Dhanalakshmi Industries case study

Dhanalakshmi Industries manufactures, dispatches and invoices — and, like every Indian manufacturer, has to produce an E-Way Bill before the vehicle leaves. Before this project, each of those steps lived in its own process.

The work was to make them one chain: a quotation becomes an order, the order drives manufacturing and dispatch, and invoicing and the E-Way Bill come from what actually shipped.

Definition

What we implemented for Dhanalakshmi Industries

Dhanalakshmi Industries runs quotation, manufacturing, dispatch, invoicing and GST compliance as one connected process on a customised Odoo ERP. E-Way Bill generation is automated against the GST integration; quotations, proforma invoices, tax invoices and delivery documents are produced in the company’s own format; quotation revisions are version-tracked; invoicing is delivery-based with consolidated billing; and manufacturing shortages and bills of materials are managed against real stock.

Automating the E-Way Bill is the step manufacturers feel immediately, because it sits between the goods being ready and the vehicle leaving. Everything else on this project made that step possible by ensuring the dispatch record was already correct.

E-Way Bill: The statutory document for goods in transit. Generated from the dispatch, not typed again.
Delivery-based invoicing: Billing what actually left, so a part dispatch invoices correctly.
Quotation revision: A new version of a quote with the previous ones kept. What a disputed price is settled against.
Shortage: A component the BOM needs and stock does not have. Better known before the order is released.

The challenge

What was not working at Dhanalakshmi

Quotations, manufacturing, dispatch, invoicing, E-Way Bill generation and inventory were handled through separate processes. That produced delays, duplicate work and limited operational visibility, and the business needed one platform connecting sales, manufacturing, logistics, finance and compliance.

Documents were produced separately
Quotation, proforma, tax invoice and delivery documents were each prepared on their own, which is duplicate work and a source of inconsistency between them.
E-Way Bill was a manual step
Generating the statutory document by hand at dispatch is slow at exactly the moment a vehicle is waiting.
Quotation revisions were hard to track
Without version tracking, which price was agreed and when becomes a matter of recollection.
Invoicing did not follow delivery
When billing is not driven by what actually shipped, part dispatches and consolidated billing both become manual exercises.
Shortages surfaced late
Manufacturing shortages and BOM gaps were found during production rather than before the order was released.

What we built

What the implementation covered

The implementation joined those processes rather than improving each one separately.

E-Way Bill automation

Automated E-Way Bill generation with GST integration, produced from the dispatch record rather than re-entered into a portal while a vehicle waits.

AutomatedGSTAt dispatch

Business documents

Custom quotation, proforma, tax invoice and delivery documents in the company’s own format, generated from the same data rather than prepared separately.

QuotationProformaTax invoice

Quotation revisions

Revision management with version tracking, so what was quoted, when, and at what price is a record rather than a recollection.

VersionsTrackedAuditable

Delivery-based invoicing

Invoicing driven by what was actually delivered, with consolidated billing where several dispatches belong on one invoice.

Delivered qtyConsolidatedAccurate

Supply status

Supply status and delivery readiness monitoring, so the question of whether an order can ship is answered from the system.

Manufacturing and BOM

Manufacturing shortage and bill of materials management, so component gaps appear before the order is released rather than at the machine.

How it works now

How Dhanalakshmi runs on Odoo today

Sales, manufacturing, dispatch, invoicing and compliance now run as one chain, with the statutory document produced from the dispatch rather than alongside it.

E-Way Bill generated automatically
the statutory document comes from the dispatch record, so the vehicle is not waiting on data entry.
One source for every document
quotation, proforma, tax invoice and delivery note are generated from the same data in the company’s own format.
Quotation revisions kept
every version is tracked, so an agreed price is a record rather than a memory.
Invoicing follows delivery
part dispatches bill correctly, and several dispatches can be consolidated onto one invoice.
Shortages visible before release
BOM requirements are checked against real stock rather than discovered in production.

Results

What changed

What the client reports back, in their terms. We publish no percentages here because the project did not measure any, and a number we cannot stand behind is worth less than one we can.

Compliance without the delay

Automated E-Way Bill generation removed a manual step from the point where it cost the most time.

Consistent documents

Quotation through to delivery note now comes from one set of data in one format, so the documents agree with each other.

Traceable pricing

Quotation revision tracking means the agreed price and its history are available rather than argued about.

Accurate billing

Delivery-based invoicing and consolidated billing reduced the manual work at month end and the disputes that follow a wrong invoice.

Production visibility

Shortage and BOM management surfaced component gaps earlier, which is where they are cheap to solve.

Connected operations

Sales, manufacturing, logistics, finance and compliance work from one platform rather than meeting at the end of the month.

FAQ

Dhanalakshmi Industries: frequently asked questions

What did OdooBots implement for Dhanalakshmi Industries?

A customised Odoo ERP connecting sales, manufacturing, dispatch, invoicing and GST compliance, with automated E-Way Bill generation, custom business documents, quotation revision tracking, delivery-based invoicing and manufacturing shortage and BOM management.

Can Odoo generate E-Way Bills automatically?

Yes, through the Indian localisation and the GST integration, produced from the dispatch record. That matters most at the moment it happens: a vehicle loaded and waiting while somebody types details into a portal is a real cost in a manufacturing business.

What is delivery-based invoicing?

Billing for what was actually delivered rather than what was ordered, so a part dispatch invoices correctly and several dispatches can be consolidated onto one invoice. It removes most of the manual correction that otherwise happens at month end.

Why does quotation revision tracking matter?

Because a manufacturing quotation is often revised several times before it is accepted. Keeping every version means the agreed price and the date it was agreed are a record, which settles disputes without anyone searching an inbox.

Could this suit our factory?

If you quote, manufacture, dispatch and invoice, the shape is the same; what differs is your BOM complexity, document formats and GST position. The free diagnosis call is where those are established before anything is quoted.

Running something similar to Dhanalakshmi?

Tell us whether your E-Way Bills are generated or typed today, and how often a quotation gets revised. Those two answers shape the project, and the diagnosis call is free.
