Invoicing Software Built for Freelancers

You do the work; getting paid for it shouldn't be the hard part. KukBook gives freelancers and independent professionals clean GST-ready invoicing, automatic payment reminders that follow up on late clients for you, and a customer portal where clients can view their invoices. With full accounting and 40+ financial reports behind it, you can see what you earned, what's outstanding and your real profit — without spreadsheets or a separate accountant. Start free for 30 days, no credit card.

Get Paid On Time

Set automatic payment reminders so polite follow-ups go out on overdue invoices without you having to chase. A customer portal lets clients view and track their invoices, and customer statements show exactly who still owes you.

Invoicing That's Actually Simple

Raise a professional GST/VAT invoice in minutes — or start from an estimate or proforma and convert it into a final invoice. Ideal for project quotes, advances and milestone billing on client work.

GST on Your Services, Sorted

KukBook generates compliant GST invoices and your GSTR-1 and GSTR-3B returns, so filing on your service income stops being a quarterly panic. If you bill GCC clients, VAT-compliant invoicing is covered too.

Full double-entry accounting and 40+ financial reports let you record business costs against your income, so you can see actual profit — not just what landed in your bank this month.
