Amazon Ad Fees - Charge Method vs Seller Account Method


Hope you’re all well. Aiming for a bit of advice regarding the below.

A few months ago we had a large Amazon campaign which we opted to use the ‘Credit Card Method’ in order to cover costs.

Since then we have been using the ‘Seller Account Method’ - ‘The easiest method to pay for Sponsored Products is to have the cost of campaigns deducted from your Amazon Seller Account’.

Now my understanding from that description implies that all ad fees will be deducted from Account Balance. If this is the case, why would I still be receiving charges via my credit card?

The only possible explanation I can think of is if ad fees correlate with disbursement date and Amazon have already moved the funds to my bank account, due to there being a ‘lack of funds’ on ‘balance’, they may have deducted ad fees directly from Credit Card despite not using this method? It seems odd that they would allow this option and yet so frequently transfer the money yet not leave enough to cover predicted ad fees. If this is the case, is there an option to leave a flat base of funds to cover all costs including refunds?

Honestly I’ve scoured the web trying to find a bit more in depth info regarding this and so far haven’t found anything that confirms any of the above. If only there was a number to call which I could talk to someone directly just to confirm.

Any info would be greatly appreciated.

Many thanks

The reason you might still be receiving charges on your credit card could be because there was a lack of funds in your Seller Account balance when Amazon tried to deduct the ad fees. In such cases, Amazon may automatically charge your credit card to cover the costs. This could happen if the funds from your Seller Account have already been transferred to your bank account.
