Adding up the money from other sources and the Sales revenue to get the total receipts

then you take the total receipts from the months and take it away from the total payments spent on supplies and staff

you then get the net cash flow, to find out the opening balance you start with the money you had and then add it on the net cash flow to get the closing balance

so for example, this screenshot shows that the business isn't supplying them with enough money to keep them going and there is a chance the bank will not invest in them so it is better to keep the money and close the business.
