Every document type required under Indian GST — in one place

Whether you're a GST-registered seller, a composition dealer, or sending a quote before the deal is confirmed — Growkit generates the right document automatically.

GST tax invoice

Legally binding. Carries CGST/SGST or IGST auto-determined from seller vs buyer state. Sequential numbering per GST rules.

Primary document
Proforma invoice

A quote with no tax liability. Converts cleanly into a tax invoice once the buyer confirms — without ever editing the original.

Pre-sale
Bill of supply

For composition-scheme sellers or exempt goods. No GST charged or shown — compliant with rules that prohibit tax collection.

Composition dealers
Receipt voucher

Acknowledges an advance payment mid-job. GST reverse-calculated on the advance — nets automatically against the final invoice.

Job cards
Credit note

Post-issue corrections and returns. Linked to the original invoice with a full audit trail.

Phase 2
Debit note

For upward revisions — when the amount owed increases after the original invoice was issued.

Phase 2

From a catalog order or from scratch — your choice

Both paths produce a GST-compliant invoice. The difference is where the line items come from.

From a catalog order

Items, quantities, prices, and all discounts pull in automatically from the order. The invoice locks them as a read-only snapshot — it never recalculates or re-derives pricing.

  • Buyer's order pre-fills everything
  • Discounts from checkout carry over exactly
  • GST calculated on locked net taxable value
  • One click to send the invoice

Independent invoice

Build from scratch — either with free-form line items or by pulling products from your inventory. Discounts entered manually at the time of billing.

  • Pull products from inventory or type free-form
  • Add product-level and total invoice discounts
  • Works for calls, services, or any custom deal
  • Proforma option available on both paths

GST calculated correctly — even when an invoice has mixed tax rates

Every invoice runs discounts through a strict sequence before GST is applied. This keeps tax correct when a single bill mixes 5%, 12%, and 18% GST lines.

1
Product-level discountFlat or percentage per line item
2
Quantity-tier discountFlat or percentage for bulk orders
3
Invoice-total discountFlat or percentage on the whole billAllocated proportionally across lines
4
GST appliedOn final net value per lineCorrect even with mixed rates

Discounts can be flat amounts or percentages. Invoice-total discounts are spread proportionally across lines so each GST rate group is taxed correctly.

Your buyer gets a secure link — no account needed to view or pay

Every invoice generates a shareable link protected by a one-time PIN sent via SMS or WhatsApp. Buyers open it, see the full breakdown, and pay directly.

  1. 1
    You send the invoice link

    One click from your Growkit dashboard — the link goes out via WhatsApp, SMS, or email with a one-time PIN automatically.

  2. 2
    Buyer unlocks with the PIN

    No account signup needed. The PIN arrives on their phone — they enter it, the invoice opens instantly.

  3. 3
    Buyer sees the full breakdown

    Seller details, buyer details, line items with HSN codes, GST split, amount summary, and balance due — all clearly laid out.

  4. 4
    Buyer pays directly

    The Pay now button links to UPI or bank transfer. Payment integration live soon — provision is already in place.

Invoicing plugs into the rest of Growkit automatically

You don't need to enter the same information twice. Orders, job cards, and inventory all talk to the invoice module.

Catalog orders

Every confirmed order can generate a GST invoice in one click — pricing locked from checkout, never recalculated.

Job cards

Advance payments on job cards generate receipt vouchers that automatically net against the final invoice balance.

Inventory

Invoicing from inventory-linked line items reserves and deducts stock on issue. Proformas never touch stock.

Proforma to tax invoice

Convert a proforma into a tax invoice without editing it — the original is always preserved in the audit trail.
