Dispatch, where the paperwork matches what went on the truck.
Packing against the sales order, challan and e-way bill from the dispatch, and an invoice that cannot disagree with either.
Dispatch is the last place an order can go wrong and the first place a customer notices. The goods leave, the challan is written at the gate, the e-way bill is generated on a portal, the invoice is raised in the office — four documents, produced by three people, from information that is only sometimes the same.
The failures that follow are small and constant. A quantity on the challan that does not match the invoice. An e-way bill with the wrong vehicle. A part-shipment that nobody recorded as partial, so the balance is either shipped twice or never. None of them are dramatic; together they are why the sales team spends its mornings on reconciliation.
Making the dispatch the source record removes the mismatch by construction, which is the one thing dispatch management software has to do well. What is picked and packed is recorded against the sales order. The challan and the e-way bill are generated from that record. So is the invoice. If a part-shipment goes out, the balance stays open on the order, visible to everybody, until it ships.
What you get
Pick against the order
What ships is selected from the sales order, so the balance quantity is known rather than inferred from what was invoiced.
Delivery challan
Generated from the dispatch, carrying the same quantities the invoice will, so gate and office cannot describe two different consignments.
E-way bill details
Consignment, value and transport details prepared from the dispatch record rather than re-keyed from a printout.
Part-shipments handled
A partly shipped order stays open with its balance, so nothing is shipped twice and nothing is forgotten.
Installation handover
Where a machine needs installing, the dispatch flows into a scheduled installation and the warranty clock starts from a recorded date.
Invoice from the dispatch
Billing raised from what physically left, which is what makes the quantity dispute impossible rather than merely rare.
The part-shipment problem
Very few orders ship complete on the first attempt, and part-shipments are where order tracking usually breaks. The customer has taken sixty of a hundred. Whether the remaining forty are in production, in stock, or already dispatched against a different challan is a question with several confident and contradictory answers inside the same company.
Keeping the balance on the sales order itself — reduced by each dispatch, visible to sales and production alike — turns that into one number. It also makes the customer conversation short, because the answer is specific: forty pending, thirty ready, ten in final inspection.
Why the challan and the invoice must share a parent
A challan is written when the goods move. An invoice is written when the goods are billed. In most businesses those are separate acts by separate people, and any difference between them becomes a dispute weeks later when the customer's stores and the customer's accounts compare notes.
When both are generated from the dispatch record, they carry the same quantities because they are reading the same row. It is a small structural decision that eliminates an entire category of recurring argument.
From dispatch to installation
For anybody shipping machinery rather than components, dispatch is not the end. The unit has to be installed, commissioned and handed over, and the warranty period runs from a date somebody needs to be able to prove. Carrying the dispatch forward into a scheduled installation means that date exists as a record rather than as a line in an engineer's notebook.
Questions people ask.
What does dispatch management software do?
It records what physically ships against a sales order, and generates the delivery challan, the e-way bill details and the invoice from that same record — so the documents describe one consignment rather than three versions of it.
Does it generate e-way bills?
The consignment, value and transport details are prepared from the dispatch record rather than re-entered, which is what removes the transcription errors that cause e-way bill mismatches.
How are part-shipments tracked?
The sales order keeps its balance quantity, reduced by each dispatch. An order that has shipped partly stays open with the remainder visible, so nothing is shipped twice and nothing is dropped.
Can dispatch trigger an installation?
Yes. Where the item needs installing, the dispatch flows into a scheduled installation and the warranty period starts from the recorded handover date.
Does the invoice come from the dispatch?
Yes, and that is deliberate. Billing what actually left, rather than what was ordered, is what makes the challan and the invoice agree.
