Article Processing Charge
Open Access Commitment: All articles published in our journals and proceedings are open access and freely available online immediately upon publication. We guarantee that no university library or individual reader will ever have to pay subscription or pay-per-view fees to access our content.
To sustain this model, we apply an Article Processing Charge (APC). This fee covers the range of publishing services we provide, ensuring high-quality production and dissemination.
APCs become payable only after a manuscript has received editorial acceptance in principle following peer review. Formatting checks will commence once the fee is paid.
* Authors will be charged according to their country's economic classification (GNI per capita). Please refer to the World Bank List for official data.
Detailed payment instructions will be sent to the corresponding author immediately upon acceptance of the manuscript. We support the following secure payment methods:
Security Recommendation: For enhanced security, we highly recommend using PayPal. As a global leader in online payments (available in 190+ countries), PayPal ensures that your credit card details are never exposed to SOAP (the publisher), minimizing the risk of unauthorized use.
