A delivery challan is the document that travels with goods when the movement is not a sale, or not yet one. It records what left, from where, for whom and why, and it is the thing you will be asked for when somebody disputes a delivery.
A delivery challan is a document raised when goods physically move but the movement is not being treated as a completed sale at that moment. It travels with the consignment and records the items, quantities, the place the goods left, the place they are going, the reason for the movement, and who received them. It is not a bill. Nobody is being asked to pay because of it.
You need one in a small number of recurring situations: a demonstration unit going to a customer for trial, material sent out for job work or repair, goods sent on approval or on a sale-or-return basis, stock transferred between your own godowns, and despatches made before invoicing is possible. In each case the goods are out of your premises and somebody other than you has custody of them, which is exactly the situation in which a written, signed record earns its keep.
The two documents look similar and serve opposite purposes. An invoice says a sale has happened. A challan says goods have moved and the question of sale is still open.
A tax invoice is a demand. It creates a receivable, it carries the tax the customer is being charged, it enters your sales figures, and it is the document your accountant works from. A delivery challan creates none of that. It is a movement record and an acknowledgement, and the copy that comes back with a signature on it is the only evidence you will have if the customer later says four cartons arrived instead of five.
The practical consequence is about timing rather than paperwork. If you invoice at despatch for goods that may come back, you have recorded a sale that has to be reversed later. If you send goods with no document at all, you have no way to prove what left the building. The challan sits between the two: the goods are accounted for, the sale is not yet claimed, and the position is reversible without unwinding anything.
What the law requires on the document, when a challan is permitted instead of an invoice, and which movements need a separate transport document alongside it are questions with real answers under the GST rules. Those answers depend on the nature of the movement and on your own registration and state, so confirm them with your accountant or tax adviser rather than with a software vendor. What follows is about the workflow, not about what you are obliged to do.
The common thread is that in every one of these cases the goods are still, in some sense, yours. A business that does not track them ends up with a category of stock that is neither in the godown nor sold, which is where inventory differences quietly begin. That mechanism is described in why distributor stock never matches.
| Delivery challan | Proforma invoice | Tax invoice | |
|---|---|---|---|
| What it says | These goods have moved | This is what a sale would look like | This sale has happened, please pay |
| Travels with the goods | Yes | No | Usually |
| Creates a receivable | No | No | Yes |
| Goods may come back | Often the whole point | Not applicable | Only through a return and credit note |
| Typical use | Demo, job work, transfer, despatch before billing | Quoting a buyer who needs a document to raise a purchase order | Completed supply |
| What it becomes next | A tax invoice, a return, or both in part | A sales order and then an invoice | A payment, or an ageing entry |
A challan only works if the copy that returns is as carefully handled as the one that goes out.
The person despatching should be able to say, without asking anyone, what is going, to which address, under whose name, why it is moving, whether it is expected back and by when, and which order or contract it belongs to. The driver carries the challan itself and whatever transport documentation the movement requires, which is another point to settle with your accountant rather than to assume.
Somebody at the other end signs. That signature, with a date and a name, is the entire evidentiary value of the exercise, and it is the part most often lost. A signed paper copy that lives in a vehicle file is better than nothing and much worse than a signature captured against the record itself, where it can be found by customer, by item or by date two years later.
A challan is an open position. Either the goods come back, in which case stock returns and the position closes, or they are kept, in which case the challan becomes a tax invoice carrying the same lines. Doing that by retyping is how quantities and rates start to differ between the two documents. In Aura Business the delivery challan sits between the sales order and the invoice, reduces stock from the despatching location when it is raised, and converts to a GST tax invoice with the same lines when the sale is confirmed, so nothing is entered twice.
The challans worth reviewing weekly are the returnable ones. A demo unit at a customer site for four months is either a sale nobody has asked for or a machine that should be back in the godown earning money elsewhere, and in both cases the correct action is a phone call. Without a list of open challans, that call never happens.
A challan records that goods have moved and creates no demand for payment. An invoice records a completed supply, carries the tax charged and creates a receivable. Goods that may come back generally travel on a challan so that no sale has to be reversed later.
Yes, and that is the normal path once the sale is confirmed. The invoice should carry the same items and quantities as the challan. Raising it from the challan rather than retyping it is what keeps the two documents in agreement.
One raised for goods expected to come back, such as a demonstration unit, material sent for job work, or goods on approval. The quantity returned is recorded against the original challan, and only what the customer keeps is invoiced.
A movement record of some kind is needed so that stock leaves one location and arrives at the other in your books. Whether it must specifically be a delivery challan for your situation is a question for your accountant, as it depends on registration and the nature of the movement.
In practice: a serial number and date, your details and the recipient's, the despatch and delivery addresses, a clear description of the items with quantities, the reason for the movement, and space for the receiver's signature. Ask your accountant to confirm the statutory particulars for your case.
Keep every returnable challan open until it is either returned or invoiced, and review the open list regularly. Where the item carries a serial number, tracking it at unit level tells you exactly which machine is at which customer. See delivery challan software.
