Invoice Payments Received

Is it possible to settle an invoice by taking the money from an existing QBO account, such as the Bank Current Account?

I do the finances for a community hall, which is booked by external users. Those bookings are billed through QBO by raising an invoice. The hall has a cafe and sometime users settle their room hire invoiceat the cafe till. The till roll is then added into QBO on a daily basis & all the money received goes into the Bank Current Account.

But that money can therefore contain money paid in to settle a room booking.

So is it possible to settle an invoice by taking the money out of the QBO Bank Current Account?

THANKS !
