Payable/ Receivable adjustment

I am an accountant in a service sector. It is an expo of Veterinary medicines in Pakistan… I am receiving cash in advance and entering that cash into liabilities Head as " Services Payable to Expo Customers". The problem is when I am generating the sale Invoices its not debiting the liability head but crediting sales only… therefore my balance isn’t matching and creating disturbance. Please Help me out.
