If you click on Help top menu in Sage, you will see short cut keys listed its a drop down menu, I dont think there is any special process to get the job done, you just input the info as you have it. I generally find that a bank rec, of all transactions squares things up, obviously you post sales and purchase invoices first, this should ty up with cheque payments and customer recp. and cash payments, incidentals you have purchased with cash would go through petty cash to the correct nominal code hope thishelps I have tried to keep it simple gaynor
