Hello @goodsquare
You would record the purchase of the train ticket as a normal purchase - create a purchase invoice assigned to a category like “Travel”.
You then have 2 options:
-
If it’s a brand new sales invoice (e.g. nothing has been created yet), you could rebill the cost and contra it, meaning the sales invoice will use the exact same nominal code (more info here: Rebilling Expenses). This will create a new sales invoice for you with the line already there.
-
You can use a nominal code such as General Sales
I hope this helps!
