Thanks for your suggestion. Any over payment will sit on a customers account but will not automatically be applied at the moment.
We could put in the option to do this, but it remains to be seen whether this would be a preferable option for our users moving forwards.
Some feedback on this would be great as to whether you would like KashFlow to have that control over applying payments automatically or would prefer to do this manually using bank feeds for example?
