1. No payment is required when a manuscript is submitted or while it is undergoing peer review.
2. After formal acceptance, the corresponding author receives an official invoice or payment instruction from the journal/publisher.
3. Payment must be made only through the official payment channel stated in the invoice.
4. The article enters final production after payment verification, subject to the journal's production schedule.
5. Authors should retain proof of payment for administrative verification.

Payment of the APC does not guarantee acceptance and must not influence editorial or peer-review decisions. Manuscripts are assessed on scholarly merit, originality, methodological quality, ethical compliance, and relevance to FUADUNA's scope. Editors and reviewers do not receive authority to alter decisions because of an author's ability or willingness to pay.

Waivers: FUADUNA currently does not operate a general APC waiver policy. Any future waiver scheme must be publicly announced and applied independently of editorial decision-making.

Refunds: once payment has been verified and production has begun, the APC is generally non-refundable. Refunds may be considered for duplicate payments or an administrative error attributable to the journal or publisher.
