Parcelforce Oversize and Overweight

 
Current Invoice Format

Currently, sales orders relating to both core product billing and any oversize or overweight items are displayed as a single line (example below):

 
Invoice Format from 24 September 2026 onwards

Separate sales orders for core product billing and any charges for oversize/overweight items will be listed separately to allow for greater clarity (example below):

Core Billing

 
Correction Charges for Oversize/Overweight will appear separately

 
Details of the items charged will be able to be viewed in two places:

• By either viewing the supporting Parcelforce Supplement available on eInvoicing: https://invoicing.royalmail.com/RMF/
• Alternatively, you can continue to access item level reports through Tracked Reporting, which is accessible via royalmail.com/oba 
• Help and support on how to use Tracked Reporting can be found here

 
Customers will be able to access item level information within a supplement document available on eInvoicing.

Supplements may be available before orders are invoiced and provide you with the necessary information to take action and avoid charges in the future.

The Parcelforce Supplement will list all the items charged within a specified Sales Order number, the original Sales Order that the item was billed against and any relevant dimensional or weight measurements which have been recorded.

For Parcelforce Worldwide customers, items over 220 litres or exceeding 1.5 meters in length or over 30kgs will be subject to a surcharge of £60 per item. Items over 500 litres, or exceeding 2.5 meters length or over 30kgs on the express48large service will be subject to a surcharge of £100 per item. For more information on how to calculate the litre calculation please visit parcelforce.com

Example of litre volume calculation

Parcel size = Length is 100cms, Width is 30cm and Height is 20cm.

100cm x 30cm x 20cms = 60,000cms, Litre Volume- 60,000cms/ 1000 = 60L
