GST billing software for rice mills
Bill every lorry of raw rice, boiled rice, broken rice, bran and husk on a GST invoice that knows the HSN, the packing rate and the buyer's state.
In short
SimpleERP is GST billing software for rice mills in India. Each invoice line carries HSN 1006 or the bran and husk code, takes nil or 5% from the product, and splits CGST and SGST or IGST by place of supply.

A GST billing day at Ponni Valley Rice Mill
At Ponni Valley Rice Mill in Thanjavur the billing desk opens when the first lorry is loaded. Today it is 220 bags of boiled rice in 25 kg labelled bags for a wholesaler in Kumbakonam, then 90 quintals of loose raw rice for a hotel supplier in Tiruchirappalli, then a load of husk for a brick kiln near Pudukkottai.
Each buyer needs something different on paper. The labelled bags carry 5% GST, the loose rice for the hotel supplier has been nil-rated, and the cattle feed dealer from Bengaluru wants bran billed across the state border, which turns the tax into IGST.
In SimpleERP the clerk picks the buyer, types the product and the quantity, and the line fills its HSN, unit and rate. Saving the invoice takes the rice out of the godown at average cost, adds the amount to the trader's balance and writes the GST in one step.
How does one invoice handle rice at two GST rates?
The rate sits on the product, not on the invoice. Make boiled rice in labelled 25 kg bags one product at 5% and loose raw rice another at nil, and a trader who takes both gets one invoice with each line taxed correctly and an HSN summary at the foot.
- Separate products for packed and loose rice, so the rate never depends on the clerk's memory.
- HSN on every line prints on the A4 copy, ready for the GSTR-1 HSN table.
- Nil-rated lines show a zero tax amount and stay apart from taxable sales in the sales register.
- Broken rice is its own product with its own rate per quintal.
| Product | HSN | Usual rate | Unit you bill in |
|---|---|---|---|
| Raw rice, loose and unbranded | 1006 | Nil | kg or quintal |
| Boiled rice, 25 kg labelled bags | 1006 | 5% | bags |
| Broken rice, loose | 1006 | Nil | quintal |
| Rice bran for cattle feed | 2302 | Nil | kg |
| Husk sold as fuel | 1213 | Nil | tonne |
What happens when a lorry crosses into Karnataka?
The place of supply decides the tax. When the bran dealer's shipping address is in Bengaluru, SimpleERP switches every taxable line to IGST at the same rate while you type, and again when you post, so an inter-state load never goes out with CGST and SGST.
- GSTIN validation fills the buyer's state from the number.
- A shipping address per delivery point sets the place of supply for that load.
- An intra-state rate on an inter-state load is refused, naming the line to fix.
- The lorry number goes in the invoice notes for the driver.

Can I bill in bags when the godown counts in kilos?
Each product has one unit, so choose the unit you sell in. A product kept in bags is billed and stocked in bags; a product kept in kilos takes three decimals, so 4,862.500 kg from the slip goes on the line exactly as weighed.
- Add a bag or quintal unit once in settings and pick it on the product.
- Rate per unit fills from the product and can be changed on the line before saving.
- Credit notes for a short-weight complaint return the difference and, if needed, the stock.
- Amount in words in lakh and crore prints on every invoice.
Who pays on time, and who is stretching to ninety days?
Wholesalers in the delta take rice on credit through the season. Every invoice adds to the trader's ledger, every UPI or bank receipt settles the oldest invoices first, and receivables ageing shows who is past 30, 60 or 90 days before the next lorry is loaded.
- Credit limit warning when a new invoice would push a trader over the limit you set.
- UPI QR on the invoice print so a small buyer can pay at the mill gate.
- Customer statements list every load and payment for the season.
- Sales register to check before your CA files GSTR-1.

Where GST billing connects
An invoice moves rice out of the godown, books the sale and the GST, and adds to the trader's balance in the same step.

FAQ
Questions, answered
Is rice nil-rated or 5% on my invoice?
It depends on how you sell it. Rice under HSN 1006 sold loose and unbranded has been nil-rated, while rice in pre-packaged, labelled bags of up to 25 kg has carried 5%. Keep the two as separate products in SimpleERP so each line takes the right rate. Rates change, so confirm the rate for your goods with your CA or the GST portal before you rely on it.
Can I bill husk to a brick kiln and bran to a feed dealer from the same book?
Yes. Husk and bran are products like rice, each with its own HSN, rate and unit. One numbering series covers every invoice, such as INV-2026-27-0412, so the kiln's husk load and the feed dealer's bran sit in the same sales register with their own HSN lines.
Does SimpleERP create the e-way bill for a rice lorry?
No. E-way bills and e-invoice IRNs are not generated through the government portals. Raise the invoice in SimpleERP, then create the e-way bill on the portal with the invoice number and value, and keep its number with the lorry's dispatch papers.
My munshi bills at the mill and I check from home. Is that possible?
Yes. SimpleERP runs in the browser on a phone or laptop, so the munshi posts invoices at the mill while you read the sales register and ageing from home. Give the munshi the Sales role so payroll and the ledger stay out of view.
