Manufacturing
Inventory software for manufacturing units that buy, make and sell
Castings and copper wire in, stators and pumps out, each counted in its own unit and godown, valued at weighted average cost and changed only by a document you can open.
In short
SimpleERP is inventory software for small manufacturing units in India. A pump maker keeps castings, copper winding wire, bearings and finished pumps by godown at weighted average cost, and stock moves only when a bill, work order, transfer or invoice posts.

A stock day at Kaveri Flow Pumps
The stores at Kaveri Flow Pumps hold three kinds of stock. Bought-out parts arrive from suppliers: CI castings for pump bodies from a foundry in Ganapathy, copper winding wire in 25 kg spools, bearings by the box and capacitors by the hundred. Made parts come off the shop floor, such as wound stators. Finished pumps wait in a separate godown near the loading bay.
Copper is the item that keeps the owner awake. A spool bought at ₹890 a kilo in June and another at ₹935 in August sit on the same rack, and the stator cost depends on which one was used. The storekeeper also needs to know whether there are enough 6205 bearings for next week's run of 60 monoblocks before the bearing dealer's van comes on Thursday.
SimpleERP keeps one product per item with its own unit, and stock changes only when a document posts: a purchase bill brings castings and wire in, a work order draws them down, a transfer moves finished pumps to dispatch and an invoice takes them out. The June and August spools blend into one weighted average rate per kilo.
Which units and godowns does a pump maker need?
Each item is a product with one unit, and each place stock sits is a warehouse. Set a reorder level on the items that stop the line when they run short.
- Kilograms for wire, numbers for castings, and the work order turns both into finished pumps
- Reorder level per product; the low stock list shows what has dropped below it and you decide what to buy
- Weighted average cost per product, worked out again on every purchase bill
| Product family | Unit | Godown | Reorder pattern |
|---|---|---|---|
| CI castings: pump bodies, motor yokes | Nos | Raw stores | Two weeks of assembly; the foundry takes about ten days |
| Copper winding wire | kg | Raw stores | Below 150 kg; bought in 25 kg spools |
| Bearings, seals, capacitors | Nos | Raw stores | A level per size, checked before each run |
| Wound stators | Nos | Shop floor | Made in-house on work orders, never purchased |
| Monoblock and submersible pumps | Nos | Finished goods | Built ahead of the dealer season, to order after it |
Is there enough copper and bearings for a run of 60 pumps?
Planning a work order works out the materials from the bill of materials, scrap included, and checks each one against the raw stores. A shortfall in winding wire or 6205 bearings shows on the plan with a button to raise a purchase order for it.
- Nothing moves until completion, so a planned run never distorts the count on the rack
- Purchase order from the shortfall, filled with the quantity still needed
- Part deliveries from the bearing dealer tracked line by line on the order

Why does the stock register disagree with the rack?
Because something moved without a document. In SimpleERP every change is a movement with a date, a type and a link to the bill, work order, transfer, invoice or count behind it, so the answer to why it says 112 castings is one click away.
- Count-mode adjustments after the month-end physical count, each with a reason such as foundry rejection
- Transfers between raw stores, shop floor and finished goods, each a posted document
- Stock valuation with quantity per warehouse at one average cost per product, with CSV export for the auditor
What happens to castings rejected at machining?
A casting that cracks on the lathe goes back to the foundry on a debit note against the original bill, which takes it out of stock and cuts what you owe. A pump a dealer returns unopened comes back into finished goods on a credit note against his invoice.
- Debit note linked to the foundry bill, with input GST reversed in the same step
- Credit note linked to the dealer invoice, putting the pump back at its cost

Honest limits
What SimpleERP does not do yet
- No batch, lot, serial or expiry tracking, and no barcode scanning
- Weighted average cost only; there is no FIFO
- No automatic reorder suggestions: the reorder level shows what is low, you decide what to buy
- Pump serial numbers for warranty are not stored on stock; type the serial into the invoice line description
- Stock lying with a dealer on consignment is not tracked as yours; invoice it when it leaves your godown

FAQ
Questions, answered
Can I keep copper wire in kilograms and sell pumps in numbers?
Yes. Every product has its own unit. Winding wire is bought and stocked in kg, castings and bearings in Nos, and the work order turns those into finished pumps in Nos at the cost of what was actually drawn from the raw stores.
Will a jump in copper prices show in my pump cost?
Yes, in the next run. A new spool bill raises the weighted average cost of the wire, the next stator work order consumes it at that average, and the pumps built from those stators enter stock at the higher cost. Older pumps keep the cost they were made at.
Can the storekeeper count stock on a phone?
Yes. SimpleERP runs in a phone browser, and a stock adjustment in count mode lets the storekeeper type what is on the rack. The difference is posted with the reason he gives, and the movement shows his name and the time.
Does SimpleERP track pump serial numbers?
No. Stock is tracked by product and warehouse, without serial or batch numbers. Many pump makers type the motor serial into the invoice line description, so it prints on the dealer's copy and can be found later by searching invoices.
