Salem's economy runs on process industries that turn raw material into graded output: billets into TMT bars, tapioca into sago and starch, yarn into sarees, mangoes into pulp. In each of these, money is made or lost on yield, and yield is exactly what a Tally-plus-spreadsheet set-up cannot show you unit by unit and batch by batch.
ERPNext records the whole chain — weighbridge receipt, furnace or kiln batch, finished stock, despatch and GST invoice — in one open-source system with no licence fee. Thirvusoft, based in Coimbatore, has implemented it for more than 50 businesses across Tamil Nadu and India, and Salem is close enough for regular on-site work.
This page covers what ERPNext does for the industries around Salem, Attur, Mettur, Edappadi and Sankagiri, how costing across several units is handled, and what an implementation with us looks like.
Where ERPNext fits in Salem's industrial mix
Salem businesses rarely run a single process under one roof. A steel group may own an induction furnace, a rolling mill and a trading depot. A sago manufacturer may crush roots in Attur and dry and grade elsewhere. Saree businesses in Elampillai put weaving out to household powerlooms and finish in-house. These are multi-unit, multi-stage operations where the owner's real question is simple: what did this batch cost, and what margin did it leave?
- Steel: induction furnaces, re-rolling mills, TMT and structural sections, scrap trading
- Sago and starch: tapioca procurement, crushing, settling, roasting and grading
- Textiles: powerloom and handloom sarees, yarn dyeing, finishing and wholesale
- Food processing: mango pulp and seasonal fruit, drum and can packing
- Silver ornaments: anklets and jewellery priced by weight, karigar job work
- Transport: lorry fleets with trip-wise revenue and cost
Steel and rolling mills: costing per heat
A re-rolling mill buys scrap or billets by weight, burns power and furnace oil, loses a percentage as burning loss and mill scale, and sells bars by size and grade. ERPNext's Manufacturing module treats each heat or shift as a work order: actual material consumed, power and fuel booked as additional costs, and scrap recorded as a by-product with its own value. The output is a real cost per tonne of finished bars rather than an averaged guess.
Sizes such as 8 mm, 10 mm, 12 mm and 16 mm are set up as variants of one item template, so stock reports show tonnage by size at a glance. Weight-based units with piece and bundle conversions handle mixed sales, and the e-way bill for every lorry load is generated from the delivery note through the India Compliance app.
Sago and starch: seasonal buying, yield and by-products
Tapioca arrives in season, is bought by lorry load, and its value depends on starch content. ERPNext handles this with a purchase receipt per load, inspection fields for starch percentage and moisture, and supplier-wise rates. Crushing yields wet starch and thippi; the manufacturing entry records sago or starch as the main output and thippi as a saleable by-product, so yield per tonne of roots is visible for every lot.
Batch numbers carry grade, moisture and production date through to the sales invoice, godown stock is tracked per unit, and seasonal advances paid to farmers are settled against deliveries in the Accounts module.
Sarees, silver and transport on one system
Elampillai and Salem saree makers send yarn to weavers and dyers and receive finished pieces back. ERPNext's subcontracting flow issues yarn on a job-work challan, shows what each weaver holds, and receives sarees with weaver-wise conversion charges, so piece-rate payments and yarn shortfall are both accounted for. Design, colour and length become item attributes for the wholesale catalogue.
Silver ornament makers price by weight and purity plus making charges; pricing rules and a daily rate update handle gram-wise billing. Transport operators book trip-wise revenue, diesel, driver bata and tolls against each lorry as a cost centre, giving a profit figure per vehicle and per route.
Costing across units and GST across locations
A group with a furnace in one town, a mill in another and a depot in a third can be set up as one company with several branches and warehouses, or as separate companies with consolidated reports, depending on how the GST registrations are held. Each unit is a cost centre, so power bills, wages and depreciation land in the right place and a unit-wise profit and loss statement is a standard report.
Transfers between units move on delivery challans with e-way bills where required; where units hold separate GSTINs, the transfer is invoiced with the correct tax. GSTR-1 and GSTR-3B data is compiled per GSTIN by the India Compliance app.
| Set-up | When it suits | What you get |
|---|---|---|
| One company, many branches | All units under one GSTIN or one legal entity | Unit-wise P&L through cost centres; stock transfers without invoicing |
| Separate companies | Different GSTINs, partners or legal entities per unit | Inter-company invoices and consolidated financial statements |
| Mixed | A manufacturing group plus a trading firm | Trading firm buys from the mill at a transfer price; group-level margin reports |
What an implementation in Salem looks like
We begin with a discovery visit to your units to map processes and the reports you actually rely on. Configuration and customisation follow, then data migration from Tally, Excel or an older ERP, role-wise training in Tamil or English at your site, and go-live with hyper-care before moving to an annual support contract. Trading and service firms are typically live in four to eight weeks; manufacturers with BOMs, job cards and costing take eight to fourteen.
Salem is around three hours by road from our Peelamedu office, so on-site days are easy to schedule during configuration and go-live, with remote support in between. ERPNext has no licence fee; you pay for implementation, customisation, hosting and support, and we give a fixed-price quote after discovery.
Integrations Salem process industries ask for
Weighbridge readings, biometric attendance and WhatsApp are the three most common requests. Weighbridge weights are captured on purchase receipts and delivery notes, by entry or by integration where the weighbridge software allows it. Biometric devices such as eSSL and ZKTeco feed attendance into Frappe HR for shift-based payroll with PF and ESI. WhatsApp delivers invoices, e-way bills and payment reminders to customers and transporters, and IndiaMART enquiries flow into the CRM module for steel and sago traders who sell nationally.
