GST Billing & Accounting Software for Small Business in India

Running a small business means doing the books, chasing payments, filing GST and minding stock — usually all by yourself, on a tight budget, with no IT team. KukBook puts billing, full double-entry accounting, inventory, GST returns and CRM in one cloud platform so you stop stitching together separate apps and spreadsheets. It's GST-ready out of the box, keeps working as an offline PWA when the internet drops, and starts free for 90 days with no credit card. Built for SMBs across India and the GCC, priced in rupees, with GST and GCC VAT compliance built in.

One platform instead of separate apps

GST billing, double-entry accounting, inventory, CRM and HRMS live together — no juggling separate tools or paying for each one. Less to learn, less to reconcile, one login.

GST and e-invoicing handled

Raise GST-compliant invoices, generate e-invoices with IRN and QR, create e-way bills, and prepare GSTR-1 and GSTR-3B straight from your billing data — no separate filing tool or manual re-keying.

See your cash and dues clearly

Bank reconciliation, customer statements, automatic payment reminders and 40+ financial reports show exactly who owes you and where your money stands.

No IT team or server needed

It's cloud software — nothing to install or maintain. Import your existing data from Tally XML or Excel/CSV, run it on any device through a browser, and keep working offline as a PWA that syncs when you reconnect.

Priced and built for SMBs

Rupee pricing, a 90-day free trial with no credit card, and GST plus GCC VAT compliance — so you can start small and add modules only as you grow across India and the GCC.
