Can you create a "receive money" transaction that is oweing

BossSquadTraining

Hey there,

I run a small pt business and sometimes my clients will not pay the full bill upfront.

e.g. a session is $60 and they pay me $40 and I will get the rest of the cash next week.

Is there a way to put this transaction into reckon and have that clients account oweing, so I would be able to go to their account and see "ah, they owe me this much".
