One chain, no re-keying
Estimate, order, challan and invoice carry the same lines forward.
Estimates, sales orders, delivery challans, invoices and receipts are stages of the same transaction rather than five separate documents. Each stage inherits what came before it, so the customer, pricing, quantities and tax treatment are entered once.

How it works
A practical workflow your team can follow without adding disconnected spreadsheets or repeated data entry.
Issue an estimate with agreed pricing, taxes and validity, and revise it until it is accepted.
Convert the accepted estimate into a sales order that reserves stock and records the commitment.
Raise the delivery challan, move stock out of the right warehouse, then invoice the delivered quantity.
Apply receipts against open invoices, handle returns through credit notes and watch the aging clear.
What you get
Sales and finance work from one record, delivery matches what was ordered, and nobody rebuilds an invoice from a challan by hand.
Estimate, order, challan and invoice carry the same lines forward.
Confirmed orders reserve inventory so it is not sold twice.
Deliver and invoice what is ready without closing the balance of the order.
Produce the challan the driver carries, linked to the order it came from.
See what is still owed to each customer across all open orders.
Compare selling price against item cost before the discount is agreed.
