fees for a billing period that has already started are generally non-refundable. This reflects continued reservation of service access, infrastructure and account capacity during that period.

Incorrect or duplicate charges

If XZ BYTECORE or its payment workflow causes a duplicate or demonstrably incorrect charge, contact us with the account, invoice/payment reference and amount. Verified billing errors will be corrected or refunded through the appropriate payment method.

Material service failure

If a paid feature is materially unavailable because of an XZMargin service issue and XZ BYTECORE cannot reasonably restore or provide the contracted service, the company may provide a credit, extension or refund as appropriate to the affected service and applicable agreement. This does not cover source-data errors, unsupported files, third-party outages outside contractual commitments or customer-side configuration failures.

Enterprise and negotiated terms

A signed order form, enterprise agreement, statement of work or reseller agreement may include different payment, minimum term, cancellation, service-credit or refund rules. Those written terms control if they conflict with this public policy.
