Invoices

Two tax invoices per paid Order, their immutable numbering, and the credit notes a refund issues

A confirmed paid Order produces two tax invoices, not one: your Organization invoices the buyer for the ticket, and Ulsav invoices the Organization for the platform fee. Each is a legal document with its own seller, tax identifier, place of supply, and number.

That split is what makes the paperwork correct. Your accountant sees your revenue and your GST, and Ulsav's fee is a separate supply from a separate seller.

  • Per paid Order

Each invoice carries its own taxable value, its own tax components, and its own place of supply. Neither is presented as part of the other's supply.

For the buyer the two invoices add up to exactly what they paid. For you, only the organizer invoice is your revenue.

Numbering

Numbers are sequential per seller and per financial year, and they never change once issued:

DocumentShapeExample
Organizer tax invoiceINV/year/numberINV/2026-27/000042
Ulsav tax invoiceULSAV/year/numberULSAV/2026-27/000118
Organizer credit noteCRN/year/numberCRN/2026-27/000007
Ulsav credit noteULSAV/CRN/year/numberULSAV/CRN/2026-27/000011

The financial year runs April to March, so a sale in late March and a sale two weeks later in April fall into different series. Numbers come from a locked counter, so two simultaneous confirmations cannot take the same number.

The split, with real numbers

Order ORD-000123 totals ₹3,894.12: ₹3,150.00 of admission after the coupon, ₹567.00 of GST on it, ₹150.10 of platform fee, and ₹27.02 of GST on that fee.

The organizer invoice bills the admission and its tax; the Ulsav invoice bills the fee and its tax. Together they equal what the buyer paid.

The organizer invoice lists one line per Pass, with the quantity in chargeable units, the unit price, the effective tax rate, and the tax on that line. The Ulsav invoice has a single line for the platform fee.

Credit notes come from the refund

When a refund succeeds, each seller that issued an invoice issues a credit note against it. A credit note is never an edit of the invoice: it is a new document that references its parent.

The tax on a credit note is scaled from the parent invoice's own components, so a refund of one third of an invoice returns one third of each tax component. Amounts are whole paise with the rounding remainder placed on the last component, so a credit note never invents or loses a paise.

The organizer part is the refund minus the fee that came back; the rest is Ulsav's credit note for its share of the fee and its tax.

The organizer credit note splits further: ₹1,798.64 of admission and ₹323.75 of tax. That is the same split the refund made, which is why the two records always agree.

An automatic refund of a late or duplicate capture issues no credit note at all, because no invoice was ever issued for it.

The receipt is not an invoice

A receipt is the buyer's breakdown of what they paid. It quotes the Order number and points at the invoices; it never makes up an invoice number of its own.

That distinction matters when a buyer asks for a document. The receipt answers "what did I pay for"; the tax invoice answers "who charged me and what tax applied". Only the invoice is a tax document.

When invoices are issued

Issuance happens after the confirmation transaction commits, so a slow invoice can never hold up a sale. It is idempotent per seller: a duplicate provider callback finds the existing invoices and issues no second set.

Two cases produce nothing at all:

  • a free Order, whose grand total is zero
  • a paid Order with a zero platform fee, which gets the organizer invoice only

What can go wrong

Invoices are the one part of the flow that is not retried. If issuance fails after a sale confirms, the Order stays confirmed and correct, but the documents are missing, and nothing reissues them automatically today.

What happenedResult
The invoice step fails after confirmationThe sale stands; documents are missing and need a manual fix
A duplicate callback arrivesNo second invoice; existing ones are returned
The Order was freeNo invoices, ever
A refund exceeds the invoiceImpossible; refunds are capped at the Order total
The buyer has no tax identifierThe invoice is issued without one; billing details are optional

An invoice for a cancelled but unrefunded OrderIt stays issued; the refund is what creates a credit note
