When running reports like Trading summary some of tax the fields use hard-coding names instead of the name used / set by the client
Example "Inclusive Service Charge" could use the Name Field instead of the hard-coded Tax Field set by Tevalis.
Using the name field allows more flexibility without having to add in a new tax type to the systems.
The Math works in various other Countries/regions using the Service Charge tax type so having the reports pick up the name set by the user (which is used on receipts anyway) would make a logical full circle so receipts match the reports back of house.
