ERPNext Implementation in Kolkata
ERPNext Implementation in Kolkata
You buy in pieces, you produce in square feet and you sell in pairs. Two conversions sit between your cost and your price, and both of them move with the hide.

The Government of West Bengal states that the state holds about half of India’s leather goods exports, runs 538 of the country’s 2,020 tanneries and accounts for roughly 30 per cent of its footwear and leather goods units. Kolkata and its suburbs are the centre of that. Leather is the most awkward material an ERP will ever be asked to cost, because it arrives as an animal and leaves as a handbag, and nothing in between is measured the same way twice.
What an ERPNext implementation in Kolkata has to solve
The core problem is unit of measure. Raw hides are bought by the piece, or sometimes by weight. Finished leather is made, sold and consumed in square feet. Products are ordered and despatched in pairs or pieces. Between the purchase and the sale there are two conversions, neither of them fixed, and both of them varying with the individual hide. A system that stores one unit per item and hopes for the best will produce a cost sheet that nobody in the factory believes.
The second is grade. A hide is a natural surface with natural defects, and it gets graded at every stage: raw, wet blue, crust, finished. The grade is not a comment in a remarks field. It determines the realisation, it determines which orders that leather can serve, and two batches with the same square footage can differ in value by a wide margin. Grade has to be an attribute the system can cost and plan against.
The third is cutting yield, which is where the margin actually lives. You are cutting fixed shapes out of an irregular surface with holes in it. The percentage of purchased area that ends up in a saleable product is the single number that decides whether an order made money, and it varies by hide, by grade, by pattern and by cutter. If yield is not captured against the order, the costing is a standard rate pretending to be a fact.
Three units of measure, two conversions
Pieces in, square feet through the process, pairs or pieces out, with the conversion recorded per lot rather than assumed. Both conversions have to be visible in costing, because both of them move.
Grade as a costed attribute
Grading captured at raw, wet blue, crust and finished stage, carried on the batch, and used in both valuation and order allocation. Where a grade boundary sits is your commercial call, not ours; the system’s job is to apply it consistently.
Cutting yield against the order
Area issued against area consumed and area wasted, per order and per pattern. Yield is the margin, and a standard yield applied to every hide is a way of not knowing.
Wet blue and crust are stock
Intermediate states that can be sold, bought, held for months or sent out for processing. Treating them as work in progress inside a single production order hides both saleable inventory and real cost.
How we deliver in Kolkata
We start with units of measure and the item master, because everything else is downstream of it. Purchase unit, stock unit, conversion handling per lot, grade as an attribute, and the intermediate states held as their own stock items. This sounds like configuration housekeeping and it is the whole project: get it wrong and every report afterwards is quietly incorrect.
Then process and yield: the chemical stages with their recipes, batch tracking through soaking, tanning, dyeing and finishing, subcontracted processing where hides leave your premises and come back changed, and area issued against area consumed at cutting. Costing, export orders and documentation come last, once the floor is recording area and grade honestly.
Typical delivery phases for a Kolkata implementation
| Phase | What happens | Why it comes here |
|---|---|---|
| 1. Discovery | Map units of measure, grading conventions, the intermediate states you hold and where processing is subcontracted. | Unit and grade conventions differ house to house. Assuming ours would be a costly guess. |
| 2. Items and stock | Item master with purchase and stock units, per-lot conversion, grade attributes, wet blue and crust as stock items. | The whole costing model rests on this, so it is built and agreed first. |
| 3. Process and yield | Chemical stage recipes, batch tracking, subcontracted processing, area issued against area consumed at cutting. | Needs a trustworthy item and unit structure underneath before it means anything. |
| 4. Costing and export | Order costing on actual yield and grade, stock valuation, export orders and documentation. | Costing is only meaningful once the floor is recording real area and real grade. |
We avoid go-live during a peak export shipping window. Cutting and finishing staff learning a new area-capture step in the week a container is booked is a risk with no upside, and the peak is exactly when the old system’s gaps are least visible.
Are you ready? A short readiness check
- Do you know your average cutting yield by grade, or only an overall standard percentage?
- Is grade recorded against the batch in a way you can report on, or written on the leather and remembered?
- Can you value your wet blue and crust stock separately from finished leather?
- When hides go out for processing and come back, is the weight or area difference reconciled?
- Does your costing use the area actually consumed on an order, or a standard consumption?
Four or five clear answers means you mostly need a system that keeps a discipline you already have. Two or fewer means the first phase is agreeing units and grading across the floor, and doing that properly is the difference between a costing you trust and one you check by hand.
Frequently asked questions
Can ERPNext handle buying in pieces and stocking in square feet?
Yes. Items carry a stock unit and alternate purchase units with conversion factors, and the conversion can be recorded per receipt rather than fixed, which is what leather needs because the area you actually get varies by hide.
How is grade handled?
As an item attribute or a batch attribute depending on how you trade, so grade flows into valuation, availability and order allocation. Where the grade boundaries sit is a commercial decision for you; we implement the definitions you set.
Can it track cutting yield per order?
Yes, by recording area issued against area consumed and scrap at the cutting operation. It is a process change on the floor more than a configuration exercise, and it is the change that makes order costing real.
What about hides sent out to another tannery for processing?
Subcontracting holds material you own at a third party, with what went out and what came back reconciled including the area or weight difference. That reconciliation is usually where unrecorded loss has been sitting.
How long does an ERPNext implementation take for a leather business?
Ten to sixteen weeks for a single unit with settled unit and grading conventions. Longer where tanning and goods manufacturing are both in scope, or where conventions differ between departments, which is common and is time well spent.
Key takeaways for Kolkata businesses
- Leather crosses three units of measure. Record both conversions per lot or your cost sheet is a guess with decimals.
- Grade decides realisation, so it belongs in valuation and allocation, not in a remarks field.
- Cutting yield is the margin. A standard yield applied to every hide is a way of not knowing which orders made money.
- Wet blue and crust are saleable stock in their own right. Buried inside work in progress, they hide both inventory and cost.
Planning ERPNext for a Kolkata leather or manufacturing business?
Start your ERPNext implementation with a team that will settle units, grade and yield before it builds a cost report. KlyONIX Tech™ is a Frappe Certified Partner with offices in Pollachi and Chennai, working with manufacturers across eastern India.
Export share, tannery count and unit share from the Government of West Bengal’s official Leather Industry page on the Egiye Bangla state portal, maintained by the Information and Cultural Affairs Department. The page states 538 tanneries out of 2,020 in India (26.6 per cent), about a 50 per cent share of India’s leather goods exports, and about 30 per cent of its footwear and leather goods units. Only these structural figures are used here: the same page carries export values for 2015-16 and a turnover projection to 2020, both of which are dated, and neither is reproduced. These are state-level figures, and Kolkata with its suburbs is the centre of the state’s cluster rather than the whole of it. Source checked July 2026.
