Place of Supply Rules

Dear All,

Suppose We purchase goods Directly From the Supplier ( Hand Delivery) , can we put request to Supplier to raise the Invoice on our Different GST Number ( Branch Located in Gujarat) . Recently One Supplier refused to raise the Invoice citing reason that we sold goods in Maharashtra , So he will not able to charge IGST  since the Place of Supply is in Maharashtra.

Kindly throw some lights on Place of Supply Rules.
