Invoice24 fills all of this in automatically from your business profile and the client's state. https://invoice24.in/blog/how-to-write-a-quotation/ https://invoice24.in/blog/how-to-write-a-quotation/ Tue, 06 Oct 2026 06:00:00 GMT Quotations A good quotation has a clear subject, your business details and the client's, a dated quotation number, an itemised scope with quantities and prices, taxes shown separately, the total, payment terms and schedule, delivery timeline, validity period and numbered terms. Send it within 24 hours, offer optional add-ons rather than one fixed price, and make it easy to accept – for example with an approval link on WhatsApp. https://invoice24.in/blog/quotation-vs-proforma-vs-tax-invoice/ https://invoice24.in/blog/quotation-vs-proforma-vs-tax-invoice/ Sat, 03 Oct 2026 06:00:00 GMT Invoicing A quotation is an offer sent before the deal. A proforma invoice confirms the order and is used to collect an advance – it is not a tax document and no GST liability arises from it. A tax invoice is issued when the goods or services are supplied; it carries GST and lets a registered buyer claim input tax credit. A credit note reduces an invoice already issued. https://invoice24.in/blog/cgst-sgst-igst-explained/ https://invoice24.in/blog/cgst-sgst-igst-explained/ Wed, 30 Sep 2026 06:00:00 GMT GST & tax Charge CGST + SGST (half the rate each) when the supplier's state and the place of supply are the same; charge IGST (the full rate) when they are in different states, for imports, exports and supplies to SEZs. In union territories without a legislature, UTGST replaces SGST. The place of supply – not the buyer's billing address alone – decides which applies. https://invoice24.in/blog/export-invoice-under-lut/ https://invoice24.in/blog/export-invoice-under-lut/ Sat, 26 Sep 2026 06:00:00 GMT GST & tax To export without paying IGST, file a Letter of Undertaking (form GST RFD-11) on the GST portal for the financial year, then issue export invoices marked “Supply meant for export under Letter of Undertaking without payment of integrated tax”, showing IGST as 0%, the foreign buyer's name and address, the currency and – for goods – the port and shipping bill details. https://invoice24.in/blog/credit-note-under-gst/ https://invoice24.in/blog/credit-note-under-gst/ Tue, 22 Sep 2026 06:00:00 GMT Invoicing Issue a GST credit note when the value or tax on an invoice turns out too high – goods returned, a post-sale discount, a price correction or deficient services. It must reference the original invoice, show the reduced taxable value and tax, and be issued by 30 November after the end of the financial year (or the annual return date, if earlier). https://invoice24.in/blog/hsn-sac-code-on-invoice/ https://invoice24.in/blog/hsn-sac-code-on-invoice/ Fri, 18 Sep 2026 06:00:00 GMT GST & tax HSN codes classify goods and SAC codes classify services. If your aggregate turnover in the previous year was up to ₹5 crore, show at least a 4-digit HSN on B2B invoices (optional on B2C); above ₹5 crore, show 6 digits on all invoices. SAC codes for services are 6 digits and start with 99. https://invoice24.in/blog/solar-quotation-format/ https://invoice24.in/blog/solar-quotation-format/ Mon, 14 Sep 2026 06:00:00 GMT Quotations A rooftop solar quotation should state the system size (kW) and type (on-grid, off-grid or hybrid), panel and inverter make and wattage, structure, cabling and protection, installation and DISCOM net-metering work, warranty periods, the price split into supply and installation with GST, subsidy assistance, a payment schedule (for example 25% advance, 70% before dispatch, 5% on commissioning), validity and terms. https://invoice24.in/blog/payment-reminder-messages/ https://invoice24.in/blog/payment-reminder-messages/ Thu, 10 Sep 2026 06:00:00 GMT Business tips Send a friendly reminder 3 days before the due date, a short note on the due date, a firmer reminder 7 days after with the invoice attached, and a final notice at 15–30 days that states the next step. Always mention the invoice number, amount and a one-tap way to pay (UPI ID or bank details). https://invoice24.in/blog/company-letterhead-format/ https://invoice24.in/blog/company-letterhead-format/ Sun, 06 Sep 2026 06:00:00 GMT Business tips A company letterhead should show your logo, the registered business name, full address, phone, email and website, and – where they apply – GSTIN, CIN (for companies) and LLPIN (for LLPs). Keep the header small, use your brand colour once, leave generous margins and put registration details in a slim footer. https://invoice24.in/blog/invoice-numbering-rules/ https://invoice24.in/blog/invoice-numbering-rules/ Wed, 02 Sep 2026 06:00:00 GMT Invoicing Under GST, invoice numbers must be consecutive, no longer than 16 characters, use only letters, numbers, hyphens (-) and slashes (/), and be unique within a financial year. A common format is PREFIX/YEAR/NUMBER, such as INV/2026-27/001. You may run separate series for branches, proformas and credit notes.
