we are service providers like machinery repairs and maintenance.

we provide food for department and they have paid that amount with 18% gst, and the hotel who are provided the food, have issued an invoice with 18% gst. can I show both invoices. i want to treat it as supply and I will pay the gst difference. is it correct?
