# ARUKZ ERP for engineering, fabrication and foundry

> How machine shops, fabricators, pump and valve makers, foundries and forging units use ARUKZ ERP: work centres, downtime, lots, job work and scrap.

ARUKZ ERP fits machine shops, fabricators, pump and valve makers, foundries and forging units: routings, work centres and work orders plan the job, downtime reasons show where machine hours went, lots and serials trace material and finished pieces, outside processes go on job work challans, and scrap is recorded against the work. Ferrous scrap sales, OSH Code registration and BIS-marked steel are rules you still track yourself.

## What you use

> [card] [Work centres and work orders](https://docs.erp.arukz.com/modules/manufacturing.md)
>
> BOMs with operations on work centres, manufacturing orders split into work orders, costing and scheduling.

> [card] [Downtime reasons](https://docs.erp.arukz.com/modules/manufacturing.md)
>
> Hours lost on a work centre, with the reason, so a missed target has an explanation.

> [card] [Lots and serials](https://docs.erp.arukz.com/modules/lots-and-expiry.md)
>
> Bar stock and castings received into lots; pumps, valves and assemblies by serial number.

> [card] [Job work challans](https://docs.erp.arukz.com/modules/job-work.md)
>
> Machining, heat treatment, plating or painting sent out on a challan, with the return due date.

> [card] [Scrap](https://docs.erp.arukz.com/modules/inventory.md)
>
> Scrap moved out of stock as its own operation, so it does not sit in stock unseen.

> [card] [Tools, dies and maintenance](https://docs.erp.arukz.com/modules/maintenance-and-assets.md)
>
> A tool and die life log, an asset register and preventive maintenance schedules.

## A job from order to invoice

**1. Quote and confirm**

A quotation becomes a sales order. See [Sales](https://docs.erp.arukz.com/modules/sales.md).

**2. Buy the material**

Plate, bar or castings are bought and received into lots. See [Purchases](https://docs.erp.arukz.com/modules/purchases.md).

**3. Make it**

A manufacturing order consumes the lots, its work orders run on work centres, and downtime is logged with a reason.

**4. Send out what you do not do in-house**

A job work challan takes parts to the job worker; the return closes it, with any loss recorded. See [Job work](https://docs.erp.arukz.com/modules/job-work.md).

**5. Inspect, deliver, invoice**

Inspection records rejections against the order and lot, the delivery goes out, and the GST invoice follows. See [Quality](https://docs.erp.arukz.com/modules/quality.md) and [GST invoicing](https://docs.erp.arukz.com/gst/invoicing.md).

## The rules you meet

| Rule | What it says |
| - | - |
| Job work | CGST Act s.143 and Rule 55: a challan for every outside process; inputs back within 1 year, capital goods within 3 |
| Scrap | Ferrous scrap (HSN 7204) is 18% GST, and TCS applies on its sale under the Income-tax Act, 2025 |
| OSH Code | Register within 60 days once you have 10 or more workers. A factory is 20 or more workers with power, or 40 or more without |
| BIS steel | Use only BIS-marked steel for products covered by the Steel Quality Control Orders |
