Sales and GST invoicing

One sales chain, from quotation to e-way bill

Q: What happens if I have to cancel an e-invoice?

An IRN can be cancelled within 24 hours of generation, and Unnati applies that limit for you. After the window closes, the correct treatment is a credit note against the original invoice, which the Sales module raises and Accounting posts to the ledger in the same step.

Q: Can I raise a delivery challan without an invoice?

Yes. A delivery order and a delivery challan can be issued on their own, which is what you need for goods sent on approval, for job work movement and for deliveries that will be invoiced later. The stock moves when the challan is issued, so the godown position stays correct.

Q: Does the batch number appear on the tax invoice?

Yes. The batch is carried from stock into the sales order and printed on the invoice and the delivery challan. Buyers in pharma, chemicals and food usually ask for this, and it is also what makes a later traceability question answerable in one search.

Every document knows the one before it, so nobody retypes a line and nothing drifts between the order and the invoice.

In short

Unnati runs the full Indian sales chain: quotation, sales order, proforma invoice, tax invoice with an IRN from the NIC portal, e-way bill, delivery challan and goods receipt note. Batches and prices carry forward document to document. Sales returns, credit notes and debit notes close the loop, and outstanding shows what is still to come.

The sales cycle

Seven documents, one thread

A quotation becomes a sales order, the order becomes a proforma, the proforma becomes a tax invoice with an IRN, and the goods leave with an e-way bill and a delivery challan. Item, rate, batch and tax carry forward at every step. Open any step below — this is the product, not a picture of it.

In more detail

How it works in practice

The screens in order, and what happens as a record moves through them.

Every document knows the one before it
A quotation converts to a sales order, the order to a proforma, the proforma to a tax invoice, and the invoice to a delivery challan.
E-invoice and e-way bill without a second portal login
Where e-invoicing applies to you, Unnati sends the invoice to the NIC service and brings back the IRN, the acknowledgement number and the signed QR code onto the printed invoice.
Price lists, targets and what is still outstanding
Rates in an Indian business are rarely one number.

Built for India

GST, e-invoice and the 24-hour window

The compliance rules are written into the documents rather than bolted on at the end of the month.

E-invoicing applies to businesses above the current turnover threshold — ₹5 crore at the time of writing, so check the latest notification for your case

An IRN can be cancelled within 24 hours of generation; after that the correction is a credit note, and Unnati enforces that rule

CGST, SGST and IGST are computed from the place of supply, with HSN carried from the item master

E-way bills are raised from the same invoice, with vehicle and transporter details recorded at dispatch

Questions

Sales: what buyers ask

Does Unnati generate an IRN and a QR code on the invoice?

Yes. Unnati connects to the NIC e-invoice service, submits the invoice and prints the IRN, the acknowledgement number and the signed QR code on the document. Who may generate or cancel an e-invoice is controlled per user, so a junior operator can raise a bill without holding the compliance action.
