FAQs
GSMA has initiated an intra-group reorganisation project to optimise our legal structure. The service is moving to this new entity as a result of this. Please note that the new entity name was formally ServiceCo UK Ltd, but is now GSMA Advisory Services Ltd
We will be contacting you in advance for any GSMA Services that you currently participate in if they are impacted. Your GSMA Membership will not be impacted and will continue to be invoiced by GSM Association.
Unfortunately no, the invoice for your service will now be issued by GSMA Advisory Services Ltd going forward.
Your Membership invoice will continue to be issued by GSM Association.
The invoicing amount and currency is determined by the contract which means that, unfortunately, we are unable to change the currency of the invoice.
The payment must be made in accordance with the invoice. This means that you cannot pay in a different currency. If there are exceptional restrictions which prevent you from doing so, please contact creditcontrol@gsma.com for further advice.
The correct bank account details relating to the service will be displayed on your invoice. Please check your invoice and the bank account details carefully.
Your payment must match the bank details from the invoice you receive. Please ensure when you make a payment, you check the bank details on your invoice to ensure you are paying to the correct GSMA bank details, the correct currency and full value of the invoice. Any fees that are outstanding could result in a delay to your subscription/ service access or suspension.
Our preferred method is wire transfer. We do not accept cheques. If you are experiencing any difficulties sending a wire transfer, please advise us and we may be able to offer you a credit card payment option.
We are unable to issue pro forma invoices.
In case of any pricing queries, please contact your account manager.
You should advise us at the earliest opportunity if your company details have changed. Once the invoice is issued it cannot be amended. We will communicate with you prior to your annual renewal, this would be a good opportunity to advise us of any recent company detail changes.
Unfortunately, we are not able to sign any of our customers’ Code of Conduct due to potential clashes with our own terms and conditions, as agreed to your contract. Please note that we have our own Anti-Bribery, Anti-Corruption policy. You can view all of our legal policies at www.gsma.com/about-us/legal.
The addressee of the invoice must always be with whom we hold the contract. We are currently unable to support requests for invoices to be addressed to any third party.
Please contact creditcontrol@gsma.com immediately. We will be able to confirm if and where the payment was received. Please note that should there be an underpayment as a result, you shall be liable to pay the difference. If your payment was sent tosomeone other than the GSMA due to fraud, it is your responsibility to recover the funds. The GSMA cannot be held responsible, and you will still have an obligation to pay by the invoice due date whilst you recover the funds.
Due to our company tax-exempt status as a non-profit trade association, we are unable to reclaim any WHT deductions made on our invoices. Our terms and conditions state that invoices must be paid in full without deductions of any kind and therefore, your invoice will be grossed up by the percentage of WHT applicable.
If you require a PO to be quoted on the invoice, we require the PO number to be advised in advance in order to issue the invoice. The PO deadline has been communicated in the renewal communication. It is important to note that to avoid any delays to your renewal and avoid service suspension, please ensure that your POs are raised correctly and submitted by the deadline date. Please ensure that your PO is: Registered to the correct entity as per any signed contract with GSMA
- Issued with the correct currency and denomination
- Membership – GSM Association in the UK
- GSMA Device Database – GSMA Ltd in the USA
- GSMA Intelligence – Speak to your account manager
Communications for PO approvals will be sent in good time for these to be reviewed, raised and approved. Please also be aware no invoice date can be amended.
No, invoice dates cannot be amended once issued. Once raised, invoices are legal documents that are final, and any request to change an invoice date to match a PO will not be supported. This falsifies accounting not just for the GSMA, but also your internal accounting team which could lead to fines for both parties.
If you require your invoice to be submitted on a portal please advise which one and check that you are already connected to theGSMA on that portal. If not already connected, please provide a connection link to billing@gsma.com stating the GSMA Entity. Note: GSMA cannot absorb any external portal fees, should you request to submit an invoice via a portal that includes annual subscriptions, or fees for uploading the invoice, these fees must be paid by yourselves (the customer) without deviation. If these fees cannot be paid by yourselves (the customer) please arrange for the invoice to be processed outside of any given portal request.
We are, unfortunately, unable to facilitate this request. If you are subscribed to more than one service, then you shall receive a separate invoice for each one.
Failure to settle your invoice(s) by the due date may result in suspension. You may also incur late payment interest charges as perthe terms and conditions. Once suspended it will not be reactivated until full payment is received including payment of any interest.
