ERP for Engineering and Casting Units in Rajkot: A Practical Guide

This guide is for owners, plant heads and accounts managers of casting, forging, machining, bearing and pump component units in Rajkot, Metoda GIDC, Shapar-Veraval, Aji GIDC and the Gondal Road belt who are running production on registers, spreadsheets and a billing package, and are deciding whether an ERP is worth the disruption. By the end you will know which problems an ERP actually solves in this kind of unit, what modules you need in which order, how long each stage takes, and what a fair price looks like.

A day inside a casting or forging unit in Rajkot

Every engineering unit in Saurashtra runs a version of the same loop. An order arrives, often on WhatsApp, for a quantity of a part with a drawing number. Someone converts that into a job card. Raw material is issued: pig iron, scrap and alloys for a foundry, round bar for a forge, castings or bar stock for a machine shop. Melting or heating happens in batches, each with a heat number. Castings are knocked out, fettled, sometimes heat treated, then machined either in-house or at a job worker two lanes away. Finished parts are inspected, packed, invoiced and dispatched, usually with an e-way bill.

The paperwork that follows this loop is where the pain sits: heat registers in one book, job work challans in another, rejection notes on loose sheets, and a billing package that knows only the final invoice. The owner knows the unit is profitable overall but cannot say which of the 40 parts it makes is losing money. That is the gap an ERP for the casting industry has to close.

The 6 problems an ERP fixes for engineering companies in Rajkot

1. Job cards and work in progress

Without a system, nobody can answer "where is order 218 right now" without walking the floor. An ERP creates a job card from the order, moves it through defined stages (moulding, pouring, fettling, machining, inspection, packing) and shows WIP by stage on one screen. Delays become visible on the day they happen, not when the customer calls.

2. Heat and batch traceability

Automotive and pump customers, and every export buyer, ask for traceability: which heat did this casting come from, what was the chemistry, who inspected it. An ERP records the heat number at pouring, links it to every casting from that heat, and attaches spectro results and test certificates. When a batch fails at a customer, you find the affected parts in minutes instead of recalling a whole month's production.

3. Job work under GST with ITC-04

Most Rajkot units send castings out for machining, plating or heat treatment, or receive material from a principal for job work. Under GST, goods sent for job work move on a delivery challan without tax, must come back within the time limit set in the rules (check the current limit on the GST portal), and the movement has to be reported on Form ITC-04. Done manually, challans go missing and the reconciliation before filing takes days. An ERP issues the challan, tracks what is out and with whom, matches returns and generates the ITC-04 data.

4. Yield and rejection

Casting yield, the ratio of good castings to metal poured, is the single biggest driver of profit in a foundry, and rejection at machining is the second. An ERP captures weight poured, good weight, returns and rejections by reason (blow holes, shrinkage, sand inclusion, dimensional) per heat and per pattern. After three months you know which patterns and which shifts lose money.

5. Dispatch and e-way bills

Dispatch is where accounts and stores meet, and where mistakes cost the most: wrong quantity on the invoice, missing e-way bill at a check post, a lorry waiting two hours for paperwork. An ERP generates the tax invoice and the e-way bill from the packing list, with the e-invoice IRN and QR where your turnover requires it. The threshold for e-invoicing has been lowered several times, so check the current figure on the official portal.

6. Real costing per part

Once material issue, heat data, yield, job work charges and machine time are all in one database, cost per part stops being an estimate. The ERP shows the actual material, conversion and outsourcing cost against the quoted price for every job. Many owners find that 10 to 20% of their parts are quoted below cost, and reprice them within a quarter.

Module map for a manufacturing ERP in Rajkot

The table below is the module structure we use for casting, forging and machining units. Not every unit needs every module on day one; the stage column shows the order that works in practice.

Module	What it covers	Who uses it	Stage
Masters	Items, patterns and drawings, customers, suppliers, job workers, machines, GST rates, HSN codes	Admin, accounts	1
Sales orders and job cards	Order entry from WhatsApp or PO, job card creation, stage tracking, WIP board	Sales, planning, floor supervisor	1
Stores and inventory	Raw material receipt, issue to production, consumables, stock by godown, reorder alerts	Storekeeper	1
Dispatch and billing	Packing list, tax invoice, e-invoice, e-way bill, delivery challan, credit and debit notes	Dispatch, accounts	1
Production and heat log	Heat entry, chemistry, pouring, yield, rejection by reason, shift output	Melting in-charge, QC	2
Job work	Outward and inward challans, pending job work register, job worker bills, ITC-04 data	Stores, accounts	2
Quality	Inspection plans, test certificates, customer complaints, rejection analysis	QC	2
Purchase	Indents, purchase orders, GRN with quality check, supplier rating	Purchase	2
Costing	Actual cost per job and per part, quoted versus actual, margin reports	Owner, accounts	3
Maintenance	Machine breakdown log, preventive schedule, spares	Maintenance	3
HR and payroll	Attendance from biometric, shift and overtime, contractor labour, PF and ESI data	HR, accounts	3
Accounts integration	Export of vouchers to the accounting package your CA uses, GSTR-1 and GSTR-3B data	Accounts, CA	1 to 3

