Title: ERP for GST in India URL: https://zudoworks.com/answers/erp-for-gst-in-india/ Description: GST ERP for a small manufacturer: GSTIN on every party, CGST, SGST or IGST on invoices, HSN codes, input tax credit, and what to confirm on the GST portal. Updated: 2026-11-03 # ERP for GST in India: what a small manufacturer needs An ERP for GST in India should hold a GSTIN for your business and every customer and vendor, carry an HSN or SAC code on each item, split tax on invoices into CGST and SGST for intra-state supplies or IGST for inter-state, record input tax credit on purchases, and export what your accountant needs for returns. Thresholds for e-invoicing and e-way bills change, so confirm them on the GST portal.

The ERP should decide this from the customer's state and your own, not leave it to the person typing the invoice. Each line needs an HSN code for goods or SAC code for services and the rate for that code. The 15-character GSTIN of both parties appears on the invoice. Rates and HSN digit requirements are set by the GST Council and change, so keep the rate table in the ERP editable and check the portal when a notification is issued. ## Purchases and input tax credit The money side of GST for a manufacturer is input tax credit: the GST paid on raw material, consumables and services is set off against the GST collected on sales. That only works if every vendor bill is recorded with the vendor's GSTIN, the tax split and the HSN, and if the vendor has filed on their side. The ERP should keep purchases in a double-entry ledger with tax accounts, so the accountant can reconcile your purchase register with what appears on the portal before filing. A purchase recorded without tax detail is a credit lost. ## What to confirm on the GST portal, not in software Some GST rules depend on your turnover and change by notification. Do not let an ERP vendor's summary stand in for the portal on these. - Whether e-invoicing applies to your turnover and from when - The value threshold and rules for e-way bills on goods movement - How many HSN digits your invoices must show - Current rates for your HSN codes after any Council change - Return forms and due dates for your registration type - ITC-04 frequency if you send goods for job work ## What a small manufacturer should check in an ERP Ask to see an intra-state and an inter-state invoice created for the same item and watch the tax split change by itself. Check that the rate table and HSN codes are editable by you. Record a vendor bill with GST and see the input tax posted to its own ledger account. Ask for the sales and purchase registers as exports your accountant can use. If the product promises filing, ask whether that is built in or a partner service, and confirm what happens when a rule changes. ## Where ZMOS fits ZMOS includes double-entry accounting with invoices, bills, journals, banking, GST/VAT tax rates and 22 financial reports in the same workspace as stock, work orders and purchasing, so a small manufacturer's GST data sits with its production data. Custom fields and validation rules can enforce GSTIN and HSN on every party and item. It is built for sheet-metal, machining and fabrication shops of 10 to 50 people in India. It is not a return-filing product: returns are filed on the GST portal, and shops whose main need is tax filing alone are better served by an accounting package such as Tally or Zoho Books.

The Goods and Services Tax Identification Number, a 15-character registration number for each registered business in India. Your ERP should store it on your own company record and on every customer and vendor so it prints on invoices and purchase records. When does an invoice show IGST instead of CGST and SGST? When the supply is inter-state, meaning the place of supply is in a different state from the supplier's registration. Intra-state supplies carry CGST and SGST in equal halves. The ERP should decide this from the state codes, not from manual entry. Does e-invoicing apply to my small manufacturing business? It depends on your aggregate turnover against a threshold set by notification, and that threshold has been lowered several times. Check the current threshold and your applicability on the GST portal, then confirm how your ERP or accountant will generate the IRN if it applies. Can an ERP file GST returns for me? Some products integrate with filing services; many export the registers for an accountant to file. Either way, filing happens through the GST portal or a licensed GSP. Ask the vendor exactly which returns are covered and what happens when a form or rule changes.
