GST and returns
This describes what the software does with GST. It is not tax advice โ which rate applies to your goods or services, and what you are obliged to file, are questions for your accountant.
How the tax head is decided
The state on your billing profile is compared with the state on the customer record. Different states mean the full rate is applied as IGST; the same state means the rate is split into equal CGST and SGST halves.
This happens on every invoice, so the decision is never left to memory.
Available rates
0, 0.25, 3, 5, 18 and 40 percent. The 12 and 28 percent slabs were abolished in September 2025 and are not selectable anywhere in the product, which prevents an obsolete rate reaching a new invoice.
GST is always exclusive: the rate is applied on top of the taxable value you enter.
HSN and SAC codes
A bundled code database is searchable while you build a line item, covering goods and services. Choosing the right code for what you sell is a judgement call your accountant can confirm.
TDS and TCS
On the plans that include them, TCS can be applied on an invoice and TDS deducted when recording a payment. Both carry configurable maximum rates so an out-of-range figure is rejected rather than stored.
Return data
GSTR-1 data can be exported and GSTR-3B figures summarised from the invoices you raised, so filing works from your billing records rather than a re-keyed copy.
The software produces the data. Filing still happens on the GST portal.
E-invoicing and e-way bills
On the plans that include them, e-invoice IRNs and e-way bills can be generated once the relevant government credentials are configured for your account.
