In the daily manifest that is generated on your Shiptheory account, you can view how many of each service you sent and how much RM charged you for those. It's important to remember that you won't be able to see individual shipments on your RM account/site, only in your Shiptheory dashboard.
If you want to see and confirm the charges for your Royal Mail carriage, you can login to the Royal Mail OBA Website to view your Royal Mail invoices.
If you have any questions regarding your Royal Mail bill, please reach to our Royal Mail account manager.
