1. I’m trying to pay the invoice online, but I’m getting a payment error. What should I do?

Below are some payment troubleshooting suggestions:

-Ensure your credit card is authorised for international transactions.

-If you are unable to access https://ijs.tspsubmission.com/, please try using a different web browser (if available), or try disabling any add-ons in your browser that might be blocking the transaction.

-Check if your credit card has a spending limit.

-If the page returns an error after entering your credit card details, your card provider may have blocked the transaction. To resolve this issue, you will need to contact your credit card provider.

-International credit cards often require a two-factor authentication process, such as 3D Secure, for international transactions. This may involve verifying your identity with the card issuer by providing a code sent via SMS or email. You may be required to complete both steps in the process before payment can be authorised.

If you are unable to resolve the issue, please contact the journal editorial office for further help.

2. Can someone else pay my invoice?

Currently, only submitting authors are allowed to pay the invoice.

3. How can I modify information in my invoice?

To update the invoice information in TSP Submission System, submitting authors can click the “Invoice” button, and modify information in the new webpage of invoice detail.

4. Which currencies do you accept?

We currently accept payments in US Dollars (USD).

5. Does TSP offer any discounts or waivers on the APC?

TSP offers APC discounts to selected reviewers. Please contact the journal editorial office for further information.

6. I have already paid my invoice, but it is still shown as “Awaiting Payment” / “Payment Confirmation Pending” in TSP Submission System. What should I do?

Please note that it may take several days for a bank transfer to be registered. If your payment was not confirmed after two weeks, please send a valid proof of payment to the journal editorial office.

7. What if I accidentally pay more or less than the invoiced amount?

If your initial payment was incomplete, additional payments are accepted to cover the remaining invoice amount.

In case you accidentally pay more than invoiced by TSP, please contact the journal editorial office, and we will refund the overpaid amount.

8. How can I apply for a refund of the APC if my paper is retracted?

Please note that APCs will not be refunded due to the retraction of an article.

9. How can I apply for a refund of the APC if my paper is accepted?

If a paper has been accepted, the payment is non-refundable. In the event that a manuscript is withdrawn by author request after it has been accepted any payment made may only be used as credit on a future submission.

10. Do I have to pay if my manuscript is rejected?

No. TSP only sends the invoice for article processing charges (APC) if a manuscript has been accepted for publication.

11. My question is not on the list.

Please contact the journal editorial office for further questions. If your paper has already been submitted, please indicate your invoice/manuscript ID.
