The billing address identifies the customer registration or purchaser to whom the invoice is addressed. The delivery address identifies where the goods are sent. Place of supply is a legal conclusion drawn from the applicable GST rule. These three can coincide, but they should remain separate fields because an instruction to deliver somewhere else does not necessarily change the contracting buyer.
Capture the parties before analysing the destination
Start with the order: who purchases, which GSTIN applies, who pays and who receives the goods? A head office may negotiate and pay while a branch receives stock. A customer may instruct direct delivery to its own customer. Record those roles in the order file instead of trying to compress them into a single address box.
Rule 46 generally requires the registered recipient's name, address and GSTIN or UIN, and it addresses delivery details and place of supply. Use clear labels such as “Bill to,” “Ship to” and “Place of supply.” Avoid a combined label that makes it impossible to tell whether an address belongs to the buyer or merely the receiving warehouse.
Apply the goods rule that matches the facts
For ordinary goods involving movement, section 10 of the IGST Act generally looks to where movement terminates for delivery. A qualifying bill-to/ship-to arrangement under section 10(1)(b) has a separate rule where delivery occurs on another person's direction. Installation or assembly at site also has a specific rule.
Do not select one of these routes merely from the presence of two addresses. Read the contract and direction to deliver. Two addresses may simply reflect a registered customer's principal place and another warehouse. Alternatively, three parties and two supplies may be involved. Document which supply your invoice represents before assigning its place of supply.
Illustrative registered-customer order
A Jaipur supplier receives an order from a registered Delhi dealer for equipment worth ₹80,000. The dealer directs delivery to a Haryana site. Assume the facts meet the section 10(1)(b) bill-to/ship-to conditions and the relevant place of supply for the Jaipur supplier's sale is Delhi. At an assumed confirmed 18% rate, IGST would be ₹14,400 and invoice total ₹94,400.
The invoice should still show the Haryana delivery details accurately. Replacing the delivery address with Delhi to make it “match the tax” would corrupt the physical movement record. The dealer's onward supply is a separate transaction requiring its own analysis; the supplier should not guess its tax treatment from the delivery instruction.
Review unregistered buyers under the specific provision
For goods supplied to an unregistered person, section 10(1)(ca), effective from 1 October 2023, requires its own review. It overrides the movement and non-movement clauses identified in that provision. CBIC Circular 209/3/2024-GST clarifies the case where billing and delivery addresses differ: the recorded delivery address determines place of supply in that situation.
For example, an unregistered customer provides a billing address in Delhi and orders goods for delivery to Karnataka. Record the delivery details and apply the circular's treatment rather than borrowing the registered bill-to/ship-to example. The circular also explains the treatment of the State name as an address for the provision. That should not become a reason to omit operational address details needed for actual delivery.
Keep service addresses out of the goods shortcut
A service invoice can name a billing address and an installation, property or event location without involving a goods movement. Section 12 of the IGST Act contains a general domestic service rule and several specific rules. For example, a service related to immovable property requires a different analysis from a general business support service.
Sales staff should identify the service and relevant locations before copying a customer's GSTIN State into place of supply. The customer may have a registered office in one State while the service concerns property in another. A written scope and service location help the accounts team select the appropriate provision.
Reconcile the destination with transport records
Compare the invoice's delivery address with the dispatch order, transporter instruction and applicable e-way bill details. Check postal code, State and recipient contact for operational accuracy. If a customer changes the destination after the invoice is issued, review both movement and tax consequences before editing any record.
Maintain the customer's original instruction and the approved change. A wrong delivery address can be a logistics problem even if the tax type stays the same. A changed destination can also reveal a different transaction structure. The review should explain which facts changed and whether the document and reporting need correction.
A courier contact address can differ from both the purchasing office and the legal delivery destination. Keep phone numbers and reception instructions in operational fields, while preserving the actual ship-to address. This avoids replacing a customer's warehouse with a logistics agent's office simply because the agent coordinates receipt.
Set a useful release control
A pre-issue address check should ask whether each field has an identified role, whether the purchasing GSTIN agrees with the order and whether the place-of-supply basis is recorded for unusual transactions. A mismatch should produce a specific question for sales, not an automatic substitution.
Once these roles are clear, the invoice can communicate both the commercial relationship and the actual destination. That makes it easier for the customer to process payment and for the warehouse to deliver correctly, while preserving the evidence needed to explain why the selected tax heads apply.