Staged rollout: how long a manufacturing ERP takes

Trying to switch a working factory to a 12 module system in one go fails more often than it succeeds. The approach below has worked repeatedly for engineering companies in Rajkot.

1. Stage one, weeks 1 to 8: masters, orders, stores, dispatch. Clean the item and party masters (this alone takes two weeks in most units), load opening stock, and go live on job cards and invoicing. The billing package runs in parallel for one month. Success measure: every invoice for a full month generated from the ERP.
2. Stage two, weeks 9 to 20: production, job work, quality, purchase. Heat entry starts at the furnace on a tablet or a shared PC. Job work challans move to the system. By the end of this stage, ITC-04 data comes from the ERP and yield reports run by pattern.
3. Stage three, weeks 21 to 36: costing, maintenance, HR, dashboards. With six months of clean data, costing becomes meaningful. Owners get a daily WhatsApp summary: orders received, dispatched value, rejection percentage, cash collected.

Total: 4 to 9 months from kick-off to a complete system, with usable results from week eight. Each stage has its own sign-off and its own payment, which protects both sides.

How much does manufacturing ERP cost in Rajkot

Prices below are project prices for a custom built ERP that you own, hosted either on a server in your unit or on an Indian cloud region, for a unit with 20 to 100 staff and 5 to 15 concurrent users.

Scope	Price band (excl. GST)	Timeline
Stage one: masters, orders, stores, dispatch with e-invoice and e-way bill	₹1.5 lakh to ₹3 lakh	6 to 8 weeks
Stage two: production, heat log, job work with ITC-04, quality, purchase	₹1.5 lakh to ₹3 lakh	10 to 12 weeks
Stage three: costing, maintenance, HR and payroll, owner dashboards	₹1 lakh to ₹2 lakh	10 to 16 weeks
Hardware: server or cloud, 2 to 4 shop floor PCs or tablets, barcode printer	₹60,000 to ₹2 lakh	One time
Annual maintenance and support from year two	12 to 18% of build cost per year	Yearly

A complete three stage system therefore lands between ₹4 lakh and ₹8 lakh over the first year, and many units stop after stage two at ₹3 lakh to ₹6 lakh. Packaged ERP products with per-user subscriptions can look cheaper in year one but usually cost more by year three for a 10 user unit, and customising them for heat traceability or job work is often not possible.

What we have seen on casting and forging ERP projects

JK Tech Hub has built and supported ERP systems for engineering units across Metoda, Shapar-Veraval, Aji GIDC and Gondal Road since 2018, and a few lessons hold every time.

Masters decide everything. A casting unit in Metoda GIDC had 1,400 item codes in its billing package for about 300 real parts, because every operator had created a new code rather than search. Cleaning that list took the owner's son three weeks. It was the most valuable three weeks of the project, and the ERP would have failed without it.

Start heat entry at the furnace, not in the office. A forging unit near Shapar first tried entering heat data the next morning from a register. Numbers were wrong or missing a third of the time. A ₹15,000 rugged tablet at the furnace with a three field screen fixed it in a week.

Job work was the surprise win. A machining unit on Gondal Road with parts spread across six job workers discovered ₹9 lakh of material sitting outside for more than six months once the pending job work register was live. Some of it had been written off in their heads; most came back.

Costing reports change pricing. Every owner who reaches stage three has repriced parts within a quarter. One pump component unit found three of its highest volume parts were being made at a loss after job work charges and rejection were counted.

Finally, the person who matters most is not the developer or the owner but the supervisor who enters data on the floor. Where that person is trained personally and given a say in screen design, adoption is fast. Where the system is imposed from the office, entries stop within two months.

How to decide

If you can answer three questions from your current records within ten minutes, you may not need an ERP yet: where is each open order, what is your yield by pattern for last month, and what did part number X actually cost to make last quarter. If any of those takes hours, or is a guess, the six problems above are costing you more than stage one of an ERP.

Choose a firm that has built job work with ITC-04 and heat traceability before, and can show it live. Insist on a staged plan with a sign-off and a payment per stage, and on owning the source code and the database. Then clean your masters before the developer writes a line of code.
