The Challenge

Small and mid-sized Indian businesses still create invoices in Word, Excel or old desktop software. GST calculations, e-invoice (IRN) and e-way bill generation are manual and error-prone, and owners have no clear view of outstanding payments or profitability.

What We Built

We designed and built Invollo, a multi-company invoicing SaaS. Businesses create branded GST invoices in under a minute, generate e-invoices and e-way bills directly from the platform, share invoices by link, and track clients, products, expenses and outstanding payments in one place.
