What you get

GSTIN on every invoice

Add your GSTIN and your customer’s GSTIN so each invoice carries the details your buyers and accountant expect.

HSN / SAC codes

Maintain tax codes once and apply them to items and services, so invoices stay consistent.

CGST, SGST and IGST

Set up intra-state and inter-state tax rates and apply them per line, instead of calculating splits by hand.

Invoices in INR

Bill in rupees with Indian number formatting. Taxes, totals and balances are shown in INR.

Electronic invoicing

Issue invoices as PDFs, email them from the platform and share a payment link, so customers can pay in a tap.

Connected to accounts and CRM

Invoices flow into InEx accounting and your customer records. No re-typing into a separate tool.
