Question 1

Do I need GST to send a party invoice?

Accepted Answer

No. You can issue an Estimate or a Bill of Supply without GST. Tax Invoice mode requires a valid GSTIN on the outlet.

Question 2

What must a catering invoice include in India?

Accepted Answer

Under CGST Rule 46 a Tax Invoice needs the supplier name, address, GSTIN, invoice number, date, party name, party address (if GST), description of service, taxable value, tax rate, tax amount, and total. Orderzy Invoice Book renders every field automatically from your outlet profile.

Question 3

What is the difference between a tax invoice and a bill of supply?

Accepted Answer

A Tax Invoice is issued by a GST-registered supplier for taxable supplies. A Bill of Supply is issued when GST does not apply - either the supplier is unregistered, is on the composition scheme, or is supplying exempt goods or services.

Question 4

Can I issue an advance receipt for a party booking?

Accepted Answer

Yes. Restaurant supply is a service, so GST is chargeable at the time of advance receipt. Orderzy Invoice Book supports the Advance Receipt kind, then subtracts the advance on the final invoice so the customer is not double-billed.

Question 5

What is the format for a bulk order invoice in India?

Accepted Answer

The same format as any Tax Invoice - CGST Rule 46 fields plus per-line description, quantity, unit price, and taxable value. Orderzy Invoice Book lets you edit the unit price per line so party rates and bulk rates never touch your menu prices.

Question 6

Can I generate an invoice without a POS system?

Accepted Answer

Yes. Orderzy Invoice Book runs in your browser - no POS hardware, no separate accounting software. Sign in, fill three steps, issue. The PDF, WhatsApp send, and email send are all inside the same screen.

Question 7

What is a gapless serial number and do I need one?

Accepted Answer

A gapless serial is one where every issued number is used exactly once and the sequence never skips. Under GST every tax invoice must carry a unique consecutive serial. Orderzy assigns the number inside a database transaction so a crash or a rollback never burns a slot.

Question 8

How do I send an invoice on WhatsApp legally?

Accepted Answer

Send the invoice PDF through the Meta Cloud API using a Meta-approved template. Orderzy sends via a template named invoice_book_issued_v1 with the PDF attached as a document. Recipients see it in their normal WhatsApp chat.
