Does Stock Register calculate CGST, SGST, and IGST automatically?

Yes, Stock Register automatically determines whether a transaction is intra-state or inter-state based on your business GSTIN and the buyer's GSTIN and state code. Intra-state sales get CGST + SGST, inter-state sales get IGST — applied automatically. All GST slabs are supported — 5%, 12%, 18%, and 28% — including cess calculation for applicable items. You do not manually choose the tax type, so the most common GST invoicing error is eliminated.

What document types can I create?

Stock Register supports nine document types: Sales Invoice (Tax Invoice), Purchase Invoice, Sales Return (Credit Note), Purchase Return (Debit Note), Sales Order, Purchase Order, Quotation, Payment In, and Payment Out. Every document type follows GST formatting rules with all mandatory fields. Sales returns and purchase returns are linked to the original invoice for audit trail and correct GST reversal.

Do I need to enter all party details to create an invoice?

No, you only need the party name to create an invoice. Phone number, GSTIN, PAN number, address, bank details, and any custom fields are all optional and can be added later. This is designed for speed — you can bill a walk-in customer in seconds. When you do add a party's GSTIN, the system auto-detects their state, and every future invoice to that party will apply the correct CGST/SGST or IGST automatically.

Are HSN codes included on invoices?

Yes, Stock Register includes a complete HSN code database. Map the correct HSN code to each product in your catalogue once — after that, every invoice automatically includes the correct HSN code for that item. This one-time setup ensures all your invoices are GST-compliant. HSN codes are mandatory on all GST invoices and required for your buyer to claim input tax credit.

Does creating a sale invoice automatically update stock?

Yes, every sale invoice automatically reduces stock for the sold items. Every purchase bill automatically increases stock. Sales returns add stock back, purchase returns reduce it. There is no separate stock entry needed — your inventory is always in sync with your billing. This also means your stock reports, item ledger, and inventory aging are always up to date.

Can I share invoices via WhatsApp?

Yes, after creating an invoice you can share the invoice URL directly via WhatsApp to the buyer in one tap. The buyer receives a link to view and download the professional PDF invoice. You can also download the PDF and share it manually via email or any other app. The invoice includes your logo, bank details, QR code, and digital signature — just like a printed copy.

What invoice print options are available?

Stock Register offers 5 A4 themes, 2 A5 compact themes, and thermal printing support for 2-inch, 3-inch, and 4-inch printers. Switch between themes anytime. Print multiple copies with different labels — Original copy for the buyer, Transport copy for the transporter, Supplier copy for your records, and Delivery copy for the receiving warehouse. You can also download as PDF for digital sharing.

Can I customise the invoice with extra fields, discounts, and custom columns?

Yes. You can add item-wise discounts, discount before tax, and extra charges like packaging or freight. The item table supports custom columns — add Color, Size, Brand, or any field you need. You can also add invoice-level extra fields like Vehicle Number, Transporter Name, Shipping Company, and LR Number. For your business header, add custom fields like Drug License, FSSAI Number, or Website. Every invoice can include a Remark, Terms & Conditions, bank details, and an uploaded signature image.

Common problems this solves

Wrong Tax Calculation — CGST/SGST vs IGST Confusion

The most common GST invoicing mistake in India is applying the wrong tax type. Intra-state sales need CGST + SGST, inter-state sales need IGST — but many businesses get this wrong, especially when a party has branches in multiple states. A wrong tax split means the buyer's input tax credit gets rejected, and your business gets a GST notice. The penalty for incorrect invoices can be up to ₹25,000 per return period.

Stock Register auto-detects whether the transaction is intra-state or inter-state from the party's GSTIN and state code, and applies the correct CGST + SGST or IGST split. You cannot make this mistake because the system does not let you choose the wrong tax type.

Missing Mandatory Fields — Invoice Rejected by Buyer

A valid GST tax invoice requires 16+ mandatory fields — supplier GSTIN, buyer GSTIN, HSN/SAC codes, place of supply, sequential invoice number, tax breakup, and more. Miss even one field and the buyer cannot claim input tax credit on your invoice. Large buyers and government departments routinely reject invoices with missing HSN codes or incorrect GSTIN formatting.

Stock Register pre-maps HSN codes to every item in your catalogue. All mandatory GST fields — GSTIN, place of supply, HSN codes, tax breakup, sequential invoice number — are auto-filled on every invoice. You cannot generate an invoice with missing fields.

Hours Wasted Compiling Data for GSTR Filing

At the end of every month, businesses manually compile invoice data from paper registers or Excel sheets to file GSTR-1 and GSTR-3B. This double-entry wastes 6-10 hours per month for a typical wholesale business, and the manual compilation introduces errors that cause mismatches between your filed returns and the buyer's GSTR-2B — triggering notices from the GST department.

Stock Register exports GSTR-1 and GSTR-2 reports in one click — with all invoice data, HSN summaries, and tax breakups ready to upload to the GST portal or share with your CA. Zero manual compilation.
