GST billing
GST billing software for restaurants, correct to the paisa.
ZaikaLab prints GST bills with CGST and SGST split, sequential invoice numbers per outlet per financial year, and reports by rate that match what you file.
Three schemes, one setting
Regular, composition or no tax: pick once, bill right
Set the outlet’s GST scheme once during setup. Every bill after that follows it: the tax lines, the title on the bill and the reports.
Integer paise, never floats
Every amount is held in whole paise, so no rupee value drifts by a fraction on a bill or in a report.
Half-up rounding, once per bill
Lines are worked to the paisa, and the bill is rounded once at the end with the round-off printed as its own line.
CGST plus SGST always equals the tax
The tax is split into CGST and SGST so the two halves always add back to the whole, paisa for paisa.

Inclusive or exclusive
Inclusive or exclusive prices, the same correct bill
Menu prices with GST inside, or added on top: one setting per outlet, and the bill shows the taxable value either way.
- Inclusive prices are worked back to the taxable value, line by line.
- Exclusive prices add CGST and SGST on top of the subtotal.
- Item-wise rates, with the breakup printed by rate.
Composition and no tax
Composition and unregistered outlets
Composition dealers print no tax lines; an unregistered outlet prints none at all, and the reports say so.
- A composition bill is titled Bill of Supply and carries the note the law asks for.
- An outlet that is not GST registered prints a plain bill with no GSTIN on it.
- Changing the scheme keeps one invoice series; nothing forks or starts again.
Invoice numbers
Invoice numbers in sequence, per outlet, per financial year
The counter assigns the next number inside the billing step itself, so two bills never share one and none is skipped. A new series starts on 1 April.
- A cancelled bill keeps its number and shows in the reports.
- An edited bill becomes a revised bill with the next number.
- One series for every document, whatever the scheme.
