Invoice & Important Billing Instructions

Billing Process

Two scenarios:
1/ Your institute (or you personally) is covering all your expenses (either by paying directly or through reimbursement). Only one invoice is issued.
2/ Your institute is covering only your registration fee and not the extra services, such as social events. Two separate invoices will be issued: one for the registration fee (addressed to your institute) and another for any additional booked services (addressed to you). Therefore, we require the correct billing details for both your institute and your personal address.

Please select the scenario that would apply:

1. My institute/ myself covers all my expenses.

2. My institute covers only the registration fee. Any additional costs will be paid by myself.

Billing Address

IMPORTANT:

Please ensure the billing address is entered correctly at the time of registration. Billing address cannot be changed after registration is completed.
If you require reimbursement from your institute or organization, it is your responsibility to confirm the correct billing address before registering.

Please note: Any amendments to billing details after submission may incur an additional administration fee.
