It gets increasingly difficult as numbers get larger to read them without comma separated thousands. £10000000 is much more difficult to read than £10,000,000
On the Sage Help Centre it says that this is possible (As noted below) but the check box does not exist.
This would be a very useful fix.
To make it easier to read numbers when you are working with large numbers in Sage 50cloud Accounts, you can separate numbers by thousands with a comma.
That's it! Numbers are now separated with a comma, making it easier to read.
