You can view your history of charges from your settings:
Under "Payments" you can then see and print out a history of your charges over time.
There are only 2 types of charges made on your registered payment method
1) For any storage, you use above 10GB (this include storage of the web versions of videos etc that we make when you upload)
2) For any Human Transcriptions you have ordered
The ID for each charge can help us resolve any issues you may have.
For Transcriptions, you can view exactly which video the transcription was done for by clicking "Item Details"
