A proforma invoice is a commitment to supply on stated terms, not a demand for payment of tax. It is used to get an advance, open a letter of credit or obtain a purchase order — and it carries no tax consequences at all, which is the whole point of it.

Getting an advance payment, opening a letter of credit, obtaining a purchase order, or giving a customer something to take to their finance department. It commits you to terms; it does not record a supply.
No supply has happened, so no tax is due and no input credit arises. Marking the document clearly is what stops a customer’s accounts department booking it as a purchase, which happens more often than you would think.
When the supply is made, a tax invoice is issued. If an advance was received against the proforma, the receipt and its adjustment against the eventual invoice both need recording.
It is a binding offer on the terms stated, for the validity period stated, but it is not a tax document. No GST liability arises from it and no input credit can be claimed against it.
No. Only a valid tax invoice supports an input credit claim, which is why a proforma should say plainly on its face that it is not one.
In practice very little, and the two are often used interchangeably. A proforma is typically more formal and more specific — used where the buyer needs a document for an advance payment or a letter of credit.
Not under the GST rules, since they are not tax documents, but you should — you will want to trace which proforma became which order and which invoice.
In tBiz the document becomes the next one without re-typing, against the same party ledger.
